1、用cfgmgr -v 命令进行搜索新硬件的操作。
2、用lspv命令确认扫描到的新硬盘。
3、如果需要删除硬盘，用rmdev -dl hdisx 命令进行删除。

三、部分常用命令 ----------------
显示 hdisk2 的逻辑卷分配图： lslv -p hdisk2 显示所有活动的卷组名： lsvg -o 显示卷组 vg02 中的所有逻辑卷的名称、特性和状态： lsvg -l vg02 使卷组 vg03 在系统启动期间自动激活： chvg -a y vg03 如果违背每个物理卷限制的 1016 个物理分区来将卷组 vg03 更改为受支持的状态： chvg -t vg03 将每个物理卷的物理分区的最大数更改为 2032，将卷组 vg03 中的物理卷的最大数更改为 16： chvg -t 2 vg03
