Description

This script parses the output of "vxprint -A" which is part of the Veritas Volume Manager and displays a summary of the obtained information.
The resulting output will look similar to this:

    dg    size(MB)  avail(MB) in%  volume(s) lgv-space(MB)
  dg01     32,750        750   2%      2         32,000
  dg02    212,876     32,261  15%     75        180,448
  dg03    163,751     21,186  12%     66        142,524
  dg04    163,751         68   0%     49        163,644
  dg05    196,501      8,941   4%     40        187,520

Column description

dg	The diskgroup.
size	The size of the diskgroup in MB*.
avail	The available diskspace in MB*.
in%	The available diskspace in percent.
volume(s)	The number of defined logical volumes.
lgv-space	The amount of diskspace made available in logical volumes.
	*)1MB = 2^20 bytes

If you have lots of volumes (as in this case) you will notice that "lgv-space"+"avail" doesn't always add up to "size". That is normal as the logical volume definitions themselves have to be stored somewhere too...

The major plus points are:

doesn't require privileged access
doesn't depend on any additional Perl modules
runs very fast (less than a second)
no parameters
