Data failback

Failing back a virtual tape library
If a virtual tape library or NAS share has been destroyed or corrupted
on the original source system, the data failback option copies the
replicated virtual tape library or share from the target system to the
source system. Once the replicated virtual tape library or share is
copied to the source system, it can be recovered on the source system
and returned to normal operation.

1. Access the remote management pages on the target system.
2. On the Replication page, click Target Role.
