Two disks have been found on node {0} with duplicate disk signatures. The disks involved are physical disk {1} and physical disk {2}. There may be a Multipath I/O (MPIO) problem such as the software is not installed or is not working properly. If MPIO is not involved, or MPIO has been verified as working, you must either mask one of these disks off at this node, or run validation and specify a disk list that includes only one of these disks, for example by using the Test-Cluster cmdlet in Windows PowerShell.
