154 Volume Manager operations

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” on page 151.

• 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” on page 153), and

redefine the LUSE volume (see ”Creating LUSE volumes” on page 151).

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.

3. Click OK.

The setting of the selected LUSE volume that is not registered yet is reset to the state it was in before this

LUSE volume was created, and the LUSE volumes or LDEVs constituting the selected LUSE volume that

has just been reset appear in the LDEV Information table.
