ESX: Unable to add host - Timed waiting for vpxa to start

Hi All,

I recently rebuild an ESX server. Same IP, Hostname, but new disks and additional RAM.

I can access the stand alone server without any issue and everything seems fine, however when I try to add it to vCenter I get the follow error.

ESX error
Any ideas?

Is the version of vCenter the correct version to manage this host ?

e.g. ESXI 5.1 and vCenter Server 5.1

have you Restarted Network Management Agents ?

Also when you add the host, was it already added ? (eg in the list!).

Remove from Inventory and start again- Add.

That's the issue!

vCenter 5.1 CANNOT Manage ESXi 5.5!

vCenter Server *MUST* be the same version or higher.

Upgrade vCenter Server to 5.5, or downgrade ESXi to 5.1.

To upgrade vCenter do I just download the ISO and run it over the top?

If so, will it retain the Update Manager tab?

You will need to upgrade all the components of vCenter 5.1.

Thanks, got it working via an upgrade.

Minor issue of having to log into the vCenter web console to reassign our AD domain admins group back using the Administrator@vsphere.local account.
