I am backing up a database with R

[cajunrob]

I am backing up a database with Rman to disk and tape.

When I back up to disk I set up the snapshot controlfile name to the directory to which I am backing up.
configure snapshot controlfile name to '/oracle/u04/bxdev4/rman_backup/scontrolf';
It accepts this no problem.


I am having trouble setting the name when backing up to tape. When I try to set the name to something like this
configure snapshot controlfile name to 'bxdev4_scontrolf';

It reject it and goes back to default.

What should I set it to when backing up to tape?

Thanks
