HP XP P9000 RAID Manager Installation and Configuration User Guide (T1610-96046, August 2012)

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 examples
\\.\CMD-30095-250-CL1-A \\.\CMD-30095-250-CL1
dev_name for UNIX
In UNIX SAN environment, there are situations when the device file name is changed, a failover
operation in UNIX SAN environment or every reboot under Linux when the SAN is reconfigured.
The RAID Manager user needs to find NEW "Device Special File" and change HORCM_CMD
described in the RAID Manager configuration file. Thus, RAID Manager supports the following
naming format specifying Serial#/LDEV#/Port#:HINT as notation of the 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/
If these names are specified, HORCM finds “\\.\CMD-Serial#-Ldev#-Port#” from the device files
specified by HINT at HORCM startup. HINT must be specified “directory terminated with ‘/’ on
the device file name” or “directory including device file name pattern” as shown below:
/dev/rdsk/ → this finds a specified CMD from /dev/rdsk/* /dev/rdsk/c10
→ this finds a specified CMD from /dev/rdsk/c10* /dev/rhdisk → this
finds a specified CMD from /dev/rhdisk*
The device files discovered during HINT are filtered with the following pattern:
HP-UX:/dev/rdsk/* or /dev/rdisk/disk* Solaris:/dev/rdsk/*s2, AIX: /dev/
rhdisk* Linux :/dev/sd...., z/Linux : /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 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
\\.\CMD-30095:/dev/rdsk/c1 \\.\CMD-30095:/dev/rdsk/c2
