When maintaining an environment or network, you might need to assign a different IP address to an existing vRealize Automation appliance.

Prerequisites

  • As a precaution, take snapshots of vRealize Automation appliances and IaaS servers.

  • From a console session as root on the vRealize Automation appliances, inspect entries in the /etc/hosts file.

    Look for address assignments that might conflict with the new IP address plan, and make changes as needed.

    On all IaaS servers, repeat the process for the Windows\system32\drivers\etc\hosts file.

  • Shut down all vRealize Automation appliances.

  • Stop all vRealize Automation services on IaaS servers.

Procedure

  1. In vSphere, locate the vRealize Automation appliance that you want to change, and select Actions > Edit Settings.
  2. Click vApp Options.
  3. Expand IP allocation, and enable the OVF environment option.
  4. Expand OVF Settings, and enable the ISO image option.

  14. Wait for DNS replication and zone distribution to occur.
  15. Start all vRealize Automation appliances.
  16. Start vRealize Automation services on IaaS servers.
