I have a Dell Poweredge R710 with a Perc H700 Raid controller. It's in a RAID 6 configuration currently with 2 failed disks. It does boot to CentOS in it's currently degraded state.
I would like to replace the disks, but whenever I add a new one and run a rebuild it runs for a few minutes then puts the new disk offline. It does this for both slots on the controller and for two brand new disks (same model as existing).
I think the battery on the controller needs replacing, but I wouldn't think this would affect the ability to run a rebuild.
Any ideas on how to get a rebuild to complete?
