fault tolerance not working

On one server "host already has the recommended 4 ft vms running on it...disable restriction in HA advanced options". On the other server "virtual machines in the same fault tolerance pair cannot be on same host" Some of the vms work other do not.Same shared storage, same processors etc. version 5.1

Check and see how many vCPU's on the VMs that are not working. Only 1 vCPU per VM is supported.

> "virtual machines in the same fault tolerance pair cannot be on same host"

This error is typically  an indication of FT failed to find compatible host in cluster to power on Secondary. It attempts to power on Secondary VM on all compatible hosts in cluster including where Primary VM is running. Attempt to power on Secondary VM on same host as Primary VM fails with above mentioned error. Please check FT configuration on all hosts. FT readiness is also displayed on Host summary page.
