摘要： In a partitioned process environment, storage is reassigned by a shuffle of guest absolute address spaces which may be reassigned among partitions without restriction as to the position of the space to be reassigned relative to the position of the partition to which it is to be assigned. The reassignment is accomplished by adjusting the origin addresses by an adjustment value corresponding to the size of the address space of an additional memory area to be added to a selected partition. Furthermore, the size of the address space of the selected partition is increased by the same adjustment value. The system employs duplicated origin and limit arrays which are used to convert from a partition (guest) absolute address to a system (host) absolute address and uses duplicated configuration arrays by which the system absolute addresses are converted to physical memory addresses. Revised origin and limit information and configuration information is stored in an origin and limit array in the stand by state and in a configuration array in the stand by state. Autonomously operating circuitry is responsive to control signals to temporarily suspend memory commands from the input-output system, to reconfigure the origin and limit arrays and the configuration arrays to enable the system to use the revised information and, thereafter, to resume the processing of memory commands from the input-output system.

摘要： A data processing system has a processing unit and a memory which provides a common pool of physical storage. This storage is initially assigned as either main storage or expanded storage during power on. Subsequent to the initial assignment, storage assigned as main storage or expanded storage may be unassigned and thus returned to the common pool. Once returned to the common pool, the storage may be reassigned as either main storage or expanded storage. The storage reassignment is done dynamically without requiring a reset action and transparent to the operating system and any active application programs.

摘要： Automatic machine methods and apparatus for determining which components of an I/O configuration are shared by other components of the configuration. The information can be obtained through the use of existing self-description facilities and unique identifiers. By noting which channel paths are used to obtain configuration-data records and examining the unique identifiers provided for each I/O items it can be determined which I/O devices are accessible through the same control unit, and which control units provide access to the same I/O device. Furthermore, by examining the unique identifiers provided, it can be determined which I/O subsystems and which control units or channel subsystems are accessible through the same dynamic switch and which dynamic switches provide access to the same I/O subsystem of channel subsystem. A programmable subchannel is provided to enable communication between a CEC and an electrically-connected I/O item not represented in the current I/O configuration description being used by the CEC. Without the programmed subchannel, the CEC cannot access any I/O item not represented in the CEC's current I/O configuration description.

摘要： A method and system to eliminate service hardware previously provided with an adapter by providing a novel way to transfer its hardware service functions to a remote service hardware found elsewhere in a computer system, such as a mainframe. The transferred service controls include enabling the remote service hardware to control the updating of the adapter microcode; remotely control a recovery process for the adapter by remotely initializing its microcode, and remotely logging out and recovering from error conditions detected in the adapter; and remotely forcing a logout and recovery when the host OS detects a failure in the adapter. A standard I/O channel interface (optical or electronic) is provided between the adapter and an IOSS (Input Output Subsystem) of a computer system which has its own service processor element (SPE) used for servicing the computer system per se. The invention provides virtual service hardware for the adapter, but uses the SPE for its service hardware. The SPE is remote from the adapter in the sense that the SPE and the adapter can only communicate with each other over the standard I/O channel interface. The servicing functions required by the adapter are transferred to, and handled by, the SPE by internal I/O facilities (iIOF) provided in the IOSS, which change the internal subchannel architecture of the IOSS.
