Abstract

Recording media which record data using holography have an expiry date (shelf life) in a state in which no recording has been made to a recording layer. Data cannot be recorded on recording media after the expiry date, and therefore the amount of data that can be recorded in a storage system is reduced. The objective of the present invention is to provide a storage system with which recording media can be used without waste. A storage system provided with a storage device and a management server is characterized in that the storage device is provided with: a first storage which houses a plurality of portable recording media having expiry dates; a recording and reproducing unit which records data on the portable recording media housed in the first storage, and reproduces the recorded data; and a conveying unit which conveys the portable recording media between the first storage and the recording and reproducing unit. The storage device transmits the expiry dates of the portable recording media housed in the first storage to the management server, and the management server retains the received expiry dates of the portable recording media.

Description

Storage system

The present invention relates to a storage system.

There is JP-A-5-46994 (Patent Document 1) as background art in this technical field. In this gazette, “the information on the date of manufacture of the information recording medium and the useful life of writing and the information on the current date and time are held, and when recording data on the information recording medium, the useful life of writing is checked, If it exceeds, a write-prohibited error signal is returned to the host computer. "

Japanese Patent Laid-Open No. 5-46994

A recording medium that records data using holography (hereinafter referred to as a holographic disk) has an expiration date (shelf life) when the recording layer is in an unrecorded state. Since a holographic disk whose expiration date has expired cannot record data normally, such as when an error occurs during recording, it must be discarded so as not to be recorded.

Therefore, when a storage system using a holographic disk is introduced, depending on the installed capacity of the holographic disk, the expiry date will be reached before consuming all the holographic disk (by discarding the holographic disk that has expired). There is a problem that the recordable data capacity is reduced.

An object of the present invention is to provide a storage system that can use an unused holographic disk without waste.

In order to solve the above problems, for example, the configuration described in the claims is adopted.

According to the present invention, it is possible to provide a storage system that prevents the expiration date of unused holographic disks in advance and guarantees the system capacity.

Issues, configurations, and effects other than those described above will be clarified by the following description of the embodiments.

Next, a procedure for archiving data stored in the block storage 306 of the business server 20 or the host computer 30 to the data library system will be described with reference to the drawings.

In this embodiment, first, the user uses the archive management server 40 to create an archive policy related to archive execution in advance.

Specifically, the user selects the policy creation function using the user I / F unit 403 from the menu screen output to the display device 102 by the archive management server 40 using the external display control unit 408.

Then, the CPU 401 notifies the policy management unit 410 to that effect, and the policy management unit 410 displays it via the external display control unit 408 in order to set parameters necessary for new addition to the policy management table 1100. A policy information setting screen is output to the device 102.

The user uses the user I / F 403 to input parameters necessary for executing the archive on the displayed policy information setting screen.

The policy management unit 410 that has received the parameter registers it in the policy management table 110 as a new archive policy.

Thereby, the job execution management unit 411 of the archive management server 40 periodically refers to the contents of the policy management table 110, generates a job to be scheduled, and registers it in the job management table 1200. In this case, the status 1208 of the job is “waiting”.

Next, a case where the time of the entire system shown in FIG. 1 reaches the scheduled execution start time 1206 of the archive policy job registered in the job management table 1200 will be described.

When the scheduled execution start time 1206 is reached, the job execution management unit 411 notifies the hierarchy management processing unit 409 of the policy ID 1101 corresponding to the archive policy registered in the policy management table 1100 via the CPU 401, and executes the archive execution. To instruct.

The hierarchy management processing unit 409 acquires the corresponding policy ID 1101 in the policy management table 1100 and stores it in the location indicated by the migration source 1103-in the present embodiment, the location indicated by the corresponding data path in the block storage 306 of the business server 20. From among the files that have been selected, a file corresponding to the rule 1105 is selected as an archive target. At this time, the hierarchy management processing unit 409 may operate in cooperation with the hierarchy management processing unit 310 and the file management unit 311 of the business server 20.

Then, the hierarchy management processing unit 409 reads the file selected as the archive target from the hierarchy management processing unit 310 of the business server 20, and the location indicated by the migration destination 1104—in this embodiment, the block storage of the data library system 10 The transmission to the location indicated by the corresponding data path in 101 is instructed. Similarly, the hierarchy management processing unit 208 of the server 100 in the data library system 10 is instructed to archive data transmitted by the hierarchy management processing unit 310 of the business server 20.

Thereby, the hierarchy management processing unit 310 of the business server 20 and the hierarchy management processing unit 208 of the server 100 transmit and receive the selected file between the host IF unit 304 and the host IF unit 205.

Next, processing for receiving data recorded by the data library system 10 from the hierarchy management processing unit 310 of the business server 20 via the host IF unit 304 and recording the data will be described.

FIG. 16 is a flowchart of data recording in the data library system 10.

S1601 is an operation of receiving data from outside the system, and the transmission source is the business server 20 connected to the data network 11. The CPU 201 of the server 100 receives data together with a recording request from the business server 20 via the host IF unit 205. The recording request is, for example, a network file system (NFS) file creation and file writing request.

Received data is once recorded in the block storage 101. Among the recording requests, for example, in the case of NFS, file name, directory path name, access authority information, owner identifier, belonging group identifier, time information, file identifier, file capacity information, data offset information, or other data Contains information about. In the above description, NFS is described as an example, but other protocols such as CIFS may be used.

In S1602, the CPU 201 of the server 100 notifies the file management unit 207 and the hierarchy management processing 208 that the received data has been recorded in the block storage 101. The file management unit 207 creates a data identifier 1001, a data size 1002, a data path 1003, an access time 1004, and an access authority 1005 regarding the received data in the data management table 1000. The hierarchy management processing unit 208 monitors whether or not the file recorded in the block storage 101 corresponds to the migration policy managed by itself.

