Advertise here with BSA I was going over some of the VMTN threads and I noticed an issue brought up with Admission Control a while ago. Fewer Available Slots Shown Than Expected The Advanced Runtime Info box might display a smaller number of available slots in the. With the slot policy option, vSphere HA admission control ensures that a specified number of hosts can fail and sufficient resources remain in the cluster to fail over all the virtual machines from those hosts. 5. vSphere Cluster HA provides high availability for virtual machines by pooling the virtual machines and the hosts they reside on into a cluster. The first place I would look is in the cluster setting for HA. This combination can result in a more balanced cluster after vSphere HA has moved virtual machines to different hosts. vSphere HA powers down the VMs. While removing hosts, I get down to 4 hosts and it starts complaining with "Insufficient resources to satisfy vSphere HA failover level on cluster XXX in XXX". ThanksWhen you edit a DRS affinity rule, you must use vSphere HA advanced options to enforce the desired failover behavior for vSphere HA. If restart is not possible, for example, the failover ESXi hosts have insufficient resources or have failed as well, then vSphere HA attempts to restart the virtual machines on other ESXi hosts in the cluster.
