Configuring Additional Instances of the vRealize Automation Appliance
The system administrator can deploy multiple instances of the vRealize Automation appliance to ensure
redundancy in a high-availability environment.
For each vRealize Automation appliance, you must enable time synchronization and add the appliance to a
cluster. Conguration information based on seings for the initial (primary) vRealize Automation appliance
is added automatically when you add the appliance to the cluster.
If you install a distributed installation with load balancers for high availability and failover, notify the team
responsible for conguring your vRealize Automation environment. Your tenant administrators must
congure Directories Management for high availability when they congure the link to your Active
Directory.
Enable Time Synchronization on the vRealize Automation Appliance
Clocks on the vRealize Automation appliance server and Windows servers must be synchronized to ensure
a successful installation.
If you see certicate warnings during this process, continue past them to nish the installation.
Prerequisites
“Congure the Primary vRealize Automation Appliance,” on page 68.
Procedure
1 Open a Web browser to the vRealize Automation appliance management interface URL.
2 Log in with the user name root and the password you specied when the appliance was deployed.
3 Select Admin > Time .
4 Select an option from the Time Sync Mode menu.
Option Action
Use Time Server
Select Use Time Server from the Time Sync Mode menu to use Network
Time Protocol . For each time server that you are using, enter the IP
address or the host name in the Time Server text box.
Use Host Time
Select Use Host Time from the Time Sync Mode menu to use
VMware Tools time synchronization. You must congure the connections
to Network Time Protocol servers before you can use VMware Tools time
synchronization.
5 Click Save .
6 Verify that the value in Current Time is correct.
You can change the time zone as required from the Time Zone Seing page on the System tab.
Add Another vRealize Automation Appliance to the Cluster
For high availability, distributed installations can use a load balancer in front of a cluster of vRealize
Automation appliance nodes.
You use the management console on the new vRealize Automation appliance to join it to an existing cluster
of one or more appliances. The join operation copies conguration information to the new appliance that
you are adding, including certicate, SSO, licensing, database, and messaging information.
You must add appliances to a cluster one at a time and not in parallel.
