• Volume Count drop-down box - Number of LDEVs that form a LUSE volume.
For example, if you select 3 in the Volume Count combo box, three LDEVs are expected to form a
LUSE volume, and then three LDEVs are added to the Expanded LDEVs list. Note: You can select
an LDEV only from the Volume Count drop-down box. You cannot select a LUSE volume.
• Expanded LDEVs list - LDEVs that are selected as LUSE volume components. An LDEV is added to
this list when the <<Add button is selected (see below).
• Selected LDEVs - Number of LDEVs selected in the Expanded LDEVs list.
• Number of LDEVs - Number of LDEVs displayed in the Expanded LDEVs list.
• Size - Total capacity of the LDEVs displayed in the Expanded LDEVs list, in either GB or MB.
• Free LDEVs table - LDEVs or LUSE volumes selected in the Select an LDEV drop-down box that
are eligible to become part of a LUSE volume.
Note: The drop-down lists on the upper-right of the Free LDEVs table 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.
• LDKC:CU:LDEV: LDEV status icon (see
Table 4 on page 18) and the LDKC, CU, and LDEV
numbers. If the selected LDEV is a LUSE volume, the LDEV number of the top LDEV in the
LUSE volume is displayed.
Note: An LDEV number that ends with a # indicates that the LDEV is an external volume
(for example, 00:00:01#). For details regarding external volumes, see HP StorageWorks
XP24000 External Storage Software User’s Guide.
Note: An LDEV number that ends with a letter V indicates that the LDEV is a virtual volume
(V-VOL) for XP Snapshot (for example, 00:00:01V). For details regarding V-VOLs, see HP
StorageWorks XP24000 Snapshot User’s Guide.
Note : An LDEV number that ends with a letter X indicates that the LDEV is a virtual volume
(V-VOL) for XP Thin Provisioning (for example, 00:00:01 X). For details regarding V-VOLs, see
HP StorageWorks XP24000 Thin Provisioning Software User’s Guide.
• RAID : RAID level of the LDEV.
Note: The RAID level is left unspecified with a hyphen (-) when the LDEV is an external LU
or virtual volume (V-VOL).
• PG: Parity group. If the LDEV extends over two or more parity groups, the PG column displays
the smaller parity group number.
Note: A parity group number that starts with a letter E indicates that the parity group consists
of one or more external LUs (for example, E1-1).
Note: A parity group number that starts with a letter V indicates that the parity group consists
of one or more virtual volumes (V-VOLs). (for example, V1-1).
• CLPR: The CLPR number. For detailed information about CLPRs (cache logical partitions), see
HP StorageWorks XP24000 Disk/Cache Partition User’s Guide.

• Delete>> - Moves a selected LDEV from the Expanded LDEVs list to the Free LDEVs list.
• Set - Creates a LUSE volume consisting of the volumes currently in the Expanded LDEVs list. The
new LUSE is displayed in blue bold italics in the LDEV Detail table (on the upper-right corner of the
LUN Expansion tab), but is not actually created until you click the Apply button.
