144 Volume Manager operations

The LDEV Information table displays detailed information for all open-system LDEVs in the selected CU. If

you select a normal LDEV, the information in this table is for the top LDEV. If you select a LUSE volume, the

information in this table is for all LDEVs in the LUSE volume. The table displays the following information:

LDEV: LDEV status icon (

Table 32

) and the CU and LDEV numbers. If the selected LDEV is a LUSE

volume, the LDEV number of the top LDEV in the LUSE volume appears.

NOTE:

If an LDEV number ends with # (for example, 00:01#), the LDEV is an external LU. For

more information about external LUs, see the HP StorageWorks External Storage XP user guide.

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.

Emulation: Emulation type. If the selected LDEV is a LUSE volume, the emulation type appears with an

asterisk and the number of volumes in the LUSE volume (for example, OPEN-E*5). If the selected LDEV

is a CVS volume, the emulation type appears with CVS (for example, OPEN-3 CVS).

Capacity: LDEV capacity in either MB or GB, depending on the unit selected in the Capacity Unit box.

RAID: LDEV’s RAID level.

NOTE:

The RAID level is left unspecified with a hyphen (-) when the LDEV is an external LU or

virtual volume (V-VOL).

PG: Combination of the disk group and parity group. If the LDEV extends over two or more parity

groups, the smaller parity group number appears.

NOTE:

If a parity group number starts with E (for example, E1-1), the parity group consists of one

or more external LUs.

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).

Paths: Number of paths 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 (see ”

Volume Manager operations using a

path-defined LDEV

” on page 129).

Access Attribute: Access attribute set for the LDEV.

IO Suppression Mode: Displays Disable when I/O requests from hosts are suppressed, or Enable if

I/O requests from hosts are not suppressed.

Cache Mode: Displays Disable when cache is set to be unused for responding to I/O requests from

hosts, or Enable when cache is set to be used for responding to I/O requests from hosts.

Ex-Dev Info.: Displays the LDEV’s drive type. Displays an asterisk (*) when the drive type is SATA.

Displays nothing when the drive type is not SATA.

CLPR: ID of the cache logical partition (CLPR) to which the displayed volumes belong. The CLPR ID is

composed of a CLPR number (two-digit) and a CLPR name (maximum of 16 characters)
