Comment 2 for bug 1812665

We found the issue, it turns out OS brick and HP's AJ76A HBA don't play nicely together.

I had this same HP HBA in my controller and one of my compute nodes.
Both of them I had hit the same error
NoFibreChannelVolumeDeviceFound: Unable to find a Fibre Channel volume device.

Create volume from image failed, attach volume failed, back of a volume failed.

However on a second compute attach volume worked, it just so happens that compute used another type of HBA. Working on a hunch I had swapped my controller's HBA to Qlogic, create volume from image works.

The odd thing is the HP AJ764A HBA is based on same Qlogic QLE2526 chip on my "working" HBA.
So same chip set Qlogic branded HBA works while HP clone doesn't.
