If a HINT is already specified, ":HINT" can be omitted for next command devices, and then a
command device is found from the cached Inquiry information of HORCM for saving unnecessary
device scanning.
HORCM_CMD
#dev_name dev_name dev_name
\\.\CMD-30095-250-CL1:/dev/rdsk/
\\.\CMD-30095-250-CL2
Example for minimum specification. Specifies to use any command device for Serial#30095:
\\.\CMD-30095:/dev/rdsk/
Example for under Multi Path Driver. Specifies to use any port as the command device for
Serial#30095, LDEV#250:
\\.\CMD-30095-250:/dev/rdsk/
Example for full specification. Specifies the command device for Serial#30095, LDEV#250
connected to Port CL1-A, Host group#1:
\\.\CMD-30095-250-CL1-A-1:/dev/rdsk/
Other examples:
\\.\CMD-30095-250-CL1:/dev/rdsk/ \\.\CMD-30095-250-CL2

(3) HORCM_DEV
The device parameter (HORCM_DEV) defines the RAID storage system device addresses for the
paired logical volume names. When the server is connected to two or more storage systems, the
unit ID is expressed by port# extension. Each group name is a unique name discriminated by a
server which uses the volumes, the data attributes of the volumes (such as database data, log file,
UNIX file), recovery level, and so on. The group and paired logical volume names described in
this item must reside in the remote server. The hardware SCSI/fibre port, target ID, and LUN as
hardware components need not be the same.
The following values are defined in the HORCM_DEV parameter:
•
dev_group: Names a group of paired logical volumes. A command is executed for all
corresponding volumes according to this group name.
•
dev_name: Names the paired logical volume within a group (i.e., name of the special file or
unique logical volume). The name of paired logical volume must be different than the "dev
name" on another group.
•
Port#: Defines the RAID storage system port number of the volume that corresponds with the
dev_name volume. The following "n" shows unit ID when the server is connected to two or
more storage systems (for example, CL1-A1 = CL1-A in unit ID 1). If the "n" option is omitted,
the unit ID is 0. The port is not case sensitive (for example, CL1-A= cl1-a= CL1-a= cl1-A).
