摘要： An I/O request time limit value is set in a request-based, device-based, data-set-based, or workload-based time limit field, for transactions performing I/O operations to I/O devices in a data processing system. A scan routine compares the total time for the I/O request (including waiting time and retry time) against the appropriate time limit(s), and terminates the I/O request if the time limit is exceeded. If an active I/O request is interrupted as a result of an I/O error, retry is prohibited if the total I/O request time (including retry time) exceeds the appropriate time limit, or is within a threshold value of the appropriate time limit.
摘要翻译：对于在数据处理中对I / O设备执行I / O操作的事务，在基于请求的，基于设备的，基于数据集的或基于工作负载的时间限制字段中设置I / O请求时间限制值系统。扫描例程将I / O请求的总时间（包括等待时间和重试时间）与适当的时间限制进行比较，如果超过时间限制，则终止I / O请求。如果由于I / O错误导致活动I / O请求中断，如果总I / O请求时间（包括重试时间）超过适当的时间限制，或者在适当的时间限制范围内，则禁止重试时限。

摘要： Control unit level reset operations in systems having switched point-to-point I/O interface topologies is accomplished by determining and storing channel path identification numbers (CHPID's) and control unit link addresses (CULA's) for each device in the system, scanning this stored data to find devices whose CHPID's and CULA's match the CHPID and CULA for a device or a control unit having a reported error, quiescing devices with such matching CHPID's and CULA's, issuing a control unit level reset command and reactivating the quiesced devices. For systems having both multidropped and switched point-to-point topologies, provision is made for preliminarily determining whether a given control unit reset can be performed on the control unit level.

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a channel path and partial control unit link address, or a channel path and full control unit link address, may be originally made accessible, or may be restored to the I/O system.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： Apparatus and accompanying methods for use in preferably a multi-system shared data (sysplex (5)) environment which quickly and efficiently isolates (fences), through a pre-defined hierarchical order, failed sysplex components from accessing shared data in order to protect data integrity. Specifically, by dividing a sysplex workload into specified fence groups (FG A, FG B) and providing appropriate software and hardware fence support, fencing can occur at various distinct levels: a member-to-member level, i.e. to allow any member (220, 225, 230, 233,237) of a fence group to fully isolate any other ("target") member of that same group; a fence group level, i.e. to isolate all members of a fence group that execute on a "target" system (200.sub.1, 200.sub.2, 200.sub.3); and a system level, i.e. to fully isolate an entire "target" system. Through pre-defined escalation rules (630), fencing can be escalated from a lower member level to a higher, group or system, level in the event a lower level fence can not be successfully imposed. Member level fencing is accomplished in software (1300, 1500); group and system level fencing is accomplished through dedicated hardware fencing facilities (44). An identifier (444, 464) uniquely designates each different fence group existing on a computer processing complex (CPC) (40.sub.1, 40.sub.2, 40.sub.3, 40.sub.M) in the sysplex over the life of that CPC. Advantageously, this technique eliminates erroneous back level fencing, significantly expedites fence processing and also greatly reduces a need for human intervention.
