do you use VM resource reservation ? the HA cluster fail over will check the reservation not the actual load on the cluster

ie your cuurent load is 42Gb RAM 3Ghz processor power but if your reservation is 120Gb and 40Ghz CPU the cluster will complaint that the 1 host HA has not enough resources.

You can configure vSphere HA to tolerate a specified number of host failures. With the Host Failures Cluster Tolerates admission control policy, vSphere HA 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. VMware HA Slot is the default admission control option prior to vSphere 6.5. Slot Size is defined as the memory and CPU resources that satisfy the reservation requirements for any powered-on virtual machines in the HA cluster.This article is just to cover how. Oct 06, 2009 HA Slot Size Information. October 6, 2009 Alan 11. If you think you know better then you can change the advanced configuration for VMware HA by following this guide. You can see how many slots are available for each cluster and also the CPU and Memory details: Please note that this information unfortunately is not in the 3.5 API so this. When you select the Host Failures Cluster Tolerates admission control policy, the Advanced Runtime Info link appears in the vSphere HA section of the cluster's Summary tab in the vSphere Client. Clicking this link displays information about the cluster, including the number of slots available to power on additional virtual machines in the cluster.

You can avoid this error by changing your HA cluster to percentage of cluster resources instead of host failure but you are better to scope this properly and check if you have enough free resources if you use reservation.

vSphere HA uses admission control to ensure that sufficient resources are reserved for virtual machine recovery when a host fails.

Admission control imposes constraints on resource usage. Any action that might violate these constraints is not permitted. Actions that might be disallowed include the following examples:

Powering on a virtual machine
Migrating a virtual machine
Increasing the CPU or memory reservation of a virtual machine

The basis for vSphere HA admission control is how many host failures your cluster is allowed to tolerate and still guarantee failover. The host failover capacity can be set in three ways:

Cluster resource percentage
Slot policy
Dedicated failover hosts

vSphere HA admission control can be disabled. However, without it you have no assurance that the expected number of virtual machines can be restarted after a failure. Do not permanently disable admission control.

Regardless of the admission control option chosen, a VM resource reduction threshold also exists. You use this setting to specify the percentage of resource degradation to tolerate, but it is not available unless vSphere DRS is enabled. https://cleverarmor.amebaownd.com/posts/17912652.

The resource reduction calculation is checked for both CPU and memory. It considers a virtual machine's reserved memory and memory overload to decide whether to permit it to power on, migrate, or have reservation changes. The actual memory consumed by the virtual machine is not considered in the calculation because the memory reservation does not always correlate with the actual memory usage of the virtual machine. If the actual usage is more than reserved memory, insufficient failover capacity is available, resulting in performance degradation on failover.

Setting a performance reduction threshold enables you to specify the occurrence of a configuration issue. For example:

The default value is 100%, which produces no warnings.
If you reduce the threshold to 0%, a warning is generated when cluster usage exceeds the available capacity.
If you reduce the threshold to 20%, the performance reduction that can be tolerated is calculated as performance reduction = current utilization * 20%. When the current usage minus the performance reduction exceeds the available capacity, a configuration notice is issued.
