The failover message queue receives messages regarding failover activity.
Using the failover message queue allows an administrator to be notified before a failover occurs. This gives the administrator the ability to cancel the failover if the desired behavior is to prevent the failover at this time.
The failover message queue is defined when creating a cluster resource group using the Create Cluster (QcstCreateCluster) API. It can also be modified using the CL command and API for changing a cluster resource group. The failover message queue cannot be used with the iSeries™ Navigator cluster management interface.
Further details on the failover message queue can be found in the Cluster Resource Group API documentation. See the following descriptions for details on how to use the failover message queue.
