Use ESXi firewall disable instead of unload

Products

• VMware vSphere ESXi

Issue/Introduction

 

• Host NOT responding during few operations like vSAN cluster leave and EAM uninstalling.

Cause

• Services like vSAN, EAM requires ESXi firewall to be in loaded state. if customer explicitly unloads the ESXi firewall for some reason then it may lead to host not responding / disconnection during vSAN destroy.
   

Resolution

To workaround the issue, disable the ESXi firewall using the command below instead of unloading the firewall:
#esxcli network firewall set --enabled false
