Anyone have any experiences installing and running this Seagate tape
drive off of an Adaptech AHA2940 SCSI controller on Linux 1.2.39?
Specifically its Seagate product # STD280000N.

I'd appreciate any and all input.  Thanks

Cheers,

I currently run the seagate 4x8 gig stacker dat drive with little
problems, however I never got it to work with an adaptec 2940.  I ended
up using a dec version of the ncr 53c810 and have had no trouble since.
My kernel is newer however.  I went to 2.0.33 and the latest adaptec
driver patches.  From what I could tell, my problems were that the 2940
also ran the hard disks in the pc.  The dec scsi card now only does the
tape drive.  OTH I have had no trouble using disks and tape off of other
brand scsi cards.

I can't help you with this specific problem but your hardware may be a
little high-end for this group.

Suggest you:

 - Test the stacker under another OS (commercial Unix, none of the PC
OSs I know of -- Win3x/95/NT, OS/2, Mac) has real tape support), if you
can.  Find out if it works and with what SCSI adapter.

 - Find out from Seagate what the rated SCSI card(s) is/are.

 - Post to a general hardware or Unix discussion.  You'll find units
like this on Solaris and HP boxen, you might go knocking there.

 - Check the SCSI HOWTO for the latest driver info and bugs.  There's
some fairly detailed info in there if you dig for it.  There may be new
or alpha/beta drivers around.   Contact the developer(s) of the
promising/obvious ones.

 - Try digging around Boardwatch magazine's archives
(http://www.boardwatch.com/) -- they're an ISP industry mag, or on the
ISP related NGs (if they exist).  Those guys have backup issues to deal
with and may be familiar w/ your HW.

AFAIK, once you've got a supported SCSI card, all devices should work
off of it -- disk, tape, removable media, scanners, sewing machines,...
I may be wrong (and frequently am).

Good luck.

1. Seagate TapeStor 8GB SCSI tape drive question

Hi,

I'm running RedHat 5.2 (kernel 2.0.36) and just installed a Seagate
TapeStor internal SCSI tape drive onto it. The drive uses Travan TR-4
tapes with 4GB native and 8GB hardware-compressed capacity. Linux has
found it and reading/writing the drive seems fine. However, I have a few
questions. Since the tape drive uses hardware compression to achieve 8GB
capacity, do I have perform any setup to turn this compression on? Is
this compression on by default by the hardware? How can I find out
whether compression is being used?

Thanks a lot.
