Raid Failure and Recovery

By tmiller ·
I have an older server that I am running Windows 2003 and exchange 2003. Last night I had 2 of my 5 hard drives fail on me. I am running a raid 5 each of the hard drives are 9.1 GB.

I found a source for replacing the hard drives but I am wondering if it is possible for the server to rebuild the 2 failed drives? I am also wondering what kind of steps would be involved, and things that I should look out for? At this point the Server will not boot, it comes to the message that I need to replace the drive(s) in bank 0 and 4.

In the meantime I am going to setup Windows 2003 and Exchange 2003 on a spare PC that I have laying around so that we can recieve emails while I work on recovery.

Any insight into this situation would be greatly appreciated. I am going post an alternate email address for people to respond to seeing that my current server is dead.

RAID5 can rebuild only if one of the harddrives fails. In your case, with two failed drives, I am afraid you won't be able to have the array rebuild.

lowlands is correct. If 2 drives in a RAID5 array fail, then the data is lost. If there was a hotspare you MAY be ok as the hotspare would have taken place of one of the failed drives leaving you only down one drive (well 2 actually, but only one in the array plus the failed hot drive)
