FYI - I was only able to get the multiple concurrent backup streams to work by 
inserting a 10 minute "sleep" between each startup.
Thanks,

Hi,

        It should be fine to run the parallel backup on different databases 
that are not on the same LUN/volumes.
        For your problem, RC 418 means TSM API error, please check dsmerror.log 
under baclient directory to see if there is any error messages. Also you can 
contact support for help.

Best regards.
Tian Miao Liu
