XCP-ng 8.3 No Longer Compatible with Older Adaptec RAID Card?

Mentioning also @Team-Hypervisor-Kernel who now manages the drivers.

Maybe it's related to https://github.com/xcp-ng-rpms/microsemi-aacraid/issues/2#issuecomment-3837183087

It looks like the switch to the vendor driver instead of the kernel built-in for 8.3 (initiated by XenServer, and that we followed at the time as it was probably made in order to support newer cards) was not without drawbacks.

@dkg I have created a test installer ISO with an updated driver. Would you give it a go, and see if this fixes the issue for you? If you have any issues, then please provide us with the dmesg output during/after installation? Thank you.

ISO with updated AACRAID driver: xcp-ng-8.3.0-20250606-aacraid.iso (sha256: 6bd06036ea7f4f3788bdeab4663dc4359917a314b2b6859a88cce9f31b5a5ae2).

@dkg Please also note that you should not use @jul1an ISO installer on production environment. Only on test env where you can afford to break things and lose data.

I am s0lkanar1 in the https://github.com/xcp-ng-rpms/microsemi-aacraid/issues/2 thread. I'll reply there when I have more information.

I'll try more testing when I get a chance. I did try that test version first on a stripped down test computer with the relevant RAID card and the upgrade worked on the 2nd attempt, but when I tried on an in-use system with a bunch of running VMs, it was hanging on the install during my two attempts (the VMs were backed up in case of emergency). It didn't damage the 8.2.1 install. I didn't know to grab the dmesg output though before falling back to 8.2.1. It takes some time to set things up to do the tests, but I'll try to do that soon.

@dkg Oops sorry I thought you were someone else having the same issues.

I am using a translator because my English is limited. I have 5 identical servers equipped with Adaptec 6805 controllers. Previously, I bypassed the controller issues by using an alternative kernel, but that triggered network problems—specifically, network bonding is unstable on the alt-kernel.I have tested your evaluation image, but unfortunately, it did not resolve the issue. Later today, after my work shift, I will provide the logs and output from dmesg.I am ready to fully cooperate to fix this and can even arrange remote access via IPMI if needed.

@niko thanks, that would help a ton!

Hello, sorry for the delayed response. We had some issues with the Supermicro IPMI and were waiting for a resolution. Here are the two log files:

dmesg_xcp-ng-8320250606-aacraid-legacy.log

dmesg_xcp-ng-8320250606-aacraid-uefi.log

The alternative kernel did not work with your xcp-ng-8.3.0-20250606-aacraid.iso.

I am also providing the log after installing the standard xcp-ng-8.3.0-20250606.iso:

The files can be found at https://drive.google.com/drive/folders/1H-0FEruGK26oclD2WInDSOBJhVW2k8Xz?usp=sharing, as I wasn't able to upload the log files directly to the forum.

I am also ready to participate in any further testing of new images, up to and including XCP-ng 9.0.
