WWN not visable on brocade switch port

soulman — Tue, 07 May 2013 13:45:09 GMT

Hi All,

I have a number of BL465c G8 connected to a C7000 chassis (Slot1-4 and 12-16). Bay1,2,5 &6 have 10GB Pass-thru modules. Bay3&4 have Brocade 8GB/24C FC switches.

The Servers have 2 onboard 10GB passthru connectors, slot1 has Qlogic FC card, and slot2 has another 10GB passthru connectors.

Now all is green and connected from the OA and I can see the WWN, now on the Brocade switches non of the servers are connected to their relevant ports i.e. blade is switch one should be connected to port1 on both switches, but I get nothing. When I run the cmd switchshow and portshow there are no devices or the Qlogic WWN being displayed.

I have reset the Swicthes and servers and have also rebooted the OA.

Has anyone got any ideas?

Its been raised with HP, but wanted to see if anyone else has ever had this issue.

Is an OS running on the servers already?

No OS

No OS, no driver, no fabric login.

All is pretty normal.

If you enable the FC BIOS of the HBAs, they will log on and will be visible.

You need to enable the BIOS only for boot from SAN.

Thanks I'll give that a try but the very least I would expect to see a link light on, on the Brocade switch to show there is connectivity.

I may well be wrong!!!

I have also set it to boot from HBA1 and still see no link light.

But I'll install an OS with correct drivers and see if that works.

To enable the HBA BIOS you have to go into during boot (not into the servers BIOS!).

Let me re-phrase - I have set the Bootup options in the BIOS to boot from HBA

This is changing nothing.

As long as there is no driver loaded, the adapter will not do a fabric logon.

If the boot bios *inside* the adapter is enabled, the adapter will do a log on on its own in order to boot from SAN.

IIRC you need to press CTRL A or something to get into the utility.

Thanks Torsten - After doing a quick install of ESXi I've seen the HBA connect to the FC Switch on the correct port and correct WWN.

Your help is appreciated
