Note: This option is only relevant in a High Availability (HA) setup.
This option is used to select a preferred HA unit. This option can be set to either Prefer First HA, Prefer Second HA or No Preferred Host (default).
When set to Prefer First HA, if the LoadMaster fails over, the master will revert back to HA1 when HA1 comes back online.
When set to Prefer Second HA, if the LoadMaster fails over, the master will revert back to HA2 when HA2 comes back online.
When No Preferred Host is selected, if there is a failover on the LoadMaster, the unit that becomes master will remain as master (no failback will happen).
To change this option in the LoadMaster Web User Interface (WUI):
In the main menu, select Local Administration > HA Parameters.
- Select the relevant option in the Switch to Preferred Server drop-down list.
