You are proably better off asking the storage team... especially if you are not running EMC

Yeeeeeah..   This depends on a lot of different things.  What type of HBAs?  What type of SAN switch?  What type of SAN?

Depending on the HBA, there are utilities you can install from the manufacturer that will tell you the WWN of the adapter ports.  Depending on the switch, there are different commands you can use to find out where each WWN is plugged into.  Depending on the SAN, the management software can tell you the WWN of all associated HBAs and what LUNs are assigned to them.

You need to start by providing a LOT more information..

Yep.. don't try and guess WWN info. :)

Also, you can get the adapter WWNs from the BIOS when you boot the server..   Qlogic is cntrl-Q IIRC..   But, this may not be feasible for 80 servers..


Plus, you never mentioned even if this is FC or iSCSI.  I'm going to assume that it's FC, since iSCSI doesn't use WWNs, but I think the question is valid given your apparent novice skill-level with storage technology..  Just want to make sure.  You did say VLAN and Windows, so I'm not too sure now..

For the question you asked , it is not possible to know what WWN connceted to which switch port.
As a storage admin, you need to find it in the switch consoles.
Example :If you have a cisco SAN switch.Open device manager(sw used to manage the switch) and see the switch port properties , and the discription mentioned will tell you what host this port is connected.Other than cisco you have Mcdata and Brocade, both have thier own SW to view the port details.

If you have acess to switches the you can see port statistics , you will find wwn's loged in.

Other side , all EMC storage is discovered by a SW called Emc Control center.In this you can list which host is connected to what switch port.(go to relarions tab to view this).End to end connections are  graphically  presented in ECC.
Again these tasks are done by Storage admins.

Let me know if any more info required.

He asked for the possibilities, and they are listed well. If any more questions we are ready to ans on the same issue,
