Purging Disks or Disk Groups

When storage arrays are decommissioned either due to lease expiration or upgrade, the keys associated with the disks can be purged. Purging keys can be done either at the disk level or at the disk group level. By deleting an active disk group, all the keys are archived. By deleting an archived disk group, all the keys are purged.

Caution Purging the key is an unrecoverable operation. Unless there are exported backups of the key database, the key that is purged cannot be retrieved forever.