Here, the migration policy has one condition, for example, when a certain period of time has elapsed after recording in the block storage 101, when the number of files exceeds a predetermined number, or when the capacity of a file reaches one optical disk. The combined contents are shown below.

S1603 is an operation of selecting the portable recording device 103 when it matches the movement policy in S1602, and the hierarchical management processing unit 208 refers to the system configuration management table 900 according to a command from the CPU 201 and receives the data received in S1601. Is selected. As a selection method, the portable storage devices 103 are used in order so that the remaining capacities of the portable recording devices 103 are substantially the same, or after recording in one portable recording device 103, the next portable recording device 103 is selected. There are ways to do it. Thereafter, the hierarchy management processing unit 208 refers to the system configuration management table 900, and the recording medium storage unit 111 used for data recording from the one or more recording medium storage units 111 set in the selected portable recording device 103. Select.

In step S1604, the data recording / reproducing unit 110 used for data recording is selected. As a selection method, referring to the portable recording device configuration management table 800 or the system configuration management table 900 of the selected portable recording device 103, a method of selecting a drive with a normal status and no disc set, or each data There is a method of selecting at random such that the operating rate of the recording / reproducing unit 110 is flattened. By selecting in this way, it is possible to prevent the usage time of the data recording / reproducing unit, and it is possible to prevent a specific data recording / reproducing unit from failing first.

In step S1605, an optical disk on which data is temporarily stored in the block storage 101 is selected from a plurality of optical disks stored in the recording medium storage unit 111 in the portable recording device 103 selected in step S1603.

In step S1606, the library control unit 211 transmits the data recording command to the portable recording device 103 selected in step S1603. The data recorded in the block storage 101 by the instruction of the CPU 201 is transferred to the portable recording device 103 via the library I / F 203 and recorded on the optical disc 113.

In step S <b> 1607, the CPU 201 receives the processing result for the recording command from the portable recording device 103. If data recording has failed, the process advances to step S1608. If successful, the data recording is terminated.

S1608 is a process in the case where the data recording is not normally completed, and determines whether or not the number of times the same data has been recorded on the optical disk has reached a predetermined number. If not reached, the process proceeds to S1605. If reached, the process proceeds to S1609.

In step S1609, an error message is displayed on the display device 118 via the external display control unit 206, or the error content is stored in the memory 202 or the block storage 101 as a log. Depending on the content of the error received from the portable recording device 103, an error message is output to the display device 118 via the external display control unit 206, or the error content is logged to the memory 202 or the block storage 101. Store.

In this example, when the data recording is not completed normally, an error is notified and the process is terminated. However, when a plurality of portable recording devices 103 are connected, a portable recording device or the like is used. The data may be recorded by selecting. When such an error avoidance process is put in, the reliability of the data library system becomes higher.

FIG. 17 is a flowchart of data recording of the portable recording device that has received a recording command from the library control unit 211.

In S1701, the portable recording device 103 that has received a recording command from the server 100 selects an optical disk on which data is to be recorded. The optical disk selection process will be described in detail with reference to FIG.

In S1702, the process branches depending on whether the optical disk has been selected. If it can be selected, the process proceeds to S1703, and if it cannot be selected, the process proceeds to S1705.

S1703 is a process of recording data on the selected optical disk. The CPU 104 controls the recording medium transport unit 114 to transport and insert the optical disk 113 from the storage position of the recording medium storage unit 111 in which the selected optical disk 113 is stored into the data recording / reproducing unit 110. Then, the data received via the server I / F unit 107 is sent to the data recording / reproducing unit 110 and recorded on the optical disc. The selection method of the data recording / reproducing unit 110 is not particularly defined here, but for example, the data recording / reproducing unit is selected so that the usage time of each data recording / reproducing unit is approximately the same. By selecting in this way, it is possible to prevent the usage time of the data recording / reproducing unit, and it is possible to prevent a specific data recording / reproducing unit from failing first.

In S1704, the process branches depending on whether the data recording has been completed normally. In the case of normal end, the process proceeds to S1706. Otherwise, the process proceeds to S1705.

In S1705, an error response is generated according to the content of the error. The optical disc could not be selected because there was no unused disc, the failure to select the optical disc, the recording failure that failed in data recording, the data recording / reproducing device 110 during the data inspection of the optical disc 113, the recording quality or the data reproduction There is an error such as failure of inspection when inspection fails.

In S1706, the CPU 102 updates the information in the storage unit 112 with the data recording result. That is, the value of the medium state 712 corresponding to the optical disc selected in S1702 is updated with the data recording result. Specifically, the value of the medium state 712 is the recording completion when the data recording and inspection are normally completed, the recording failure when the data recording fails, and the inspection failure when the inspection fails.

In S1707, the processing result of data recording is transmitted to the server 100, and the process is terminated.

FIG. 18 is a flowchart of the disk selection process of the portable recording device 103.

In this example, the recording media stored in the recording medium storage unit 111 are used in order from the smallest slot number.

In S1801, the confirmation slot number N for confirming whether or not to select the data recording optical disk 113, the confirmation slot number Nc of the recording candidate disk, and the initial value of the expiration date Lc of the recording candidate disk are set. N stores the value of the slot number of the first slot or the slot number stored in the optical disk used in the previous recording in the memory 202 or the like, and sets the next slot number. Nc is set to a value that cannot be taken as a slot number in order to identify the case where no disk is selected. Lc sets an expiration date longer than the maximum expiration date of the optical disk, such as 10 years.

In S1802, the CPU 102 reads the presence / absence of the medium of the confirmation slot number N and the value of the medium state from the storage unit 112. If the presence / absence of the medium is “present” and the medium state is “unused”, the process advances to step S1805. Otherwise, the process proceeds to S1803.

