Enable high availability

Last published : Oct 01, 2026

If high availability was previously configured and then disabled, the restart priorities defined for each VM in the pool are saved and retained.

You can re-enable high availability to reuse these same settings in one of the following ways:

Select the pool in the Resources pane, select the HA tab, and then select Enable HA.
In the Pool menu, select High Availability > Enable HA.
Right-click on the pool in the Resources pane and choose High Availability > Enable HA from the context menu.
