VMM Tricks: Removing missing VMs from the VMM Administrator Console

Source

it has come to our attention that there are some customer complaints with regards to missing virtual machines in the administrator console after a cluster failover. Since it is not easy to remove those VMs from the VMM administrator console, Gokcen from our team wrote a script that will allow you to clean those VMs up. Here are the steps to follow.

  1. First close the VMM Administrator Console
  2. Then, stop the VMMService windows service on the VMM server computer
  3. Take a FULL database backup of the VMM database [Just in case; this is a safety net in case something goes wrong]
  4. Now you are ready to clean up any missing VMs. it is important to notice that all missing Virtual Machines in this VMM environment will be deleted from the VMM database. we are not deleting any virtual machines from any virtualization host computer. basically we are not touching anything on Hyper-V, Virtual Server, or VMware ESX computers
  5. Install Microsoft SQL Server Management Studio Express on the same computer where the VMM database exists. This is a free download from microsoft and you can search for it on Bing.
  6. Open SQL Management Studio, select the VMM database and run the SQL script below. That should delete all VMs that are in the missing state in the VMM database.
  7. Once the sql script is completed, restart the VMMService and open the Administrator Console. All your missing VMs should now be “eliminated” 🙂

    Has anyone tried this script to confirm it works safely?

    im having this issue but somewhat hesitant to proceed until i know this has been well tested.

    thanks,
