Following is a report ( long, sorry ) of the dump I made after compiling
this morning, and folowing that - the real problem - restore dosen't
recognize the dump !!!

We should have 8 volumes on tape, i.e.;
=======================================
vol 1 = + /sbin/dump 0dsbfu 57440 13000 96 styx:/dev/rmt/1mbn /
vol 2 = + /sbin/dump 0dsbfu 57440 13000 96 styx:/dev/rmt/1mbn /usr
vol 3 = + /sbin/dump 0dsbfu 57440 13000 96 styx:/dev/rmt/1mbn /export
vol 4 = + /sbin/dump 0dsbfu 57440 13000 96 styx:/dev/rmt/1mbn /opt
vol 5 = + /sbin/dump 0dsbfu 57440 13000 96 styx:/dev/rmt/1mbn /win-files-1
vol 6 = + /sbin/dump 0dsbfu 57440 13000 96 styx:/dev/rmt/1mbn
/home/ftp/pub
vol 7 = + /sbin/dump 0dsbfu 57440 13000 96 styx:/dev/rmt/1mbn
/home/ftp/pub/microsoft
vol 8 = + /sbin/dump 0dsbfu 57440 13000 96 styx:/dev/rmt/1mbn
/home/ftp/pub/linux
Now, the crux of the problem, Linux dosen't recognize the dump
=======================================
# restore -ifs styx:/dev/rmt/1 6
s: No such file or directory
# restore -if styx:/dev/rmt/1
read: I/O error
tape read error: Unknown error -1
Neither does Sun;
