First off, do you have a backup of the RAID data? Before you proceed with any more attempts to restore the RAID it's important to know this, as your efforts to go back online can cause further data loss.
Hello everybody. I'm having a problem with my RAID 10+0.
2x 3ware 9650SE Raid Controllers;
16x HGST 2TB HDD (8 drives per controller);
Windows Server 2008 R2
Controller 0 has 8 Drives set as RAID 10 (one unit with 8TB);
Controller 1 has 8 Drives set as RAID 10 (one unit with 8TB);
Windows joining the two units in RAID 0 (stripe) (three logical volumes adding up to 16 TB);
We had a power failure and lost 3 drives from Controller 0. Even though they were not part of the same subunit pair (so there was no data loss), the entire unit was set as Inoperable. I contacted 3ware support and they wrote an script to back the controller up to the degraded state. The rebuild occurred successfully and both units show as OK on the controllers.
But the Windows RAID 0 array is broken.
Trying to reactivate the disks doesn't do the trick. If I set both Disk 1 and Disk 2 to offline, disconnect the units and then rescan the controllers, the 1st Controller scanned always gives an Online healthy Disk and a Missing Disk on the Server Manager and the 2nd always gives an invalid disk. Doesn't matter which controller (0 or 1) I rescan first, the second to be scanned always gives an invalid disk.
Is there anything I could try to bring this array back up?
Thank you for reading.
