Hi all,
I would like to thank Kevin Davidson for his prompt reply to my request.
I am enclosing with this mail his reply, as it worked just fine.
I think this question should be somewhere in the Solaris FAQ.
IT is very basic, but all administrators who are used to SunOS
will stumble upon this kind of problem.
This is my original query:

An here's Kevin's reply:
Use the device /dev/rmt/0hbn instead. The system V tape driver leaves
the tape head just *before* the end of file marker. Your next dump
overwrites the end of file marker, effectively extending the first
file instead of writing a new one. ufsrestore etc don't expect any
more data after they've read the first set of data, so they fail to
read any more.
Using the BSD compatible device leaves the tape head *after* the EOF
mark, so writing your next dump writes a new file.
I don't understand why the system V device works the way it does. It
doesn't seem to be useful for anything.
