Considerations for managing tapes with partial catalog replication
The tapes from the production domain are not assigned in the disaster recovery domain. The tapes must be manually added to the database and placed in a pool where they cannot get accidentally overwritten. This can also be done using a combination of barcode rules and the robot inventory command.
As the tapes are not assigned on the disaster recovery primary server they will not be released to the global scratch pool when backups expire and therefore these tapes must be manually recycled.
Caution:
Care must be taken to ensure that the tapes are manually moved to the global scratch pool only when they do not have valid backups on them.
The simplest way of checking this is to create two lists by running the commands bpimagelist - d "01/01/1970 00:00:00" - media - l and vmquery - pn <private pool name> -b and then comparing the lists. Tapes found in the second list but not found in the first list have no valid images on them and can be moved to the scratch pool by running the command vmchange - p <scratch pool number> -m <media id>.
