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
.
