find WWN without OS

[Mariusz Grabowski_2]

Hi,

I'm trying to figure out WWN numbers of FC adapters in a host, which does not have an OS yet. Of course, eventually I'll have OS installed, but I need the wwns right now to prepare fc connections..

How this can be figured out?

thanks, Mariusz

Hi,

you can attach the server to a FC-Switch and check the port on which the server is attached. Sometimes the WWN is printed on the FC-Adapter.

Hi Mariusz,

You can use FCA BIOS - one of the options in the BIOS should tell you the WWN of the cards. For example, for Qlogic FCAs, at server POST, hit Ctrl-Q to get into FCA BIOS - Select your adapter and you will get your FCA WWN.

Alternatively, yes you can just connect your FCAs to a switch and perform "switchshow" and check out the switch port to which the server FCAs are connected to. The switch's name server presents the FCA WWN here.

Hope it helps.
