Promise TX2 Rebuild via atacontrol?? - FreeBSD

All, I have a failed member in a RAID1 array and using atacontrol can see that the status is degraded. I am curious if I can use atacontrol to rebuild the array if the original array was built using the Promise BIOS utility. If I tell atacontrol to rebuild.will it corrupt my data or catch fire and explode?? Cheers!...

    even in atamkII in 6-current.
    If you replace the failed drive it sould be automatically rebuilt, the
    `atacontrol rebuild ar0` doesn't work as long as you (in 5.x) used "addspare"
    or the controller found a good "spare" drive.
    In 4.x you don't have the addspare option, you have to `atacontrol detach 3`
    and reattach it the same way to get recognized and inserted as spare in an
    existing array.

    I apologize...I usually am the one complaining to others about
    versioning...my bad...

    I do not think that the drive is at fault as much as the controller. I have
    had to deploy well over one hundred of the exact same configuration, and
    historically, it's always been the controller that just drops the drive for
    some reason. I usually end up re-mirroring the array on the old "dead" drive
    and the system will continue on its merry way (last one is over 1 year old
    since last resync)...hence you see why I am curious if I could just use
    atacontrol instead of taking the unit offline and spending 45min waiting for
    the resync....
