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    327,631     54,731  16%      4        272,900
  dg04  2,751,981    451,981  16%      3      2,300,000
  dg05    589,737    289,737  49%      1        300,000
  dg07    982,850    182,850  18%      2        800,000

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
small (2k)
