If the replication operation was used to copy data from a system volume (LU) to a slice, then the backup operation was used to backup the data from the slice to a tape, this data can be restored directly from tape to the system volume (LU) by specifying the parameters that restore the data to a different Storage Server volume.
Figure C.11 Restoring from tape to system volume (LU)
The restoration procedure for data managed on tape is as follows:
Stop the restoration target server.
From the Tape Server, execute the tborestore command to restore data from tape to the system volume (LU) of the restoration target server.
If generation management used
# /opt/FJSVswstm/bin/tborestore -h SBK-SV [-g relative generation number | -v absolute generation number] -r sys_dv -d TRG-SV copy_dv |
If day management used
# /opt/FJSVswstm/bin/tborestore -h SBK-SV -t backup day and time -r sys_dv -d TRG-SV copy_dv |
Activate the restoration target server and resume transactions.
Note
If the restoration destination volume is changed when restoring from tape
If the restoration destination volume is changed when restoring data, take measures to ensure that restoration with a LU (disk) specified as the restoration destination volume, and restoration with a slice included in that LU (disk) specified as the restoration volume, cannot be performed simultaneously. If both are performed simultaneously, the restoration will not be correct because multiple restorations are performed to the same area.
