Use preferred nodes

 

It can be useful when using Active/Active mode to configure a preferred node for each queue manager. However, in general it is better not to set a preferred node but to rely on a manual failback. Unlike some other relatively stateless resources, a queue manager can take a while to fail over (or back) from one node to the other. To avoid unnecessary outages, test the recovered node before failing a queue manager back to it. This precludes use of the immediate failback setting. We can configure failback to occur between certain times of day.

Probably the safest route is to move the queue manager back manually to the desired node, when you are certain that the node is fully recovered. This precludes use of the preferred node option.
