Tape Volume full with UtilPct in 0% and status filling

Hi!
I have a TSM v3.1 on AS/400, and i'm having this problem, seems like the
tape volume is full, but is in a filling state with a util percentil of 0%,
and is imposible to be full, someone of you have any idea how to solve
this, also do you know where i can get what means a CPFxxxx?:
