I restarted my UnRaid 6.9.2. system a week or two ago after months of being turned off (for non-technical reasons).  It was fine for a bit but then I got "device is disabled" on disk 3.   I thought it might be cables or my disk.  I downloaded diagnostics, powered down, checked cables (they seem OK) then powered up again.  It's still disabled.  I reran diagnostics.  As far as I can tell the SMART data is OK.  Diagnostics from before and after power down are attached.

 

What do I do to get disk3 out of its disabled state?  I have a new disk ready to go if it's needed - in fact if appropriate I'd rather rebuild onto the new disk - I need to add some extra space to my array anyway, and the new disk is 10Tb as opposed to disk3 which is 6Tb.

 

Thanks as always for your help.

It does look like a power/connection problem, but once a disk gest disabled it needs to be rebuilt, since the emulated disk is mounting you can rebuild on top, would still recommend replacing/swapping cables to rule that out id it happens again to the same disk.

Thanks JorgeB, I'll test the cables by swapping out.  Is it possible under these circumstances to rebuild onto a new disk instead of onto itself?
