This post covers Re-balancing (Redistributing) Microsoft Exchange databases in a Database Availability Group (DAG) by Activation Preference using Microsoft Exchange PowerShell.
I have just recently patched my Server and also updated Servers in my Microsoft Exchange 2010 environment to SP3 RU6. To avoid any mail interruptions i had moved databases around and now that i am done i need to re-balance (redistribute) database by database activation preference.
Enjoy
Syntax for running the script:
.\RedistributeActiveDatabases.ps1 -DagName <DAGName> -<How to redistribute>
Example:
.\RedistributeActiveDatabases.ps1 -DagName 001-NAEX14-00 -BalanceDbsByActivationPreference
