Question about HA Issue

[winshenting]

After enable HA setting in the HA, there is configuration issues showing " Insufficient resources to satsify HA failover level on cluster", BTW, in one of the host, there is also configuration issues showing "HA agent disabled". I try diable HA and enable HA, no working. Try reconfigure for VMware HA, not working either.

What shall I do?

How many node do you have (only 2)?

How is configured the "Allow VMs to be powered on even if they violate availability constraints" box?

There are a few reasons for this,

How many hosts are in your cluster?

is your host the is showing HA Agent Disabled correctly licensed?

I have only two hosts in my cluster. The setting of Admission control is as below,

Number of host failures the cluster can tolerate 1

Prevent VMs from being powered on if they violate availability contraints.

It is not the license issue. The configuration issue is " HA agent disable in cluster" only

[Troy_Clavell]

if you set to allow VM's to power on even if the violate availability constraints, that error will go away. The reason it's there because your HA Failover Capacity probably cannot support all of the VM's if one of your ESX Hosts goes down.

Here is a good article on how HA Failover Capacity is calculated.

You have the KB Andre Linked which is good as well.

[Troy_Clavell]

One other thing you may try, create a new cluster, enable HA and DRS, then disconnect and remove your Hosts fromt their current cluster and add them into the other. This will prompt the HA agent to be installed again.

If you haven't tried that on your existing cluster, you may want to try that too.

After enabling " allow VM's to be powered on even if they violate availabitlity constraints", the issue has been solved now temporarily. Thanks very much
