i have checked the permission on /dev/st0

crw-rw---- 1 root disk 9, 0 Apr 26 14:44 st0

which permission should i look at?

Any ideas are welcome.

The MaxDB runs under a special user (sdb), since only the user root and the members of the group disk may write to that device it's clear that this error occurs.

The easiest way to fix this is to put the user sdb (if you use the default user) into the group 'disk'.
