VCP7-CMA – Objective 3.4

Disclaimer: These are my notes from taking the 2V0-731 exam. If something doesn’t make sense, please feel free to reach out.

The goal of this objective is to understand basic troubleshooting.

Objective 3.4 – Troubleshoot Common vRealize Automation Installation & Configuration Errors

• Perform a rollback installation on a minimal or enterprise deployment
  • Revert to pre-installation snapshots if available
• Generate a vRealize Automation support bundle
• Validate DNS configuration settings
• Confirm time synchronisation
• Confirm machine certificates
• Validate credentials used to configure endpoints

• Installing vRealize Automation

Rollback installation at a high level:

• Uninstall any components from add/remove programs on the IaaS server
• Revert database to pre-installation state
• Remove HTTPS binding from website
• Check that these sites and app pools have gone:
  • Repository
  • WAPI
  • Vcac

Alternatively, you should be able to revert to the snapshots you took during the installation, you are prompted to take them 🙂

Support bundle is generated from the vRA appliance management interface, from Admin, Logs. There is a ‘Save Log Files’ button. This is jus the logs for the appliance you are logged into.

For the cluster logs – vRA Settings, Cluster, ‘Create Support Bundle’ button.

I believe the time piece this is referring to is on the same page. You have a list of hosts and the time offset between them. Once you hit an offset of 600 seconds or more you’ll start running into problems. In reality if NTP is working they shouldn’t be more than 5-7 seconds apart.
