So yesterday, i had finished with distributed installation of vRA 7.3. I configured tenants, fabric, business groups and created a base blueprint for testing purpose. All was breeze and was working fine. So today i decided to go with failure testing scenarios.
I brought down my Active IaaS Manager service node and hop into vRA console to see if everything is working fine. But alas, i started seeing logs that my Agent cannot connect to manager service. It is down and agent cannot connect to proxy.
Could not connect to the Manager Service. The service might be offline or restarting. If this error persists, verify the that ManagerService.exe is running and that the endpoint, https://<iaasname>/VMPS2Proxy, can be reached.
It turns out automatic failover of manager service was not enabled. So i enabled it, restarted manager service and voila its working again. To enable manager service, follow below steps:
- Log in as root to a console session on the vRealize Automation appliance.
- Navigate to the following directory. /usr/lib/vcac/tools/vami/commands
- Enter the following command.
python ./manager-service-automatic-failover ENABLE
