Re: San disk identification on cilent2013-02-01T11:26:17Z in response to SystemAdminA lot depends on how you have the disks assigned, and you do need root access to the partition to do this. Here are a couple of things that work for me.
echo cvai | kdb
This will tell you which vio server is supplying the vscsi device. You can then associate this with the disks by using lspath.
odmget CuAt | grep -wp hdisk##
This will give you info on the disk and typically, hidden in the unique_id is something that identifies the SAN and the disk id. In my case I have an EMC SAN, so EMC is embedded in the unique id.
Hope this helps.

Re: San disk identification on cilent2013-02-01T15:25:22Z in response to SystemAdminDo you have access to the LPAR profile from the HMC?
From the profile you can see which virtual scsi adapter has been assigned from each VIO and then
use that to follow the trail to the disks.
The "virtual_scsi_adapter" field in the profile will show something like "100/client/1/vioA/100/0"
Then, on your LPAR when you do "lsdev -Cc disk" to see the location of the disk you should see 100 as part of the location code.
