ORA-15097: cannot SHUTDOWN ASM instance with connected RDBMS instance

What triggered the Error:

A SHUTDOWN command was issued to an ASM instance that had one or more connected RDBMS instances.

What should we do to fix it:

Connect to each RDBMS instance and shut it down, and then reissue the SHUTDOWN command to the ASM instance. Alternatively, use the SHUTDOWN ABORT command. Note that issuing the SHUTDOWN ABORT command to an ASM instance results in abormal termination of all RDBMS instances connected to that ASM instance.
