How to connect quickloop and fabric hosts connected to the same brocade 3800?

[Ramesh Donti]

Hi,
We are going to connect non-fabric aware HP-UX hosts (through quickloop) and fabric aware HP-UX 9000 hosts to HDS9910 through Brocade 3800 (firmware 3.02p) switches.

We have configured HDS9910 HBA's (CHIP ports) with "FABRIC ON and FC-AL" and on the switch side ports are configured for quickloop.
LUN security is enabled.

If all the systems (both fabric and non fabric aware) are connected in quickloop mode, we don't see any issue in the visibility of LUN's.

If we convert some systems to fabric mode by disabling quickloop on those ports, we are unable to see the LUN's for those systems alone.

We tried zoning fabric aware systems into separate zone and rest are left in the quickloop. Still, no result..

Any ideas..

Well, private loop and fabric is treated totally different in HP-UX (and other OSEes too) See
http://docs.hp.com/hpux/pdf/J2635-90014.pdf
You will need a quick loop zone on the switches which connects to the private loop hosts and ports on the HDS set to fabric off.
Then you need another zone a fabric zone which contains the hosts that can do fabric and HDS ports that have been set to fabric on.
I would not recommend to overlap fabric and quick lopp zones!

Cheers

Ramesh,
the rule is if you connect legacy host into QL mode this host will be able to see QL connected storage ONLY. For hosts to see fabric storage they should operate in public loop/fabric or storage devices should be moved into QL.
So for you there're only two solutions: move storage to QL or call HP and check if you can change your non-fabric HBAs for fabric ones
