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 configuration 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. The replication creation command is executed without specifying the "-T" option, the "-C" option and the "-P" option of the backup operation that uses QuickOPC/SnapOPC/SnapOPC+.
Note
It is not possible to perform restoration using replication if the ETERNUS disk storage systems do not support SnapOPC+ restoration. If restoration is required, copy the data from the copy destination volume manually.
