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 (
) 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 ”
