Hello,
We have created 2 Guest VM's running Windows Server 2012 R2 on VMware ESXi v5.5 host.
Both these VM's are on same subnet and have been setup in a Cluster configuration using Failover Clustering. Quorum Disk is assigned as an RDM disk using Physical sharing capability and SCSI Controller as Para-Virtual. the disk has same drive letter assigned on both the nodes and visibility is fine. However, when we run the Cluster Validation, it fails with error "failed to access sector 11 on physical disk a3ec0854 from node xxx.yyy.com. the request could not be performed because of an I/O device error".
1. Googled the issue and found an article about Persistent Reservation. So cleared that using Clear-PersistentReservation command under Powershell, with a no-go.
2. Tried a different quorum disk, with a no-go.
3. assigned altogether new disk and still the same.
Kindly help us with this issue. Its a production server.
