Data can be restored from the replica volume to the original volume if a volume pair has been defined with bi-directional copying by using swsrpsetvol (Replication volume information setting command).
Restoration can be executed according to the following procedures:
Execute swsrpcancel (Replication cancellation command) when the target volume for restoration has an EC session.
Execute swsrpmake (Replication creation command). The specification of an original volume and the replica volume is reversed at the time that the replication is executed. For the backup operation that uses QuickOPC/SnapOPC/SnapOPC+, execute swsrpmake (Replication creation command) without specifying the -T, -C and -P option.
Note
It is not possible to perform restoration using replication if the ETERNUS Disk storage system does not support SnapOPC+ restoration. If restoration is required, copy the data from the copy destination volume manually.
