Emulation: The emulation type of the LDEV. If the selected LDEV is a CVS 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 ”

LUSE

operations that handle a path-defined LDEV

” on page 54.

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, CVS 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, CVS 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#).

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.
