VMware Infrastructure Navigator or vRealize Infrastructure Navigator as its now called, is a very light weight and very simple to use and rarely has an issue. but occasionally like everything problems come up. like “access failed. an unknown VM access error has occurred” generally its easier to just redeploy but here is a tip you can redeploy without redeploying with a couple of simple commands.
1) log onto the VIN server as root
2) run the command :
monit stop vadm-engine
This will stop the VIN service
3) execute the file
This will drop the VIN database
4) execute the file
This will re configure the database
5) run the command:
monit start vadm-engine
This will start the VIN service.
The appliance should then start preparing the environment.
Another good command to run is
monit summary this will show the service status.