In S1803, the process branches depending on whether all slots have been confirmed. If NO, the next slot is set as the confirmation target in S1804, and the process returns to S1802 to confirm whether the optical disk in the slot N can be used as a recording disk. If all slots have been confirmed, the process ends.

In S1804, the value of the confirmation slot number N is increased by 1 because the optical disk stored in the next slot is to be confirmed.

In S1805, the expiration date L (N) of the confirmation slot number N is acquired.

Confirm whether the expiration date L (N) acquired in S1806 has expired. If the expiration date has expired, the process proceeds to S1807; otherwise, the process proceeds to S1808.

In step S1807, the CPU 102 updates the medium status value of the optical disc to “expired” and proceeds to step S1803.

In S1808, the expiration date L (N) acquired in S1806 is compared with the expiration date Lc of the recording candidate disk. If the expiration date L (N) is shorter than the expiration date Lc of the recording candidate disc, the process proceeds to S1809; otherwise, the process proceeds to S1803.

In S1809, information on the recording candidate disk is updated. Since it is determined that the expiration date L (N) of the optical disc stored in the confirmation slot number N is shorter than the expiration date Lc of the recording candidate disc in S1808, the optical disc optical disc becomes a recording candidate disc. The value of the expiration date Lc of the recording candidate disk is set to the confirmation slot number N. Further, the expiration date Lc of the candidate disk is set to the expiration date L (N). Then, the process proceeds to S1803 to confirm the optical disk stored in the next slot.

Through the above processing, the slot number of the optical disk with the shortest use period is set as the recording candidate disk slot number Nc. If there is no recordable optical disk, the value of the record candidate disk slot number Nc remains the initial value.

In the case where a plurality of recording medium storage units 111 are provided, this processing is performed for all the recording medium storage units 111.

According to the above procedure, data can be recorded on a disc that has not expired with another optical disc 113 without being recorded on the optical disc 113 that has expired.

Upon receiving the data recording result from the portable recording device 103, the hierarchy management processing unit 208 of the server 100 notifies the result to the hierarchy management processing unit 310 of the business server 20 or the hierarchy management processing unit 409 of the archive management server 40. To do.

The tier management processing unit 310 of the business server 20 or the tier management processing unit 409 of the archive management server 40 that has received the data recording result only stores the data in the block storage 306 of the business server 20 when the recording result is successful. Stubbing and deleting the data body.

Then, the hierarchy management processing unit 409 of the archive management server 40 writes “end (success or failure)” to the status 1208 of the job management table 1200 via the job execution management unit 411 or directly.

The job execution management unit 411 outputs the execution result to the display device 102 via the external display control unit 408 as necessary.

As described above, in this embodiment, it is possible to prevent data from being recorded on an expired optical disc by managing the expiration date of the optical disc. Further, by using the optical disk from the one with the short expiration date, it is possible to reduce the number of disks that have expired without being recorded.

In the present embodiment, a process for collecting the medium expiration date of the optical disc will be described in order to centrally manage the expiration date of the optical disc stored in the portable recording device 103 to which the server 115 is connected.

FIG. 19 is a flowchart showing an example of a medium expiration date collection process of the optical disc 113.

S1901 is processing for detecting the connection of the portable recording device 103. When the portable recording device 103 is connected to the data library system 10, it notifies the server 100 of the connection. The server 100 detects the notification and causes the configuration management unit 208 to start collecting the medium usage time limit of the optical disk 113.

In S1902, the configuration management unit 210 confirms whether the connected portable recording device 103 is registered in the system configuration management table 900. If unregistered, the process proceeds to S1903, and if registered, the process proceeds to S1904.

In S1903, when the portable recording device 103 is not registered in the system configuration management table 900, the configuration management unit 208 collects information of the portable recording device 103 connected via the library I / F unit 203. Specifically, from the portable recording device configuration management table 800 and the recording medium storage table 700 of the portable recording device 103, all of the portable recording device IDs 801 of the portable recording device 103 and all of the portable recording devices 103 mounted. The information includes the storage medium storage unit ID 701 of the storage medium storage unit 111, the slot number 711 of all the optical disks stored in each storage medium storage unit 111, the medium state 713, and the medium expiration date 714. The acquired information is registered in the optical disc management table 2100 shown in FIG. The acquired disk ID 2101, library ID 2102, and recording medium storage unit ID 2103 are stored.

Here, the disk ID 2101 may be determined uniquely by the data library system 10. The current position 2104 and the storage position 2105 store slot numbers. The medium state 2106 stores the medium state, and the medium use period 2107 stores the acquired medium use period. The offline 2108 is a value indicating whether the optical disk is connected to the data library system. Since it is information of the portable recording device 103 that detected the connection, it is set to “online”. When the information is registered in the database, the process is terminated.

In S 1904, when the portable recording device 103 is registered in the system configuration management table 900, the configuration management unit 210 is registered in the disk management table 2100 in the portable recording device 103 via the library I / F unit 203. It is confirmed whether there is a recording medium storage unit 111 having a storage medium storage unit ID that is not present. When the capacity of the recording medium storage unit 111 stored in the portable recording device 103 becomes FULL, the recording medium storage unit 111 with the capacity set to FULL is taken out, and a new recording medium storage unit 111 is inserted. Cases occur. If YES, the process proceeds to S1905. If NO, the process proceeds to S1906.

In S1905, information is collected and registered for the recording medium storage unit 111 having a storage medium storage unit ID that is not registered in the disk management table 2100. Information to be collected and registration processing are the same as in S1903.

