redhat – 从SAN安装磁盘(RHEL 5.9)

Linux 前端之家
前端之家收集整理的这篇文章主要介绍了redhat – 从SAN安装磁盘(RHEL 5.9)，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
存储管理员告诉我他从SAN上将3TB硬盘放在我的服务器上,然后我被要求安装它.我知道的唯一信息是它在LUN 1上,磁盘是3TB.

设置了多路径,我安装了QLogic驱动器.我不知道现在要做什么…有这么多磁盘我怎样才能找到正确的挂载？我告诉存储人我在SAN上看到了所有内容,但我从他那里得到了“我不懂Linux”.我不知道要问什么问题来弄清楚要安装的磁盘.

这是fsdisk -l的输出：

我以前从来没有做过这样的事情所以请不要打扰我.我只是在寻找哪些问题要求存储管理员,以及找到正确的驱动器进行格式化和安装的命令.

解决方法

不要使用/ dev / sd *,因为它们只映射到单个路径.

使用/ dev / mpath *设备(或由multipath -l的输出显示).

输出multipath -ll显示您要使用的磁盘是/ dev / mapper / mpath1

制作文件系统,格式化,分区或任何你喜欢的东西.只是不要使用/ dev / sd *设备.

看着你的输出,

组成mpath1的设备代表到同一磁盘的单个路径(multipathd通过查看WWID等来计算出来).这意味着输出中的所有sd *磁盘指向同一设备,但使用不同的路径来到达它.这是为了冗余和有时是性能的原因.
