清除 SCSI-3 持久预留

贡献者

如果您使用的是 Windows 集群，则需要删除仲裁磁盘的 SCSI-3 预留，即使所有集群主机均脱机也是如此。

如果尝试将源 LUN 标记为外部磁盘，则会显示以下错误消息：

 Error: command failed: The specified foreign disk has SCSI persistent reservations. Disk serial number: "6006016021402700787BAC217B44E411". Clear the reservation using the "storage disk remove-reservation" command before creating the import relationship.
您可以使用 `storage disk remove-reservation` 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

下面是一个显示此错误及其修复方法的代码片段：

cluster-4b::*> lun offline -vserver fli_cluster -path /vol/fli_volume/cluster_CVS
cluster-4b::*> lun import create -vserver fli_cluster -path /vol/fli_volume/cluster_CVS -foreign-disk 6006016021402700787BAC217B44E411
