IBM Tivoli Storage Manager, Version 7.1

Deleting storage pool volumes that contain data

To prevent accidental deletion of backed-up, archived, or space-managed files, the server does not allow you to delete a volume that contains user data unless you specify DISCARDDATA=YES on the DELETE VOLUME command. After all files have been deleted from the volume, the server deletes the volume from the storage pool.

About this task

Tips:

The Tivoli® Storage Manager server will not delete archive files that are on deletion hold.
If archive retention protection is enabled, the Tivoli Storage Manager server will delete only archive files whose retention period has expired.
Volumes in a shred pool (DISK pools only) are note deleted until the data on it is shredded. See Securing sensitive client data for more information.

For example, to discard all data from volume WREN03 and delete the volume from its storage pool, enter:

delete volume wren03 discarddata=yes

The server generates a background process and deletes data in a series of batch database transactions. After all files have been deleted from the volume, the server deletes the volume from the storage pool. If the volume deletion process is canceled or if a system failure occurs, the volume might still contain data. Reissue the DELETE VOLUME command and explicitly request the server to discard the remaining files on the volume.

To delete a volume but not the files it contains, move the files to another volume. See Moving data from one volume to another volume for information about moving data from one volume to another volume.

Residual data: Even after you move data, residual data may remain on the volume because of I/O errors or because of files that were previously marked as damaged. (Tivoli Storage Manager does not move files that are marked as damaged.) To delete any volume that contains residual data that cannot be moved, you must explicitly specify that files should be discarded from the volume.
