Select An Ldev List - HP StorageWorks XP128 User Manual

• Emulation: The emulation type of the LDEV. If the selected LDEV is a VSC volume, the emulation type is
displayed together with CVS (for example, OPEN-3 CVS). If the selected LDEV is a LUSE volume, the
emulation type is displayed with an asterisk and the number of volumes in the LUSE volume (for
example, OPEN-E*5). If the LDEVs that comprise a LUSE volume extend over two or more VDEVs, the
emulation type is not displayed with an asterisk and the number of volumes (*n), and each LDEV in the
LUSE volume is displayed.
• Capacity: The capacity of the LDEV in either MB or GV, depending on which unit you selected in the
Capacity Unit box.
• RAID: The RAID level of the LDEV. The RAID level column contains a hyphen (-) when the LDEV is an
external LU.
• PG: A combination of a disk group and a 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).
• Paths: The number of paths that is set for the LDEV. If this column displays the number of paths for an
LDEV, you can use the LDEV as the top LDEV of a LUSE volume. For more information, see
operations that handle a path-defined
• Access Attribute: The access attribute that is set for the LDEV
IO Suppression: Displays Disable when the I/O request from the host is suppressed, or Enable if the
•
I/O request from the host is not suppressed
• Cache mode: Displays Disable when the cache is not set to be used for responding to the I/O request
from the host, or Enable when the cache is set to be used for responding to the I/O request from the
host
• Ex-Dev Info.: Displays the drive type of the LDEV. Displays an asterisk (*) when the drive type is SATA.
Nothing is displayed when the drive type is not SATA.
• CLPR: The ID of the CLPR (cache logical partition) to which the displayed volumes belong. The CLPR ID
is a CLPR number (two-digit) and a CLPR name (16 characters maximum)
• Selected LDEVs: The number of LDEVs selected in the LDEV Information table
• Capacity Unit button: Select a capacity unit (GB or MB) to describe LDEVs

Select an LDEV list

Displays the LDEVs, VSC volumes, and LUSE volumes of the selected CU that are eligible to become part of
a LUSE volume. The selected LDEV number becomes the top LDEV number of a LUSE volume.
NOTE: On an XP128 array, a selected LDEV in the Information Tree does not appear in the Select an
LDEV list.
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
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#).
• 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.
