Data saved on tapes as shown in Item 1 of 14.5.2 Tasks after ACM backup operation must be restored to local disks on the tape server at the disaster recovery site.
Check whether the tape media to which ACM management information was collected before restoration is in the available status. The status of tape media can be checked using the QUERY VOLUME command. If the status is unavailable, change it to available.
For details of the QUERY VOLUME command, refer to the explanation in the "ETERNUS SF TSM Administrator's Handbook".
TSM: TSM_SERVER > query volume <Volume name> format=detail |
Volume name
Specify the volume name to be checked.
Example:
Volume name: CJR019
TSM: TSM_SERVER > query volume CJR019 format=detail
Volume Name: CJR019
Storage Pool Name: FILE_SPOOL
Device Class Name: LT270DEV
Estimated Capacity: 762,938.0
Scaled Capacity Applied:
Pct Util: 0.0
Volume Status: Filling
Access: Unavailable <- Check here
Pct. Reclaimable Space: 0.0
Scratch Volume?: No
In Error State?: No
:
TSM: TSM_SERVER > |
Access: If the status is Unavailable, execute the UPDATE VOLUME command, and change the status to available.
For details of the UPDATE VOLUME command, refer to the explanation in the "ETERNUS SF TSM Administrator's Handbook".
TSM: TSM_SERVER > update volume <Volume name> access=<access status> |
Volume name
Specify the volume name to be changed.
Access status
Specify access permissions for the files stored under the volume name.
readwrite: Files can be read and written to.
readonly: Files can be read only.
unavailable: Files cannot be accessed.
destoryed: Files cannot be accessed due to damage to the volume.
offsite: The volume is at an offsite location where it cannot be mounted.
Example:
Volume name: CJR019
Access status: readwrite
TSM: TSM_SERVER > update volume CJR019 access=readwrite ANR2207I Volume CJR019 updated. TSM: TSM_SERVER > |
Restore ACM management information data.
For details of the dsmc restore command, refer to the explanation in the "ETERNUS SF TSM Backup/Archive Client Installation and User Guide".
# cd /opt/tivoli/tsm/client/ba/bin # ./dsmc restore <restore target> <restore destination> -virtualnodename=<node name> -password=<password> -subdir=yes |
Restore target
Specify the path name used when the backup was processed.
Ensure "/" is added at the end of the path name.
Restore destination
Specify the destination to which the backed up data is to be restored.
Node name/password
Specify the node name and password for the node for disaster countermeasure restoration specified at the time of backup
Example
Storage directory path for ACM management information at the operation site: /var/ACMBkupData/sftk-ssm2/
Directory path for data restoration destination local disk: /var/tmp/
Name of the node for disaster countermeasure restoration: TAPESERVER_FILE_NODE
Password: filenode
# cd /opt/tivoli/tsm/client/ba/bin # ./dsmc restore /var/ACMBkupData/sftk-ssm2/ /var/tmp/ -virtualnodename=TAPESERVER_FILE_NODE -password=filenode -subdir=yes |
You must expand archive files restored to the local disk of the data restoration destination as described in "14.8.2.1 Restoring ACM management information".
The following files must be expanded.
/data restoration destination directory/Tapesvr/TapeData/acm_tape_backup.tar
Data restoration destination directory
The data restoration destination directory refers the directory specified as the restoration destination as described in 14.8.2.1 Restoring ACM management information.
Tapesvr
Tapesvr refers to the name of the tape server where ACM management information is collected.
Example: The following files will be restored when following the example described in 14.8.2.1 Restoring ACM management information.
/var/tmp/sftk-ssm2/TapeData/acm_tape_backup.tar
The following directories are expanded by acm_tape_backup.tar.
FJSVswstm/data/Tapesvr/TboFiles/etc/opt/FJSVswstm/data/ctrl/ FJSVswstm/data/Tapesvr/TboFiles/etc/opt/FJSVswstm/conf/ FJSVswstm/data/Tapesvr/TboFiles/etc/opt/FJSVswstm/log/ FJSVswstm/data/Tapesvr/TSMBackupDir/ |
