Removing "Update Failed" VMs from the VMM Administrator Console

Recently getting annoyed by the increasing number of VMs with status "Update
Failed". The last thing I remember that this happened after the one of my
Hyper-V host crashed, and ended up 2 identical VMs appear after the quick
migration took place.

Found this blog
http://blogs.technet.com/m2/archive/2010/04/16/removing-missing-vms-from-the-vmm-administrator-console.aspx
and below are my summary of the steps :

1. Close VMM Administrator Console
2. Stop "Virtual Machine Manager" service.
3. Backup the VMM database (optional)
4. Download and install "Microsoft SQL Server Management Studio Express"
from
http://www.microsoft.com/downloads/en/details.aspx?FamilyID=c243a5ae-4bd1-4e3d-94b8-5a0f62bf7796.
5. Launch "Microsoft SQL Server Management Studio Express", select VMM
database and execute script below.
6. Start the "Virtual Machine Manager" service.
7. The VMs with "Update Failed" should have gone by now.

The above method does not work for me all time. In case you have the same
issue after the steps above are performed, you may try to remove host
cluster from the VMM.


This is my last resource and it always works for me ☺
