dev_name for Windows
In Windows SAN environment,” Volume{guid}” is changed on every re-boot under
MSCS/Windows 2003/2008, if Windows finds the same signature on the command device
connected with Multi-Path. Therefore, the user must find NEW “Volume{guid}” and change
“Volume{guid}” described in the CCI configuration file. CCI 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

define the serial number, ldev#, port and host group for the CMDDEV.
