An HP Virtual Array 7400 (VA) is attached to my box by means of two fibre channel switches.
Command View 1.09 is installed on the system.
armdsp command shows LUNs defined on the VA. Each LUN is identified by a number and a WWN.
I didn't find a command to relate the LUN number with the device special file (for instance /dev/dsk/c4t11d2). The software for other HP disk array, as EVA or XP, contains commands to display this relationship (spmgr for EVA and xpinfo for XP).
Thanks.
Solved! Go to Solution.

Re: command to report info about LUN number and device file for a VA
# man armtopology
# armtopology host_name
Where host_name is the name of a server that is attached to the VA7400. You may have to execute it on each node.

Re: command to report info about LUN number and device file for a VA
# armtopology myhost
Host Host Node WWN Host Port WWN Product Serial Number C RG LUN Device Host Device Path
----------------------------------------------------------------------------------------------------------------------
# armtopology

spmgr is not installed because my disk array is a VA, not an EVA.

Re: command to report info about LUN number and device file for a VA
If not, then it may not work well. I *think* it is supposed to support talking to remote hosts, but I haven't been able to get that to work.
What happens if you just try:
# armtopology
For VA7400 armtopology is the command to use.
# man armtopology
for more info.

Re: command to report info about LUN number and device file for a VA
My host have has 5 IP addresses. The IP address needed to make armtopology to show the info doesn't match the IP address resolved for its host name. That was my mistake.
Patrick, please, answer again in order to assign you 10 points.
