Cluster partition details not showing drives on SNMP OpMan7

Cluster partition details not showing drives on SNMP OpMan7

We have 2 x clustered servers. 2 x servers will not show the cluster drives, only the local drives on SNMP therefore I cannot monitor partition wise % details for these servers. Even if I add the cluster nodes individually the drives do not show on the active node. Also to monitor SQL instances on the virtual IP of the 2 clusters, the monitors show N/A on the main device page even though the data is being collected as I can see through looking at the graph for example of data file sizes. Is this as bug with MS Clustering? This worked fine on Version 6
Please help
