To manually create a cluster after the nodes have been successfully imaged but the automated cluster creation fails, the correct command to use is:

cluster create -s IP_CVM_A, IP_CVM_B, IP_CVM_n

This command specifies the -s option to include the IP addresses of the Controller Virtual Machines (CVMs) on the nodes, initiating the manual cluster creation process.

When deploying Nutanix hardware, it is essential to ensure that all necessary components are included in the Bill of Materials (BOM). In this case, the BOM includes SFP+ modules but lacks the fiber cables needed for connectivity. The SFP+ modules indicate a requirement for fiber optic cables, and it's crucial for the consultant to ensure the client understands their responsibility to procure compatible cables. Nutanix typically does not provide fiber cables as these are considered network infrastructure components, which vary based on specific network requirements and setups.References:

Given the reported RX errors on eth2 and the intermittent ping loss as observed from the CVM logs, the best initial troubleshooting step that avoids VM disruption is to inspect the switch port for errors. Option C, "Check the port on the switch side for any errors," is the most direct and non-invasive approach to determining if the issue lies with the network infrastructure rather than the server hardware itself or the configuration.

This action helps identify whether the problem is related to the physical connection (e.g., port issues, switch configuration errors) without altering the current active network setup on the Nutanix node. If errors are found on the switch port, adjustments or repairs can be made accordingly, potentially resolving the RX errors without impacting the running VMs.
