Unlike hardware RAID controllers, mdadm may not support true hot swap.
You may have to disable/offline the disk in mdadm before removing it from
the server chassis -- reboot is definitely not needed.
I was also doubtful about mdadm being able to support controlling the
hot swap bay LED. I suspect the failed disk would be taken out of
the array by mdadm anyway. I am not sure if disabling the disk would
be required.
I have concluded that it is best to go with a h/w raid controller.
Thanks.
