Connecting primary and secondary instances of PI to SAP MII using SAP PCo

Hi,

I am using SAP NetWeaver CE 7.1 EHP1 SP05 and SAP MII 12.2 SP03 patch 6. The Plant Connectivity software is SAP PCo 2.2.

We are connecting to PI ( PI software version is 3.4.375.99) .

We have a Primary and Secondary instances in PI. I want MII to connect to secondary instance once primary goes down.

Kindly let me know what are the settings i need to do from the SAP PCo side or SAP MII side so as to achive this scenario.

Kind Regards

Suhas