In S1906, contrary to S1905, the case where the recording medium storage unit 111 having the storage medium storage unit ID registered in the database is not stored in the portable recording apparatus 103 is confirmed. This corresponds to the extracted recording medium storage unit 111 described in S1904. If NO in S1907, the process ends.

In S1907, the value of the medium state 110 corresponding to the storage medium storage unit ID of the recording medium storage unit 111 is set to “offline”.

FIG. 20 is a flowchart showing an example of an update process of the optical disc management table 2100 when the separation is detected.

Specifically, the processing is performed when the portable recording device 103 is detached.

In step S2001, the removal of the portable recording apparatus 103 is detected. The portable recording device 103 and the server device regularly exchange connection confirmation signals in order to detect the connection state between them. If the connection confirmation signal cannot be received for a predetermined period, the server 100 determines that the portable recording device 103 has been detached.
The CPU 201 of the server 100 detects the detachment and causes the configuration management unit 210 to start update processing of the optical disc management information 2100 of the optical disc 113.

In S2002, the configuration management unit 210 refers to the optical disc management table 2000 and sets the value of the medium state 110 corresponding to the data library ID of the detached portable recording device 103 to “offline”.

Here, the configuration management unit 210 manages the expiration date of the optical disk of the entire data library system. By confirming the “medium expiration date” in the optical disc management table 2100 at a predetermined frequency such as once / day, it is possible to confirm whether the optical disc including the offline optical disc has expired.

When the “expiration date” is recognized, the CPU 201 is notified with the disc ID, recording medium storage unit ID, and data library ID of the expired optical disc. Receiving the expiration date notification, the CPU 201 uses the external display control unit 206 to display the occurrence of an expired optical disc on the display device 118 to notify the user. It also notifies that the recording capacity of the data library system 10 has decreased due to the expiration of the optical disk.

In addition, when the remaining “medium expiration date” satisfies a predetermined condition such as within six months, the user may be informed that there is an optical disk that is close to “expiration date”. By informing the user in advance, it can be expected to reduce the number of discs whose “expiration date” remains “unused”.

Further, in FIG. 18, the portable recording device 103 side selects a disk to be used for recording, but the CPU 201 extracts from the configuration management unit 210 one or more optical disks that are near the expiration date in the portable recording device 103. In addition, information regarding the extracted optical disc may be notified to the portable recording device 103 via the library I / F unit 203. The CPU 104 of the portable recording device 103 that has received the information about the optical disc refers to the information and uses the disc that is actually used for recording as appropriate (for example, if there is one candidate, use that disc, and if there are multiple candidates, If there is a disk with a small slot number, etc.)

As described above, the server 100 can manage the medium state and medium expiration date of all the optical disks of the portable recording device 103 connected to the data library system 10.

Thereby, it is possible to record data by selecting the optical disk with the shortest expiration date from among all the optical disks that are not expired, among all optical disks.

FIG. 21 shows an example of the optical disc management table 2100.

The optical disk management table 2100 records information of a disk ID 2101, a data library ID 2102, a recording medium storage unit ID 2103, a current position 2104, a storage position 2105, a medium state 2106, a medium expiration date 2107, and offline 118 for each of the optical disks 113. Database table.

The table 2100 is an optical disk stored in the optical disk storage device when the optical disk storage device is connected to the data library system of the present invention for the first time, or once connected to another data library system. Information of 113 is registered or updated. Further, it is updated when the optical disk 113 is moved between the data recording / reproducing apparatus 110 and the optical disk storage apparatus 111.

The disk ID 2101 is a character string or a number for identifying each optical disk 113. The ID is an ID that is individually identifiable recorded at the time of manufacturing the optical disc 113, is generated based on the ID, or is uniquely determined by the data library system of the present invention.

The data library ID 2102 is an ID for identifying the portable recording device 103. In the disk table 1100, the data library ID of the data library 101 containing the optical disk 113 in the same row is recorded.

The recording medium storage unit 2103 is a character string or a number that identifies the recording medium storage unit 111. The ID is determined and recorded in the storage unit 112 attached to the recording medium storage unit 111 before the recording medium storage unit 111 is manufactured or shipped. The CPU 102 reads the ID from the storage unit 112 when it is registered or updated in the database table.

The current position 1104 indicates the current position, and a character string or a number that is an address in the data recording / reproducing apparatus 110 or the recording medium storage unit 111 at the position where the optical disk 113 in the same row is present is recorded.

The storage position 1105 indicates a storage position, and a character string or a number that is an address in the recording medium storage unit 111 in which the optical disk 113 in the same row is to be stored is recorded. The storage position is a position in the recording medium storage unit 111 in which the optical disk 113 is stored at the time of shipment.

By storing a specific position as a storage position, the server 100 and the portable recording device 103 are disconnected due to a power failure or a network failure, and the portable recording device 103 is unable to notify the server 100 of the position information of the optical disc 113. However, in order to prevent damage to the apparatus, the server 100 will not lose sight of the optical disk 113 if the portable recording apparatus 103 returns the optical disk 113 being transported to its original position.

In the above description, the position stored at the time of shipment is set as the storage position 2105. However, when the optical disk is discarded or the terminal 120 or the like requests the storage position 1105 to be changed as a user request, the storage position 2105 is shipped. Sometimes changed from the stored position. Further, the storage position 2105 may be changed in order to rearrange according to the frequency of the conveyance request of the optical disk 113.

The medium state 2106 is a processing state, and the state of the optical disk 113 in the same row is recorded. The state 2106 includes “unused”, “reserved”, “recording”, “recording failure”, “inspection”, “inspection failure”, “recording completion”, “reproducing”, “offline”, “unknown medium”, “expired” It has.

