Issue/Introduction

While installing ESXI 8, we are getting the following error naa.######################: disk device does not support OSDATA" 
Error Message : 

Environment

VMware vSphere ESXi 8.x

Cause

ESXi 8.0 requires a boot disk of at least 32 GB of persistent storage such as HDD, SSD, or NVMe. A boot device must not be shared between ESXi hosts.
