vRealize Automation 7.1 Wizard Install – vCenter Agent Name not aligned with IaaS Host

Looks like there maybe a bug in the vRA 7.1 wizard deployment. I’m running vRA version  7.1 build 4270058 and Windows 2012 R2 build 9600.

Installing vRealize Automation 7.1

This post will provide a step-by-step walk through installation of vRA 7.1, utilising the vRA wizard based install and configuration utility.

This example focuses on the ‘Enterprise Install’ for a distributed, highly-available vRA instance, using the wizard-driven walk through for the installation. The wizard helps to drive such tasks as importing the user generated certificates, creates your vRA SQL database and automatically fixes any issues on the IaaS Windows machines encountered during validation, for example removing MS patches that impede the install or fix IIS related configurations.

This post does not cover pre-requisite tasks such as:

  • Deploying the vRA appliance.
  • Provisioning & joining domain for the required Windows 2012r2 servers detailed on the infrastructure list below, SQL|Web|DEM|Agent machines.

  • DNS entries for all the components including virtual IP addresses.
  • Ensuring NTP & time is correct across all related components.
  • IaaS associated user accounts.
