Environment

VMware vCenter Server 6.0.x

Cause

This issue occurs when the vCenter Server's host operating system (OS) has more than one IPv4 address assigned to a single physical or virtual NIC.

Resolution

This issue is resolved in vCenter Server 6.0 Express Patch 01. 

Workaround:
To work around this issue, remove additional IPv4 addresses from the NICs on the vCenter Server's Host operating system and perform the upgrade again.

Note: Ensure that you only have a single IPv4 address per NIC on the vCenter Server's Host OS.
