Retrieves database mirroring configuration and status for mirrored databases and their witness servers
This command collects detailed mirroring information from databases configured with SQL Server Database Mirroring, including partner servers, witness servers, safety levels, and synchronization status. It queries both the database properties and the sys.database_mirroring_witnesses system view to provide complete mirroring topology details. Use this when you need to audit your mirroring setup, troubleshoot mirroring issues, or verify mirroring configuration across multiple instances without manually checking each database's mirroring properties in SSMS.

Pipeline | false |
Default Value |
By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
