As per Microsoft documentation for SCOM 2019 DR - The SCOM MS can be deployed to secondary DR on Standby recovery, by removing them from resource pool and disabling MMA, Data Access and configuration service.
Question : So, basically we need to fist install Management Servers on DR site as part of same Management Group and then remove them from resource pool and disable service. Is this correct understanding ? Will this not generate errors while group calculation as MS in DR are down ?
Also, as per documents
"Reconfigure the Windows agents to cache only management servers in your primary data center that should manage them to prevent them from attempting to failover to a management server in the secondary data center, which would only delay recovery and reporting. This can be accomplished if you manually deploy the agent in an automated manner with a script (for example, VBScript or better yet, PowerShell) to pre-configure during installation, or post deployment if you push the agent from the console, again using a scripted method managed with your enterprise configuration management solution.
Question : How we can achieve this and configure agents for not to contact MS in DR and How to enable them to connect to DR when situation arrives or testing DR setup
