摘要： An aspect includes determining, via a processor, context attributes of a storage. Data address translation (DAT) tables are created, via the processor, to map virtual addresses to real addresses within the storage. When detecting, via the processor, that a context attribute of the storage has changed, and the DAT tables are updated based at least in part on the changed context attributes of the storage.

摘要： A computer-implemented method, according to one approach, includes: receiving a first request to perform a write operation from a host, and performing the write operation. Metadata corresponding to the first request is sent to the secondary data storage device, and metadata corresponding to a second request to perform the write operation is received from the secondary data storage device, where the second request was received at the secondary data storage device from the host. The metadata corresponding to the first and second requests is used to determine whether the write operation has been mirrored across the primary and secondary data storage devices. In response to determining that the write operation has been mirrored across the primary and secondary data storage devices, a response is sent to the secondary data storage device which indicates that the write operation has been reconciled across the primary and secondary data storage devices.

摘要： A methodology for creating and using information identifying what and how software and/or firmware modules are used in computer systems, called functional exploitation data. The functional exploitation data can be used to identify what modules should be updated and how updates should be implemented. The functional exploitation data can also be used to identify other computer systems as candidates for updates based on similarity to computer systems that have reported problems, and propose implementing similar updates on the candidates. Functional exploitation data can also be used to identify under-utilized modules for enhancements or greater advocacy. The functional exploitation data can be implemented in the form of a concatenated string.

摘要： Provided are a computer program product, system, and method for sharing alias addresses among logical devices for a control unit managing access by hosts to logical devices configured with capacity from attached physical devices. An alias management group of logical devices and alias addresses assigned to the logical devices is configured. A plurality of requests to establish an association of the host with a logical device and the alias addresses assigned to the logical devices in the alias management group are received from a host. Acknowledgment is made to the host that the association is established in response to determining that the host is assigned the logical devices and alias addresses of the logical devices in the alias management group. The host can use one available alias address assigned to any one of the logical devices to access any one of the logical devices indicated in the association.

摘要： A method, system, and computer program product are described for a machine selecting a selected adapter among two or more adapters that perform a same function. The method includes generating a request, at the machine, for the function, and calculating a time indicator associated with each of the two or more adapters based on a respective adapter queue time factor (QTF) associated with each of the two or more adapters, the adapter QTF associated with each of the two or more adapters being a computed value. The method also includes selecting the selected adapter and submitting one or more requests to the selected adapter of the two or more adapters to perform the function based on a comparison of the time indicator associated with each of the two or more adapters.

摘要： Aspects include a computer-implemented method for managing alias devices across logical control units. Aspects include establishing one or more alias management groups associated with a set of one or more logical control units. Aspects also include responsive to one or more changes to the set of network paths of a first logical control unit in the set of logical control units performing a method comprising: marking a first alias management group associated with the first logical control unit as invalid for alias borrowing. Then, performing a first synchronized CPU enablement operation that ensures each of the plurality of CPUs has enabled. Aspects include determining whether a second alias management group exists having a second set of control units that matches the set of paths of the first control unit and associating the first control unit with the second alias management group.

摘要： A system for accelerating database transaction processing by controlling data replication includes a first control unit configured to manage a first storage device and at least one second control unit configured to manage a second storage device. The first control unit writes first data to the first storage device and sends the first data to the second control unit responsive to receiving from a host a first write command including the first data. The first control unit writes second data to the first storage device without sending the second data to the second control unit responsive to receiving from the host a second write command. The second control unit writes the first data to the second storage device responsive to receiving the first data. The second control unit writes the second data to the second storage device responsive to receiving from the host a third write command.
