Your 'tape' is full.  It doesn't necessarily mean the disk
is full, it could be that your backups exceed your tape length.
Look farther down in your report for the taper line and see if it
wrote as many bytes as you specified for the length in your tapetype.
If so, either increase your tape length (since you're really writing
to a file instead of to a tape) or increase runtapes to write to
multiple 'tapes'.

I'm guessing you're not using a holding disk.  While it's not as
necessary using the file driver, it would allow multiple dumps to
occur in parallel, which can shorten your backup window (using a
different disk is recommended to lessen I/O contention)
