tar is not always a good transport between flavors of unix.  I have used Unisys SVR4 in the past and if you were to use the the cpio command that is native to the Unisys SVR4 unix along with a GNU cpio executable on the linux side you should be able to port your data files.  From the root use the following syntax:

     # find ./data_directory -depth -print | cpio -ocv -C10240 -O/dev/rmt0

If you don't want the whole directory you may first want to create a file list with the find command and dump it to a file:

     # find ./data_directory -depth -print > /tmp/file_list

Then edit the file /tmp/file_list and remove all the file names that DO NOT want.  Once this has been done issue the following:

     # cat /tmp/filelist | cpio -ocv -C10240 -O/dev/rmt0

Next find a GNU cpio executable to load on your linux box then restore the tape.  The native linux cpio command may even work so give it a try.

Not sure right off the top of my head what the linux or GNU switches would all be but from root may be something like:

     # cpio -icdmuv -I/dev/tape_device_name

          - or -

     # cpio -icdmuv < /dev/tape_device_name

Now the problems you are having on the linux side may be that you need to configure the tape drive into the kernel before you can read in the tapes.

Hope that helps.

Diskette spanning has never worked real well for me, maybe others have had success.  As fo the linux not starting is that before or after adding the viper tape drive?  If it is after, make sure you don't have a SCSI ID conflict going on.  One should be able to pick a decent used viper drive or compatible at a reasonable price somewhere.  Otherwise if you have a DAT drive you could put that into the U6000 (so long as it is 8GB or less) at the proper SCSI ID then go back to the linix box for the restore.  Another option if you have networking installed on both machines would be to do an ftp transfer from U6000 to linux.

Good luck.

Would you be able to provide the exact model and hardware configuration of both your U6000 and linux machine?  Would need to know the brand, model numbers and ID's of all your SCSI devices and what brand and model of SCSI Host Adapter is being used on the linux side.

If the tape drive is working on the U6000 and all the SCSI rules are being followed, there is no reason why the linux system should not start.  Now it could be that your linux box is using the newest SCSI technology which could be an issue.  If that is the case then you may need to add an older SCSI adapter like an Adaptec 2940au or 1542CF or something similar to your linux box and have the tape drive be the only device on that adapter.

Let us know what you have in the two boxes and we should be to come up with a combination that would work for you.

Good Luck.
