HA option to restart VM on specific Host

Hi ,

Does anyone know if it's possible to specify in a HA environment a affinity between VM and Host?

We want to do a HA environment between two site (Prod and DRP) but we want that all VM which running on Prod site are migrate between all Prod Host until no ressources will be available in this site and migrate to DRP site if necessary.

I hope that you understand me.

Thanks.

You can't specify which hosts a VM will fail onto during an HA event.

HA will take the first host available (alphabetically) in the cluster to use during a failure.

Hi,

Yes, we know that HA use this feature but we see on other topics that HA (ESX3.0.1)verify ressources available on all Host and use the host with more available ressources (without using DRS).

If HA used only alphabetically feature, we could make our environment using a correct naming of ESX prod and DRP but we want to be sure that VM will not be migrate to the DRP site if ressources are available in Prod site.

I think that vmware should reflect has this option because it would be very useful for different envirronements.

Thanks for your informations.

das.defaultfailoverhost:

If this is set, VMware HA will first try to fail over hosts to the host

specified by this option. This is useful if you want to utilize one

host as a spare failover host, but is not usually recommended,

because VMware HA tries to utilize all available spare capacity

among all hosts in the cluster.

If the specified host does not have enough spare capacity,

VMware HA tries to fail over the virtual machine to any other

host in the cluster that has enough capacity.
