When the ETERNUS tape library unit used at the operation site is different to the one used at the disaster recovery site, the method of managing volume names may also be different. Therefore, check the integrity of backup tapes for each case. Refer to the "Table 14.4 Differences in volume names between tape library units", and check if the methods of managing volume names between the operation site and the disaster recovery site are the same.
Group A | Group B |
|---|---|
ETERNUS LT20 | ETERNUS LT130 |
Check the integrity of backup tapes using the procedures described in "The volume name management method is the same as the operation site" when units from the same group are used at both the operation and disaster recovery site.
Check integrity of backup tapes using the procedures described in "The volume name management method is different from the operation site" when units of different groups are used at each site.
The volume name management method is the same as the operation site
Load the backup tapes transported as described in "14.6 Actions in case of a Disaster" of "Transporting to the disaster recovery site" into the ETERNUS tape library unit.
Check the integrity of the tapes by executing the commands below. The command must be executed on the TSM server at the command prompt.
When executing these commands TSM tape storage information is read and displayed to show inconsistencies.
TSM: TSM_SERVER > audit library <library name> checklabel=barcode TSM: TSM_SERVER > checkin libvolume <library name> search=yes status=private checklabel=barcode |
Library name
Specify the library name.
Example:
Library name: LT130-B
TSM: TSM_SERVER > audit library LT130-B checklabel=barcode TSM: TSM_SERVER > checkin libvolume LT130-B search=yes status=private checklabel=barcode |
The volume name management method is different from the operation site
Load the backup tapes transported as described in "14.6 Actions in case of a Disaster of "Transporting to the disaster recovery site" via the Checkin/Checkout port of the ETERNUS tape library unit.
Check the integrity of the tapes by executing the commands below. The commands must be executed on the TSM server at the command prompt.
This method of checking tape integrity checks volume labels therefore it will take some time to complete.
The checkin libvolume command is started using background processes, therefore, the operation status must be checked using the query process command.
Time is needed to wait for the loading of the tape immediately after executing the checkin libvolume command. Therefore, specify the request ID and execute the REPLY command.
TSM: TSM_SERVER > audit library <library name> checklabel=barcode TSM: TSM_SERVER > checkin libvolume <library name> search=bulk status=private checklabel=yes TSM: TSM_SERVER > |
Library name
Specify the library name.
Example:
Library name: LT160-A
TSM: TSM_SERVER > audit library LT160-A checklabel=barcode TSM: TSM_SERVER > checkin libvolume LT160-A search=bulk status=private checklabel=yes TSM: TSM_SERVER > query process : TSM: TSM_SERVER > reply 005 ANR8499I Command accepted. |
