VMware vSphere ESXi
This issue occurs when the upgrade is performed using a default VMware Image on the ESXi host which has hardware specific custom Image installed. Custom Images from hardware vendors may contain additional device drivers which are not part of the VMware default Image.
To resolve this issue, perform the upgrade using a Hardware specific custom ISO.
To download the custom ISO specific to your ESXi hardware, kindly refer the "ESXi Downloads
" section of VMware vSphere downloads, VMware Converter, OEM custom images, patches and addons in the Broadcom Support Portal
For additional details related to upgrading ESXi hosts with customer image installed, refer Conditions for deploying and upgrading an ESXi host deployed using a custom image
