You need to point to the existing one. You only have one operations database and one data warehouse per management group.

This is one of the problems with your particular failover scenario. If your RMS hardware dies, your database is also gone for the duration. All-in-one installations on a single server will always give you a single point of failure. The ideal way to setup for redundancy/failover is to host your SQL databases separately on their own SQL cluster/s.
No matter which way you go about it, you will need your encryption key to get your "new" RMS promoted so make sure it is backed up using the securestoragebackup.exe tool and stored somewhere you can get at it in an emergency.
