Changing LUSE capacities
• Expanding LUSE capacities
To expand the capacity of a LUSE volume, select the LUSE volume you want to expand, and then add
LDEVs or LUSE volumes, or first select the LDEVs or LUSE volumes you want to add, and then select a
LUSE volume to be expanded. For more information, see ”Creating a LUSE volume using the Volume
Count list” on page 51, ”Creating a LUSE volume using the Select an LDEV list” on page 52, or
”Creating a LUSE volume using the LDEV information table” on page 52.
Each LDEV or LUSE volume that you want to add must have the same capacity as each LDEV in a LUSE
volume to be expanded.
• Reducing LUSE capacities
You may not reduce the capacity of an existing LUSE volume. If you want a LUSE volume to have a
smaller capacity, you must release and then redefine the LUSE volume.
Resetting an unregistered LUSE volume
When you create a LUSE volume, the screen shows the changes in blue bold italics until you register the
volume into the disk array by clicking Apply. The LUSE volume in blue bold italics indicates that you can
reset this LUSE volume to the state before it was created.
If the XP disk array has firmware version 21.06.22 or later installed, you can reset an unregistered LUSE
volume to the state before it was created. However, you cannot recover any LUSE volumes that have been
released already to the state when they were created. If the LUSE volume that you have created consists of
any LDEVs (those in blue bold italics) that have once been released from a different LUSE volume, you can
only reset your LUSE volume to the state when the constituting LDEVs were released from the other LUSE
volume.
1. In the Volume Management pane, select the CU number from which you want to reset an unregistered
LUSE volume. The LDEV Information table shows all LDEVs that the selected CU contains.
2. In the LDEV Information table, right-click an unregistered LUSE volume (displayed in blue bold italics)
and select Reset Selected Volume. A confirmation message appears.
3. Verify the information in the dialog box and click OK. The unregistered LUSE volume will be reset to the
state before this LUSE volume was created. The LDEV Information table displays the LUSE volumes or the
LDEVs constituting the selected LUSE volume that has just been reset.
