we usaly break the mirrors then patch , then re-mirror.

raidctl -d c0t0d0

do patching
reboot

raidctl -c c0t0d0 c0t1d0




if things go bad, phisicaly swap the disks and re-boot.

Don't you need to boot from CD in order to enable the mirroring again? If you do not boot from CD and do "raidctl -c c0t0d0 c0t1d0" you will get an error that says "Array or disk in use"!

you must delete the raid first and then recreate it

The raid was deleted first as you an see below:

# raidctl
Controller: 0
Disk: 0.1.0
Disk: 0.3.0
# raidctl -c c0t1d0 c0t3d0
Creating RAID volume will destroy all data on spare space of member disks, proceed (yes/no)? yes
Array or disk in use.

Am I missing something?
