RemoveMissingVMs

Occasionally, after a cluster failover, duplicate virtual machines may appear in the System Center Virtual Machine Manager (VMM) Administrator Console: one with a status of Missing, the other with a different status. The missing virtual machines can be difficult to remove. The script in this topic is a SQL Server script that removes the missing virtual machines for you.

注意

The script removes all virtual machines with the status of Missing from the VMM database. The script does not delete any virtual machines from any host computer, whether it is a Hyper-V, Virtual Server, or VMware-based host.

The following steps help you prepare your system and run the script:

  1. Close the VMM Administrator Console.

  2. Stop the Windows service named VMMService on the VMM server.

  3. Make a full backup of the VMM database.

  4. Install Microsoft SQL Server Management Studio Express on the same computer on which the VMM database is stored.

    ヒント

    Microsoft SQL Server Management Studio Express is a free download from Microsoft that you can find on the Microsoft Download Center (https://go.microsoft.com/fwlink/?LinkId=190524).

  5. Open SQL Server Management Studio Express, select the VMM database, and then run the following SQL Server script. This should delete all missing virtual machines with a status of Missing from the VMM database. If the script was successful, you will see the following output: Commands(s) completed successfully.

  6. After the SQL Server script has completed, restart the VMMService and open the VMM Administrator Console to verify that the missing virtual machines are now deleted.
