We had a power failure at a remote site.
The domain controller at that site will not boot. Error message: "Error loading operation system".
The DC has 2 physical HD's
The RAID card is an LSI ATA-100 and was configured on the 2 physical drives as RAID 1 and has been running fine like this...
After the power failure a new RAID 0 array has somehow created itself and one of the 2 drives added itself to this new RAID 0 array and this array is showing as healthy and online while the original RAID 1 array is in a degraded state....
Any ideas on how to proceed to safely remove the RAID 0 array and add the drive back into the mirror?
Thanks in advance!
