When maintaining an environment or network, you might need to assign a different IP address to an existing vRealize Automation IaaS Windows server.
If the vRealize Automation appliance IP address needs to change, do that first. See Change the vRealize Automation Appliance IP Address.
As a precaution, take snapshots of vRealize Automation appliances and IaaS servers.
From a console session as root on the vRealize Automation appliance, 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 the vRealize Automation appliance.
Stop all vRealize Automation services on IaaS servers.
- Log in to the IaaS server with an account that has administrator rights.
- In Windows, change the IP address.
Look for the IP address in the Windows network adapter settings, under Internet Protocol properties.
- Refresh your local DNS with the changes.
Refreshing DNS ensures that the IaaS Windows servers can find each other and that you can reconnect to a Windows server if you are disconnected.
- On the Manager Service host, inspect the following file in a text editor.
The default install folder is C:\Program Files (x86)\VMware.
Verify IP addresses or FQDNs of vRealize Automation appliances and IaaS Windows servers.
- On all IaaS Windows servers, inspect the following file in a text editor.
Verify the IP address or FQDN of the vRealize Automation appliance.
- Log in to the SQL Server host.
- Verify that the repository address is correctly configured to use FQDN in the ConnectionString column.
For example, open SQL Management Studio and run the following query.
"SELECT Name, ConnectionString FROM [database-name].[DynamicOps.RepositoryModel].[Models]"
- Start the vRealize Automation appliance.
- Start vRealize Automation services on IaaS servers.
- Inspect log files to verify that Agent, DEM Worker, Manager Service, and Web host services started successfully.
- Log in to vRealize Automation as a user with the Infrastructure Administrator role.
- Navigate to and verify that all services are running.
- Test for correct operation by checking appliance services, testing provisioning, or using the vRealize Production Test tool.
