sol14515: The Force to Standby feature should not be used when the HA group feature is enabled

Original Publication Date: 08/08/2013
Updated Date: 06/04/2014


The high availability (HA) groups feature is designed to assign the active system without user intervention. Therefore, the operator of a BIG-IP system should not attempt to manually control HA operation by using the Force to Standby feature. As a result, the HA group feature may override the active/standby state and may reassign the active system automatically.

If a manual change of the active state is required, F5 recommends that you disable the HA group feature, or that you take the active system offline temporarily.


To take a system offline, perform one of the following procedures:

Using the Configuration utility to take a system offline

  1. Log in to the BIG-IP Configuration utility of the system you want to take offline.
  2. Navigate to Device Management > Devices.
  3. Select the system for which you are logged in.
  4. Click Force Offline.
  5. Click OK.

Using the Traffic Management Shell (tmsh) to take a system offline

  1. Log in to the Traffic Management Shell (tmsh) by typing the following command:


  2. To take a system offline, type the following command:

    run sys failover offline

  3. To bring a system online, type the following command:

    run sys failover online
