XP512, Red Hat Linux & QLogic
Anyway, I bet it would work regardless.

Re: XP512, Red Hat Linux & QLogic
Have a look at the following manual:
http://www.hp.com/cposupport/manual_set/lpg28612.pdf
On page 68, you will note the interface and mode settings.
HTH,
Dave

Re: XP512, Red Hat Linux & QLogic
See page 11 of the same document. It mentions not being able to configure LUSE devices on the QLA2200F interface. I'll see if I can find a more definitive answer.

Re: XP512, Red Hat Linux & QLogic
It would appear that the QLA2200F and the QLA2100F are supported on Red Hat Linux Version 6.0/6.1. However, the only shown supported card on Red Hat Linux version 6.2/7.1 is the Emulex LP8000, LP9000, LP9002, and LP952L. These cards support Private Loop and Direct Fabric Attach but do not support Fabric Loop. The Qlogic cards ONLY support Private Loop. I think that is probably the reason you see the change in support. Further, the change is for the ability to support the software suite. These HBA's also added boot support as well as N-Port fabric capability not supported by the QL2200F.
So, I'm sure you could get the QL2200F to work in Private Loop, however, you would lose the ability to run a large portion of the software suite and limit your capability in configuration. I guess if you're spending that kind of money on an XP512, I'd spend the few extra dollars on the correct/supported interface.
HTH,
Dave

Re: XP512, Red Hat Linux & QLogic
So back to my original question. Why not the QLA2200F HBA on Red Hat?

Re: XP512, Red Hat Linux & QLogic
Have you seen the driver link from Qlogic for Linux?

Re: XP512, Red Hat Linux & QLogic
I'm aware that the QLA2200F is a fabric aware card. You asked about the support on the XP512 and Red Hat Linux. I'm simply stating what HP's support documents state. On the XP512 side, what I provided to you is accurate. I can't give you a reason why the support is the way it is there must have been a reason fabric login to the XP512 is not supported on the QLA2200F. So, the QLA2200F will indeed work on Red Hat Linux versions 6.0/6.1. Although not mentioned in the support document, I'm sure they'll also work in the versions above 6.0/6.1, however, fabric login is not supported. I'm sure there is some reason that HA and Fabric Login is not supported but that reason is not disclosed in the document. So dependent upon what version of Linux were referring to, you are both correct and incorrect. As to whether it would work, it may, that's what development boxes are for right?

Re: XP512, Red Hat Linux & QLogic
We have been using 4 XP512's for over a year now and the QLA2200F card has been working flawlessly, point-to-point, in our W2K and Solaris environments and also supported by HP. Why not later versions of Red Hat? I can't let a reason such as, "that reason is not disclosed in the document", stop a vital project from coming online. If I do, I better have a reasonable excuse. I want to avoid turning this into a political issue between management at RIM and our HP account reps. A technical solution is much more feasible and to say the least, much more appealing. Ordering different FC-HBA's has it's own headaches because then we would have to alter the server and cluster architecture and re-certify that instead.
