Managing tapes
Deleting a replication configuration
1. Right‐click on the primary virtual tape, and select Replication from the context
menu.
2. Select Remove from the following context menu.
This allows you to remove the replication configuration on the primary and either
delete or promote the replica resource on the target server at the same time.
Stop here.
Promoting a replica resource
If a primary virtual tape is damaged or corrupted, administrators can restore the
data by promoting the equivalent replica. After promotion, the virtual tape is
placed in the virtual vault on the former target server (now the primary). An
administrator can then:
move the virtual tape to a virtual library on the local server
replicate the virtual tape back to the original source server.
Once promoted, a replica resource cannot revert to being a replica resource. You
must create a new replication configuration for the new primary tape.
TIn order to maintain the integrity of restored data, the VTL software will not
promote an invalid replica resource, such as a replica that has been damaged or left
incomplete by a transmission fault. It will likewise refuse to promote a replica
resource while a replication is still in progress.
1. In the object tree of the VTL console, expand the VTL target server node, expand
the Virtual Tape Library System and Replica Resources nodes.
2. Under the Replica Resources node, right‐click on the replica that you want to
promote (
