看了SqlServer主体在镜像服务器宕机后的日志:
Bypassing recovery for database 'BOS2015_Empty' because it is marked as an inaccessible database mirroring database. A problem exists with the mirroring session. The session either lacks a quorum or the communications links are broken because of problems with links, endpoint configuration, or permissions (for the server account or security certificate). To gain access to the database, figure out what has changed in the session configuration and undo the change.
有大神能说下一这是什么情况吗
