Disable mirroring on HA Pair

F5 documentation mentions that you need to disable mirroring when upgrading the software on an HA Pair. How do I do that and how do I re-enable it? Why does this need to be done? Thanks.

By default, mirroring is not enabled.

 

mirroring is configured in virtual server configuration (Advanced view --> Connection Mirroring). In most of deployments, mirroring must not been activated because :

 

  • HTTP connection are very short
  • mirroring is not supported when SSL profile (client or server) is configured

In version before 11.0, mirroring can be configured without error Since version 11.0, mirroring cannot be configured generating an error

 

If you upgrade a 10.x to 11.x, the upgrade will not warn you until you reboot and the configuration will not be loaded if one unsupported configuration is still enabled.
