WinFix: Failover Cluster – Validate Windows Cluster Configuration shows errors in List Potential Cluster Disks having disk with the same disk signature

All local disks except System Drive and Paging (if paging is on different disk) and attached storage such as SAN/iSCSI will participate in Windows Cluster Configuration validation as potential cluster disk.

If there is error of multiple disks with the same disk signature, especially local disk, the validation will fail.

This is usually happens on Virtual Machine when the disks are clone.

Well, this issue can be fix by changing the disk signature using diskpart utility.
