8 Log in as root to a console session on the master vRealize Automation appliance, and run the
following script.
/usr/lib/vcac/tools/change-hostname/change-hostname.sh old-master-FQDN new-
master-FQDN
9 Log in as root to a console session on all replica vRealize Automation appliances, and run the
following command.
sed -i "s/old-master-FQDN/new-master-FQDN/g" "/etc/haproxy/conf.d/10-psql.cfg"
"/etc/haproxy/conf.d/20-vcac.cfg"
10 Log in as root to the master vRealize Automation appliance management interface.
https://vrealize-automation-appliance-FQDN:5480
11 Click the vRA Settings tab.
12 Below the tabs, click Messaging.
13 To reconfigure the messaging services with the new name on all nodes, click Reset RabbitMQ
Cluster.
14 Restart the master vRealize Automation appliance.
15 Restart all replica vRealize Automation appliances, one at a time.
16 If the old master vRealize Automation appliance host name was used in a certificate, update the
certificate with the new name.
For information about updating certificates, see Managing vRealize Automation.
17 If the old master vRealize Automation appliance host name was used with a load balancer in an HA
environment, check and reconfigure the load balancer with the new name.
18 Verify that all authentication connectors are working correctly.
19 In DNS, remove the existing DNS record with the old master host name.
Change a Replica vRealize Automation Appliance Host Name
When maintaining an environment or network, you might need to assign a different host name to an
existing replica vRealize Automation appliance.
In a high availability cluster of vRealize Automation appliances, follow these steps to change the host
name of a replica vRealize Automation appliance node.
Prerequisites
If the master node host name needs to change, complete that entire procedure first. See Change the
Master vRealize Automation Appliance Host Name.
Procedure
1 In DNS, create an additional record with the new replica host name.
Do not remove the existing DNS record with the old host name yet.
