Foreign Disc's in RAID 5 Array
Posted on 2012-09-01
The RAID controller is a PERC 6/i controller. The raid array is made up of 3 x 500GB drives.
We recently had a power outage which resulted in our Windows server failing to boot.
The customer has not made any backups of the data.
Upon boot we receive a message stating Foreign configurations found on array. Press F to import configurations. Or press c to load the configuration menu. The server will not boot passed this point.
When I press F to load them it opens the configuration menu Where it shows drives 2 & 3 as missing under VD MGMT. Under PD MGMT it shows drive 1 online, drives 2 & 3 show foreign. Under Foreign View, Drive 2 shows a state of Rebuilding and Drive 3 shows Online.
How can I re-join the drives to the current RAID 5 array? Note that they were never removed and no configuration changes were recently made, last change made approx 2 years ago. The only thing that happened between it working and it failing was a power outage.
The only experience I have had with this was when I had to migrate an array from 1 failed server to a server with identical hardware in which we had to delete the array and re-create the array without initializing. This allowed us to boot the server without problem, just had to re-activate windows. In that situation however the customer had a backup of all data.
Am I looking at the same scenario, or are there other options?
