Hi all,
I have a problem with a TLZ09-DB DAT-drive that
will not rewind tapes correctly (but that otherwise
is working correctly).
I have received the following replies:
* try 'mt offline' instead of 'mt rewind' and
'mt unload'.
* mt defaults to rmt0, maybe you need rmt1.
* use uerf to check for errors
* check firmware
I do indeed need rmt1 instead of rmt0 but the strange thing is
that it doesn't seem to make any difference. When I use
mt -f /dev/nrmt1h offline
I get the following error
/dev/nrmt1h offline 1 failed : I/O error
but the drive did rewind and unload the tape. (btw the same happens
when I use 'mt offline' (and thus use /dev/nrmt0h)).
Checking /var/adm/messages I see the following:
old TLZ09:
Dec 29 09:28:09 struct5 vmunix: tz14 at scsi1 target 6 lun 0 (LID=4)
(DEC TLZ09 (C)DEC 0165)
new TLZ09:
Apr 28 16:48:32 struct5 vmunix: tz14 at scsi1 target 6 lun 0 (LID=4)
(DEC TLZ09 (C)DEC 03a5)
Does 0165 and 03a5 indicate firmware version? If not how can I check
which firmware version I have?
(and where would I check for the latest firmware for a DAT-drive?)
using dia I get the following error messages:

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I suppose I could ignore the error (since the drive now rewinds and
unloads
the tape) but somehow that doesn't feel right. So I hope someone can
help me find the problem...
