>Description:
Since 'od' isn't a CAM driver, shouldn't 'da' support
the 'CDIOCEJECT' ioctl, which is used to eject a variety
of removable media (e.g., ZIP drives)?

Having a way to programatically eject ZIP disks is quite
handy; using 'od' on 2.2.X, I had edited rc.shutdown to
eject any ZIP disks, which avoids some painful drive-lettering
problems when you boot Windows.  (It also ejects the disk,
which is otherwise impossible---at least for internal
drives---without turning the machine back on.)

				- Tim Kientzle

>How-To-Repeat:
The command: cdcontrol -f da0 eject

Does not work with a SCSI internal ZIP drive (nor with an
external parallel-port drive accessed through vp interface).

>Fix:
It looks like the code might be cut/pasted from scsi_cd.c to scsi_da.c.
I don't know enough about the code to be sure; might be necessary
to check and do this only for removable drives.
