Configuring Responses to Failures
The Failure and Responses pane of the vSphere HA seings allows you to congure how your cluster
should function when problems are encountered.
In this part of the vSphere Web Client, you can determine the specic responses the vSphere HA cluster has
for host failures and isolation. You can also congure VM Component Protection (VMCP) actions when
Permanent Device Loss (PDL) and All Paths Down (APD) situations occur and you can enable VM
monitoring.
The following tasks are available:
1 Respond to Host Failure on page 30
You can set specic responses to host failures that occur in your vSphere HA cluster.
2 Respond to Host Isolation on page 31
You can set specic responses to host isolation that occurs in your vSphere HA cluster.
3 Congure VMCP Responses on page 31
Congure the response that VM Component Protection (VMCP) makes when a datastore encounters a
PDL or APD failure.
4 Enable VM Monitoring on page 31
You can turn on VM and Application Monitoring and also set the monitoring sensitivity for your
vSphere HA cluster.
Respond to Host Failure
You can set specic responses to host failures that occur in your vSphere HA cluster.
This page is editable only if you have enabled vSphere HA.
Procedure
1 In the vSphere Web Client, browse to the vSphere HA cluster.
2 Click the tab.
3 Select vSphere Availability and click Edit.
4 Click Failures and Responses and then expand Host Failure Response.
5 Select from the following conguration options.
Option Description
Failure Response
If you select Disabled, this seing turns o host monitoring and VMs are
not restarted when host failures occur. If Restart VMs is selected, VMs are
failed over based on their restart priority when a host fails.
Default 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
rst. If multiple hosts fail, all virtual machines are migrated from the rst
host in order of priority, then all virtual machines from the second host in
order of priority, and so on.
VM Dependency Restart Condition
A specic condition must be selected as well as a delay after that condition
has been met, before vSphere HA is allowed to continue to the next VM
restart priority.
6 Click OK.
Your seings for the host failure response take eect.
