1.用ioscan -fnC disk | more区分内外部硬盘

2.查看PE的大小

test01#[/] vgdisplay | grep "PE Size"
PE Size (Mbytes) 16
PE Size (Mbytes) 16
PE Size (Mbytes) 4
PE Size (Mbytes) 16

3.查看剩余的PE

test01#[/] vgdisplay | grep "Free PE"
Free PE 2184
Free PE 323
Free PE 1760
Free PE 413

4.算出外部硬盘剩余空间的大小

排除内部硬盘的Free PE和 PE Size
把剩下的一一对应相乘，最后相加就能得到外部硬盘剩余空间的大小

[PE Size (Mbytes) 16] * [Free PE 2184] //内部硬盘排除//
[PE Size (Mbytes) 16] * [Free PE 323]
[PE Size (Mbytes) 4] * [Free PE 1760]
[PE Size (Mbytes) 16] * [Free PE 413]
