Cancelling a job does not free the storage that the job occupied before it 
was cancelled.

Also, there is no way to remove / overwrite the data that a single job wrote 
to a volume. But the whole volume can be overwritten, if wanted. So, the 
question here is, if the tape already had something valuable written into it 
before the job that got canceled.

If everything in the volume in question may be discarded, have a look at 
"purge volume" command. But be warned, it ignores any retention times, and 
is not limited to certain jobs. Basically, purge operates with the catalog 
only, but after the volume is purged (references to its content are removed 
from the catalog), it may be recycled, and at this point the volume (tape) 
will be used again.
