Using Managed Object Browser to remove old vCOPS Registration

23rd December 2014 0 By Simon

Playing around in my home lab over the last couple of months I carried out an installation of vCenter Operations Manager (vCOPS), had a look around it and then promptly deleted the vApp after a month or so.

Spring forward a couple of months and going through the new vROPS 6 installation and going through the vCenter registration process with vROPS 6 I received the following error message.

Because this installation isn’t actually replacing an existing instance I decided against overriding the existing registration and decided to go with a de-registration, thereby allowing a fresh registration of vROPS 6.

Using the MOB incorrectly can lead to you breaking your vCenter server so please do so carefully.

Browse to your vCenter Server and add the /mob to the end of the address.

Click the value you want to inspect (in this instance it’s the com.vmware.vcops entry).

Highlight and copy the key value as we are going to use this to unregister the extension.

Paste the value in and click Invoke Method

Success is indicated by the void message

A refresh of the page shows the vCops extension has now been removed. You have successfully removed the vCOPS registration from vCenter.
