Step 1

Physically remove the volume from the storage device.

See Ejecting volumes.

Step 2

If the volume is in a robotic library, move it to stand alone.

See About moving volumes.

Step 3

Record the current number of mounts and expiration date for the volume.

See the values in the Media (Media and Device Management > Media in the NetBackup Administration Console).

Step 4

Delete the volume entry.

See Deleting a volume.

Step 5

Add a new volume entry.

See Adding volumes by using the Actions menu.

Because NetBackup sets the mount value to zero for new volume entries, you must adjust the value to account for previous mounts.

Set the maximum mounts to a value that is equal to or less than the following value:

The number of mounts that the manufacturer recommends minus the value that you recorded earlier.

Step 6

Physically add the volume to the storage device.

See Injecting volumes into robots.

Step 7

Configure the number of mounts

Set the number of mounts to the value you recorded earlier by using the following command:

On Windows hosts:

install_path\Volmgr\bin\vmchange -m media_id -n number_of_mounts

On UNIX hosts:

/usr/openv/volmgr/bin/vmchange -m media_id -n number_of_mounts

Step 8

Set the expiration date to the value you recorded earlier.

See Changing volume properties.
