This is for SCOM 2007 R2 CU7.
I am working on a domain with 1000 servers, 300 belong to one group, and 700 to another. I have one RMS, MS and reporting server per group. They have seperate opsmanager DB's, but share a data warehouse.
1) They both need to use AD integration. From what I've seen, if i put all the servers in AD in different security groups, I can use the inclusion rule to target which servers go to which management group. This seems to only work if the servers are in one of the groups, but if a server isn't in any group, it just connects to whoever. I need a way of making sure servers from one group never connect to the other groups RMS. It's not practical to manually enter all the servers from one group into the exclusion rule of the other.
2)Also, some of the servers from one group are VM's that are completely rebuilt each weekend and use a script to install SCOM. If it is connected to one management group, then is reinstalled with all of the same info, will it just keep communicating with the RMS, or will the RMS know its a new instance with the same name and not accept communications?
3) If i manually install an agent on a server in group one and tell it to connect to a MS in group one, and that server goes down, will in be able to failover to the RMS, or will it only be able to talk to the MS.
