Force Lock a Host Using HorizonΒΆ

Force locking an unlocked host takes it out of service immediately for configuration and maintenance purposes.


A force lock operation on a worker host causes an immediate service outage on all containers and causes the host to reboot.


  1. Try to lock the host normally using Lock Host.

    For more information, see Lock a Host Using Horizon.

  2. If the Lock Host attempt fails for a worker host, manually relocate containers running on the host, and then try using Lock Host again.

  3. Use a force lock only if the above steps fail to lock the host.

    1. From Admin > Platform > Host Inventory, select the Hosts tab.

    2. From the Edit menu for the host, select Force Lock Host.


      The system displays a warning message appropriate to the personality of the host.
