Hello,

Well, the test command is failing on a fsf command (forward space file). Th=
is=20
means that there is something incorrectly set in the tape driver.  Since yo=
u=20
have an IBM system, it is possible that they have put your drive in SysV mo=
de=20
rather than BSD mode.  Bacula works only in BSD mode, which is the default=
=20
for Linux.  Please see the Tape Testing chapter of the manual for details o=
n=20
verifying and setting the mode.

Regards,

Kern
