Nutanix nodes do not have any IP address information on them when initially shipped to a customers site. To run the configuration process, Nutanix uses IPv6 link-local to configure the nodes. If the configuration page does not come up, you can use these steps to troubleshoot a possible IPv6 issue.
Connect two Windows, Linux, or Apple laptops to the switch to be used.
Disable any firewalls on the laptops.
Verify that each laptop has an IPv6 link-local address.
Windows (Control Panel)
Start > Control Panel > View network status and tasks > Change adapter settings > Local Area Connection >Details
Note the IPv6 link-local addresses, which always begin with fe80. Omit the / character and anything following.
From one of the laptops, ping the other laptop.
> ping -6 ipv6_linklocal_addr%interface
$ ping6 ipv6_linklocal_addr%interface
Replace ipv6_linklocal_addr with the IPv6 link-local address of the other laptop.
Replace interface with the interface identifier on the other laptop (for example, 12 for Windows, eth0 for Linux, or en0for Mac OS).
If the ping packets are answered by the remote host, IPv6 link-local is enabled on the subnet. If the ping packets are not answered, ensure that firewalls are disabled on both laptops and try again before concluding that IPv6 link-local is not enabled.
Reenable the firewalls on the laptops and disconnect them from the network.
If IPv6 link-local is enabled on the subnet, you can use automated IP address and cluster configuration utility.
If IPv6 link-local is not enabled on the subnet, you have to manually create the cluster by following Configuring the Cluster (Manual), which includes manually setting IP addresses.
