摘要： A method, associated apparatus and program product for partitioning a plurality of interconnection elements among disjoint partitions of processors in a computer system so as to interconnect the processors within each of the disjoint partitions, and to isolate the processors in each interconnected partition from processors in the other partitions. The interconnection elements may be arranged into groups including node coupling elements and link coupling elements and in larger systems may include intermediate groups having intermediate coupling elements. The partitioning of the interconnection elements begins with the interconnection of processors in the largest disjoint partition and proceeds by connecting the successive largest processor partitions whose interconnection elements share a group with the interconnect elements used for the previously interconnected processor partitions until no such interconnect elements on shared groups remain, subsequently the process is repeated until all processors in the disjoint partitions are interconnected.

摘要： Adapters, which provide message communications capabilities in a multinode data processing network, are provided with a mechanism for indicating critical errors from which recovery may ultimately be possible. Error handling capabilities are incorporated which operate both globally and locally to insure, to the greatest extent possible, that applications running on the network are not prematurely terminated and that the node with the error affected adapter is not prematurely removed from its connectivity with the other nodes within it network group.

摘要： A method, and a system for implementing the method, for implementing the method, for determining if a wire has been miswired in a network comprising service nodes and switch elements. The method includes the steps of: (1) transmitting a transmission stream in an outbound route, (where this transmission stream includes one or more service node fields for one or more service nodes, one or more switch element fields for one or more switch elements connected to the one or more service nodes, and a port field for each the switch element); (2) if the transmission stream is received on a port at a the switch element different than a the port field for the switch element indicated by the transmission stream, then setting an error indicator in the transmission stream; (3) transmitting the transmission stream back to the one or more service nodes in a return route, where the one or more service nodes determine from the error indicator a miswired condition between the receiving switch element and a previous switch element or service node along the outbound route. The one or more service nodes can record, store and tabulate the miswired condition and one or more additional miswired conditions. The transmission stream can store the one or more switch element fields for the one or more switch elements and the port fields for each the switch element separately for a path comprising the outbound route and a path comprising the return route.

摘要： An apparatus for synchronizing operator commands with a failover process in a distributed system having a control workstation and a plurality of nodes. One of the nodes of the distributed system is designated a primary node and one of the nodes is designated a backup node. The backup node includes a backup daemon for performing a failover process if the primary node fails such that the backup node becomes the primary node. Shell scripts send a command string to be synchronized with the operation of the backup daemon from the control workstation to the backup node. The backup daemon is then checked to determine if the backup daemon is sleeping, and, in the event the backup daemon is sleeping, commands derived from the command string are enqueued in a work queue for processing by the backup daemon. The backup daemon is then awakened such that the derived commands in the work queue are processed. In the event that the backup daemon is busy, commands derived from the command string are failed, thereby synchronizing the derived commands with the processing of the backup daemon.

摘要： A system and method for preventing deadlock in a multiprocessor computer system executing instructions requiring multiple resources. The system detects potential deadlock situations where a multi-resource instruction is blocked from obtaining one of the resources. A multi-resource instruction global lock is provided that can be held by at most one processor. Upon conflict detection, the processor attempts to acquire the multi-resource instruction global lock and, if successful, resumes resource acquisition. The use of a global lock serializes multiple resource requests and assures that the processor holding the lock can eventually acquire all required resources without deadlock with another processor. The preferred embodiment acquires the global lock on an exception basis to minimize the overhead impact. However, an alternate embodiment which uses the global lock in each multiple resource instruction could also be implemented. Synonym detection logic is provided to detect the situation where a conflict is caused by address resolution to a synonymous lock by the processor.

摘要： An apparatus, system, and method are disclosed for performing an incremental resynchronization between two unrelated volumes when a third volume fails. The apparatus, system, and method include initiating registration of changed tracks; keeping track of bytes in flight activities between a local volume and an intermediate volume; recording the changed tracks in bitmaps at the local volume; stopping the recording of the changed tracks; and starting a resynchronization process by sending the changed tracks to a recovery volume.

摘要： A two-phase process FlashCopy operation is provided that can be used to aid in the formation of consistency groups across multiple storage control units. In the first phase, preparations to create a new consistency group are made “revertible” by write-inhibiting the source volumes through “Establish-FlashCopy-revertible” commands. If the preparation of any volume within the consistency group fails, a “Withdraw-FlashCopy-revert” command may be executed, thereby causing a retention of the prior FlashCopy point-in-time copy. In the second phase, executed if all preparations are successful, a “Withdraw-FlashCopy-commit” command may be executed to remove all write-inhibit indicators, complete the creation of the new FlashCopy point-in-time copy and secure the new consistency group. Write requests to the FlashCopy source volumes may then be received and processed without risking corruption of the new consistency group on the Flashcopy target volumes.
