Hello Vladimir:

What drivers are  you using on your Cent OS?

I think you want the Cent OS command and not the switch command.  Is that right?
If so, and you are using Emmulex, try looking here: http://www-dl.emulex.com/support/linux/820121/linux.pdf

Not that you asked, but if you configured the cDOT LIFs before the fabric was ready, you might try using “admin down” and then “admin up” on the LIFS and then waiting.
However, all the switch information below is worth a long look because the Cisco switches can be a little different to work with than the Brocades.  I don’t think you
 specified.

You may need to be in priv set advanced or diag depending on the version of Data ONTAP.

I hope this is what you're looking for.

Share and enjoy!

Subject: FCP switch / port info

Hi All,

With OnTAP 8.x (afaik), it became possible to see what FC switch name / port number a filer is connected to on SAN:

filer> fcp show adapters -v
..
Switch Port:             fc-corp-203:22

// fc-corp-203 - switch name
// 22 - port number

I assume a certain FCP request makes it possible and wonder if a similar tool is available on a Linux server (Im running CentOS mainly). Is anybody aware of such a tool / utility?

Cheers,
Vladimir
