VMware HA or VMotion problem

Lackey11 · ‎10-12-2010

Vsphere 4.1 with two IBM Host running esxi embedded 4.0 upgraded to 4.1

IBM m2 3550 24gb of ram 3 vm on second host and 1 vm on first host

I have setup two host to talk to my SAN server which contains my VMDK files.

I am trying to setup HA/vmotion however i am experiencing some problems and i am not sure where to focus on.

so the situation is that when i reboot one host that contains a running VM it will actually reboot before it switch over to the other host and then it starts up again on the second host.

error msg: Insufficient resources to satisfy HA failover level on cluster

I've review a lot of articles regarding that error msg however nothing that i've tried resolved my problem.

tried to break the cluster and reconfig as well as i went thru this article which contains 15 points withno solution.

thank you.

>Insufficient resources to satisfy HA failover level on cluster

That is your problem. If your other host in the cluster cannot provide the necessary resources for the other guests of which their host failed, HA will not fail them over. As a test you can disable admission control, or get yourself another ESX Host.

A couple things worth reading

Hi,

That is the normal behavior of VMware HA. When a host fails or is rebooted (or powered off), all the VMs will be restarted on another host available on HA Cluster. HA doesn't use vMotion.

The error message "error msg: Insufficient resources to satisfy HA failover level on cluster", is absolutely normal when a host is not available in a HA Cluster with 2 hosts.

thanks for clearing this up for me. maybe I am trying to do something and getting mixed up with the technology here..

what I am really trying to do is setup my enivornment to the point when one host with VM goes down or lose network connection, the VM will automatically switch over to the secondary host. I got to the point where i can migrate live VMs between host however when i down one host the VM goes down with it.

Hi,

VMware HA always reboots the VMs when a failure event happens. The only VMware feature than may help is Fault Tolerance, but it has some limitations and is recommended just for critical VMs.
