SnapCenter UI：

对受影响的卷运行ONTAP命令行界面命令"File-Directory show"将返回以下错误：

<Cluster_Name>::*> File-directory show -vserver <SVM_Name> -path <Volume_Path>

(vserver security file-directory show)

Error: show failed: The specified path "<Volume_Path>" cannot be used. Reason: No such file or directory.

在ONTAP系统管理器中查看受影响的卷时、不会显示任何文件或目录、并显示以下错误：

No such file or directory
