SLIDE 31 ha_vm_restart_additional_delay - (Optional) Additional delay in seconds after ready condition is met. A VM is
considered ready at this point. Default: 0 (no delay).
ha_vm_restart_timeout - (Optional) The maximum time, in seconds, that vSphere HA will wait for virtual machines
in one priority to be ready before proceeding with the next priority. Default: 600 (10 minutes).
ha_host_isolation_response - (Optional) The action to take on virtual machines when a host has detected that it
has been isolated from the rest of the cluster. Can be one of none , powerOff , or shutdown . Default: none .
ha_advanced_options - (Optional) A key/value map that species advanced options for vSphere HA.
HA Virtual Machine Component Protection settings
The following settings control Virtual Machine Component Protection (VMCP) in vSphere HA. VMCP gives vSphere HA the ability to monitor a host for datastore accessibility failures, and automate recovery for aected virtual machines. Note on terminology: In VMCP, Permanent Device Loss (PDL), or a failure where access to a specic disk device is not recoverable, is dierentiated from an All Paths Down (APD) failure, which is used to denote a transient failure where disk device access may eventually return. Take note of this when tuning these options.
ha_vm_component_protection - (Optional) Controls vSphere VM component protection for virtual machines in this
- cluster. Can be one of enabled or disabled . Default: enabled .
ha_datastore_pdl_response - (Optional) Controls the action to take on virtual machines when the cluster has
detected a permanent device loss to a relevant datastore. Can be one of disabled , warning , or
restartAggressive . Default: disabled . ha_datastore_apd_response - (Optional) Controls the action to take on virtual machines when the cluster has
detected loss to all paths to a relevant datastore. Can be one of disabled , warning , restartConservative , or
restartAggressive . Default: disabled . ha_datastore_apd_recovery_action - (Optional) Controls the action to take on virtual machines if an APD status on
an aected datastore clears in the middle of an APD event. Can be one of none or reset . Default: none .
ha_datastore_apd_response_delay - (Optional) Controls the delay in minutes to wait after an APD timeout event to
execute the response action dened in ha_datastore_apd_response . Default: 3 minutes.
HA virtual machine and application monitoring settings
The following settings illustrate the options that can be set to work with virtual machine and application monitoring on vSphere HA.
ha_vm_monitoring - (Optional) The type of virtual machine monitoring to use when HA is enabled in the cluster. Can
be one of vmMonitoringDisabled , vmMonitoringOnly , or vmAndAppMonitoring . Default:
vmMonitoringDisabled . ha_vm_failure_interval - (Optional) If a heartbeat from a virtual machine is not received within this congured
interval, the virtual machine is marked as failed. The value is in seconds. Default: 30 .
ha_vm_minimum_uptime - (Optional) The time, in seconds, that HA waits after powering on a virtual machine before
monitoring for heartbeats. Default: 120 (2 minutes).
