To delete a storage unit from a NetBackup configuration means to delete the label that NetBackup associates with the physical storage.
To delete a storage unit does not prevent files from being restored that were written to that storage unit, provided that the storage was not physically removed and the backup image has not expired.
To delete a BasicDisk or Media Manager storage unit
Use the Catalog utility to expire any images that exist on the storage unit. This removes the image from the NetBackup catalog.
NetBackup automatically deletes any image fragments from a disk storage unit or a disk pool. This generally occurs within seconds of expiring an image. However, to make sure that all of the fragments are deleted, check the directory on the storage unit to make sure that it is empty.
In the Details pane, select the storage unit you want to delete. Hold down the Control or Shift key to select multiple storage units.
In the confirmation dialog box, select the storage units to delete.
Modify any policy that uses a deleted storage unit to use another storage unit.
If a storage unit points to disk pool, the storage unit can be deleted without impacting the disk pool.
