Hi Chuck: It works! Great job! Thanks! Best regards, Jerry Lee Senior Engineer Broadband & Storage Wistron Corp.

The setup I tested with was similar (WinXP initiator and targ(4)). It appears that Windows sends a REPORT LUNS command which scsi_target doesn't support. In turn, the unsupported command causes scsi_target to abort. Here is a partial patch of the changes I made (this is against 4.9). Note that the CVS logs for scsi_target make some reference to a fix for REPORT LUNS, but I haven't looked into it at all. ---chuck --- ../st_49/scsi_cmds.c Tue Feb 18 14:07:10 2003 +++ scsi_cmds.c Tue Jan 20 12:40:31 2004 @@ -143,11 +143,14 @@ } if (last_cmd->cmd == ILLEGAL_CDB) { if (event != ATIO_WORK) { - warnx("no done func for %#x???", a_descr->cdb[0]); - abort(); + warnx("cdb %#x not handled (evt=%d)", a_descr->cdb[0], + event); + free_ccb((union ccb *)ctio); + return (1); } /* Not found, return illegal request */ - warnx("cdb %#x not handled", a_descr->cdb[0]); + if (debug) + warnx("cdb %#x not handled (evt=%d)", a_descr->cdb[0], event); tcmd_illegal_req(atio, ctio); send_ccb((union ccb *)ctio, /*priority*/1); return (0); @@ -245,12 +248,11 @@ /* Fill out the supplied CTIO */ if (ctio != NULL) { - /* No autosense yet bcopy(sense, &ctio->sense_data, sizeof(*sense)); - ctio->sense_len = sizeof(*sense); XXX - */ + ctio->sense_len = sizeof(*sense); + ctio->ccb_h.flags &= ~CAM_DIR_MASK; - ctio->ccb_h.flags |= CAM_DIR_NONE | /* CAM_SEND_SENSE | */ + ctio->ccb_h.flags |= CAM_DIR_NONE | CAM_SEND_SENSE | CAM_SEND_STATUS; ctio->dxfer_len = 0; ctio->scsi_status = SCSI_STATUS_CHECK_COND; @@ -313,6 +315,10 @@ } else { bcopy(&inq_data, ctio->data_ptr, sizeof(inq_data)); ctio->dxfer_len = inq_data.additional_length + 4; + + /* calculate the residual */ + ctio->resid = ctio->dxfer_len - SCSI_CDB6_LEN(inq->length); + ctio->dxfer_len = min(ctio->dxfer_len, On Wed, Feb 18, 2004 at 08:17:43PM -0500, jerry_ch_lee@wistron.com.tw wrote: > > > > Hi: > > Did anyone have such experience? > My setup is: > > Initiator: PC with Windows 2000, LSI Ultra320 SCSI card > Target: PC with FreeBSD 5.2, on-board Adaptec 7899W chip > command on target: > ./scsi_target 0:1:0 file > > When I rescan hardware on initiator, the Target's scsi_target program > exit > itself. > Then I re-run scsi_target program again, and rescan hardware on > initiator, > then... > > Target crashed!
