I just ordered an HP 20GB 'travan like' drive. It'll be interesting to see
if this is also that broken.
And this is with the unit there *and* a tape inserted? Wow! That is
*really* fantastically broken that a tape drive that has a tape inserted
supports *neither* a load (to BOT) command or a REWIND. The load is
optional. The rewind is mandatory. That's amazing.
I think I'll have to invent a new quirk for someething this broken.
The code that this is breaking on is the following in samount:
/*
* *Very* first off, make sure we're loaded to BOT.
*/
scsi_load_unload(&ccb->csio, 2, sadone, MSG_SIMPLE_Q_TAG, FALSE,
FALSE, FALSE, 1, SSD_FULL_SIZE, 60000);
error = cam_periph_runccb(ccb, saerror, 0, SF_QUIET_IR,
&softc->device_stats);
if ((ccb->ccb_h.status & CAM_DEV_QFRZN) != 0)
cam_release_devq(ccb->ccb_h.path, 0, 0, 0, FALSE);
/*
* In case this doesn't work, do a REWIND instead
*/
if (error) {
scsi_rewind(&ccb->csio, 5, sadone, MSG_SIMPLE_Q_TAG,
FALSE, SSD_FULL_SIZE,
(SA_REWIND_TIMEOUT) * 60 * 1000);
error = cam_periph_runccb(ccb, saerror, 0, 0,
&softc->device_stats);
}
if (error) {
xpt_release_ccb(ccb);
goto exit;
}
When you're trying to mount a tape, make sure you're at BOT. If the
rewind is failing- it's hard for me to really be sure I'm not overwriting
something I shouldn't be, but if this drive really is that busted, I'll
guss I'll quirk it so it doesn't matter.
