Abstract
A mechanism is provided in a storage control unit in a data processing system for providing unsolicited global disconnect requests to users. The mechanism stores lock control data in the storage control unit. The storage control unit allocates its resources into a plurality of clusters. Responsive to a given user connecting to a given partition that is for a logical subsystem resident on a first cluster within the plurality of clusters, the mechanism sends reflected partition information from the first cluster to a second cluster within the plurality of clusters. Responsive to the first cluster experiencing a failure condition, the mechanism moves control data from one or more logical subsystems from the first cluster to the second cluster and for each logical subsystem that moved from the first logical subsystem to the second logical subsystem and that has reflected partition information, presents unsolicited status to one or more users.
