50 Volume Management for the XP10000/XP12000
Volume Count list
Specifies the number of LDEVs that should form a LUSE volume. For example, if you select 3 in the Volume
Count list, three LDEVs are expected to form a LUSE volume and then three LDEVs are added to the
Expanded LDEVs list. You can select an LDEV only from the Volume Count list. You cannot select a LUSE
volume.
Free LDEVs table
Lists the LDEVs, VSC volumes, and LUSE volumes that can constitute a LUSE volume in combination with the
LDEV selected as a top LDEV in the Select an LDEV list. The table contains the following information:
• LDEV: An LDEV status icon (Table 22), a CU number, and an LDEV number. If the selected LDEV is a
LUSE volume, the LDEV number of the top LDEV in the LUSE volume is displayed. An LDEV number that
ends with a # indicates that the LDEV is an external LU (for example, 00:01#).
NOTE: If an LDEV number ends with V (for example, 00:01V), the LDEV is a virtual volume
(V-VOL). For more information about V-VOLs, see the HP StorageWorks Snapshot XP User Guide.
• Capacity: Capacity of the LDEV represented in units (GB or MB), based on the capacity you indicate
with the Capacity Unit box.
• RAID: RAID level of the LDEV. The RAID level column contains a hyphen (-) when the LDEV is an external
LU or virtual volume (V-VOL).
• PG: A combination of the disk group and the parity group. If the LDEV extends over two or more parity
groups, the PG column displays the smaller parity group number. 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: If a parity group number starts with V (for example, V1-1), the parity group consists of one
or more virtual volumes (V-VOLs).
• CLPR: The cache logical partition (CLPR) number and name. The CLPR number consists of two digits.
The CLPR name consists of up to six characters. For detailed information about CLPRs, see the
HP StorageWorks XP Disk/Cache Partition User Guide.
• Selected LDEVs: The number of LDEVs selected in the Free LDEVs table
Expanded LDEVs list
Lists the LDEVs that are selected as LUSE volume components. An LDEV from the Free LDEVs table is added
to this list by clicking Add. The Expanded LDEVs list contains the following information:
• Selected LDEVs: Number of LDEVs selected in the Expanded LDEVs list
• Number of LDEVs: Number of LDEVs contained in a LUSE volume
• Capacity: The capacity of a LUSE volume. The number is displayed in GB or MB depending on the
selected capacity unit.
Buttons
• Add: Adds the selected LDEVs from the Free LDEVs table to the Expanded LDEVs list
• Delete: Removes the selected LDEVs from the Expanded LDEVs list and moves it back to the Free LDEVs
table
• Set: Creates a LUSE volume consisting of the volumes in the Expanded LDEVs list. The LDEVs that are
set as LUSE volume components are shown in blue in the LDEV Information table and the free LDEVs are
deleted from the table.
• Apply: Registers the LUSE settings with the disk array
• Cancel: Cancels the LUSE settings
