VMware Cannot Add Host to Cluster

I am trying to set up HA but am having some difficulties.

I have created a cluster, Cluster1, but when I try to add a host I am unable.  If I try to add by the name of the host as shown in the DNS portion of ESXi vCenter says "cannot contact host".  The computer is named HP3 and I've tried that as well as hp3.mycompany.lan as shown in the DNS portion.  If I try adding by IP (10.0.1.99) it says that name already exists as that is what the host is called in vCenter.

What can I do to add my hosts to a cluster?

check you have DNS, Reverse DNS working, and setup correctly.

The DNS was not there.  It is now.  But now when I enter HP3 instead of getting cannot contact I get "the name 10.0.1.99 already exists"

Remove from what?  It is hosting production VMs.  Will they stay online?

just drag and drop the server into the cluster

you do not need to add the host again if already in vCenter

I've tried that.  Nothing happens.  After I try that the summary of the cluster says 0 hosts and 0 everything else.

Connected to vCenter = yes.
Hosts and Clusters selected = Yes.

if I click a host and drag do not release button, the mouse cursor changes to a block, then move this to your cluster, a wizard will appear about resource pools

Add Host option on the Cluster, should read Add New Host not in vCenter.

If I drag the host (10.0.2.99) and drag it around I get the "can't put this here" symbol" everywhere except over the cluster.  When I release the host over the cluster, nothing happens.  No confirmation of any kind.  Then the summary of the cluster indicates nothing is in there.

If I drag it to the Western cluster I do get an add host wizard, but not for the Fisher cluster.  Is it important which cluster it is in?

They are in different physical locations.

10.0.1.99 is more of a test host.  10.0.2.50 is production.  I thought I should keep those seperate.

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
you need to move to the correct cluster

Drafter421Author Commented:
Which to me should be Fisher Cluster but nothing is happening there when I try to drag the host into that.

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
if they are both managed by vCenter should be no issues

can the hosts see the same storage?
