You can [manually]( http://msdn.microsoft.com/en-us/library/ms186348.aspx) fail over by right clicking on the database, choosing mirror, then click failover. You can also use an alter database command. ALTER DATABASE DB_NAME SET PARTNER FAILOVER If you are using asynchronous you need to change the safety as well. Check out this [link]( http://weblogs.sqlteam.com/tarad/archive/2008/05/04/60585.aspx)
