问题描述

SnapCenter无法枚举SQL可用性组。

SnapCenter接口不会显示已存在的SQL可用性组、即使SnapCenter能够枚举每个节点上的磁盘也是如此。各个节点上的SCW作业日志显示如下日志条目：

GetPartitionForVolume: return remote partition of remote disk '<Drive Letter>' ... GetHostFileSystem: partition.DiskId = 'Disk ID>', partition.Server = <Remote Server> ... Error: Could not find disk for partition [DiskId: <DiskID>]

注意： 这些错误消息中的<Remote Server>指的不是本地服务器的节点。

单个节点上的SCSQL作业日志显示如下日志条目：

Resource: SELECT * FROM MSCLUSTER_RESOURCE WHERE Type = "Network Name" An unexpected error occurred while retrieving the Cluster Resource data. [Type:Network Name] The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)

此外、Windows系统事件查看器日志中可能还会出现如下事件：

DCOM was unable to communicate with the computer <Windows cluster name> using any of the configured protocols; requested by PID <PID> (C:\Program Files\NetApp\SnapCenter\SnapCenter Plug-in for Microsoft SQL Server\SmSqlServiceHost.exe).
