I have a 2x Node Windows Failover Cluster using Pure FC SAN storage. I receive multiple errors on each RDM DISK set to Physical Compatibility across multiple hosts.
Error - Failure issuing call to Persistent Reservation READ Reservation on Test Disk 3 from node "server name" when the node has successfully reserved. It is expected to succeed. The request could not be performed because on an I/O device error.
This occurs on all my RDM Disks and I only have this issue on MS Server 2016, not 2008 or 2012 R2.
Any suggestions would help and feel free to see attached screenshot.
