High Availability
What does the option Switch to Preferred Server do?
This option is used to select a preferred HA unit. This option can be set to either HA1, HA2 or No preferred host (default).
- When set to HA1, if the LM fails over, the Master will revert back to HA1 when HA1 comes back online
- When set to HA2, if the LM 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 LM, the unit that becomes Master will remain as Master (no failback will happen)
To change this option in the WUI
- Select the System configuration > Miscellaneous Options > Ha Parameters option
- Select the preferred option in the Switch to Preferred Server dropdown list
