HP XP P9500 Storage - Manual (Page 28)

NOTE: To enable dual pathing of the command device under Solaris systems, make sure to
include all paths to the command device on a single line in the HORCM_CMD section of the config
file. Putting the path information on separate lines may cause parsing issues, and failover may not
occur unless the HORCM startup script is restarted on the Solaris system.
When a server is connected to two or more storage systems, the HORCM identifies each storage
system using the unit ID (see
Figure 13 (page 28) ). The unit ID is assigned sequentially in the order
described in this section of the configuration definition file. When the storage system is shared by
two or more servers, each server must be able to verify that the unit ID is the same Serial# (Seq#)
among servers. This can be verified using the raidqry command.

dev_name for Windows
In Windows SAN environment, "Volume{guid}" will be changed on every re-boot under
MSCS/Windows2k3, if Windows finds the same signature on the command device connected
with Multi-Path.Therefore, find NEW "Volume{guid}", and change "Volume{guid}" described in
the RAID Manager configuration file. Thus, RAID Manager supports the following naming format
specifying Serial#/LDEV#/Port# as notation of the command device for only Windows.
\\.\CMD-Ser#-ldev#-Port#
HORCM_CMD
#dev_name dev_name dev_name
\\.\CMD-30095-250-CL1-A
