	I have a SCSI Archive 2150 that also works quite well with ISC, I
can use DC600 tapes for 125 meg or DC6150 (DC600xtd) tapes for 150 meg.  Now
are you saying that with the SCSI drivers that we use for ISC the new 6250
tapes will give us 250 megs with no other changes?  If I had any complaint
it would be the inability of any SCSI tape drive to do multiple tape
backups.  (ie.  file systems larger than 150 megs in a single CPIO pass
without breaking things down into subdirectories on that file system.)

So I should ask this question:

	Has anyone figured a way with a SCSI tape drive (Archive or Wangtek)
to do multiple tape backups with CPIO?  Say a file system that is 300 megs
that would take 2 tapes with cpio asking for another tape like it did with
the older Non-SCSI Wangtek tape drives (60 megs).  There just doesn't seem
to be any report from the driver to CPIO that the end of the medium has been
reached and just hangs.

Thanks for any light you folks can shed on these questions.
