This issue occurs because the dvfilter module is not getting loaded.

  1. Run this command to load the dvfilter module:
    #esxcfg-module –e /usr/lib/vmware/vmkmod/dvfilter
  2. In the ESX host, navigate to Configuration > Software and click Advanced Settings.
  3. Remove the IP address from /Net/Net.DVFilterBindIpAddress.
  4. Reboot the ESX host.
