what command to use to see VA disks

[Brett Hawson]

To see XP disks attached to a machine you use xpinfo -i what would/do you use to se VA disks attached to machine, and if there is such a binary, where could I locate it?

armdsp -a array_alias

Where can I find armdsp?

/opt/sanmgr/bin

You need to install HP Surestore Command view SDM product that comes with the VA array.

Brett,

assuming that you have CommandView installed, you would first run
# armdiscover
(takes a while)
then
# armdsp -i

Maybe I'm not making myself very clear. I'll try to explain what I'm looking in a clearer way.

We have a department which attach san disks via fibre optic to different HP-UX boxes. to see the san disks attached, we run xpinfo -i which the san guys, have placed the xpinfo binary in /usr/contrib/bin. We now also have some VA disk arrays and the san guys have attached some san disk to a particular box.

Now apart from ioscan, I was wondering if there was another command I could run on the HP-UX box which would show me the VA disk attached.

I checked with the san guys and armdsp -a -array_alias will show me all array information. I only need to know what disk is attached to the box, so I would like to locate a binary file that I can put in /usr/contrib/bin and execute, with the same results of the xpinfo -i command.

Hope it is clearer.

Brett

Hi Brett,

armdsp -f array_alias

will show the information that you need. It basically lists the status of all the FRUs including the disks.

Refer to the following PDF file for more info (pg no:111)

Hope this helps,

Also,

armdsp -d fru/ID array_id

shows you more information for the selected disk.

Note: You need not necessarily install "Command View SDM" Software on all the systems that are connected to the SAN. Install it on one system and manage the disks from that.

/opt/sanmgr/commandview/client/sbin/armdsp.

I'd link it there though..

I have this niggling feeling that this is not going to answer the whole question as the SAN guys will start to ask about fibre topology.

IF you use direct attached point-to-point then ioscan + armdsp -a .

If you run through fibre switches then things get more complicated. I'm @ home so will not be 100% about the next stuff... Basically thee is a file in /opt/sanmgr/commandview/client/config called something like PanConfFile.txt. In there you can add/find a line something ARMTOPOLOGY_FORMAT = .....
the default is not good enough & you want to add DB_PWWN to the defult. IF there is no ARMTOPOLOGY line simply do man armtopology & it is within the first page, just add DB_PWWN.

then run armtopology & armdsp -a bingo the topology can be shown by matching the /dev/dsk/cXtYdZ with the DB_PWWN (the port WWN of the controller). Now the SAN guys will be happy..
