You need the drivers

device scsi_target
device scsi_targ_bh

in your kernel as well as enabling target mode support in either the
Adaptec driver or the the QLogic driver. Note that while the QLogic
driver supports simultaneous initiator/target mode operation, the last
I checked, the Adaptec doesn't, so for your h/w, you have to have the
initiator side *not* have AHC_TMODE_ENABLE on. You might probably want
to put

device pt

in the initiator side.

Once you boot the target mode side, you'll eee wildcard enabling
via the targbh driver so that commands to non-existent luns have
somebody to actually respond.

Then go off and compile /usr/share/examples/scsi_target/scsi_target.c
and enable a lun for real.

Then boot the initiator side or camcontrol rescan the initiator side.
