Wherein a determination that the event is an incident cannot be made after comparing the target state and the current state, the system automation module compares the current state to the current state prior to the event. Upon determining that the event is an incident, the event data is marked and stored in a repository.

Abstract: A wireless communications device may be configured to perform integrity checking and interrogation with a network entity to isolate a portion of a failed component on the wireless network device for remediation. Once an integrity failure is determined on a component of the device, the device may identify a functionality associated with the component and indicate the failed functionality to the network entity. Both the wireless network device and the network entity may identify the failed functionality and/or failed component using a component-to-functionality map. After receiving an indication of an integrity failure at the device, the network entity may determine that one or more additional iterations of integrity checking may be performed at the device to narrow the scope of the integrity failure on the failed component. Once the integrity failure is isolated, the network entity may remediate a portion of the failed component on the wireless communications device.

Abstract: Methods for monitoring operating statuses of hosts are described herein. Operating statuses for one or more hosts are monitored by a management server over a network using a network management protocol. In response to a failure to obtain an operating status of a first host over the network using the network management protocol, the management server instructs a second host to access a predetermined storage location to obtain the operating status of the first host. The predetermined storage location is specifically allocated for the first host from a storage space shared by all the hosts. Thereafter, the management server is configured to determine an operating condition of the first host based on the operating status obtained via the second host.

The job execution infrastructure maintains the state information for all the executing jobs, and the job control units, one per-job, control the state transitions of their jobs. Due to the stateless nature of the control units, the system and method allow jobs to continue uninterrupted execution even when the corresponding control units fail.

The second path includes a second initiator endpoint and a second target endpoint and is identified by selecting a path from among those paths that have at least one endpoint that is different from the two endpoints of the first path.

Abstract: Upon starting the initial copy process, a pair creation command is issued from a primary disk subsystem to a secondary disk subsystem. The secondary disk subsystem sets a target area of a second disk drive to an unwritten status, and thereafter writes update data that was updated in a primary site into a designated area of the second disk drive. Subsequently, when data of a first disk drive is backed up to an external medium, the external memory medium is transported to a secondary site, and then connected to a host computer. Unwritten data among the backup data recorded in the external memory medium is thereafter restored to the first disk drive, and the initial copy is completed on the condition that all data in the first disk drive has been copied to the second disk drive.

Abstract: A system implementing parallel memory error detection and correction divides data having a word length of K bits into multiple N-bit portions. The system has a separate error processing subsystem for each of the N-bit portions, and utilizes each error processing subsystem to process the associated N-bit portion of the K-bit input data. During memory write operations, each error processing subsystem generates parity information for the N-bit data, and writes the N-bit data and parity information into a separate memory array that corresponds to the error processing subsystem. During memory read operations, each error processing subsystem reads N-bits of data and the associated parity information. If, based on the parity information, an error is detected from the N-bit data, the error processing subsystem attempts to correct the error. The corrected N-bit data from each of the error processing subsystems are combined to reproduce the K-bit word.

Abstract: A data processing apparatus and method are provided that use monitoring circuitry to control operating parameters of the data processing apparatus. The data processing apparatus has functional circuitry for performing data processing, the functional circuitry including error correction circuitry configured to detect errors in operation of the functional circuitry and to repair those errors in operation. Tuneable monitoring circuitry monitors a characteristic indicative of changes in signal propagation delay within the functional circuitry and produces a control signal dependent on the monitored characteristic. In a continuous tuning mode operation, the tuneable monitoring circuitry modifies the dependency between the monitored characteristic and the control signal in dependence upon certain characteristics of the errors detected by the error correction circuitry.

Abstract: An application can specify reliability values via a communication path between the application and the registers. Application reliability could increase if the application itself could specify the timeout and retry values. For instance, some errors might be prevented if the timeout value is lengthened by a short amount. A longer timeout value would result in slower performance because the memory component could not be accessed during the timeout period. However, resolving errors in memory devices would prevent unrecoverable error indicators from being returned to the application, which would in turn limit application and system crashes.

The backup module restores the service flows of the cable modems based on a restoration order determined by session recovery priorities that are related to quality of service levels required by the service flows. In particular, service flows that are engaged in VoIP “911” calls are restored first. Service flows engaged in other VoIP calls are next restored. Lastly, service flows engaged in regular data sessions are restored.
