Environment
VMware vSphere Storage Appliance 5.5.x
Cause
The vSphere Storage Appliance (VSA) 5.5 installer attempts to configure itself to use Enhanced vMotion Compatibility (EVC). However, EVC mode on a host cannot be changed when there are running virtual machines (VMs) on that host.
Resolution
To work around this issue and to allow vSphere Storage Appliance (VSA) operations to complete, configure VSA not to use Enhanced vMotion Compatibility (EVC). This ensures that VSA does not attempt to configure EVC in your Distributed Resource Scheduler (DRS) cluster.
To configure VSA not to use EVC:
- Open a remote console or RDP session to the Windows server on which the VSA Manager is installed.
- Open the %programfiles%\VMware\Infrastructure\tomcat\webapps\VSAManager\WEB-INF\classes\dev.properties file using a text editor.
- Locate the line having the configuration variable evc.config and modify its value from true to false.
- Restart the VMware VirtualCenter Management Web services. For more information, see Stopping, starting, or restarting VMware vCenter Server services (1003895).
