How to find SAN LUN Mapped to VxVM Disk in Linux
|
||||
如何在 Linux 中查找映射到 VxVM 磁盘的 SAN LUN
|
||||
======
|
||||
|
||||
We’ve written several articles in the past to find LUN ID mapped to Block device/disk, but when you’re managing a **[VCS cluster][1]** there are some situations where you might want to map a LUN ID against a VxVM (Veritas Volume Manager ) disk for VxFS file system expansion.
|
||||
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。
|
||||
|
||||
This short article describes how to find the LUN number associated with a VxVM disk in Linux
|
||||

### Shell Script to find LUN Number Mapped to VxVM Disk in Linux
|
||||
### 在 Linux 中查找映射到 VxVM 磁盘的 LUN 号的 Shell 脚本
|
||||
|
||||
This handy shell script helps you to identify which storage LUN associated to which VxVM disk on Linux.
|
||||
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。
|
||||
|
||||
#### How this script works
|
||||
#### 这个脚本是如何工作的
|
||||
|
||||
This script follow the below steps to collect and print these information’s.
|
||||
该脚本按照以下步骤收集和打印这些信息。
|
||||
|
||||
* It collects the list of active **‘Disk Group’ (DG)** on the system
|
||||
* Find the **‘Device Names’** associated with the respective DGs.
|
||||
* Next, it lists the **‘Block Devices’** mapped with the respective devices.
|
||||
* Finally collects the **LUN IDs** associated with these block devices and prints them all together like DG name, block device name and LUN numbers.
|
||||
* 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”**。
|
||||
* 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。