“Unused” indicates that the optical disk 113 in the same row is unused and data can be recorded. “Reservation” indicates that the optical disk 113 in the same row is reserved for the allocation process. “Recording” indicates that the assignment process has been completed and the data recording / reproducing apparatus 110 is actually recording data on the optical disc 113. “Recording failure” indicates that the data recording / reproducing apparatus 110 has failed in recording data on the optical disk 113. “During inspection” indicates that the data recording / reproducing apparatus 110 is in the middle of inspection. “Inspection failure” indicates that the data recording / reproducing apparatus 110 has failed during the data inspection of the optical disc 113 due to an abnormality in recording quality or data reproduction. “Recording complete” indicates that the recording and inspection have been completed normally. “Reproducing” indicates that the data recording / reproducing apparatus 110 is reproducing data from the optical disc 113. “Offline” indicates that the optical disk 113 is removed from the data library system and is offline. “Unknown medium” indicates that the disk stored in the slot cannot be recorded / reproduced by the data recording / reproducing apparatus 110. “Expiration date” indicates that the optical disk 113 stored in the slot has expired without being used, and data cannot be recorded.

The medium expiration date 2107 is an expiration date for recording data on an unused optical disk. Set by the manufacturer of the optical disc.

The optical disk management table 2100 for managing the optical disk 113 is used for selecting an optical disk when the data library system causes the portable recording device to perform recording and reproduction on the optical disk by managing various information on the optical disk 113. It is done.

Also in this embodiment, it is possible to prevent data from being recorded on an optical disk whose use has expired by managing the use period of the optical disk. Further, by using the optical disk from the one with the short expiration date, it is possible to reduce the number of disks that have expired without being recorded.

As described above in the first and second embodiments, the optical disk 113 set in the recording medium storage unit 111 in the portable recording apparatus 103 has a use expiration date in an unused state. Therefore, for example, in the system shown in FIG. 1, if the number of recording medium storage units 111 set in the portable recording device 103 of the data library system 10 is large, the optical disk 113 is recorded before data is recorded on all the optical disks 113. Expires and the optical disc becomes unusable. That is, this means that the capacity of the data library system 10 is reduced.

To prevent the above, (1) when the data library system 10 is introduced into the system, it is necessary to appropriately estimate the number of recording medium storage units 111 to be set in order to prevent expiration. Furthermore, (2) it is necessary to generate an operation plan related to capacity addition after system introduction considering the expiration date of unused media.

In this embodiment, the following methods are provided in order to solve the above (1) and (2).

In this embodiment, it is assumed that the customer newly introduces the data library system 10 in the state where the data library system 10 does not exist in the system shown in FIG. 1, and the block storage 101, the recording medium are used with reference to FIG. A necessary capacity estimation process of the storage unit 111 will be described.

FIG. 22 is a flowchart showing an example of the capacity estimation process. In S2201, the user uses the user I / F unit 503 and the external display control unit 508 to output the operation menu screen of the device management server 50, and selects “capacity estimation calculation”. Here, the storage configuration subject to capacity estimation needs to be registered in the configuration management unit 510 in advance by means such as addition to the configuration information setting file or program addition / correction. In this example, it is assumed that the data library system 10 does not exist. Therefore, one component of the data library system 10 includes a server 100, a block storage 101, and a portable recording device 103 (minimum number and maximum number). Is registered in the configuration management unit 510 in advance. Furthermore, the capacity calculation method of the data library system 10 needs to be registered in advance in the capacity calculation execution unit 514 by means such as addition to a calculation algorithm file or program addition / correction. The capacity calculation execution unit 514 is activated to instruct execution of capacity estimation calculation.

The capacity calculation execution unit 514 outputs a setting screen for information necessary for capacity estimation via the external display control unit 508, and inputs storage information for capacity estimation to the user or from candidates displayed by a pull-down menu or the like. Get selected. For example, the estimation target device “data library system” type name “AA”, “1 system”, etc.

In S2202, the capacity calculation execution unit 514 acquires the job management table 1200 from the job execution management unit 512 and the capacity management table 1500 from the capacity management unit 511, and calculates the data generation amount of the entire system shown in FIG. For example, it is calculated from the amount of data transmitted from the host computer 30 to the business server 20 in the recent month, or the amount of increase or decrease in data from the previous month of the free capacity of each device acquired every month.

In step S2203, the capacity calculation execution unit 514 acquires the job management table 1200 from the job execution management unit 411 of the archive management server 40 connected via the management I / F unit 506 and the policy management table 1100 from the policy management unit 410. The amount of data that has been backed up / archived is calculated. For example, as shown in the archive execution analysis report screen 1300 in FIG. 13, it is grasped by the capacity consumption for the most recent month and which policy is executed for each storage device.

In step S2204, the capacity calculation execution unit 514 confirms the type of storage used in step S2201. If the type is the portable recording device 113, the process proceeds to step S2205. Otherwise, the process proceeds to step S2206.

In S2205, when the storage type is the portable recording device 113, the capacity calculation execution unit 514 acquires information on the expiration date of the optical disk 113 to be used. For example, it is the number of years of expiration date (for example, 3 years, 5 years, etc.) that is guaranteed because it is the manufacturer or standard of the optical disk 113. At this time, the user inputs the expiration date of the optical disk that can be purchased according to the introduction time using the user I / F unit 503 and the external display control unit 508, or the manufacturer or provider of the optical disk via the network. There is also a method of obtaining in advance by means such as obtaining from.

