Changing the host for a virtual machine on a cluster and Host is not in complaince with the attached profile

[Tikitiboo201110]

Hi all,

I have 02 questions.

1. We have a cluster which has 02 physical hosts (Host1 and Host2). On the Cluster we have 02 virtual machines. DRS enabled on the cluster.

But the problem is my 02 virtual machines are always stays on a Host2. Few weeks ago each VM was on on each host. How do I place each virtual machine on each host for the best performance.

How do I this?

2. I connect to the cluster using vSphere client 5.1, Under Host Summery I get the following message

"Configuration issues: Host is not in complaince with the attached profile"

I suspect this is the case for my question 1 ?

Many Thanks

1 - If you have only 2 VMs on your cluster of 2 nodes, disable DRS . And manually move a VM to a Host.

Or you can modify the recommandation for DRS to Agressive. Did you check that DRS is enable in fully automated mode?

2 - From which host did you create the host profile? Overwise, detach the host profile.

THank you for your reply.

Recommandation for DRS is 80% aggressive.  Yes DRS on fully Automated mode. You mean disable the fault tolarence for a VM and move the VM and enable fault tolarence again?

How do I find host profile is belong to which host? Sorry I am a new to cluster and also this was setup by the Datacenter for me.

Thanks

So, you dont have 2 Vms, you have one VM with fault tolerance?

if it is 2 VMs , you can create a anti-affinity rule for these VMs , it should be ok then.

1. Since the VM's are FT enabled DRS will not move VM's to single host nor vice verse since you have only 2 hosts.

Using FT with DRS check this doc http://pubs.vmware.com/vsphere-51/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-51-availab...

2. For host profile try checking host profile compliance as mentioned in KB VMware KB: Checking compliance of a host profile

Hi Thanks,

The default Host profile is applied. Each "Host Profile Compliance" status is "Noncompliance" with a red cross.

"Cluster Requirements Compliance" status is "Compliant"  with a green tick.

Host Compliant Failiur Message is

Failures agaist host Profile

The options VMFS3.HardwareAcceleratedLocking,DataMover.HardwareAcceleratedMove,DataMover.HardwareAcceleratedInit have been changed from their expected defuat values

Thanks

Hi,

I think  found the answer for the Host profile problem. I changed the following values to 1 for each host at > configurations > Under Software > Advanced Settings >

Under DataMover

HardwareAcceleratedInit

HardwareAcceleratedMove

Under VMFS3

HardwareAcceleratedLocking

Then the compliance status came back to green.

Thanks for the tips guys!

Thanks
