注意：几个相关概念：
PV：物理卷，指的是一块独立的磁盘或者Raid里的逻辑卷，在AIX中由PVID唯一确定
VG：卷组，由一个或者多个PV组成；PV是组成卷组的最小单位，每个PV只能属于一个VG；不同类型的PV（如sata、sas、fc等）可以属于同一个VG；组成VG的多个PV可以不用连续排列
PP：物理分区，每个PV被分成容量一样大小的若干个PP；同一个VG里所有PV上的PP大小是相同的
LV：逻辑卷，每个VG划分成若干个LV在系统中使用，每个LV对应一个文件系统；LV可以建在一个PV上也可以建在同一个VG的多个PV上
LP：逻辑分区，每个LV有多个LP组成，每个LP对应至少一个PP，如果LV有镜像，则一个LP可能对应多个PP
