Today I got an error when selecting the “VMware EVC” option in the Cluster Settings at my vCenter 4.0 host with multiple HP Blades with same CPU. Error message:

Method not found: ‘Vmomi.HostSystemArray EVCState.get_BadSoftwareHostsBlockingEVC()’

Solution:

This issue occurs when a system installed with vSphere 4.1 and you use vSphere 4.0 Client on that system to access vCenter Server 4.0.

To workaround this issue, install a vSphere 4.0 Client on a system on which you have not installed vSphere4.1 Client earlier and then update the EVC cluster using the vSphere 4.0 Client.
