[ClusterLabs] (ELI5) Physical disk XXXXXXX does not have the inquiry data (SCSI page 83h VPD descriptor) that is required by failover clustering

Anyone that follows this mailing list at all has probably noticed that I’m creating a 2-node HA iSCSI Target on RHEL 6 using Pacemaker/Corosync (and CMAN, I guess) and the available tgt scsi tools to use as shared file system for some Windows Server Failover Cluster nodes. After a great deal of trial and error, I’ve finally had success getting this to work, but I’m running into an issue with the file systems passing cluster validation on the Windows side. Initially, I was getting an error that the iSCSI target didn’t support SCSI-3 Persistent Reservations, which I was able to get around using the fence_scsi stonith module. I’ve found some extremely detailed conversations about the SCSI page 83h VPD descriptor error on the internet, but, frankly, I simply don’t follow them. Could someone ELI5 how to fix this **without scst, lio, lio-t**. Thanks!