In S2206, the capacity calculation execution unit 514 uses the above-mentioned 2202 and 2203 as input values common to all storages, and further adds S2205 as an input value only in the case of the portable recording device 113, and the expected capacity consumption over time. Is calculated. For example, as shown in FIG. 23, the ratio of the archive execution amount (Va) acquired in S2203 to the transition of the _total data generation amount (Vtotal) acquired in S2202 (Sa = Va ÷ _Vtotal × 100 ). Then, it is determined whether or not the archive execution amount is increased, and the data amount to be allocated to the data library system 10 is determined. Then, the elapsed time on the horizontal axis and the planned consumption on the vertical axis are used to calculate how the consumption capacity increases. In the case of a portable recording apparatus, the expiration date (TL) of the unused medium acquired in S2205. Therefore, the capacity (VL) or less consumed from the time of introduction to the expiration date (TL) is regarded as the necessary capacity.

Regarding the calculation of the amount of data to be allocated to the data library system 10, in addition to the above, when the storage 1 of the archive execution analysis report screen 130 in FIG. 13 is a portable recording device, the disk consumption (all policies) 1302 is 6 The monthly average is 65 GB. This may be used as it is, or a six-month average consumption may be calculated from the capacity management table 1500, and the average of these may be calculated, and the calculation method is not limited.

Based on the calculated capacity (VL) of the data library system 10, the number of portable recording devices 103, the capacity of the block storage 101, the cost, and the like are calculated.

In step S <b> 2207, the capacity calculation execution unit 514 performs regular maintenance (parts) scheduled for each device of the system in FIG. 1 by the maintenance plan creation / management unit 611 of the maintenance server 60 via the maintenance I / F unit 507. Replacement or periodic maintenance) plan is acquired, whether there is any scheduled maintenance near the expiration date (TL) of S2206, and a capacity addition schedule that matches the schedule of the regular maintenance is created as much as possible. . The created capacity addition schedule is stored in the maintenance plan creation / management unit 611 of the maintenance server 60. If necessary, the capacity addition schedule is notified to the job execution management unit 512 of the device management server 50 via the maintenance I / F unit 606, and the device management server 50 also grasps the capacity addition timing. It may be possible.

In S2208, the capacity calculation execution unit 514 outputs the necessary capacity calculated in S2206 and the next capacity addition plan created in S2207 to the display device 102 using the external display control unit 508, as shown in FIG. .

According to the above procedure, when the data library system 10 is introduced into the system, the number of recording medium storage units 111 to be set can be appropriately estimated, and useless capacity consumption due to expiration can be prevented.

Here, in FIG. 22, generation of a capacity addition plan after introduction is executed immediately after performing capacity estimation for preventing expiration when the data library system 10 is introduced, but the latter may be implemented at another timing. .

In addition, the data library system 10 sets an optical disk with the same expiration date in one recording medium storage unit 111 or one portable type in order to facilitate capacity estimation at the time of introduction and management of capacity addition after introduction. Equipped with a mechanism such as using a recording medium storage unit 111 in which optical disks having the same expiration date are built in the recording device 103, or making the expiration dates of optical disks in all portable recording devices 103 connected at the time of introduction, etc. There is also a way to do it.

Furthermore, in this embodiment, the capacity estimation at the time of introduction is executed by the capacity calculation execution unit 514 on the device management server 50. However, only the part necessary for capacity estimation can be operated as a separate module, and the host computer 30 It may be configured to be operable.

As described above in the third embodiment, the data library system 10 has an expiration date on the recording medium. Therefore, if the capacity of the recording medium to be set at the time of system introduction is not properly estimated, the expiration date occurs without being used. The recording medium cannot be used up. Therefore, in the third embodiment, the capacity estimation means for preventing the expiration of the usage has been described.

After introducing the data library system 10, the system administrator grasps the expiration date for the free capacity (that is, the unused medium) of the system in order to prevent the expiration date in the process of operating the system. There is a need.

In this embodiment, a method for monitoring the expiration date information of unused media in the system on the device management server 50 after installation will be described.

FIG. 25 shows a configuration example of the capacity management unit 511 of the device management server 50.

The capacity management unit 511 includes a capacity acquisition unit 2501, a capacity storage unit 2502, a capacity monitoring unit 2503, an expiration date monitoring unit 2504, and a capacity addition schedule management unit 2505.

The capacity acquisition unit 2501 acquires the storage capacity from each device in the system managed by the device management server 50 via the management I / F unit 506 periodically / when necessary. In the case of the data library system 10, the management I / F unit 212 of the server 100 to the optical disc management table 2100, or the management I / F unit 108 of the portable recording device 103 to the recording medium storage table 700 or the portable recording device configuration management table. Get 800.

The capacity storage unit 2502 is a part that stores all or a part of the storage capacity of each device acquired by the capacity acquisition unit 2501, and is a part that manages the capacity management table 1500 described above. Not only the latest storage capacity information but also the past storage capacity information acquired from the start of system operation or the past storage capacity information for a certain period is retained, and the transition status of the storage capacity usage can be grasped.

The capacity monitoring unit 2503 monitors information (usage amount, free capacity) regarding the storage capacity of each device acquired by the capacity acquisition unit 2501. The user / administrator can use the user I / F unit 503 and the display device 102 to set a usage threshold for the storage capacity of each device, and the capacity monitoring unit 2503 refers to the threshold and uses each storage. Monitor whether the amount exceeds the threshold.

When the storage capacity acquired by the capacity acquisition unit 2501 is the data library system 10, the expiration date monitoring unit 2504 monitors whether or not the medium usage time limit of the unused medium has expired. The user / administrator can use the user I / F unit 503 and the display device 102 to set a threshold value for the remaining period until the medium usage period, and the usage period monitoring unit 2504 refers to the threshold value and uses the medium. You may monitor whether it has expired.

