摘要： Enables any OS of plural OSs within any of plural logical-resource partitions (LPARs) of a CEC to use interpretive execution for synchronously-executable CHSC (channel subsystem call) commands. A CHSC command authorization mask (CCAM) is provided to control which CHSC commands are allowed to execute interpretively (with pass-through), and which commands are executed with hypervisor intervention (as all prior CHSC commands did). By enabling interpretive execution of those commands which can successfully operate with pass-through, significant system efficiency is obtained. And by disabling interpretive execution for a subset of CHSC commands (which are not allowed to execute with pass-through) potential system failures may be prevented. Thus, interpretive execution may be restricted differently among the OSs in a CEC. Novel CHSC command execution now handles multiple images of shared I/O resources by use of image identifiers, which could not be done before. The information requested by any OS issuing a CHSC command is filtered and optionally compacted by the I/O subsystem responding to the command by only providing information obtained from control blocks associated with the OS which issued the command. This is done by having a set of control blocks for each I/O resource, each control block in the set being associated with a particular OS.

摘要： Provides a method for increasing the connectivity of I/O resources to a multiplicity of operating systems (OSs) running in different resource partitions of a computer electronic complex (CEC) to obtain sharing of the I/O resources among the OSs of the CEC, including channels, subchannels (devices), and control units (CUs). The invention provides image identifiers (IIDs) for assigning resources to the different OSs. Each shared I/O resource has a sharing set of control blocks (CBs) in which a respective CB is assigned to (and located by) a respective IID of one of the OSs. Each of the CBs in a sharing set provides a different image of the same I/O resource. The different CB images are independently set to different states by I/O operations for the different OSs, so that the OSs can independently share the same I/O resource.

摘要： Provides a method for measuring the busy utilization time for I/O channel used by any of plural operating systems (OSs) in a CEC. The measured utilization time for any OS excludes the time shared channels are utilized by other OSs during a measurement period. A channel measurement facility (CMF) is provided in the I/O subsystem hardware and microcode for each of the OSs in the I/O subsystem. The CMF is logically constructed because it uses only a small portion of I/O resources already existing in a CEC by adding microcode to control these resources to perform the time measurement function. The resources for a logical CMF including the partial use of: an I/O processor to store identifiers of an assigned OS, the partial use of channel processors controlling channels selected by the assigned OS during a measurement period, the local storage of each I/O processor, and OS storage needed for communicating the measurement data from the CMF to the OS. Any CPU can control a measurement by issuing "set channel measurement" instructions for starting and stopping a measurement performed asynchronously by the CMF to release the CPU for other independent CPU operations during a measurement period. The instruction can also be used to test the status of any CMF.
摘要翻译：提供一种测量CEC中多个操作系统（OS）中任何一个使用的I / O通道的繁忙使用时间的方法。任何操作系统的测量使用时间不包括其他操作系统在测量期间利用的时间共享通道。在I / O子系统中的每个OS的I / O子系统硬件和微代码中提供了通道测量设备（CMF）。 CMF是逻辑构造的，因为它仅使用CEC中已经存在的I / O资源的一小部分，通过添加微代码来控制这些资源来执行时间测量功能。用于逻辑CMF的资源包括部分使用：I / O处理器来存储分配的OS的标识符，部分使用控制在测量期间由分配的OS选择的信道的信道处理器，每个I / O处理器和OS存储器，用于将测量数据从CMF传送到OS。任何CPU都可以通过发出“设置通道测量”指令来控制测量，用于启动和停止由CMF异步执行的测量，以在测量期间释放其他独立CPU操作的CPU。该指令也可用于测试任何CMF的状态。

摘要： A data processing I/O system including a main storage for storing data and data processing instructions arranged in software programs, and a channel subsystem having hardware for reporting conditions in the channel subsystem to the software. A special Channel Subsystem Call (CHSC) instruction is used to store event information from the channel subsystem into the main memory for use by the software such that new or restored resources such as a channel path, a channel path and partial control unit link address, or a channel path and full control unit link address, may be originally made accessible, or may be restored to the I/O system. A mechanism is also provided to inquire of a device how long it expects to not be accessible to give the device sufficient time to reset itself before it is varied offline, thus preventing a device from being isolated or "boxed" prematurely.

摘要： At least one standard size data block of a storage device is scanned for a logically bad pattern. If the logically pad pattern is detected, a block address that is associated with the standard size data block is added to a bad block table. If the logically pad pattern is not detected, it may be determined if the block address associated with the standard size data block is in the bad block table. If the logically pad pattern is not detected and if the block address associated with the standard size data block is in the bad block table, the block address may be removed from the bad block table. The logically bad pattern may have a first predefined data portion and a second predefined data portion and may be repeated the requisite number of instances to fill the standard size data block.
