NWCONFIG-X-191: Two or more volume were found which have the same name. (Volume name has multiple definitions for segment number.) This could be due to formerly mirrored volumes being synchronized separately, then brought online together. If this is the case, unload the drivers or take the server down, and then bring the separate disks online one at a time. Rename the redundant volumes as they are brought online, so that there is not a name conflict.
Source: NWCONFIG.NLM
Explanation: More than one volume was found 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.
