This is a script I wrote to show the status of all Exchange 2010 DAG databases. It displays to the EMS console color coded to see db's running off of Activation Preference location. And it will handle any size DAG.
#
# .\Status-DAG-DB-Locations.ps1
#
# Function:
#
# Status and display the current database preference of the Active mailbox database of the Database Availablity Group specified.
#
# Sample:
#
# .\Status-DAG-DB-Locations.ps1 <DAGName>
# i.e.: .\Status-DAG-DB-Locations.ps1 <default = DAG that this server is a member of>
#
# The script will parse through the databases on the Database Availablity Group displaying the "active" location and Activation Preference.
#
# Assumptions:
#
# Displays the current Active Database and the Activation Preference sequence number based on the mailbox database activation Preference settings.
#
#
