    Data Center Operation PRO Pack PRO tip implementation rules

    List of recovery rules applied for virtual machine hosts in or outside clusters.

    Hyper-V hosts in a cluster
    • If there are hosts in a cluster, impacted hosts are put in maintenance mode.
    • Virtual machines on those hosts are migrated within the cluster.

    Hyper-V hosts outside a cluster
    • If there are hosts outside a cluster, the recovery script finds potential hosts and virtual machines are migrated from the impacted host.
    • The status of the impacted host is changed from available to unavailable.

    Stand-alone Hyper-V host in a cluster
    • If there is one host in a cluster, the virtual machines on the host will be put in saved state and the host is still put in maintenance mode.
    • Virtual machines on that host are not migrated from that host.

    Stand-alone Hyper-V host outside cluster
    • If there is a stand-alone host outside a cluster, an error message is displayed in the PRO tip.
      • PRO cannot migrate virtual machine (virtual machine name) because no other hosts are available in the host group or host cluster.
      • PRO cannot migrate a virtual machine.
    • The status of the impacted host is changed from available to unavailable.

    Multiple Hyper-V hosts in maintenance mode
    • If multiple hosts are being impacted at the same time, a PRO tip is created for each impacted host. The PRO tips will be automatically implemented if automatic implementation of PRO tips has been configured. Otherwise, you should manually implement the PRO tips.

    Virtual machine is excluded from PRO host-level action
    • If there are Hyper-V hosts in a cluster that have been set to be excluded from PRO host-level action, the hosts are put in maintenance mode. This means that Virtual Machine Manager will still migrate these virtual machines.
    • If there are Hyper-V hosts outside a cluster that have been set to be excluded from PRO host-level action, Virtual Machine Manager will not migrate these virtual machines.

    Note

    If you are integrating with Virtual Machine Manager 2012, your setup may look a little different from the instructions and images in this user assistance since these have been created for integration with Virtual Machine Manager 2008 R2.
