Hello!



This is my environment:



LENOVO Converged HX3710 Appliance - Type 8689 (4 Nodes)

AOS 5.10.5

Foundation VM 4.4

ESXi 6.5 U2



I am trying to install nutanix AOS 5.10.5 on this LENOVO HX server without any success so far. The installation process fails once again with the following message:



------------------------------------------------------------------------------------------------------------

20190623 14:29:56 ERROR Error occured during virtual media mount: Session no longer connected

20190623 14:50:05 WARNING The target is not ssh-able or not in phoenix



------------------------------------------------------------------------------------------------------------



It looks like that the CVM can't establish a SSH connection through port 22.



And so far I have done the following without any success:



1. Turn off the antivirus in the LAPTOP where the VM Foundation is running.

2. Turn off the firewall in the LAPTOP where the VM Foundation is running.

3. Increase the SSH TIMEOUT on every node of the LENOVO HX server.



Please help me on this.



Thanks
We are getting same error in the fresh installation in Nutanix 3306-G6 with 3 node server. Installation could ready the IPMIs of the 3 nodes. But when the nodes are waiting to boot into phoenix, this may take 20 minutes, it was unable. The log shared here:

Now we are planning to replace/clear configuring the switch and try with new getting started.

Will update you.
If the Pheonix is not installed or booted properly, foundation can not connect to CVM. In this situation the mentioned error occurs and foundation can not complete the installation. Do:


  1. Upload the Nutanix AHV Metadata successfully
  2. Upload the Nutanix AHV successfully
  3. Select the AHV uploaded file, not the AOS bundle while Foundation is asking for AHV image
Now try...! I hope this will work as it worked for me.

This maybe due to the hypervisor version is not supported by Foundation to install onto the hardware. Just check again the compatibility between hardware and hypervisor

Just check the connection whether you are using 10Gbps interfaces and IMM port of Lenovo servers or not.

The best way is plug in a monitor and to see what happen when Foundation checking is there any uplink available for installation
