NWCONFIG-X-178: Two volume segments with the same sync value have mismatched data. message
Source: NWCONFIG.NLM
Explanation: NWCONFIG found multiple instances of the same volume. This probably occurred because two physical disks each contain a volume with the same name.
Action: Because each volume on a given server must have a unique name, take one of the physical disks offline. You might have to delete one of the volumes and then bring the disks online simultaneously.
