Abstract: Methods and systems for port reachability are provided. The process obtains an identifier for ports of a broadcast domain to access storage space at a clustered storage system; sends a discovery request to the ports of the broadcast domain; receives a response to the discovery request from some or all the ports; places ports that responded to the discovery request to a first group that indicates that all ports within the group are reachable; and reports ports within the first group to a user to indicate which ports within the broadcast domain are reachable.

Abstract translation: 提供了端口可达性的方法和系统。 该过程获得广播域的端口的标识符，以访问集群存储系统的存储空间; 向广播域的端口发送发现请求; 从一些或所有端口接收对发现请求的响应; 将响应发现请求的端口放置到第一个组，指示组中的所有端口可达; 并将第一组内的端口报告给用户以指示广播域内的哪些端口可达。

Abstract: One or more techniques and/or systems are provided for cluster configuration information replication, managing cluster-wide service agents, and/or for cluster-wide outage detection. In an example of cluster configuration information replication, a replication workflow corresponding to a storage operation implemented for a storage object (e.g., renaming of a volume) of a first cluster may be transferred to a second storage cluster for selectively implementation. In an example of managing cluster-wide service agents, cluster-wide service agents are deployed to nodes of a cluster storage environment, where a master agent actively processes cluster service calls and standby agents passively wait for reassignment as a failover master in the event the master agent fails. In an example of cluster-wide outage detection, a cluster-wide outage may be determined for a cluster storage environment based upon a number of inaccessible nodes satisfying a cluster outage detection metric.

Abstract translation: 提供了一个或多个技术和/或系统用于集群配置信息复制，管理集群范围的服务代理和/或用于集群范围的中断检测。 在集群配置信息复制的示例中，可以将与为第一集群的存储对象（例如，卷的重命名）实现的存储操作相对应的复制工作流传送到第二存储集群以进行选择性实现。 在管理集群范围的服务代理的示例中，将集群范围的服务代理部署到集群存储环境的节点，其中主代理程序主动处理集群服务调用和备用代理程序被动地等待重新分配为故障转移主服务器， 主代理失败。 在群集范围的中断检测的示例中，可以基于满足群集中断检测度量的多个不可访问的节点来为群集存储环境确定群集范围的中断。
