Option types for HA pairs

Some options must be the same on both nodes in the HA pair , while some can be different, and some are affected by failover events.

In an HA pair , options are one of the following types:

  • Options that must be the same on both nodes for the HA pair to function correctly
  • Options that might be overwritten on the node that is failing over

    These options must be the same on both nodes to avoid losing system state after a failover.

  • Options that should be the same on both nodes so that system behavior does not change during failover
  • Options that can be different on each node
Note: You can find out whether an option must be the same on both nodes of an HA pair from the comments that accompany the option value when you enter the option command. If there are no comments, the option can be different on each node.
