#/************************* HORCM_DEV *************************************/
#
# The HORCM_DEV parameter is used to define the addresses of the physical
# volumes corresponding to the paired logical volume names. Each group
# name is a unique name used by the hosts which will access the volumes.
#
# The group and paired logical volume names defined here must be the same for
# all other (remote) hosts that will access this device group.
# The hardware SCSI bus, SCSI-ID, and LUNs for the device groups do not need
# to be the same on remote hosts.
#
# <dev_group>
# This parameter is used to define the device group name for paired logical
# volumes. The device group name is used by all Raid Manager commands for
# accessing these paired logical volumes.
# <dev_name>
# This parameter is used to define the names of the paired logical volumes
# in the device group.
# <port#>
# This parameter is used to define the XP256 port number used to access the
# physical volumes in the XP256 connected to the "dev_name". Consult your
# XP256 for valid Port numbers to specify here.
# <TargetID>
# This parameter is used to define the SCSI target ID of the physical
# volume on the port specified in "port#".
# <LUN#>
# This parameter is used to define the SCSI logical unit number (LUN) of
# the physical volume specified in "targetID".
