Abstract: One or more techniques and/or computing devices are provided for communicating storage controller failures utilizing service processor traps. A first storage controller, of a first storage cluster, has a disaster recovery relationship with a second storage controller of a second storage cluster. The first storage controller comprise a first service processor configured to monitor health of the first storage controller. Responsive to identifying a failure of the first storage controller, the first service processor uses stored communication configuration of a second service processor of the second storage controller to send a service processor trap to the second service processor. In this way, the second service processor initiates a switchover operation by the second storage controller to provide clients with failover access to data previously available through the first storage controller before the failure. Proactive notification of storage controller failures utilizing service processor traps reduces client data access disruptions.
