Ramblings from another nerd on the grid
VM Recovery Tool The stand-alone Virtual Machine Recovery Tool works with System Center 2012 – Virtual Machine Manager (VMM) to temporarily remove a host, cluster, virtual machine, or service from VMM when that object is in a failed or persistent warning state due to environmental conditions, third-party applications, or other causes. After resetting the state of the object, once VMM refreshes, the object will appear as healthy in VMM. This tool does not repair a damaged or incorrectly created virtual machine or corrupt .vhd file. It deals with state information stored in the VMM database. For additional details about the tool, see Using the Virtual Machine Recovery Tool for System Center 2012 - Virtual Machine Manager (VMM).
Important This program is not a supported part of the VMM product. This program is offered “as-is”.
Virtual Machine Manager Configuration Analyzer (VMMCA) The VMMCA is your first line of defense in troubleshooting an issue in the System Center 2012 – Virtual Machine Manager environment. VMMCA is a diagnostic tool you can use to evaluate important configuration settings for computers that are either running VMM server roles or are acting as virtual machine hosts. The VMMCA scans the hardware and software configurations of the computers you specify, evaluates them against a set of predefined rules, and then provides you with error messages and warnings for any configurations that are not optimal.
Be sure to read the disclaimers and other notes in the download area. Some of the programs are not a supported part of the VMM product. They are offered “as-is”.
