Provide the most common errors during the deployment of Cloud Automation appliances and how to identify them.
Prerequisite infrastructure services may be misconfigured or encountering an issue.Note: This includes the configuration of the proxy appliances deployment as it relates to these infrastructure services. Be sure to check both external configurations and appliance configurations.
NTP, DNS, and Shortname sections should be reviewed and are suggested for all proxy variations: Cloud Automation Appliances for VMware Aria AutomationVMware Aria OrchestratorCloud ProxyVMware Aria Extensibility Proxy (formerly vRealize Automation Extensibility Proxy)Cloud Extensibility Proxy Step 1: NTP issues Validate the Server IP and hostnameValidate connectivity to the NTP server.Validate the port is opened.Delete the VMs of the failed attempt and retry the deployment. Step 2: DNS issues Validate that the DNS server is reachable and that the port is opened.The DNS record must use Fully Qualified Domain Names (FQDNs), no shortname.A Single A record and a Single PTR record is required. CNAMEs are not supported (only Multitenancy supports CNAME records, for more information refer to this document Set up multi-organization tenancy for VMware Aria AutomationRetry validation of the forward and reverse lookup using the nslookup FQDN and nslookup IPaddress command. Validating lookup for Name resolutionNote: Fully Qualified Domain Names are required. Do not use shortnames. There should be a single A record for each appliance and VIP. root@appliance [ ~ ]# nslookup <vra.example.com> Server: 192.168.xx.xx Address: 192.168.xx.xx#53 Name: <vra.example.com> Address: 192.168.20.xxx Validating the reserve lookup Note: There should be a single PTR record, CNAMEs are not supported (with the exception of Multitenant environments), and if the record is duplicated it causes issues. root@appliance [ ~ ]# nslookup 192.168.20.xxx xxx.20.168.192.in-addr.arpa name = <vra.example.com> VMware Aria Automation/VMware Aria Automation Orchestrator 8.7 and later use the dig command instead of host in order to validate the DNS service in the script /opt/health/Makefile "single-aptr" Version 8.6.2 single-aptr: eth0-ip $(begin_check) echo Check the ip address if eth0 resolves only to a single hostname [ 1 -eq $$( host $$( host $$( iface-ip eth0 ) | wc -l ) ] $(end_check) Version 8.7 onwards single-aptr: eth0-ip $(begin_check) echo Check the ip address if eth0 resolves only to a single hostname [ 1 -eq $$(/usr/bin/dig +noall +answer -x $$( iface-ip eth0 ) | grep "PTR" | wc - l ) ] $(end_check) Therefore, for these versions it is recommended to run the following commands: /usr/bin/dig +noall +answer +nocookie -x $( iface-ip eth0 ) /usr/bin/dig +noall +answer +noedns -x $( iface-ip eth0 ) /usr/bin/dig +noall +answer -x $( iface-ip eth0 ) Scenarios: If the answers are blank, it is required to create a PTR record. If only the last command succeeds and a Microsoft AD DNS server is being used, please review this Microsoft Article Some DNS name queries are unsuccessful after you deploy a Windows-based DNS server. After fixing any DNS issues, delete the VMs of the failed attempt, and retry the deployment. Step 3: Shortname issues Delete the VMs of the failed attempt and retry the deployment using FQDNs. If a shortname was used within the DNS record configuration, update the DNS records before retrying the deployment. Step 4: Additional validations for Cloud Extensibility Proxy and Cloud Proxy Once Steps 1-3 through are complete, consider the following: OTK expires in 24 hours.OTK cannot be reused for several proxies.Validate there is internet connectivity.The OVA must be deployed to a vCenter. Deployment directly to an ESXi server is NOT supported.For the cloud proxy, a network proxy that performs TLS terminations is NOT supported.Run the following command to validate there is connectivity to the required URLs: sh /data-collector-status –-traceroute Note: The URL required can change based in proxy location as explained in: Download and deploy a cloud extensibility proxyAdd a cloud proxy to a vCenter in Automation Assembler Step 5: Additional validation for VMware Aria Automation Orchestrator (formerly known as VMware vRealize Orchestrator) Please check the following article: After deploying VMware Aria Automation Orchestrator (formerly known vRealize Orchestrator) the UI spins and never loads. Step 6: Network Load Balancer For cluster (3 nodes) deployments deploy a Load Balancer: VMware Aria Automation Load Balancing Guide. This is a strict requirement, except for the following products: VMware Aria Automation with VMware Aria Lifecycle in VCF mode.VMware Aria Operations with VMware Aria Lifecycle in VCF mode.VMware Identity Manager with VMware Aria Lifecycle in VCF mode. Note: VMware Aria Automation Orchestrator (formerly vRealize Orchestrator) will require manual creation of the load balancer.
