While doing the usual vRA 6.2.2 large deployment distributed install, and after everything in the installation went smoothly without any errors, the vRA infrastructure tab was not working. Checking the vRA Services through the vRA Appliance VAMI, and noticed all of my services are up and running as expected with its status being registered, beside the iaas-service which its status was left blank. Look at the below screenshot and notice where the service column ” iaas-service com.vmware.csp.iaas.blueprint.service” status being blank.
Going through every test I can think of, I could find no meaningful error in any of the logs, till I opened my infrastructure tab again but in Chrome this time and rather than getting the usual 404 error it was giving me earlier the below message came up: Invalid Argument. Host name may not be null
After a bit of digging/research, I have found out that the VIP names the customer is using included under scores which is not supported by vRA for both hostnames or VIP names. This has been documented in the vRA 6.2 Installation and configuration document here as well in KB2086553.
Resolution for this issue: You will need to avoid this scenario before hand, else you will have to redo the full installation. I posted this in here to help you avoid it. By the way, the hyphen works just fine, its just the underscore that you need to avoid, so you can use it as an alternative.
