Hi If we have more than Two DAG Members, We must have at least Three Healthy Database copies. So while running the StartDagServerMaintenance.ps1, CheckDatabaseRedundancy.ps1 will find at least Two Database Copies in Healthy and Report will in GREEN State For more detail, you can refer to Exchange 2010 SP1: StartDagServerMaintenance.ps1 fails when a server contains databases with a single copy. http://blogs.technet.com/b/timmcmic/archive/2011/07/25/exchange-2010-sp1-startdagservermaintenance-ps1-fails-when-a-server-contains-databases-with-a-single-copy.aspx And for script: Exchange 2010 Database Redundancy Check Script, please have a look at http://blogs.technet.com/b/exchange/archive/2010/05/20/3409984.aspx CheersZi Feng TechNet Community Support
