Hi there
I was wondering if there is anyway I can add a host with running vm's into a EVC cluster, is there any cheat around the restrictions in the kb below. what if I created a new non EVC cluster, added the hosts then enabled EVC? I wont be able to reboot machines immediatley to take advantage of the new EVC mode.
Cannot add an ESX/ESXi host with running virtual machines to an EVC enabled Cluster (1009571)
Resolution
An EVC enabled Cluster cannot determine the CPU Compatibility features used by any of the running virtual machines. A host has to be put in maintenance mode before it can be added to the EVC cluster.
To place the ESX host into maintenance mode:
- vMotion the running virtual machines from the standalone host to the hosts already in the cluster.
- When all of the machines are finished migrating, place the ESX host into maintenance mode.
- Add the host to the cluster.
OR
- Power down all of the running virtual machines on the ESX host.
- Place the host into maintenance mode.
- Add the host to the cluster.
If vCenter Server is a virtual machine:
- Power down virtual machines on host B.
- Add host B to EVC Cluster.
- Perform one of these options:
- Power down the vCenter Server virtual machine on host A.
Or
- Unregister the vCenter Serever virtual machine using the vSphere Client connection directly to host A.
- Connect to host B via vSphere Client, register the vCenter virtual machine and power on.
- Power down all remaining virtual machines on host A and add to EVC Cluster
