The command device must be mapped to the SCSI/fibre using LUN Manager. You can define
more than one command device to provide failover in case the original command device becomes
unavailable (see
“Alternate command device function” (page 16)
). The mapped command devices
can be identified by the “-CM” of product ID field of the inqraid command.
# ls /dev/rdsk/c1t0* | /HORCM/usr/bin/inqraid -CLI -sortDEVICE_FILE PORT SERIAL LDEV CTG H/M/12 SSID R:Group
PRODUCT_ID
c1t0d0s2 CL2-E 63502 576 - - - - OPEN-V-CM
c1t0d1s2 CL2-E 63502 577 - s/s/ss 0006 1:02-01 OPEN-V -SUN
c1t0d2s2 CL2-E 63502 578 - s/s/ss 0006 1:02-01 OPEN-V -SUN
The command device of the UNIX host (Solaris) on the above example is described as follows.
/dev/rdsk/c1t1d0s2
The command device of the Windows host is described above example is described as follows:
\\.\PhysicalDrive2 or \\.\CMD-63502
After the process of command device mapping, set HORCM_CMD of the configuration definition
file as follows.
•
\\.\CMD-<Serial Number>:<Device special file name>
<Serial Number>: Sets the serial number.
<Device special file name>: Sets the device special file name of a command device.
Example
When the serial number, 64015 and device special file name, /dev/rdsk/*is specified:
HORCM_CMD
#dev_name dev_name dev_name
\\.\CMD-64015:/dev/rdsk/*
Out-of-band method
When executing commands using the out-of-band method, create a virtual command device. To
create a virtual command device, specify as the following to HORCM_CMDof the configuration
definition file.
•
\\.\IPCMD-<SVP IP address>-<UDP communication port number>[-Unit ID]
<SVP IP address>: Sets an IP address of SVP.
<UDP communication port number>: Sets the UDP communication port number. This value is
fixed (31001).
[-Unit ID]: Sets the unit ID of the storage system for the multiple units connection configuration.
This can be omitted.
Example:
The following expresses the case of IPv4.
HORCM_CMD#dev_name dev_name dev_name\\.\IPCMD-158.214.135.113-31001
The following expresses the case of IPv6.
HORCM_CMD#dev_name dev_name dev_name\\.\IPCMD-fe80::209:6bff:febe:3c17-31001
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
). 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.
