Hi Marco,   Sorry for the late reply. Ironically the Storage arrays is what is hosting our backups.   I restarted the server and it then only started rebuilding disk 0:2:11 and it stopped showing duplicate disks. We also did replace disk 0:2:3 and it still says "Ready" state.   Although it seems fine now. Thank you.
Good day Dell Community,   I took over a Dell OMSA Server that has 3x RAID 5 Storage Arrays connected to it. Usually we receive a notification that a drive has failed and we need to swap it out, last week when I checked it and I noticed the same Physicall Disk is showing multiple times, 30% of it is Foreign,30% is rebuilding and the rest is Online in the State. When counting the same disk is showing as 20 separate disks but they all have the same name and revision number.  [IMAGE] Its strange because I know there are only physically 12 3TB disks in that Enclosure.   Any help or advise will be greatly appreciated.
