we are using SCOM2007R2 with the nWorks management-pack.
recently, we have updated the nworks manpack from version 5.6 to 6.0. the update did work fine.
after the update, we have added a new vmware server in the veeam virtualization extension web gui. this worked also fine and the new ESX hosts and performance /hardware data were listed in SCOM.
one week later, there was a newer verison of the management pack available (6.5). we decided to run this update from verison 6.0 to 6.5.
unfortunately after the update scom is not able to collect hardware data / status and performance data from the esx hosts an VMs. and adding new esx hosts to monitor doesnt work too.
we have tried to rebuild the topology and re-run the configure health tasks. no success

any ideas?
thank you for some inputs.
