Suspending an appliance from an HA group by using the IBM MQ Console

You can temporarily remove an appliance from a high availability group by using the IBM® MQ Console.

About this task

When you remove an appliance from an HA group, all queue managers that run on the suspended appliance are failed over to the other appliance. You should not suspend both appliances in the HA group at the same time.

Note: You should check the HA status of the appliance before you suspend it from the HA group by using the status command, see status.
  • If the status is Synchronization in progress you should let the synchronization finish. If you suspend an appliance in an HA group while a queue manager is synchronizing, the queue manager ends immediately, rather than finishing the synchronization.
  • If the status is Partitioned then resolve the state before suspending the appliance, see Resolving a partitioned problem in a high availability configuration.

Procedure

  1. In the Manage view, open the High availability tab.
  2. In the tile for the appliance that you want to suspend, select Suspend appliance from the menu Shows the menu icon. The appliance is suspended from the HA group.
