Use Case :
One comment: If you had used WFA to create the SnapMirror policies, your "backup then mirror" workflow would have seen them without any refreshes. This is due to the reservation feature of WFA.
But to answer you question, currently there is no supported OCUM6 API to refresh the clusters on-demand. Also, you cannot change the discovery interval from the default value of 15 minutes.
Neelesh is correct. That said, the API and capability IS being added into OC UM 6.1, so this capability should be available soon.
