The Failure conditions and VM response page allows you to choose settings that determine how vSphere HA responds to host failures and isolations. These settings include the VM restart priority, host isolation response, settings for VM Component Protection, and VM monitoring sensitivity.

About this task

Virtual Machine Response page is editable only if you enabled vSphere HA.

Procedure

  1. In the vSphere Web Client, browse to the vSphere HA cluster.
  2. Click the Manage tab and click Settings.
  3. Under Settings, select vSphere HA and click Edit.
  4. Expand Failure Conditions and VM Response to display the configuration options.

    Option

    Description

    VM restart priority

    The restart priority determines the order in which virtual machines are restarted when the host fails. Higher priority virtual machines are started first. This priority applies only on a per-host basis. If multiple hosts fail, all virtual machines are migrated from the first host in order of priority, then all virtual machines from the second host in order of priority, and so on.

    Response for Host Isolation

    The host isolation response determines what happens when a host in a vSphere HA cluster loses its console network connection, but continues running.

    Response for Datastore with Permanent Device Loss (PDL)

    This setting determines what VMCP does in the case of a PDL failure. You can choose to have it Issue Events or Power off and restart VMs.

    Response for Datastore with All Paths Down (APD)

    This setting determines what VMCP does in the case of an APD failure. You can choose to have it Issue Events or Power off and restart VMs conservatively or aggressively.

    Delay for VM failover for APD

    This setting is the number of minutes that VMCP waits before taking action.

    Response for APD recovery after APD timeout

    You can choose whether or not VMCP resets a VM in this situation.

    VM monitoring sensitivity

    Set this by by moving the slider between Low and High. You can also select Custom to provide custom settings.

  5. Click OK.
