Exchange 2010 DAG Maintance

When you need to performing maintenance on DAG nodes here is the process you want to go through In my environment I have two nodes in a dag. For more nodes the same process
All the commands below are run in an administrative prompt.

Type add first: cd $exscripts and press enter.

Now you are in the Exchange Scripts .

When you are finished on Node 2

When done performing maintenance on one or multiple servers (hopefully one at a time to maintain full database availability for end users!) you can end up with a sub-optimal active database layout, especially if you have a cross-site DAG. To resolve this you have to rebalance the databases based on the priorities set for them upon creation.
Rebalance databases across dag

If you get any errors you may have to re-index the search catalog for the passive database. Rather than hunting down which ones need to be fixed you can just fix them all with the custom I wrote below (or for only the mail servers with ). When finished running these commands then try to run the maintenance or rebalance scripts again.
