Could you point out how I shold test the > target mode?Thank you very much. > Ben 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. -matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
