1. A computer-implemented method, comprising: during an ongoing copying of information from a first logical unit to a target logical unit, receiving an event notification for a pair of cluster nodes having a first cluster node and a second cluster node, the first cluster node controlling the copying of the information from the source logical unit to the target logical unit, wherein the event notification indicates an occurrence of a takeover event or a giveback event; upon receiving the event notification, suspending the copying of the information from the source logical unit to the target logical unit; transferring one or more processes from the first cluster node to the second cluster node, the one or more processes related to the copying of the information from the source logical unit to the target logical unit; and resuming the copying of the information from the source logical unit to the target logical unit.