The capacity addition schedule management unit 2505 uses the capacity calculation execution unit 514 while referring to the monitoring results of the capacity monitoring unit 2503 and the expiration date monitoring unit 2504, or the storage capacity of each device is depleted or the medium usage period has expired. Predict when the free space will run out, and create / manage a capacity addition schedule. At that time, as described in the third embodiment, the regular maintenance scheduled for each device of the system of FIG. 1 by the maintenance plan creation / management unit 611 of the maintenance server 60 via the maintenance I / F unit 507. It is also possible to acquire a plan for (part replacement or periodic maintenance) and create a capacity addition schedule that matches the plan for regular maintenance as much as possible.

The user / system administrator can check the storage capacity of each device using the user I / F unit 503 of the device management server 50 and the display device 102.

FIG. 26 shows a screen example 2601 that displays the free capacity of the data library system 10 and the medium expiration date. In this screen example 2601, a resource list display screen 2602 is displayed on the left, and a resource detail display screen 2603 is displayed on the right.

The resource list display screen 2602 displays a list of all devices or only storage devices on the system of FIG. 1 managed by the capacity management unit 511 of the device management server 50.

The resource detail display screen 2603 displays detailed information when an arbitrary device is selected on the resource list display screen 2602.

For example, in FIG. 26, when a portable recording device of the data library system 10 is selected on the resource list display screen 2602 (portable recording device A in the figure), the capacity of the portable recording device is displayed on the resource detail display screen 2603. Display information in detail. This screen example shows that the used capacity of the portable recording apparatus A is 40% (400 TB) of the total capacity, and the unused capacity is 60% (600 TB) of the total capacity. Also, the breakdown of unused (free space) capacity, that is, the number and capacity of media that have already expired, and the number of media that are within a threshold (for example, 60 days remaining until the expiration date) for the remaining period until the expiration date of the medium. And the capacity, and the number and capacity of other media are displayed. Further, when it is desired to confirm details of each item, when a [Detail] button 2604 is designated, a detailed information screen 2605 is displayed.

On the detailed information screen 2605, the usage status of all recording media is displayed for each of one or more recording media storage units set in the portable recording device A. In this screen example, the recording medium 1 of the recording medium storage unit a is “used” indicating that data has been recorded, and the recording medium 2 is currently recording data and indicates that the expiration date is within a threshold. “In use / within threshold (60 days remaining)”, “Expiration date (date and time of expiration date)” indicating that the recording medium 3 is unused and the expiration date has expired, and the recording medium 4 is unused and has an expiration date “Within threshold (60 days remaining)” indicating that the recording medium 5 is within the threshold, and “more than threshold (60 days remaining)” indicating that the recording medium 5 is unused and the expiration date has not reached the threshold. In addition, the ratio of “expired”, “within threshold (60 days remaining)”, “threshold (60 days remaining) or more” is displayed.

Here, when an expiration occurs in the “in use” state as in the recording medium 3 described above, the state becomes “expired”, and subsequent additional recording is prohibited.

FIG. 27 shows a screen example 2701 different from FIG. 26 displaying the free space of the data library system 10 and the medium expiration date.

26 is greatly different from FIG. 26 in that the data library system 10 is displayed as one resource on the resource list display screen 2702 on the left. Then, on the resource detail screen 2603 on the right, the components included in the data library system 10 are displayed, and the respective storage capacities are displayed. In this screen example, the capacity information of the HDD 2 is displayed as the block storage 101, and the capacity of the portable recording device A is displayed as the portable recording device. When a [Detail] button 2704 displayed only on the portable recording apparatus A is instructed, a screen 2705 regarding the expiration date information of the unused medium is displayed. When a screen similar to the screen 2605 in FIG. 26 is displayed, the [Location] button 2706 is designated.

The capacity management unit 511 of the device management server 50 uses the display device 102 in response to an instruction from the user / administrator via the user I / F unit 503, and the planned consumption capacity and the capacity storage unit illustrated in the lower part of FIG. The transition state of the usage amount of the storage capacity stored in 2502 can be displayed. FIG. 28 is an example of a capacity transition screen that displays the planned consumption capacity created when the data library system 10 is introduced and the actual amount of use up to the present time.

The capacity transition screen 2801 displays the planned consumption capacity and the actual usage amount on the same graph, and also displays a message screen 2802 indicating whether the usage status is as planned. If the actual value is within a certain range from the planned consumption capacity, for example ± 3%, the usage is almost as planned. The actual value is less than the planned consumption capacity, for example, a range of -3% or more. In the case of, “Use amount is less than planned.” When the actual value is larger than the planned consumption capacity, for example, + 3% or more, “Use amount is larger than planned.” Is displayed.

As shown in this screen example, in the case of “Usage is less than planned.” 2803, there is a possibility that not all the recording medium can be consumed within the expiration date, so a warning message 2805 is displayed. In addition, the number / capacity of the recording media that may expire in the case of the current performance transition is displayed. On the other hand, in the case of “the amount of use is larger than planned.” 2804, a notice that a shortage of capacity occurs in the case of the current actual result transition is issued as in a warning message 2806.

When the expiration date monitoring unit 2504 in the capacity management unit 511 of the device management server 50 sets a threshold value for the remaining period until the expiration date of the recording medium and monitors the expiration date, when the threshold value approaches, the display device There is also a method of notifying the user / administrator by using 102 to display the warning message 2805 periodically or as necessary.

As described above, the user / system administrator can easily confirm and monitor the expiration date information of the unused medium of the system on the device management server 50 after the introduction.

In the fourth embodiment, after the data library system 10 is introduced, the user / administrator easily confirms the expiration date information of the unused medium on the device management server 50 in order to prevent the expiration date of the unused medium in advance. And provide a way to monitor. However, it is assumed that the expiration date may occur.

In this example, an operation method when an expiration occurs will be described.

