DRS gives no suggestions

[ranjitcool]

I have two hosts in my infrastructure.

I moved all machines to host 1 and had the DRS to partially automated and then fully automated,

when I click on run drs, it always says completed. Does not give me suggestions, or nothing.

It won't even move the machines and balance load.

I checked events tab - no errors or issues.

What am i missing?

Thanks

have you considered the possibility that the ESXi Host that is running all the VM's is supplying enough resources so that DRS thinks the cluster is balanced? If you highlight your cluster and look to the right under VMware DRS, is the load balanced?

What is the migration threshold set to?

Thanks for the reply Troy,

Yes it says load balanced even when I move all the machines to just one host. Both hosts have 32GB RAM, and my vms take only about half of that at any given time. Technically one host can take the entire load and run with it as CPU consumption is low as well.

Right now Load is balanced

Migration Threshold says  - Apply priority 1, priority 2 and priority 3 recommendations.

What could it be?

[Troy_Clavell]

as far as DRS is concerned you have no problems.  You can manually balance the load if you'd like, or maybe try sliding the bar for your migration threshold all the way to aggressive.

Bottom line is if the Host can provide the resources to the VM's then DRS has done it's job.

Thanks for the advice, i made it aggressive and DRS kicked in right away.

I think I already started to forget what priority 1,2, 3 and 4 meant.

As one host can handle all VMs, there is no need for DRS to make any recomendations.

You could in theory reduce the load to one physical host and then start thinking about using the DPM features to power the second host only in the event of the first being under too much load.

If you're working for a 'green' company, you'll get brownie points . . if not . . you'll lose one ESX host ;-)

Don't worry though . . VMs have a habit of sprawling . .soon everyone and his dog at your company will want a VM and you'll be adding hosts to your cluster to help balance the load.

If you would like to just simluate load to invoke DRS, you can get a tool from : http://msdn.microsoft.com/en-us/magazine/cc163613.aspx

I am yet to use DPM, i did set it up but it didnt do any magical turn off stuff. I hope we get more vms and more hosts, i like staying busy as a bee :smileygrin:
