Support for newer Emulex LPe37xxx amd LPe36xxx Fiber channel adapters on XCP-ng 8.3 - your testing is needed

MrQ

We have been working on a version of the emulex-lpfc RPM package that would support both old and new hardware (the work-in-progress documentation can be found at https://github.com/xcp-ng/xcp-ng-org/pull/518), and we would really appreciate your help testing the installation ISO or the updated RPMs to make sure it works as expected on your hosts.

The new (testing) ISO can be found here

The updated RPM can be pulled directly from here (to update the driver on an already installed XCP-ng host):.

The new RPM bundles two different versions of the lpfc kernel module, lpfc.ko handles the Emulex Fiber Chanell adapters that were already supported while a lpfc14.ko handles the newer generations.

Whether you are running an older generation Fiber Chanel Adapter or a more recent one, it would be great to get confirmation it works for your use case!

Any remarks on the documentation PR is welcome too!

I went digging and three threads turned up people who already have this hardware.
@yeopil21 in https://xcp-ng.org/forum/topic/11799 had an LPe37102-D on a Dell R770 that never showed up at all, @jinju0504 in https://xcp-ng.org/forum/topic/11946 ended up on the -alt package on an R670, and @lukas in https://xcp-ng.org/forum/topic/8847 was running an LPe31002-M6-D with NVMe-oF back on 8.3 beta2.

That last one is the older generation, so I'd guess it's the side where you most want to hear nothing regressed.

Tagging them in case the cards are still on their benches.

Good morning

So I might've found an issue with this driver release. That I'm trying to troubleshoot and collect data on.

We have two LUNs presented to our dev-pool (xcp-dev), running on R650xs. When I have attached one LUN to xcp-dev I can't see the other LUN.
This works on our older R350s

Removing the attached LUN, makes a LUN visible again. But now we're getting some strange behaviour. And looking into if it is misconfigured from the Dell Powerstore, or if it is on the host(s) itself.
