Changing LUSE Capacities
There are two ways to change the capacity of a LUSE volume:
• Expanding LUSE capacities
To expand the capacity of a LUSE volume, select the LUSE volume that you want to expand,
and then add LDEVs or LUSE volumes; or first select LDEVs or LUSE volumes that you want
to add, and then select a LUSE volume to be expanded. For further information, see
“ Creating a LUSE Volume ” on page 22.
• Reducing LUSE capacities
You cannot reduce the capacity of an existing LUSE volume. If you want a LUSE
volume to have a smaller capacity, you must first release the LUSE volume (see
“ Releasing a LUSE Volume ” on page 27), and then redefine the LUSE volume (see
“ Creating a LUSE Volume ” on page 22).
Displaying a List of Volumes Combined into a LUSE Volume
A LUSE volume is a combination of multiple volumes (LDEVs). To display a list of volumes that are
combined into one LUSE volume, follow the procedure below:
1. Make sure that Remote Web Console is in Modify mode.
For detailed information about Modify mode, see the HP StorageWorks XP24000 Remote
Web Console User's Guide.
2. Select a LUSE volume in the LDEV Detail table (in the upper-right corner of the LUN Expansion
tab). Right-click a LUSE volume to display a pop-up menu.
3. Select LUSE Detail from the pop-up menu.
The LUSE Detail dialog box ( Figure 7 on page 29) displays a list of volumes (LDEVs) combined
into the LUSE volume. After viewing this list, click Close to close the dialog box.
