摘要： Provides a software-to-software interface and a software-to-hardware interface between software users and a hardware ADM facility (ADMF) in a data processing system. Such software user presents only virtual addresses to the software-to-software interface in a MSB list. The user list defines virtual address spaces, including a "hiperspace", in a manner that represents physical backing media as different random-access electronic storages, such main storage (MS) and expanded storage (ES). The real data transfers are within or between the backing storages. The user list is transformed into an ADM operation block (AOB), which is assigned an ADM UCB in a UCB queue which is associated with an ADM subchannel. The software-to-hardware interface generates an ORB, containing the AOB address, as an operand of a SSCB instruction which is executed to queue the associated subchannel onto one of plural co-processor queues in the ADMF. The ADMF uses the AOB to perform the requested page moves, and generates an interruption upon completion of each request which is sent to the hardware-to-software interface to remove the associated ADMF request from the ADM software request queue and free the associated ADM UCB for use by another user request.

摘要： A switching error detection and recovery mechanism recognizes that an I/O configuration has changed. Comparing new configuration data to previous data maintained in a CDT table structure, and detecting unequal path information, an error condition is recognized. After recognizing the error condition, recovery actions are taken to notify the operator and insure data integrity. The CDT is structured so that redundant data is eliminated, and so records may be efficiently and dynamically added and deleted.

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： A computer system includes memory divided into a plurality of logical partitions (LPARs), each LPAR running one of a plurality of instances of an operating system (O/S). The system also includes a processor configured to run a hypervisor program to manage operation of the plurality of LPARs. The processor determines a reference I/O service time of an I/O operation on a server, measures an actual I/O service time of the operation, and determines a delay time of virtualization on the server based on the reference I/O service time and the actual I/O service time.
