Safely remove VMHA

Hi all

I created a VMHA to play with, but now I want to remove it for the time being.

Below is a screen shot of what it looks like.

How do I safely remove HA and go back to "singular" esx hosts / VM's tree?

Just edit the cluster properties and Un-tick HA.

Then move the ESXi hosts out of the cluster, and delete the cluster.

Ok, what that is is just a Cluster. More than likely, it has HA enabled in the cluster. The name you gave the Cluster is "VMWARE HA", it looks like. So, What I would do is rt-click on the Cluster, go into Properties, then disable HA. Then, you can simply click on a host and drag it to the main Datacenter object ("...HQ"). The host and all its associated VMs will move. Then, do the same for the other host. Once all hosts are removed from the Cluster, if you wanna remove the Cluster, just rt-click on it and delete/remove it.

Apparently I have to enable Maintenance Mode first?

Shouldn't have to if you disable HA. What are you doing that is prompting for needing to place in Maint Mode?

Did you Un-tick the HA Option in the Cluster?

You could just remove the ESXi hosts esx1 and esx2, and just drag and drop them out of the cluster up into ...HQ.

VMHA is unticked on the VMware HA Cluster.

I then try to drag exs hosts into the container above "VMWare HA" and I get the message:

Enable Maintenance Mode then remove the host from the cluster. If the host is not responding, disconnect the host from the cluster and add it to the target location.

Okay, Enable Maintenance Mode, which will be okay, you'll just not be able to power-on any Machines, whilst in Maintenance Mode.

Actually, when putting the host in Maint Mode, you'll need to pwr down VMs if they're on or they will be vMotioned to the 2nd host.

So basically I need to arrange complete downtime to disable VMHA?

Unless you have DRS?

Why are you disabling HA?

coolsport00Commented:
Not necesarily. If your hosts have "like" CPUs, enable VMotion (need to create a VMotion-enabled VKernel port in vswitch on each host)

I enabled VMHA to play with, but in reality it is quite pointless at this stage becuase there is zero spare capacity on th ehosts  to hold more than what they already do :)

coolsport00Commented:
Yeah, if you dont have enough resources on remaining host/hosts, you're right, HA is pointless.

Okay, well, with it Disabled by Un-Ticking, it will not activate on the Cluster, so it's just the presentation of the VMs, that will look different.
