After recovering the partition, you must add tape drives and a robot to the partition, and

For example, if the partition contains SDLT600 tape cartridges, you will only be able to
select DLT-S4 tape drives when mapping devices to the recovered partition.
When a VTL partition is recovered on a target system, a new serial number is
created for the partition.

target system, after you failback the partition, you must remap your backup
application again to point to the source system.
