One method to determine if a problem is with Oracle or the MML  (Media
Management Layer,
such as Veritas for Oracle ) is to use the dummy tape interface.

Oracle provides a 'tape' libray that actually writes to disk.  It exercises
the
RMAN API that MMLs are written to, allowing you to determine if a problem
lies with Oracle or somewhere else.

Here is an example of allocating a tape channel using the dummy tape
library:

allocate channel t01 type sbt  parms 'BLKSIZE=1048576,SBT_LIBRARY=
oracle.disksbt,ENV=(BACKUP_DIR=/bkup_1/orcl)'

There is at least one MetaLink note that includes this.
