Hi

I've deployed a Nutanix Cluster AHV in a dark site. Im having the issue exactly described here:

https://next.nutanix.com/installation-configuration-23/prism-central-stuck-at-76-vm-is-not-reachable-42437?tid=42437&fid=23
 

But the topic was closed without any solution so I have to search for it… In summary:

After deploying the cluster I tried to deploy the Prism Central with no luck, it got stucked at 76%...

  • AOS 7.3.1 + PC 7.3.1

  • The PC VM intially startas and answer by ping, however it is automaticaly restarted during the config process and it loses the net config so it gets unaccesible by lan

  • When checking the Prism Element tasks, I see the Application Deployment task stuck atl 76 %.

  • If I open the PC VM console to check its status I can see that it stuck on the OS boot and I can see several services such as auditd, ntpdrsyslogrc.localhowever it doesnt show the login prompt.

  • If I manualy boot the VM it boots normaly (it shows the login prompt), but there is no lan configuration

  • If I try to enter by console using admin or nutanix users with default pass: nutanix/4u o Nutanix/4u it doesnt work (bad credentials)

  • If I do nothing there is atime out (it tooks about 1h to fail)

  • I’ve conected to the CVM and manualy deleted the prism central VM to try a next attempt with no luck, it also stops at 76%...

The fact Im deploying dark mode site, does it has something to be with this issue?

Any help is apreciated!

Thanks

It was a switch issue. The customer has configured LACP on the ports of the switch. As soon as he configured Access mode on the ports it worked fine...
