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 62, ” Creating a LUSE volume using the Select an LDEV list ” on page 63, or
” Creating a LUSE volume using the LDEV information table ” on page 64.
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.
