清除 SCSI-3 永久保留

如果您有 Windows 集群、则即使所有集群主机都处于脱机状态、也需要删除仲裁磁盘的 SCSI-3 预留。

如果尝试将源 LUN 标记为外部磁盘，则会显示以下错误信息：

“错误：命令失败：指定的外部磁盘具有 SCSI 持久性预留。磁盘序列号： "6006016021402700787 、 BAC217B44E411" 。在创建导入关系之前，请使用“ storage disk remove-reservation ”命令清除预留。”

您可以使用storage disk remove-reservation以下命令删除 NetApp 控制器上仲裁磁盘的 SCSI-3 预留：

storage disk remove-reservation –disk disk_name

下面是一个代码片段，其中显示了此错误及其补救措施：
