Check with ioscan -nfCtape and after verify the write in tape with tar cv file.

with error number 5 (I/O error) See /usr/include/sys/errno.h

It is a write error, due to a flaw on the media or media has finished, other cause are posible too.

To fix the cause run xstm ( or stm) and get status for this device, whitout unload the tape.
