    摘要： Technical solutions are described for executing a plurality of computer-executable synchronous input/output (I/O) commands received by a storage control unit in a multiple virtual storage system. An example method includes receiving a set of synchronous I/O commands, each of the commands received from a respective operating system from a plurality of operating systems. The method further includes selecting, from the set of synchronous I/O operations, a subset of synchronous I/O commands, and allocating a shared resource to the subset of synchronous I/O commands. The method further includes executing each synchronous I/O command from the selected subset of synchronous I/O commands concurrently.

    摘要： Aspects include sending a request to perform a unit of work that includes a synchronous I/O operation. The sending is from an operating system (OS) executing on a server to firmware located on the server. The synchronous I/O request includes a command request block that includes an operation code identifying the synchronous I/O operation and a identifier of a persistent storage control unit (SCU). The OS waits for the synchronous I/O to complete and the unit of work remains active during the waiting. The firmware detects that the synchronous I/O operation has completed. A command response block that includes completion status information about the synchronous I/O operation is received by the OS from the firmware. The unit of work is completed in response to the I/O operation completing.

    摘要： An instruction is provided that includes an opcode field to identify a store instruction to store in a designated location current values of operational parameters of an adapter function of an adapter; a first field to identify a location, the contents of which include a function handle identifying a handle of the adapter function for which the store instruction is being performed, and an indication of an address space associated with the adapter function identified by the function handle to which the store instruction applies; and a second field to identify the designated location of where a result of the store instruction is to be stored. Execution of the instruction includes obtaining information from a function information block associated with the adapter function; and copying the information from the function information block into the designated location, based on completion of one or more validity checks with one or more predefined results.
