Abstract: In a computing device that performs synchronization testing of a plurality of active clustered servers, a request to check synchronization between slave data stored and master data is received. The request includes master synchronization test values computed by a master node that include a number of records included in a dataset and a sum of modification time values for the records. Slave synchronization test values are computed that include a number of records included in the dataset of the slave data and a sum of modification time values for the records in the dataset of the slave data. The computed slave synchronization test values are compared to the master synchronization test values. A message is sent to the requesting device indicating the slave node is synchronized when the computed synchronization test values match or indicating the slave node is not synchronized when the computed synchronization test values do not match.

Abstract: Data lifecycle management is performed by managing metrics from a monitored system. A fault is identified from the monitored system. One or more metrics that are directly related to the fault and one or more metrics that are indirectly related to the fault by virtue of being directly or indirectly related to the one or more directly related metrics are identified and stored in a memory. A lifespan condition associated with the fault is identified. A lifespan for each of the directly and indirectly related metrics based on the identified lifespan condition is added or changed. A metric that is critically related to another metric will inherit the same lifespan, and a metric that is related but not critically related to another metric will not inherit the other metric's lifespan. Metrics are removed from the memory if their associated lifespans are over.

Abstract: Techniques are provided for performing automated operations to enable first-failure data capture functionality during initialization of multiple lockstep processors. Following a hardware reset of two lockstep processors, an indication is received of one or more crosscheck errors regarding the operation of the two lockstep processors. In response to the crosscheck errors, crosscheck first-failure data capture (FFDC) data is saved to one or more memory areas that are persistent across a hardware reset, and it is determined whether a predefined reset threshold has been satisfied. Responsive to determining that the predefined reset threshold has been satisfied, the crosscheck FFDC data from the one or more persistent memory areas is analyzed and one or more crosscheck initialization codes are responsively generated. An additional hardware reset is initiated.

Abstract: A system and method are provided for failure management for electronic transactions. An access request is received at a first server and from a client device, for a second server. The first server determines whether the second server is functional. If the second server is non-functional, the access request is stored in a storage associated with the first server. The second server is monitored until becoming functional. During the monitoring, a status request from the client device may be received and responsive to the status request, a status update is sent to the client device. Upon determining the second server is functional, the access request is sent to the second server, a response to the access request is received from the second server, and the response is sent to the client device.

Abstract: Managing storage volumes in a point-in-time copy cascade. The cascade includes a first source volume, a first clone point-in-time target volume, and a second point-in-time target volume that is a point-in-time copy of the first point-in-time target volume. Grain background copies from the first source volume to the first clone point-in-time target volume are tracked, and, if the first clone point-in-time target volume is corrupted, a third point-in-time target volume is created from the second point-in-time target volume. I/O for the first clone point-in-time target volume is directed to the third point-in-time target volume. The first clone point-in-time target volume is cleaned to the second point-in-time target volume. The first clone point-in-time target volume is restarted from the third point-in-time target volume and each grain of the first clone point-in-time target volume that has not been background copied is copied from the cascade to the first clone point-in-time target volume.

Abstract: A method and related apparatus are provided for restoring a connection through a provider network (PN). In particular, a connection is established along a path (P1) through the provider network (PN) for the transport of client traffic between two client network nodes (CR1, CR2) of a client network (CD1, CD2). Any restoration service for this connection is deactivated. However, when a failure (F1) is detected along the path (P1) which affects the connection, a path search is performed anyhow to determine a projected restoration path (P2) through the provider network (PN) available to restore said failed connection. In the case that the path search was successful and a projected restoration path (P2) was found, the availability of the projected restoration path (P2) is communicated (MS1, MS2) to the client network (CD1, CD2). The client can now decide whether to accept a temporary service upgrade to restoration service or not.

Abstract: A load driving device including a converter, an output circuit and a timer circuit is provided. The converter receives a communication frame including a data signal through a serial communication and performs parallel conversion on the data signal to output an instruction signal instructing the output circuit to transition to a first state when the data signal includes first serial data and output an instruction signal instructing the output circuit to transition to a second state when the data signal includes second serial data. A timer circuit measures a duration time during which the converter receives the first serial data. When the measuring duration time arrives at an abnormality determination time, the timer circuit forces the output circuit to transition to the second state when the measuring duration time arrives at an abnormality determination time.

Abstract: Managing storage volumes in a point-in-time copy cascade. The cascade includes a first source volume, a first target volume and a second target volume. The method detects a corruption of the first source volume and, if a first restoration of the first source volume from the first target volume is in progress, creates a third target volume from the second target volume and directs I/O operations for the first source volume to the third target volume. The first restoration is stopped. The first source volume is restored from the third target volume, and the third target volume is deleted.

Abstract: A system and method for remote maintenance of user units allows efficient diagnosis of failures in a reduced time. Each user unit transmits to a management server, via a network, state data related to hardware and software parameters associated to an operating mode of the user unit. The method includes: storing state data in a user unit memory, monitoring state data stored in the memory, and detecting at least one datum of a state indicating an operational failure of the user unit. When a failure is detected, state data corresponding to current states of the user unit at the moment of the failure and state data corresponding to states stored during a predetermined period before the failure are extracted and transmitted to the management server which determines a statistic correlation coefficient between the values of each state of a user unit and the values of states of other user units.

Abstract: When the mirrored point in time copy fails, at that point in time all the data for making the source and target of the point in time copy consistent is available on secondary volumes at disaster recovery site. The data for the source and target of the failed point in time copy are logically and physically equal at that point in time. This logical relationship can be maintained, and protected against ongoing physical updates to the affected tracks on the source secondary volume, by first reading the affected tracks from the source secondary volume, copying the data to the target secondary volume, and then writing the updated track to the source secondary volume.
