How to map SAN LUN, Disk and FileSystem in Linux
如何在 Linux 中映射 SAN LUN、磁盘和文件系统
======
For some requirements, you may need to find a block device mapped against a logical unit number (LUNs) and filesystem (FS) for FS expansion or disaster recovery (DR) activity.
对于某些需求，你可能需要找到映射到逻辑单元号 (LUN) 和文件系统 (FS) 的块设备，以进行文件系统扩展或灾难恢复 (DR) 活动。
Similar activity may happens frequently when you are managing the bigger infrastructure. Let’s say, more than 1000+ servers hosting various applications.
当你管理更大的基础设施时，类似的活动可能会经常发生。假设有超过 1000 台服务器托管各种应用。

**Make a Note:** In the above output, device sda won’t show any LUN info because it’s a virtual disk added from VMWare end, which doesn’t have any LUN. Other 3 disks are mapped from Storage that’s why we are able to see LUN info.
**注意：** 在上面的输出中，设备 sda 不会显示任何 LUN 信息，因为它是从 VMWare 端添加的虚拟磁盘，没有任何 LUN。其他 3 个磁盘是从存储映射的，这就是我们能够看到 LUN 信息的原因。
