Below are the steps necessary to stop monitoring a cluster that will be decommissioned and is currently being monitored with System Center Operations Manager 2007. If you do not follow this procedure, there is a risk that you may have orphaned virtual servers after the cluster is decommissioned.
In order to remove monitoring of the cluster, perform the following steps:
1. Remove the Operations Manager agent from all nodes of the cluster being decommissioned.
2. Ensure that all of the cluster nodes (including the virtual cluster nodes) are no longer visible in the Operations Manager console by checking the Agent Managed and Agentless Managed views under the Administration section of the Operations Manager console.
3. Proceed with decommissioning the cluster.
Hope this helps,

i would add: best practice for ideal case.
there dozens unsupported ways to remove cluster from monitoring if we forgot to uninstall agents.
is MS planning to publish official article and making these unofficial ways official ones?
in step 1, i assume by "remove agent" you mean "remove it manually from add/remove programs
since you can't uninstall from the scom console because the agent is managing other agents.
but removing the agent manually from the cluster node still doesn't remove it from the scom console it just greys it out in the agent-managed list. and all the cluster resources are stil in the agentless list.
what am i don't wrong? it's scom 2007 R2 CU5 and this still doesn't work for me.
