Procedure
1 In the vSphere Client, browse to the vSphere HA cluster.
2 Click the Configure tab.
3 Select vSphere Availability and click Edit.
4 Click Failures and Responses and expand Response for Host Isolation.
5 To configure the host isolation response, select Disabled, Shut down and restart VMs, or Power off
and restart VMs.
6 Click OK.
Your setting for the host isolation response takes effect.
Configure VMCP Responses
Configure the response that VM Component Protection (VMCP) makes when a datastore encounters a
PDL or APD failure.
This page is editable only if you have enabled vSphere HA.
Procedure
1 In the vSphere Client, browse to the vSphere HA cluster.
2 Click the Configure tab.
3 Select vSphere Availability and click Edit.
4 Click Failures and Responses, and expand either Datastore with PDL or Datastore with APD .
5 If you clicked Datastore with PDL, you can set the VMCP failure response for this type of issue,
either Disabled, Issue Events, or Power off and restart VMs.
6 If you clicked Datastore with APD, you can set the VMCP failure response for this type of issue,
either Disabled, Issue Events, Power off and restart VMs--Conservative restart policy, or Power
off and restart VMs--Aggressive restart policy. You can also set Response recovery, which is the
number of minutes that VMCP waits before taking action.
7 Click OK.
Your settings for the VMCP failure response take effect.
Enable VM Monitoring
You can turn on VM and Application Monitoring and also set the monitoring sensitivity for your vSphere
HA cluster.
This page is editable only if you have enabled vSphere HA.
Procedure
1 In the vSphere Client, browse to the vSphere HA cluster.
