The selected top volume appears in the Expanded LDEVs list. Normal LDEVs and LUSE volumes
that can be used for a LUSE volume are displayed in the Free LDEVs list.
Note: The drop-down lists in the upper-right of the Free LDEVs list enable you to narrow entries
in this table. If you select an LDKC and a CU from the LDKC and CU drop-down lists, the Free
LDEVs table displays only the LDEVs belonging to the selected LDKC and CU.
4. Select the number of LDEVs needed to form a LUSE volume from the Volume Count box.
The Expanded LDEVs list displays as many LDEVs as specified in the Volume Count box. For
example, if 3 is specified in Volume Count, three LDEVs appear in Expanded LDEVs. Note: You
cannot select LUSE volumes from the Volume Count box. To select LUSE volumes, select LDEVs
from Free LDEVs, and click <<Add.

list, and then click Delete>>.

A dialog box is displayed. If the displayed dialog box asks if you want
to perform a LUSE operation on a volume that has a path definition (see
“ LUSE Operations Using a Path-defined LDEV ” on page 13 for the details on this operation),
follow step a below. If the displayed dialog box is the Set LUSE Confirmation dialog box (see
“ Creating a LUSE Volume from the LDEV Detail Table ” on page 22), follow step b below.
a. If the displayed dialog box asks if you want to perform a LUSE operation on a volume that
has a path definition, click OK. A message appears and informs you that the specified
volumes will be expanded to a LUSE volume. Next, go to step 6 .
To cancel the LUSE operation, click Cancel. The screen will return to the previous dialog
box, and then you can retry the operation.
b. If the displayed dialog box is the Set LUSE Confirmation dialog box, go to step 6 .
6. To create the LUSE, click OK. The selected top LDEV is displayed (in blue bold italics ) as a
LUSE volume in the LDEV list.
Note : The LUSE volumes that have been created but are not yet registered to the storage system
(those in blue bold italics ) can be reset to the state they were in before they were created (see
“ Resetting an Unregistered LUSE Volume ” on page 25).
7. Click Apply.
8. Click OK (or Cancel).
The setting for this LUSE operation is registered for the storage system.
Resetting an Unregistered LUSE Volume
When you create a LUSE volume, it will remain highlighted in blue bold italics until you register it to the
storage system by clicking Apply. A LUSE volume in blue bold italics indicates that you can reset this
LUSE volume to the state it was in before it was created.
Note : This is a function that allows you to reset an unregistered LUSE volume to the state it was in before
it was created. However, it does not allow you to recover any LUSE volumes that have been released
already to the state they were in before they were created. Therefore, if the LUSE volume that you have
created consists of any LDEVs (those in blue bold italics ) that have previously been released from a
different LUSE volume, your LUSE volume can only be reset to the state it was in when the constituting
LDEVs were released from that different LUSE volume.
The procedure to put the unregistered LUSE volume back to the state it was in before it was created
by using this reset function is described below.
1. Make sure that Remote Web Console is in Modify mode.
