I'm new to SAN storage so I was wondering if someone can assist me with a problem. I have a solaris 10 OS with 3 SAN devices attached. We are trying to troubleshoot performance so I was asked to get the WWN of each SAN disk and show what it's attached to via the SVM mount in the metastat output.
I can get what HBA controller it's attached to and the controller HBA by doing:
I just can't figure out how to get the WWN for that actual device.
I have tried searching google, but everything always points to getting the WWN of the HBA card. I'm beginning to think from an OS level it's not possible to get the WWN of the actual SAN disk. Can someone please confirm if you can or not and if you can please point me in a direction on how to obtain it.

This may sound like an absolute rookie question, and it is.
I have been working on Migrating our HP and Solaris servers to the new EMC SAN and know the routines backwards.
Now we've suddenly got a new IBM server and I don't even know how to check if it is connected to the switch.

I have my application vendor looking at this but I want to do my own investigation.
