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