Can't readd 300GB SAS Drive to array

Recommended Posts

I had a failure on a 300GB SAS Drive in my array of 9 x 300GB SAS drives, 4 x 3TB WD Reds, 4 x 4TB Wd reds and 2x 6tb wd reds for parity

I replaced the drive with another 300GB Sas drive but when I select the new drive the page refreshes but the drive isn't selected anymore

 

I tried doing a new config; the wd reds get readded fine and ready to start the array but all 9 of the 300gb sas drives can't be added; after the page refreshes the drive goes back to unassigned

 

HELP GUYS!!

You shouldn't have done a new config with a disable disk, but if you didn't start the array yet it may still be possible to recover that disk, do the following:

 

-new config, assign all disks (including new 300GB disk), looks like you have dual parity so order of all disks has to be maintained as it was before

-check both "parity is already valid" and "maintenance mode" before starting the array

-start the array

-stop array, unassign disk to rebuild

-start array, check emulated disk mounts and contents look OK

-stop array, reassign disk

-start array to begin rebuild
