Hello :)
Suddenly today there as an issue with a disk in an array. It appears as dead.
The array appears as degraded, but logical drive (RAID 5) is OK.
This has happened before, and I've just swapped in another empty hard disk without issue. However this time for some reason the new disk is just appearing as unconfigured without becoming part of an array.
The unusual aspect is that the logical drive is still appearing as OK instead of degraded. It's like the controller hasn't fully worked out that there's a problem.
What can I do to add the unconfigured drive to the degraded array? Commands `rebuild`, `migrate`, and `transit` don't seem to allow this. I'd quite like this to get done quickly as I don't like that one of the other disks is in PFA status, I want to replace that one manually too.
