You can run them at any time.  The AWRE change should be immediate, and
the defects command is just a status inquiry and won't affect anything.

Some drives don't update the current settings until the drive is reset,
so if "camcontrol mode da5 -m 1 -P 0" shows AWRE at 0 while "-P 3"
shows it at 1, you may need to reset the drive ("camcontrol reset da5"
with the vinum volume dismounted, or a power-cycle).
