摘要： A method and mechanism for generating a snapshot in a computing system. On initiating a snapshot of a first storage, the content of a portion of the first storage that includes at least one block is copying to snapshot storage and a copied indication for each copied block is recording in a copy map. Responsive to any write request to a block for which no copied indication has been recorded in the copy map, the content of the block is copied to the snapshot storage, prior to writing to that block. The content of other blocks for which no copied indication has been recorded in the copy map is successively copied to the snapshot storage. A copied indication for each copied block is recorded in the copy map. The successive copying can be performed as a background task.

摘要： A device driver (GRAPHICS, NETWORK, H2IO, IO2L, SERIAL) for use in a computer system comprising a processor (P), memory (M) and a device (GRAPHICS, NETWORK, H2IO, IO2L, SERIAL) operatively coupled to the computer system, the device driver being operable to control the device to monitor an operational status of the device, and consequent upon a change in the operational status to generate a fault report data indicating whether the change of status was caused internally within the device or externally by another connected device which caused the change of operational status to occur. The fault reports may also include an indication of the operational status of the device. Furthermore, if the fault report data indicates that the change of status was caused externally, the device driver may generate fault direction information indicative of an apparent direction on a connection between the device and the other device suspected as causing the indicated external fault. By providing an indication as to whether a fault has occurred internally or externally, and if externally, a relative direction on a data path from which the fault is perceived, a fault response processor can estimate the location of a faulty device of the computer system with improved accuracy.

摘要： A computer system compnses a processor (2), memory (4) and a plurality of devices (6, 8, 12), the processor (2) and the memory (4) being operable to effect the operation of a fault response processor (AFR), and a device driver (GRAPHICS, NETWORK, H2IO, IO2L, SERIAL) for each of the devices. The fault response processor (AFR) is operable to generate a model which represents the processor (2), the memory (4) and the devices (6, 8, 12) of the computer system and the inter-connection of the processor (2), memory (4) and the devices (GRAPHICS, NETWORK, H2IO, IO2L, SERIAL). The device driver (GRAPHICS, NETWORK, H2IO, IO2L, SERIAL) for each of the devices (6, 8, 12) is arranged, consequent upon a change of operational status of the device, to generate fault report data indicating whether the change of status was caused internally within the device or externally by another connected device. The devices of the computer system may be formed as a plurality of Field Replaceable Units (FRU). The fault response processor (AFR) is operable, consequent upon receipt of the fault reports from the device drivers (GRAPHICS, NETWORK, H2IO, IO2L, SERIAL) to estimate the location of a FRU containing a faulty device by applying the fault indication to the model. In other embodiments the fault report data includes direction information indicating a connection between the device and the other connected device which caused the external fault. Having identified the faulty device the FRU may be replaced, thereby minimizing down time of the computer system.