When the expiration date monitoring unit 2504 of the device management server 50 detects that the unused media has expired, a warning message 2901 as shown on the screen 29 is displayed using the display device 102.

On the warning message 2901, the location information of the recording medium that has expired is displayed. In addition, a [Close] button 2902 for closing this message and a [Solution] button 2903 for displaying possible solutions for expiration are displayed.

When the [Solution] button 2903 is selected, a solution screen 2904 showing a solution that can be implemented by the user / administrator for expiration is displayed.

In this screen example, 6 solutions are displayed.

In the figure, 1) and 2) indicate that all or a part of the expired recording medium is ejected from the data library system, and the recording medium that is unused and has not expired from other recording medium storage units included in the same system. Select the required number of sheets and set it instead of the ejected recording medium. In this method, the capacity of the recording medium that has expired becomes unrecordable and the used capacity of the entire system increases. However, the data to be stored in the recording medium storage unit (for example, the user who uses each recording medium storage unit) Or when related data is stored in the same recording medium storage unit). Note that the expired recording medium can be ejected manually or moved to a recording medium storage unit dedicated for ejection. There is also a method of replenishing a new recording medium from a recording medium storage unit dedicated for replenishment instead of taking out an unused recording medium from the recording medium storage unit in the same system.

3) In the figure, in order to effectively use an expired recording medium, recording is performed using a redundant code having a strength higher than that of a redundant code used in a normal recording process.

FIG. 30 shows an outline of the recording procedure of the portable recording device 103 when this method is selected. The data recording / reproducing unit 110 of the portable recording device 103 includes an unused medium used for data recording from the recording medium storage table 700 managed by the storage unit 112 or the portable recording device configuration management table 800 managed by the state management unit 116. An expiration date is acquired (S3001), and it is determined whether the unused medium has expired (S3002). As a result, if the usage period has not expired, the redundant code used during normal recording is used (S3003), and data is recorded on the unused medium using the redundant code (S3005). On the other hand, if the unused medium has expired, a redundant code having a higher strength than the redundant code used during normal recording is used (S3004), and data is recorded on the unused medium using the redundant code. (S3005). Then, when recording is performed using a normal redundant code after the recording is completed, a verification process for verifying whether or not the recording data is correctly written is performed by a simple algorithm (for example, checking only an arbitrary recording part or calculating a hash value) (S3006). On the other hand, when the recording is performed on the expired recording medium, a verify process comparing all the recording data is executed (S3007). By using the above method, an expired recording medium can be used effectively.

4) 5) in the figure is different from the above 1) and 2) in that it is not a recording medium storage unit included in the same system but a recording medium storage unit included in another system that is unused and has not expired. Use the medium. As shown in FIG. 31, when the device management server 50 detects that there is an expired unused medium in the portable recording device 103 (1) of the data library system 10A, the device management server 50 sends a data library system 10A to the data library system 10A. It instructs the unused unused media to be discharged out of the system. In addition, the device management server 50 takes appropriate data in consideration of, for example, an unused medium that has sufficient storage capacity or an unused medium that is about to expire, among other systems than the data library system 10A. The library system 10B is extracted. Then, the apparatus management server 50 instructs the extracted data library system 10B to move the necessary number of unused media. The discharge and movement of the unused medium may be performed automatically by the recording medium transport unit 114 or may be performed via an operator. At this time, the device management server 50 displays the execution procedure and the execution status on the display device 102 for the user / administrator. By using the above method, it is possible to appropriately replenish the recording medium in the entire system shown in FIG. Since the recording medium is moved between the data library system 10A and the data library system 10B, each data library system 10 includes the recording medium storage table 700 and the portable recording apparatus configuration management table 800 of the portable recording apparatus 103. The system configuration management table 900 of the server 100 is updated. Similarly, the device management server 50 updates the capacity management table 1500 and the device configuration management table 1400.

Here, when the operator performs discharge and movement of the unused medium, in order to facilitate the operation, the state management / display unit 116 of the portable recording apparatus 103 to be discharged / moved is used to blink an LED or to display a dedicated message. Is displayed. There is also a method of automatically ejecting from the corresponding recording medium storage unit 111.

As described above, even when an unused medium expires, the expired medium can be used effectively by changing the recording method. In addition, archiving processing in the same data library system can be continued by diverting unused media that has not expired from another device instead of expired media.

In the fifth embodiment, the operation method in the case where the unused medium expires is described. However, in this embodiment, an operation method for efficiently consuming unused medium that is nearly expired will be described.

When the device management server 50 and / or the server 100 detects that there is an unused medium that is about to expire in the portable recording device in the data library system 10, it performs one of the following. The following items may be displayed on the display device 102 so that the user / administrator can select them.
(1) The device management server 50 acquires the policy management table 1100 from the archive management server 40, increases the value of the archive execution frequency 1106, and re-registers it with the archive management server 40. (Control of archive capacity by dynamic change of archive policy)
(2) The device management server 50 acquires the policy management table 1100 from the archive management server 40, updates the rule 1105 so that the capacity to archive increases, and re-registers with the archive management server 40. (Control of archive capacity by dynamic change of archive policy)
(3) When the apparatus management server 50 / server 100 detects a medium with a high degree of deterioration among the recorded mediums in the data library system 10, the apparatus management server 50 / server 100 uses an unused medium that is about to expire and has not used the medium that has deteriorated. Copy data to the media. (Used for migration of degraded media)
(4) When the device management server 50 / server 100 detects that the deleted data is scattered on the recorded medium, the unused medium that is about to expire is used to change the recorded medium to the unused medium. Only the data that has not been deleted is copied, and the recorded medium is discarded if necessary. (Used for migration of media with deleted data)
The above execution control may be performed in cooperation with the device management server 50 and the server 100.
