Configuring command propagation

September 21, 2020

Contributed by:

In an HA setup, any command issued on the primary node propagates automatically to, and is executed on, the secondary before it is executed on the primary. If command propagation fails, or if command execution fails on the secondary, the primary node executes the command and logs an error. Command propagation uses port 3010.

In an HA pair configuration, command propagation is enabled by default on both the primary and secondary nodes. You can enable or disable command propagation on either node in an HA pair. If you disable command propagation on the primary node, commands are not propagated to the secondary node. If you disable command propagation on the secondary node, commands propagated from the primary are not executed on the secondary node.

Note

After reenabling propagation, remember to force synchronization.

If synchronization occurs while you are disabling propagation, any configuration-related changes that you make before the disabling of propagation takes effect are synchronized with the secondary node. This is also true for cases where propagation is disabled while synchronization is in progress.

To disable or enable command propagation by using the command line interface

At the command prompt, type:

set HA node -haProp DISABLED
set HA node -haProp ENABLED

To disable or enable command propagation by using the GUI

Navigate toSystem>High Availabilityand, on theNodestab, open the node.
Clear or select the Primary node will propagate configuration to the Secondary option.
