StartDagServerMaintenance.ps1 Error with 2 Database Copies

When you have a DAG with only two nodes, the StartDagServerMaintenance.ps1 script is smart enough to recognize that you can't have 2 additional copies of the database. However, if you have more than 2 DAG members, then the script complains that it can't run because the local database copy is required for redundancy.

I ran into this at a client where we created a database in the DR site for running test cmdlets with SCOM. There are two copies of the database in the DR site. Other databases have two copies in the main site and one copy in the DR site.

You can override the default behaviour with the switch OverrideMinimumTwoCopies.

Example:

StartDagServerMaintenance.ps1 -Server DAGnode1 -OverrideMinimumTwoCopies
