A customer is running 2.0.7 and has a SCSI HP DATA tape drive.
(HP C1533A DDS-2) and would like to back up to it.  Anybody know if
this will work?  Also is there a TAPE HOW TO somewhere out there?
Thanks in advance:  =Mike

Hi Mike,

I have the same drive connected to a BusLogic BT946, and it works like
a charm (fast too :-). The SCSI-HOWTO has a section on tapes which is
worth reading.

Please mail me if you have any further questions.

Regards,
Julian

This will work perfectly!  I have the exact same tape backup drive.  Just make
sure that it is supported by the SCSI card.  To do a backup command you must
initilize it first with 'mt -f /dev/st0 erase' and then backup with 'tar cvf
/dev/st0 /' and restore with 'tar xvf /dev/st0 /'  There are some other tricks
just to get a file listing with tar, just issue the same command to untar but
specify a file list only.

-Hope this helps.

Ok.  I got my new tape drive and it seems to work a little bit.  I can
tar to the drive *once* and recover anything from that single tar, but
any successive tar's simply overwrite the first one.  I did:
mt setblk 262144                (it said invalid size so I tried 8092)

tar c a*                        (this works)
tar t                           (returns a*)
tar c b*                        (works)
tar t                           (returns b*)
tar A c*                        (works)
tar t                           (returns b* followed by:
                        tar: Skipping to next file header...
                        tar: only read XXXX bytes from archive /dev/rmt0  )

mt b* never works - /dev/tape b* 1 failed: I/O error.
mt f* seems to work - no errors, but nothing happens either.
mt erase hangs the drive.
mt rewind worked once but doesn't seem to do anything anymore.
mt offline works(ejects the tape)
...
I've tried ALL the commands and can't get it to work.  Am I missing
something obvious here?  Is it that I simply don't know how to use tar or
mt?  Is there something quirky about my drive(told the dude I bought it
from it would be used with Linux and he said no problems).

At this point, I just want to be able to back up stuff.  I'm on a 200 Meg
HD(lost my other one :() and am desperate to free up some space.  I have
a 4 Gig Tape Drive and while I can use it, I can't use it like I'd expect
I should be able to use it :).  Any help in resolving this would be
appreciated.
