About Automatic Manager Service Failover
You can configure the vRealize Automation IaaS Manager Service to automatically fail over to a backup if
the primary Manager Service stops.
Starting in vRealize Automation 7.3, you no longer need to manually start or stop the Manager Service on
each Windows server, to control which serves as primary or backup. Automatic Manager Service failover
is disabled by default when you upgrade IaaS with the Upgrade Shell Script or using the IaaS Installer
executable file.
When automatic failover is enabled, the Manager Service automatically starts on all Manager Service
hosts, including backups. The automatic failover feature allows the hosts to transparently monitor each
other and fail over when necessary, but the Windows service must be running on all hosts.
Note You are not required to use automatic failover. You may disable it and continue to manually start
and stop the Windows service to control which host serves as primary or backup. If you take the manual
failover approach, you must only start the service on one host at a time. With automatic failover disabled,
simultaneously running the service on multiple IaaS servers makes vRealize Automation unusable.
Do not attempt to selectively enable or disable automatic failover. Automatic failover must always be
synchronized as on or off, across every Manager Service host in an IaaS deployment.
Run Test Connection and Verify Upgraded Endpoints
Upgrading from vRealize Automation 7.3 or earlier to 7.4 makes changes to endpoints in the target
environment.
After you upgrade to vRealize Automation 7.4, you must use the Test Connection action for all
applicable endpoints. You might also need to make adjustments to some upgraded endpoints. For more
information, see Considerations When Working With Upgraded or Migrated Endpoints in Configuring
vRealize Automation.
The default security setting for upgraded or migrated endpoints is not to accept untrusted certificates.
After upgrading or migrating from an earlier vRealize Automation installation, if you were using untrusted
certificates you must perform the following steps for all vSphere and NSX endpoints to enable certificate
validation. Otherwise, the endpoint operations fail with certificate errors. For more information, see
VMware Knowledge Base articles Endpoint communication is broken after upgrade to vRA 7.3 (2150230)
at http://kb.vmware.com/kb/2150230 and How to download and install vCenter Server root certificates to
avoid Web Browser certificate warnings (2108294) at http://kb.vmware.com/kb/2108294.
1 After upgrade or migration, log in to the vRealize Automation vSphere agent machine and restart your
vSphere agents by using the Services tab.
Migration might not restart all agents, so manually restart them if needed.
2 Wait for at least one ping report to finish. It takes a minute or two for a ping report to finish.
3 When the vSphere agents have started data collection, log in to vRealize Automation as an IaaS
administrator.
