rescan causes offlined tape to reload

[G. Paul Ziemba]

I have a DLT7000 scsi tape. Behavior of "camcontrol rescan all"
seems to have changed between FreeBSD stable of 2009-Nov-17 and
2011-Jan-11. 

I execute the following sequence of commands:

# camcontrol eject sa0
# camcontrol rescan all

If there is a tape in the drive, the "eject" unloads it.

On the old system: the rescan command does not affect the state of the tape.

On the new system: the rescan command causes the tape to load. It seems
incorrect to me.

Is the new behavior a bug?

thanks,
