Horcm_Cmd (Out-Of-Band Method) - Hitachi VSP F1500 User And Reference Manual

\\.\CMD-30095:/dev/rdsk/
• Command devices in the multi-path environment
Specify storage system's serial number 30095 and LDEV number 250 as
follows:
\\.\CMD-30095-250:/dev/rdsk/
• Other specifications
An alternate path with storage system's serial number 30095 and LDEV
number 250 can be specified as follows:
\\.\CMD-30095-250-CL1:/dev/rdsk/
\\.\CMD-30095:/dev/rdsk/c1
Note: If the hardware configuration is changed during the time an OS is
running in Linux, the name of a special file corresponding to the command
device might be changed. At this time, if HORCM was started by specifying
the special file name in the configuration definition file, HORCM cannot detect
the command device, and the communication with the storage system might
fail.
To prevent this failure, specify the path name allocated by udev to the
configuration definition file before booting HORCM. Use the following
procedure to specify the path name. In this example, the path name
for /dev/sdgh can be found.
1 Find the special file name of the command device by using inqraid
.
command. Command example:
[root@myhost ~]# ls /dev/sd* | /HORCM/usr/bin/inqraid -CLI |
grep CM sda CL1-B 30095 0 - - 0000 A:00000 OPEN-V-CM sdgh CL1-
A 30095 0 - - 0000 A:00000 OPEN-V-CM [root@myhost ~]#
2 Find the path name from the by-path directory. Command example:
.
[root@myhost ~]# ls -l /dev/disk/by-path/ | grep sdgh
lrwxrwxrwx. 1 root root 10 Jun 11 17:04 2015 pci-0000:08:00.0-
fc-0x50060e8010311940-lun-0 -> ../../sdgh [root@myhost ~]#
In this example, "pci-0000:08:00.0-fc-0x50060e8010311940-lun-0" is
the path name.
3 Enter the path name to HORCM_CMD in the configuration definition file as
.
follows.
HORCM_CMD /dev/disk/by-path/pci-0000:08:00.0-
fc-0x50060e8010311940-lun-0
4 Boot the HORCM instance as usual.
.

HORCM_CMD (out-of-band method)

When executing commands using the out-of-band method, use a virtual
command device instead of a command device. By specifying the location to
create a virtual command device in HORCM_CMD, you can create a virtual
command device.
The location where the virtual command device can be created is different
according to the type of the storage system. For details about locations, see
