  Try to force 0:0 online. If forcing 0:0 online allows you to access your data then: If you cannot force 0:0 online or it goes to a failed state when you try then try to force 0:3 online. If forcing 0:3 brings the array back to life then: You do NOT want to force a drive online unless you have to. If you are able to get the data back by forcing a drive online then you will want to rebuild the other drive. You do not want to force a second drive online after you successfully get the array back online. Forcing a second drive online in that scenario will definitely corrupt/delete the data on the array. Once you get your data backed up and the array back to an optimal state you can test the drive you replaced with diagnostics to determine if you should throw it away. Since you already have replacement available I would just replace the drive to speed up the process to get the array optimal again. Thanks
I have an old PowerEdge 4400 and it went down this week.  I went into OpenManage Array Manager and it shows me  Array 0:0 degraded Array 0:1 Ready 68.37 GB Array 0:2 Ready 68.37 GB Array 0:3 offline Array 0:4 Ready 68.37 GB Array 0:5 Ready 68.37 GB Array 0:8 Ready 68:37 GB Array 0:9 Ready 68.37 GB I am not sure exactly what this means.  I have one degraded and one offline.  However, all links on all drives have one green solid light. Virtual Disk 1 Ready RAID-5 472.90 GB I am purchasing two new drives. Should I right-click on the offline drive and "prepare to remove" -- my only option and put in a new one? Or should I do something first with the degraded one? What do I do?
RAID5 Degraded or Dead?
