Hi Ryan,

Thanks for your reply. I have submmited a merge request for this issue.

Yes, we ran into the issue when we were qualifying Ubuntu 20.04 to run on our platform. Our SCSI adapter advertises SCSI_IDENT_TARGET_VENDOR as "clusterid='<CLUSTER_ID>'", where <CLUSTER_ID> is unique cluster identifier.

Due to this issue, Ubuntu 20.04 cannot be installed on our hypervisor until we either stop providing vendor-specific id on SCSI adapter or we bypass (use different disk type/bus) SCSI adaptor. I attach screenshot with the error message we get during installation (I feel super ashamed to attach screenshot and not a text log, but I didn't have a chance to collect the logs).

Thanks.

BR,
Sergey
