PURGE Command
Description PURGE removes BIM-EPIC dataset definitions (EDDs), versions, and
tape volume serial numbers from the DSN Catalog. With PURGE, you
can delete an entire dataset and all associated versions (tape and disk) or
simply remove a tape volume and the associated versions.
Datasets which are part of a multi–dataset group cannot be purged until
all other datasets in the group are scratched or deleted. In addition, all
versions must be in closed status before they can be purged.
If an Automated Cartridge Library (ACL) is supported, PURGE sets the
tape volume to scratch status in the ACL inventory.
!
WARNING:
Do not use this command for routine deletion of datasets.
When a tape volume is purged, BIM-EPIC does not attempt to determine
whether it is a valid scratch tape. For this reason, use this command only
when a physical tape volume is destroyed or permanently removed from
your installation.
Encrypted dataset versions must not be purged from the DSN Catalog.
Once information about an encrypted version is deleted, it cannot be
decoded and is forever unreadable.
