Hyper-V Manager and Failover Cluster Tools

I’ve noticed from the query hits against the master install document that it isn’t obvious how to access these tools.

Installation

You need a copy of Windows 7 (Professional or higher) or a GUI installation of Windows Server 2008 R2.

Windows 7

  1. Download and run the installation pack for Remote Server Administration Tools.
  2. Open the Control Panel.
    • Category view: Programs->Turn Windows features on or off (top of the right pane)
    • Small/Large Icons view: Programs and Features->Turn Windows features on or off (left pane)
  3. Expand “Remote Server Administration Tools”.
  4. These tools extend far beyond just managing Hyper-V and a cluster. The items relevant to this posting are:
    • Feature Administration Tools->Failover Clustering Tools
    • Hyper-V Tools

Windows Server 2008 R2

  1. Open Server Manager (right-click “Computer” and click “Manage”).
  2. Highlight the “Features” node in the left pane.
  3. Click “Add Features” either in the right pane or on the context menu for the Features node.
  4. The features relevant to this posting are in the same path as #4 from the Windows 7 directions above. Note that since this is a server, it has a check box in the root tree to install Failover Clustering. Doing so at that level enables the server to become a candidate for clustering, which, if it’s a management server, is probably not what you want.

Usage

For both Windows 7 and Server 2008 R2, the tools are located under Start->Administrative Tools.

Hyper-V Manager

  • This tool is not cluster aware.
    • You must manage the hosts individually using the “Connect to Server…” links for every host.
    • It cannot migrate VMs.
  • Once a server is added, the tool remembers it each time you run the program and will attempt to reconnect.
  • Use this tool if you want to create non-clustered VMs on a clustered Hyper-V host, which SCVMM cannot do (this shortcoming is supposed to be addressed in SCVMM 2012).
  • Use this tool to manage your virtual networks/switches. SCVMM also cannot do this (another shortcoming that 2012 is intended to cover).
  • Because it is not cluster-aware, all VMs created in Hyper-V Manager are non-HA. If you have a VM in High Availability mode that you wish to convert to non-HA, use this tool to export and import the VM.

Failover Cluster Manager

  • Use this tool to build and manage your clusters. It is aware of the Hyper-V role but will call Hyper-V Manager for any VM maintenance tasks. SCVMM 2012 is expected to take over much of what this tool is used for in relation to Hyper-V.
  • Use this tool to build and manage Cluster Shared Volumes (CSV).
  • This tool can Quick and Live Migrate VMs.
  • This tool can convert a non-HA VM to high availability mode. It will not convert the other way.
  • This tool manages the cluster networks (Cluster Communications, CSV, LiveMigration, and Management). It will not manage your virtual switches.
  • Use this tool if you need to evict a node from your cluster (this should be a tool of last resort; eviction tends to cause more problems than it solves).
