Last weekend a disk in my RAID failed.
Here's what I saw on a Ctrl-I
Port 0 is the ssd boot drive
The other three were all 1tb drives configured as RAID5
A little research soon confirmed that that model/serial combo on port 2 is Seagate-ese for 'It's stuffed'
I swapped the drive for another 1tb Barracuda and powered on.The Option Rom now showed the new drive as non raid on port 2 and the volume remained as failed
As I was now able to fire up the OS I went in to the management app and saw:
Rebuild has not kicked in and I can't see any option to start it
Any ideas for me?
In this case the status of the RAID volume is not "degraded" as if only a single drive was bad; instead, the whole RAID structure of the array has failed and therefore it is not possible to recover it.
