摘要： A technique for handling hardware errors in a computing system, such as a data storage facility, while avoiding a system crash. An interface is registered with an operating system of the computing system to process hardware errors. When a hardware error is detected, the interface checks an error register to identify the adapter that likely causes the error, and quarantines, e.g., blocks off, the offending adapter from the computing system. The interface then notifies the operating system that the error has been handled, thereby causing the operating system to bypass a system crash that would otherwise occur. The interface can be provided as a kernel extension of a device driver associated with the operating system.

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： 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： A method for modeling requirements of a product includes defining an abstract use case for each feature of said product; hierarchically decomposing each abstract use case until concrete use cases are specified for each feature; depicting every actor who would use said product as communicating with a concrete use case through a boundary; and programmatically extracting requirements from said use case diagram. Programmatically extracting requirements further includes converting use case diagrams into directed acyclic graphs, wherein each use case corresponds to a node of a graph, and each relationship between a pair of use cases is represented by a directed edge between the corresponding pair of nodes in said graph, wherein a directed edge points from a parent node to a child node, converting said directed acyclic graph into a tree, and searching said tree to extract said requirements.
