Disable mirroring on HA Pair

If a standby unit will be offline for a period of time, and connection or persistence mirroring is enabled, F5 recommends that you disable session mirroring and persistence mirroring until the standby unit is back online. To disable mirroring on the active unit once the standby unit is offline, perform the following procedure:

Version 11.0.0

Log in to the Traffic Management Shell (tmsh) by entering the following command: tmsh

Note: If you are currently logged in to the tmsh shell, you can skip this step.

To verify whether session mirroring is enabled, enter the following command: list /sys db statemirror.mirrorsessions

To disable session mirroring, you must modify the StateMirror.MirrorSessions db key by typing the following command: modify /sys db statemirror.mirrorsessions value disable

To disable persistence mirroring from an active persistence profile, use the following syntax: modify /ltm persistence mirror disabled

For example, to disable persistence mirroring from a hash persistence profile named MyHash, you would enter the following command: modify /ltm persistence hash MyHash mirror disabled

Repeat Step 3 for any other configuration objects that have persistence mirroring enabled. Save the change by typing the following command: save /sys config
