atacontrol -> camcontrol in FreeBSD10+

[Robert Huff]

     I just updated a system to:

FreeBSD 11.0-CURRENT #0 r263263: Mon Mar 17 15:09:18 EDT 2014 amd64

     According to src/UPDATING, this means "camcontrol" is now the 
correct tool for both SCSI and IDE/ATA drives.
     This system has an external hard drive dock, connected to ada1 via 
eSATA.  Every so often the drive gets swapped, causing it to disappear 
from /dev.
     Previously

root> atacontrol ata0 detach
root> atacontrol ata0 attach

     would get it back.
     I am unable how figure out the equivalent using camcontrol, in part 
because many of the commands are explicitly tagged "SCSI".
     Anybody out there know how to do this?

     Respectfully,
