Issue/Introduction

• During VM vMotion between the hosts within the cluster, a warning was reported in the 'Select Networks' section

  • 'Currently connected network interface – Network adapter X is uses network 'DVSwitch[DVS-ID] NSX port group [dvportgroup-xxxxx] (NSX port group not found)', which is inaccessible

• This issue would report due to the unavailability of NSX segments/port groups at particular destination ESXi host/transport node within the cluster
