Name is any alphanumeric string.
You can create a mirror member called an async member, which can be configured to receive updates from one or more mirrors across the enterprise. This allows a single node to act as a comprehensive enterprise-wide data warehouse. Async members do not belong to a mirror and, therefore, are not candidates for failover.
For more information, see the Async Mirror Members section of the “Mirroring” chapter in High Availability Guide
Changing This Parameter
You can change AsyncMemberGUID in the Config.MirrorMemberOpens in a new window class (as described in the class reference) or by editing the CPF in a text editor (as described in the Editing the Active CPF section of the “Introduction to the Configuration Parameter File” chapter in this book).
