The RAID storage systems (9900V and later) manage the LUN configuration on a port through the LUN security as shown in the following figure.
CCI uses absolute LUNs to scan a port, whereas the LUNs on a group are mapped to the host system so that the TID and LUN indicated by the raidscan command are different from the TID and LUN displayed by the host system. In this case, the TID and LUN indicated by the raidscan command should be used.
In the following example, you must start HORCM without a description for HORCM_DEV and HORCM_INST because the TID and LUN are not known. Use the port, TID, and LUN displayed by the raidscan -find or raidscan -find conf command for HORCM_DEV (see the example for displaying the port, TID, and LUN using raidscan).
For details about LUN discovery based on a host group, see Host Group Control in the Command Control Interface User and Reference Guide.
Displaying the port, TID, and LUN using raidscan
# ls /dev/rdsk/* | raidscan -find DEVICE_FILE UID S/F PORT TARG LUN SERIAL LDEV PRODUCT_ID /dev/rdsk/c0t0d4 0 S CL1-M 0 4 31168 216 OPEN-3-CVS-CM /dev/rdsk/c0t0d1 0 S CL1-M 0 1 31168 117 OPEN-3-CVS /dev/rdsk/c1t0d1 - - CL1-M - - 31170 121 OPEN-3-CVS
UID: Displays the UnitID for multiple RAID configuration. A hyphen (-) is displayed when the command device for HORCM_CMD is not found.
S/F: S indicates that the port is SCSI, and F indicates that the port is Fibre Channel.
PORT: Displays the RAID storage system port number
TARG: Displays the target ID (converted by the fibre conversion table)
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.
