CSNAPC-989：如果SnapCenter没有文件系统、则LUN无法将现有LUN连接到主机。
问题描述
当SnapCenter尝试将没有文件系统的现有LUN连接到主机时、连接磁盘向导会显示Failed - Failed to connect disk No disk is found on all nodes 。
- *在SC外部创建新LUN时、由于以下错误、SC无法连接它：
Failed - Failed to connect disk No disk is found on all nodes.
- 在实际的Windows上，
Connect-SdStorage(带或不带--SharedDisk)的命令行可能会出现相同的错误Host: Connect-SdStorage : Failed to connect disk No disk is found on all nodes
- SCW 作业日志(C：\Program Files\Microsoft\Windows\job_logs SnapCenter的NetApp SnapCenter插件)显示如下行。
示例：
