Traditionally into vsphere environment we are having a concept of LUN to provide storage into ESXi into which VMware administrator used to provision virtual machine into that peace of storage (LUN). In this process all vm’s which are deployed are depended into that LUN having dependency into it. Like, if that LUN having any issue like all path went down or its loosed its connectivity from ESXi or storage, into this case all its derivative vm’s will get affected. That dependency has moved out into VVol VVol has introduced where virtual machine is directly connected to SAN (Raw area of storage), not on LUN concept.  Architecture of VVol In Virtual Volumes storage has altogether changes compared to old architecture of Vsphere.

What I found is its VMkernal switch got removed due to unexpected reason. So to resolve the issue I tried to reconfigure its vswitch0 (vmk0) by going into Tech Mode of that Exi. Below are the steps which I followed to resolve the issue. 1) Login to ESXi 2) Press F2, Check if you " Configure Management network " is greyed out or not" if yes,    follow below 3) Press ALT+F1 to move the ESXi screen to tech mode   ( This is command line like dos) 4) login with root account 5) Run the following command into it esxcli network ip interface add --interface-name= vmk0
