How to: Pause or Resume a Database Mirroring Session (SQL Server Management Studio)
To pause or resume a database mirroring session use the Database Properties Mirroring page.
Following a forced service, when the original principal server reconnects mirroring is suspended. Resuming mirroring in this situation could possibly cause data loss on the original principal server. For information about managing the potential data loss, see Forced Service (with Possible Data Loss).
