Disabling VMware High Availability (HA) (1008025)

Details

This article provides steps to disable VMware HA.
 
You may want to disable the VMware High Availability (HA) feature, for example, while downgrading a license. VMware HA might not be supported by the downgraded license.

Solution

Note: You may need to complete this process for multiple clusters. VMware HA can be disabled only if there are no virtual machines with VMware Fault Tolerance (FT) enabled. If there are virtual machines with VMware FT enabled in the cluster you are disabling, turn off VMware FT before disabling VMware HA. The process of turning off VMware FT is described in Disabling or Turning Off VMware FT (1008026) .

Note: Virtual Machine Monitoring will also be disabled when HA is disabled.

  3. Locate the cluster.
  4. Right-click the cluster and click Edit Settings.

Note: The process may take some time to complete.
