[olug] Multipath, multi-arrays, and correlation.

[Jay Swackhamer]

I could find a complete script with all of the info I needed, so I  
wrote the following script to print out:
sd-device | dm-device | mpath | Array model | volume group | size |  
serial number | device number


output sample:

sdff       | dm-37      | mpath55    | 2107900          | none       |  
19531264   | 75L86111189     | 130:16
sdfg       | dm-26      | mpath8     | HSV210           | vg02       |
