1. A computer-implemented method for managing a cluster of compute nodes in a shared pool of configurable computing resources using a set of Small Computer System Interface Persistent Reservation (SCSI-PR) commands, the method comprising: monitoring, using the set of SCSI-PR commands, the cluster of compute nodes for an error event; detecting, based on a set of values derived from the set of SCSI-PR commands, the error event; determining, with respect to the error event, an error event response action; and initiating performance of the error event response action.
