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). -- Dan Nelson dnelson@allantgroup.com
