Patent ID: 8365008

Claim:
A method, in a storage control unit in a data processing system, for providing unsolicited global disconnect requests to users, the method comprising: storing lock control data in the storage control unit, wherein the storage control unit allocates its resources into a plurality of clusters and wherein the lock control data contains knowledge about locks, logical subsystems, partitions, and users of the partitions; 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, sending reflected partition information from the first cluster to a second cluster within the plurality of clusters, wherein the reflected partition information identifies one or more logical subsystems, partitions, and connected users; and responsive to the first cluster experiencing a failure condition, moving control data from one or more logical subsystems from the first cluster to the second cluster, storing the control data for the one or more logical subsystems in association with 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, presenting unsolicited status to one or more users, wherein the unsolicited status comprises a global disconnect requested message and wherein at least one user within the one or more users reads the unsolicited status.
