摘要： A method and system performs fencing techniques in a host cluster storage environment. A fencing application program interface resides in one or more storage systems. When a message is received by said storage system from a cluster member, the storage system in turn modifies the NFS export lists of one or more storage systems to restrict further access by the failed cluster node to otherwise fence the failed cluster node off from that storage system or from certain directories within that storage system. Prior to said access permission rights being changed, NFS operations are locked and drained, NFS locks are removed after which the export lists are modified. Once the fencing operations are performed, the NFS operations are served again by the storage system.

摘要： A method and system performs a fencing technique in a host cluster storage environment. The fence program executes on each cluster member in the cluster, and the cluster is coupled to a storage system by a network. When a cluster member fails or cluster membership changes, the fence program is invoked and a host fencing API message is sent via the network to the storage system. The storage system in turn modifies export lists to restrict further access by the failed cluster node to otherwise fence the failed cluster node off from that storage system or from certain directories within that storage system.

摘要： A host-clustered networked storage environment includes a “quorum program.” The quorum program is invoked when a change in cluster membership occurs, or when the cluster members are not receiving reliable information about the continued viability of the cluster, or for a variety of other reasons. When the quorum program is so invoked, the cluster member is programmed to assert a claim on a quorum device configured in accordance with the present invention. More specifically, the quorum device is a vdisk embodied in as a logical unit (LUN) exported by the networked storage system. The LUN is created as a quorum device upon which a SCSI-3 reservation can be placed by an initiator. Thus, the LUN is created for this purpose as a SCSI target that exists solely as a quorum device. Fencing techniques are also provided in the networked environment such that failed cluster members can be fenced from given—exports of the networked—storage system.

摘要： The present invention provides an improved method and system for real-time monitoring, validation, optimization and predictive fault analysis in a process control system. The invention monitors process operations by continuously analyzing sensor measurements and providing predictive alarms using models of normal process operation and statistical parameters corresponding to normal process data, and generating secondary residual process models. The invention allows for the creation of a fault analyzer directly from linearly independent models of normal process operation, and provides for automatic generation from such process models of linearly dependent process models. Fuzzy logic is used in various fault situations to compute certainty factors to identify faults and/or validate underlying assumptions. In one aspect, the invention includes a real-time sensor data communications bridge module; a state transition logic module; a sensor validation and predictive fault analysis module; and a statistical process control module; wherein each of the modules operates simultaneously.
