Abstract: 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.

Abstract: 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.

Abstract translation: 方法和系统在主机群集存储环境中执行击剑技术。 围栏程序在群集中的每个群集成员上执行，群集通过网络耦合到存储系统。 当集群成员发生故障或集群成员身份更改时，将调用fence程序，并通过网络将主机防护API消息发送到存储系统。 存储系统又会修改导出列表，以限制故障集群节点的进一步访问，以便将故障集群节点从该存储系统或该存储系统内的某些目录中脱离。
