B,E

Here's the an additional reference

The sbtio.log contains information written by the media management software, not Oracle Database. Thus, you must consult your media vendor documentation to interpret the error codes and messages. If no information is written to the sbtio.log, then contact your media manager support to ask whether they are writing error messages in some other location, or whether there are steps you must take to have the media manager errors appear in sbtio.log.

Read the messages from the bottom up, because this is the order in which RMAN issues the messages. The last one or two errors displayed in the stack are often the most informative.
