This article relates to LoadMaster firmware version 7.2.53.
In LoadMaster firmware version 7.2.53, a new High Availability (HA) option was introduced that allows you to specify that a LoadMaster configured in HA reboots if any configured interface loses connectivity with the network (that is, experiences a link failure). The reboot occurs regardless of the LoadMaster's HA status (Primary or Standby).
This new option is called Hard Reboot on link Failure. When this check box is enabled, the LoadMaster is forced to reboot if there is a link failure (if an interface goes down). If either LoadMaster goes down (whether it is in active or standby mode) it will reboot. The Hard Reboot on link Failure check box is available in the System Configuration > HA Parameters screen when both of these are true:
High Availability (HA) is configured
The Switch to Preferred Server option is set to No Preferred Server.
You cannot have a preferred server if Hard Reboot on link Failure is enabled - if you did, it could lead to circular swapping between the active and standby LoadMaster units.
