An LDEV number ending with # (for example,
00:00:01#) indicates that the LDEV is an external
volume. For details about external volumes, see the HP
StorageWorks XP24000/XP20000 External Storage

An LDEV number ending with V (for example, 00:00:01
V) indicates that the LDEV is a virtual volume (V-VOL)
for XP Snapshot. For details about V-VOLs, see the HP
StorageWorks XP24000/XP20000 Snapshot User
Guide.
LDKC:CU:LDEV
Emulation type. If the selected LDEV is a LUSE volume, the
