Abstract
Provided are a method, system, and article of manufacture to manage storage resources in a storage system. Requests by processing systems are received for access to a control block providing information on an address assigned to one of the storage resources to access. A token is generated for each processing system requesting the control block uniquely identifying the processing system and the control block. The processing systems are provided copies of the requested control blocks to use to access the storage resource. A request is received to modify one of the control blocks for one of the storage resources. A determination is made as to whether at least one of the tokens was generated for the control block to modify. At least one processing system associated with the determined at least one token is provided a copy of the modified control block to use to access the storage resource associated with the control block.
