Have a DELL Poweredge T110 ii with a S100 embedded controller and I just replaced a failed disk. Its a simple mirrored pair and when I assigned the new disk as a Global Spare the rebuilding starts. There is also 2 Virtual Disks on these disks and virtual disk 1 recovers with a state of ready but virtual disk 2 has a state of failed.

Anyone got any ideas why this would happen?

Are both virtual disks the same RAID level, or was VD2 RAID0? – MDMarra Mar 22 '14 at 15:05
Hi there both the same. Raid 1 – John Mar 22 '14 at 16:34

I would try removing the drive and rebooting, then shutting down to re-insert it again - force both virtual disk rebuilds to start again.

Alternatively, you may also want to double-check that you're running up-to-date driver and firmware versions for that controller too.

If this doesn't seem to work, it could be that the rebuild is failing partway through the 2nd virtual disk due to a bad block on the source drive... at that point, you may be stuck with backing up data and reimaging/restoring to give things a fresh start.

Thanks for the comments - I think it's going to end up being a bad block on the scource drive. Going to scan the drive now to confirm. Other wise i'll try your first suggestion. I've checked the drivers and firmware there all up to date. Thanks! – John Mar 26 '14 at 9:03
