Reading Unix System V R4.2 Data on 3M DC 6150 Catridge Tape

Posted on 2006-05-24

I have a Fujitsu Super Server running on Unix System V Release 4.2 whose drive has crashed. I have data that has been backed up on 3M DC 6150 data catridge tape (150 MB capacity). I would like read this data and try to recreate my system. How can I do so?
Can I just attach the catridge drive to another System V R4.2 machine? If so, where can I get a System V R4.2 software?

    This is from wikipedia: "Release 5 was released as SCO UnixWare 7 by SCO. SCO's successor, The SCO Group also based SCO OpenServer 6 on SVR5, but the codebase is not used by any other manufacturer."

    And according to a quick Google, the Fujitsu box is old - a Pentium 133 ort Pentium Pro class box.

    You have something of a problem...

    If your server was running a specific application, then I'd check with the manufacturer to see if there is a later update that might run under, say, Linux, and what conversions will have to be done. If the server was providing more generic services then you may be in luck. You could try loading Linux (Red Hat Enterprise Linux or SuSe - SuSe seems more popular in Europe, whilst Red Hat is generally pretty well known) to a new server, transfer the tape drive hardware then use tar to read the tape.

    SCO's Unixware 7 ( is a development of System V - so you may be in luck and your application *may* run under the latest Unixware 7. I'd check with SCO ( and the application manufacturer. I'd be inclined to use Unixware 7 as a platform to migrate to Linux or Solaris. You may be aware that SCO sued a number of Linux developers (IBM amongst them) over alleged patent infringements. I have no idea if the case is still running, and if so, who's currently winning, but personally (and please note, this only *my* opinion, not that of EE yadda yadda), I'd have some concerns about the longevity (and therefore supportability) of SCO's Unix offerings.

    It is probably dump format as that was the standard used in the dump.hd script. As far as getting a copy of SCO 3.2v4.2 SCO may send you the floppies but they always wanted a photocopy of the original floppy before supplying replacement media when I used to support it. You can use OpenBSD instead, dump format is the same -
