  1. What is the process to update DAG members ? • When you install an update rollup on a server that's a member of a DAG, several services are stopped during the installation, including all Exchange services and the Cluster service. The general process for applying update rollups to a DAG member is as follows: • Use the StartDagServerMaintenance.ps1 script to put the DAG member in maintenance mode. • Install the update rollup. • Use the StopDagServerMaintenance.ps1 script to take the DAG member out of maintenance mode and put it back into production. • Use the RedistributeActiveDatabases.ps1 script to rebalance the active database copies across the DAG. • Source : http://technet.microsoft.com/en-us/library/dd298065.aspx#In
