如何在 Linux 中查找映射到 VxVM 磁盘的 SAN LUN
|
||||
======
|
||||
|
||||
我们过去写过几篇文章来查找映射到块设备/磁盘的 LUN ID，但是当你管理 **[VCS 集群][1]**时，在某些情况下你可能需要映射 LUN 用于 VxFS 文件系统扩展的 VxVM (Veritas Volume Manager) 磁盘的 ID。

### 在 Linux 中查找映射到 VxVM 磁盘的 LUN 号的 Shell 脚本
|
||||
|
||||
这个方便的 shell 脚本可帮助你识别哪个存储 LUN 与 Linux 上的哪个 VxVM 磁盘关联。

这个方便的 Shell 脚本可帮助你识别哪个存储 LUN 与 Linux 上的哪个 VxVM 磁盘关联。
|
||||
|
||||
#### 这个脚本是如何工作的
|
||||
|
||||
该脚本按照以下步骤收集和打印这些信息。
|
||||
|
||||
* 它收集系统上活动**“磁盘组”(DG)**的列表
|
||||
* 查找与相应 DG 关联的**“设备名称”**。
|
||||
* 接下来，它列出了与各个设备映射的**“块设备”**。

|
||||
* 查找与相应 DG 关联的 “设备名称”。
|
||||
* 接下来，它列出了与各个设备映射的 “块设备”。
|
||||
* 最后收集与这些块设备关联的 **LUN ID** 并将它们全部打印在一起，如 DG 名称、块设备名称和 LUN 编号。

sh VxVM_disk_mapping_with_LUN_number.sh
|
||||
```
|
||||
|
||||
你的输出将类似于此。但是，DG 名称、块设备和 LUN 会与此不同。
