Deleting Volumes from the ISM Catalog

Removing a volume means that ISM no longer tracks the volume in the ISM catalog and effectively releases the volume from the control of ISM. Remove a volume from the ISM catalog only if you will never need the data on the volume again or if the volume has been physically damaged and is unusable.

You rarely need to remove a volume from the ISM catalog. ISM catalog entries take up a small amount of disk space. Leave the volume in the ISM catalog so that you do not accidentally label another volume with the same name.

If a volume is lost or destroyed, remove its entry from the ISM catalog. Otherwise, ISM might request the volume to recover data.

To delete a storage volume from the ISM catalog

Remove the storage device as follows:
```
ism_rm -volume name
```
To verify that the storage volume was deleted, issue the command:
```
ism_show -volumes
```
The ISM server no longer tracks the storage volume and its associated save sets.

Important:

If you accidentally delete a volume from the ISM catalog, you can still recover the data with the ism_catalog -recreate_from command as long as you have not overwritten the volume with new data.
