Missing Mirrored Database

Hi guys

I've added a new mirrored failover member to an existing one.

They are both Arbiter controlled.

When I do Add database to mirror on the primary I'm always getting an error. Missing Mirrored database.

I followed everything in the documentation and always get the same error.

I've copied the CACHE.dat file after umounting the database on both servers. then mounted them.

Could you help me out?


Kind Regards

You have to set your DB to be in Primary MIRROR before the copy.
Otherwise, you may miss some kind of "Mirror-Marker" / Timestamp. 

I hit this trap also on my first trials.
