在外部 LUN 导入（ Foreign LUN Import ， FLI ）过程中，您应验证主机上是否已配置多路径并正常运行。

对 ESXi 主机完成以下步骤。

步骤

使用 VMware vSphere Client 确定 ESXi 和虚拟机。
确定要使用 vSphere Client 迁移的 SAN LUN 。

确定要迁移的 VMFS 和 RDM （ vfat ）卷： esxcli storage filesystem list

如果 VMFS 具有扩展 \ （跨区 VMFS\ ），则应迁移跨区中的所有 LUN 。要在图形用户界面中显示所有扩展，请转到 " 配置 ">" 硬件 ">" 存储 " ，然后单击数据存储库以选择 " 属性 " 链接。

迁移后，在将其重新添加到存储时，您将看到多个具有相同 VMFS 标签的 LUN 条目。在此情景中，您应要求客户仅选择标记为 HEAD 的条目。

确定要迁移的 LUN 和大小： esxcfg-scsidevs -c

确定要迁移的原始设备映射（ Raw Device Mapping ， RDM ） LUN 。

查找 RDM 设备： ` find /vmfs/volumes -name **-rdf+`

/vmfs/volumes/53843dea-5449e4f7-88e0-00262d04d700/Windows2003/Windows2003_1-rdmp.vmdk
/vmfs/volumes/53843dea-5449e4f7-88e0-00262d04d700/Windows2003/Windows2003_2-rdm.vmdk
/vmfs/volumes/53843dea-5449e4f7-88e0-00262d04d700/Linux/Linux_1-rdm.vmdk
/vmfs/volumes/53843dea-5449e4f7-88e0-00262d04d700/Solaris10/Solaris10_1-rdmp.vmdk

从上述输出中删除 -rdmp 和 -RDM ，然后运行 vmkfstools 命令以查找 VML 映射和 RDM 类型。

# vmkfstools -q /vmfs/volumes/53843dea-5449e4f7-88e0-00262d04d700/Windows2003/Windows2003_1.vmdk

直通是物理 \ （ RDMP\ ）的 RDM ，非直通是虚拟 \ （ RDMV\ ）的 RDM 。由于 VM Snapshot 增量 vmdk 指向具有陈旧 naa ID 的 RDM ，具有虚拟 RDM 和 VM Snapshot 副本的 VM 将在迁移后中断。因此，在迁移之前，请客户删除此类 VM 中的所有 Snapshot 副本。右键单击 VM ，然后单击 Snapshot -\> Snapshot Manager Delete All 按钮。有关在 NetApp 存储上对 VMware 进行硬件加速锁定的详细信息，请参见 NetApp 知识库 3013935 。

确定 LUN naa 到 RDM 设备的映射。

确定多路径配置。
在 vSphere Client 中获取存储的多路径设置：
1. 在 vSphere Client 中选择 ESX 或 ESXi 主机，然后单击配置选项卡。
2. 单击 * 存储 * 。
3. 选择数据存储库或映射的 LUN 。
4. 单击 * 属性 * 。
5. 在属性对话框中，根据需要选择所需的块区。
6. 单击 * 块区设备 * > * 管理路径 * ，然后在管理路径对话框中获取路径。

从 ESXi 主机命令行获取 LUN 多路径信息：

登录到 ESXi 主机控制台。

运行 esxcli storage nmp device list 以获取多路径信息。
