How to repair a degraded raid 0 array
Posted on 2007-12-03
I have a dell server with a build in sata raid. I am using raid mirror, and I had a hard drive fail. It degraded the raid, and I want to use a new drive in place of the failed drive. The only information I can find on the raid controller is that it is a CERC SATA 2S. Who makes this? I can't find any manual for it.
#1 The current drives are identical, and I don't know which one is bad... So I guess I just unplug one turn it back on and see if I got the bad one? Is this ok
#2 Once I get the bad drive out I'll attach the new larger drive, and tell it to rebuild the array is this ok? I know the array will be the size of the smaller drive.
#3 Could I use the array rebuilding process to create a backup drive for emergencies?
#4 Who makes the CERC SATA 2S. Is there a manual anywhere?
Thanks for any assistance.
