The sys.database_files catalog view does not allow querying a mirror database.
How is one to obtain info on the database files/locations of a mirror db?

Thank you! While I was googling, I also came across another view with similar output: sys.master_files.

Either one will do for me, thanks again!

sys.master_files is the 2005 and above equivalent of sysaltfiles. Expect sysaltfiles to be deprecated, so I recommend getting in the habit of using sys.master_files.

Thanks, I saw that, I'm using sys.master_files in my code.
