Releasing LUSE volumes
CAUTION:
Releasing LUSE volumes is a destructive operation. Move and/or back up data before proceeding.
Delete all SCSI paths to the LUSE volume you want released.
1. In the Volume Manager pane, select the CU number from the LDEV Information tree. The LDEV
Information table displays all LDEVs in the selected CU.
2. In the LDEV Information table, right-click a LUSE volume, and select Release LUSE Volume. The
Release LUSE Confirmation pane appears.
3. Verify that the LUSE volumes listed in the confirmation pane are the ones you want released.
4. Click OK (or Cancel).
NOTE:
New settings appear on the Volume Manager pane in blue bold italics, but are not yet
implemented.
5. Click Apply (or Cancel).
6. Click OK (or Cancel).
Changing LUSE capacities
There are two ways to change a LUSE volume's capacity:
• Expanding LUSE capacities
To expand a LUSE volume's capacity, select the LUSE volume you want to expand, and add LDEVs or
LUSE volumes; or first select the LDEVs or LUSE volumes you want to add, and select a LUSE volume to
be expanded. For more information, see Creating LUSE volumes .
• Reducing LUSE capacities
You cannot reduce an existing LUSE volume's capacity. If you want a LUSE volume to have a smaller
capacity, you must first release the LUSE volume (see Releasing LUSE volumes ), and redefine the LUSE
volume (see Creating LUSE volumes ).
Resetting unregistered LUSE volumes
When you create a LUSE volume, it remains highlighted in blue bold italics until you register it into the
array by clicking Apply. A LUSE volume in blue bold italics indicates you can reset this LUSE volume to
the state it was in before it was created.
NOTE:
You can use this function to reset an unregistered LUSE volume to the state it was in before it was created.
However, you cannot recover LUSE volumes that have already been released to the state they were in
when they were created. Therefore, if the LUSE volume you created consists of any LDEVs (those in blue
bold italics) that have been released from a different LUSE volume, you can only reset the LUSE volume to
the state it was in when the constituting LDEVs were released from the other LUSE volume.
1. In the Volume Manager pane, select a CU number from the LDEV Information tree. The LDEV
Information table displays all LDEVs in the selected CU.
2. In the LDEV Information table, right-click an unregistered LUSE volume (in blue bold italics), and
select Reset Selected Volume. The Reset LUSE Confirmation pane appears.
