The Nutanix auto-inventory update flow resulted in the deletion of vmk# on all the ESXi hosts within the cluster.

Products

• VMware vSphere ESXi
• VMware vCenter Server

Issue/Introduction

• VMK#(eg. vmk1) got deleted on Nutanix environment on few or all the hosts.
• vmk# connected networks lost network connectivity.

 

Environment

VMWare vSphere ESXi
VMWare vCenter Server

Cause

• Following an LCM (Life Cycle Manager) framework update via auto-inventory, the vmk# on ESXi hosts was deleted.
• This occurs because the LCM logic incorrectly identifies vmk1 as a BMC-dedicated port and removes it as part of the standard auto-inventory update workflow in Nutanix environment.
• This creates a conflict when vmk# is utilized for the internal virtual Nutanix vswitch eg. vSwitchNutanix.

Resolution

This issue impacts Nutanix Clusters with DELL hardware.
