Quite often the tape drive appears to 'hang' and will not respond to eject requests either from the button (does nothing - no LEDs flash etc) or mt -f /dev/ast0 offline (returns EIO) A reinit of the channel gets the tape drive back in order, ie atacontrol reinit ata0 How-To-Repeat: The script to write to the tape is fairly straightforward. It tar's a bunch of stuff to a spool directory then writes those files out to tape, rewind's the tape and then reads the files back and compares md5. As compared to SCSI drives (AIT, DDS & LTO) I have had to add delays into the script to wait for the tape to rewind as it does not appear to block until it's done. It does not report EBUSY when you try and access it. This is unfortunate as there is no way to tell if the drive is busy, broken, has no tape, etc..
State Changed From-To: open->feedback Daniel, is this still a problem on the RELENG_7 platform? I'm guessing it is, but confirmation of such would be worthwhile. FWIW, I also have personal interest in this PR, as I'm considering purchasing one of these drives for home use. Reassigning to sos@, since this is his department.
