I'm not to sure if you can get the WWN from the OS but the LUN can be obtained by [blue]lsscsi[/blue] (last column) or from [blue]cat /proc/scsi/scsi[/blue].

You should be able to get the WWN from the FC switch. The switch deals with the WWN directly. The drivers hide the entire FC fabric from OS.

Have Fun!

Hi Thanks for reply

lsscsi does not work "command not found"

when we cat /proc/scsi/scsi how do we determine which which mounted??

[root@sunatlsunx004 root]# lsscsi
-bash: lsscsi: command not found
[root@sunatlsunx004 root]# lscsi
-bash: lscsi: command not found
[root@sunatlsunx004 root]# more /proc/scsi/scsi

I assume you're running RHEL(2 ???). I'm afraid you need a 2.6 kernel to use lsscsi. Sorry 'bout that.

From what I can gather you have two (2) SCSI adapters, scsi0 and scsi1. Correct?

You also have two (2) Direct disks, sda and sdb, attached to adapter scsi0. Correct?

Host: scsi0 Channel: 00 Id: 00 Lun: 00 --> boot device? (/dev/cciss/c0d0p?)
Host: scsi0 Channel: 00 Id: 00 Lun: 01 --> /dev/sda
Host: scsi0 Channel: 00 Id: 00 Lun: 02 --> /dev/sdb
Host: scsi0 Channel: 00 Id: 01 Lun: 00 --> Another device on the same adapter (??)
Host: scsi1 Channel: 00 Id: 00 Lun: 00 --> Some device on the second adapter (??)
Host: scsi1 Channel: 00 Id: 01 Lun: 00 --> Another device on the second adapter (??)

You know your system better than I do. Narrow the choices by deducing what's left. I need more info to be helpful.

Try using [blue]cat /proc/mounts[/blue] and [blue]cat /proc/partitions[/blue] to get a better picture.

It might be time to call HP to get a real answer.

Have Fun!
