mdadm: hot removed /dev/sdm
mdadm --add /dev/md0 /dev/sdm
mdadm: Cannot open /dev/sdm: No such device or address

The device is disabled at a 'hardware?' level -- I can't even cfdisk /dev/sdm

Okay, my array is degraded -- and the device /dev/sdm is disabled.

Short of a reboot, is there a way to re-enable the device? It's already flagged as faulty in mdadm.

man mdadm
mdadm --remove /dev/mdN /dev/sdm
mdadm --add    /dev/mdN /dev/sdm
