摘要： Provided are a method, system, and program for configuring shared devices over a fabric. A module in a first processing complex configures a first part of a fabric enabling communication with a set of devices accessible through the first part of the fabric. The module detects a located device accessible through a second part of the fabric, wherein a second processing complex is designated to configure the second part of the fabric and the located device. The module determines whether the second processing complex is available in response to detecting the uninitialized device. The module passes to a device driver in the first processing complex an uninitialized property for the located device. The device driver requests the module to configure the second part of the fabric to enable access to the located device over the second part of the fabric in response to determining that the located device has the uninitialized property.

摘要： Provided are a method, system, and program for handling a fabric failure. A module intercepts a signal indicating a failure of a path in a fabric providing a connection to a shared device. The module generates an interrupt to a device driver in an operating system providing an interface to the shared device that is inaccessible due to the path failure. The device driver requests information from the module on a status of a plurality of devices that are not accessible due to the path failure and receives information indicating the inaccessible device. The device driver reconfigures to discontinue use of the inaccessible device.

摘要： A determination is made as to whether a configuration indicator associated with a resource indicates a delayed configuration of the resource, wherein the resource is shared by a plurality of processing complexes via a bus, and wherein if the delayed configuration of the resource is indicated then the resource is prevented from being configured during initial program loads of the plurality of processing complexes. The resource is configured by only one of the of plurality of processing complexes that shares the resource, in response to determining that the configuration indicator associated with the resource indicates the delayed configuration of the resource.

摘要： A delay interval is calculated for a processor that attempts to reserve a reserved shared resource in a multiprocessing system. The delay interval is based on the relationship of a requesting processor and a reservation holding processor. Each delay interval is unique without consistent bias against a processor. The requesting processor queries the reservation status of a shared resource without invalidating an existing reservation. If a shared resource is reserved, the requesting processor waits for an amount of time corresponding to the delay interval before again attempting to reserve the shared resource. The present invention substantially reduces arbitration conflicts within multiprocessor systems.

摘要： Processor(s) operating a random access memory is subject to reboot processing which comprises clearing the random access memory. Registration is provided of a portion of the random access memory, the registration indicating that data stored in the registered portion of the random access memory is to be preserved during the reboot processing. In reboot processing, the processor responds to the registration, preventing data stored in the registered portion from clearing during the reboot processing.
