4 For distributed deployments with load balancers, disable each secondary node and remove the
vRealize Automation health monitors for the following items.
a vRealize Automation appliance
b IaaS Website
c IaaS Manager Service
Verify that load balancer traffic is directed only to the primary nodes and that the vRealize Automation
health monitors are removed for the appliance, Website, and Manager Service, otherwise the
upgrade fails.
5 Verify that the IaaS service hosted in Microsoft Internet Information Services (IIS) is running by
performing the following steps.
a In your browser, go to the URL https://webhostname/Repository/Data/MetaModel.svc to
verify that the Web Repository is running. If successful, no errors are returned and you see a list
of models in XML format.
b Check the status recorded in the Repository.log file on the Web node of the IaaS virtual
machine to see that status reports OK. The file is located in the VCAC home folder
at /Server/Model Manager Web/Logs/Repository.log.
For a distributed IaaS Website, log in to the secondary Website, without MMD, and stop the
Microsoft IIS server temporarily. Check the MetaModel.svc connectivity. To verify that the load
balancer traffic is going through only the primary Web node, start the Microsoft IIS server.
