I deploy a 3 nodes cluster with ESXi 7.0 as the hypervisor successfully on AOS 5.15.3.
But when I run the diagnostic.py to check the cluster performance. It always failed to boot the diagnostic VM. I tried 3 times and all is same. from the log, seems the CVM cannot reache the diagnostic VM when check the boot status.
I login to vCenter and check that there is no IP address for this VM in the summary page. And I can login the diagnostic VM from the VM console, I can check the ip address which is 192.168.5.253, but I cannot ping 192.168.5.254 and 192.168.5.1. also cannot ping 192.168.5.253 from CVM.
From this information, I think the CVM cannot reache the diagnostic VM and timeout, so the diagnostic.py will fail after timeout.
Is there any idear for this test? I can run thie script successfully in ESXi 6.7.

We recommend using XRay instead of diagnostic.py script to our customers. The script is deprecated hence why it works on a later ESXi but not on the recent one – was not validated.
X-Ray is an automated testing framework and benchmarking application for enterprise-grade datacenters. The X-Ray application is a downloadable virtual machine (VM) with a user interface and complete documentation. Once installed, X-Ray can test and analyze several different systems and report comparable information for your use.
