rman 11r1 backup after converting standby to primary

Hi, I've converted a standby to primary.   It will be the primary going forward.

I am not using an rman catalog (client's choice)

These are the incarnations

DB Key  Inc Key DB Name  DB ID            STATUS  Reset SCN  Reset Time

When I try to backup the database, it seems to be backing up what used to be the standby database and because the directory structures have changed, it doesn't back up anything.   I thought I could just register all the incarnations available and re-register the database but I'm not using a catalog.   All the new backup locations and other backup attributes have been updated using the 'CONFIGURE' command but they don't appear to be read because of the incarnation that is at play.
