* The disks are not visible to all nodes (even though they are in shared storage). Review the "{0}" test to see which disks are visible to all nodes. Ensure that the disks you want to test are unmasked, that is, your masking or zoning does not prevent access to the disks. If the disks seem to be unmasked or zoned correctly but could not be tested, try restarting the servers before running the validation tests again.
