Figure 10 LUN Configuration
RAID Manager uses absolute LUNs to scan a port, whereas the LUNs on a group are mapped for
the host system so that the target ID & LUN, which is indicated by the raidscan command, is different
from the target ID & LUN shown by the host system. In this case, the target ID & LUN indicated by
the raidscan command should be used.
In this case, you must start HORCM without a description for HORCM_DEV and HORCM_INST
because target ID & LUN are unknown. Use the port, target ID, and LUN displayed by the raidscan
-find or raidscan -find conf command for HORCM_DEV (see
Example 8 “Displaying the Port, TID,
and LUN Using raidscan” ).
For details on LUN discovery based on a host group, see Host Group Control in the HP XP7 RAID
Manager User Guide.

UID: displays the UnitID for multiple RAID configuration. If UID appears as '-' then the command
device for HORCM_CMD is not found.
S/F: displays that a PORT is SCSI or fibre.
PORT: displays the RAID storage system port number.
TARG: displays the target ID (converted by the fibre conversion table, see
“Fibre address conversion
tables” (page 55) ).
LUN: displays the Logical Unit Number (converted by the fibre conversion table).
SERIAL: displays the production number (serial#) of the RAID storage system.
LDEV: displays the LDEV# within the RAID storage system.
PRODUCT_ID: displays product-id field in the STD inquiry page.
