I have a 3 SQL servers(2008 R2 SP2 Enterprise) on a four node Cluster (2008 R2 SP1 Enterprise)
These are protected by two DPM Servers 1 and 2.
DPM2 was the master protection server, backing up all databases all servers and also backing DPM1 system state, BMR and DPM SQL Server, plus all volumes as well.
DPM1 provides protection for all Protection groups on DP2 and also backing DPM2 system state, BMR and DPM SQL Server, plus all volumes as well.
DPM1 is Local to SQL Servers
DPM2 is on the end of a WAN.
I want to switch back to DPM1 and relieve stress on the WAN.
So....
- I removed all protection groups from DPM2 deleting all the data.
- I detached all nodes from DPM2
- I ran setdpmserver on each cluster node and attched them to DPM1
- I created new protection groups on DPM1 for databases.
This is were the problems started with (unable to create recovery point) and when creating PG's I had error messages about these items are protected by anther server.
does anybody know the correct procedure for doing this ?
