6 In the Available heartbeat datastores pane, select the datastores that you want to use for
heartbeating.
The listed datastores are shared by more than one host in the vSphere HA cluster. When a datastore
is selected, the lower pane displays all the hosts in the vSphere HA cluster that can access it.
7 Click OK.
Set Advanced Options
To customize vSphere HA behavior, set advanced vSphere HA options.
Prerequisites
Verify that you have cluster administrator privileges.
Note Because these options affect the functioning of vSphere HA, change them with caution.
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 Advanced Options.
5 Click Add and type the name of the advanced option in the text box.
You can set the value of the option in the text box in the Value column.
6 Repeat step 5 for each new option that you want to add and click OK.
The cluster uses the options that you added or modified.
What to do next
Once you have set an advanced vSphere HA option, it persists until you do one the following:
n
Using the vSphere Client, reset its value to the default value.
n
Manually edit or delete the option from the fdm.cfg file on all hosts in the cluster.
