have you checked your cluster logs? system logs? does it always happen? have you investigated a bit by yourself?

Which release?

Is your TEMP tablespace made of temporary files? If so, why do you even backup the TEMP tablespace? You don't have to, there is no point in backing up tempfiles.

In general HA software (Sun HA or Veritas) periodically uses sqlplus to login into database and inserts/updates a table with in certain period of time. If the execution takes longer time, then the HA thinks some thing wrong in the database connection, so it failover to other node.
Check up your hot backup script one more time. And ensure that you did not put the DB under restricted mode.
