Easy Scale fails at Connect to vCenter step when scaling a node into an EVC-enabled HCI cluster

Applies to

  • HCI 1.6 with EVC scale patch
  • HCI 1.7 with EVC scale patch
  • HCI 1.8 or newer without EVC scale patch
  • EVC enabled in ESX
  • CVE-2018-3646 vulnerabilities have been patched on nodes in the cluster
  • VSS in use on the ESX cluster
