HP XP7 Storage - Manual (Page 30)

To allow more flexibility, RAID Manager allows the following format.
•
For minimum specification
Specifies to use any command device for Serial#30095 \\.\CMD-30095 If Windows has
two different array models that share the same serial number, fully define the serial number,
ldev#, port and host group for the CMDDEV.
•
For under Multi Path Driver
Specifies to use any port as the command device for Serial#30095, LDEV#250
\\.\CMD-30095-250
•
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
•
Other example
\\.\CMD-30095-250-CL1-A
\\.\CMD-30095-250-CL1
dev_name for UNIX
In the UNIX SAN environment, a device file name is changed at the failover operation under the
UNIX SAN environment, or each reboot process under the Linux when the SAM is reconfigured.
RAID Manager user is required to change the HORCM_CMD described in the RAID Manager
configuration file by searching new "Device special file". Therefore, RAID Manager supports the
following naming format to specify "Serial#/LDEV#/Port#:HINT" as an expression way of command
device for UNIX.
\\.\CMD-Ser#-ldev#-Port#:HINT
HORCM_CMD
#dev_name dev_name dev_name
\\.\CMD-30095-250-CL1-A-1:/dev/rdsk/
once this name is specified, HORCM finds the "\CMD-Serial#-Ldev#-Port#" from the device file
specified by the HINT at the time of HORCM startup. HINT must specifies to be end with "/" for
the directory of the device file name or the directory that includes the pattern of device filename,
as shown in the following.
Finds CMD, which is specified by /dev/rdsk/:/dev/rdsk/*
Finds CMD, which is specified by /dev/rdsk/c10:/dev/rdsk/c10*
Finds CMD, which is specified by /dev/rhdisk:/dev/rhdisk*
A device file is displayed while HINT is filtered with the following pattern.
HP-UX: /dev/rdsk/* or /dev/rdisk/disk*
Solaris: /dev/rdsk/*s2, AIX: /dev/rhdisk*
Linux: /dev/sd...., zLinux : /dev/sd....
MPE/iX: /dev/...
Tru64: /dev/rrz*c or /dev/rdisk/dsk*c or /dev/cport/scp*
DYNIX: /dev/rdsk/sd*
IRIX64: /dev/rdsk/*vol or /dev/rdsk/node_wwn/*vol/*
If HINT is already specified, ":HINT" can be omitted with the following command devices, and
the command devices are retrieved from the already stored Inquiry information, which is not
required to execute device scanning.
