Why not use something like IO::Pipe and get rid of awk completely. I suspect that the code below is 'not ideal' for example you very likely don't want/need a sub call to run_command I pass in system, protocol (rsh|ssh) and command in my case so it ate the sub call for some flexibility

#!/usr/bin/perl
use strict;
use warnings;
use IO::Pipe;

my @systems = ('3par-S400','3par-E200');
my $system = undef;
my $output = undef;
my $command = undef;

foreach $system (@systems) { 

    $output = run_command($system);



    while (<$output>) {
        next if (m/^$/);
        last if (m/^Press.*/)       
        #grab bits here instead of using awk
              
        
        
        
    
    }

    close($output);

}


sub run_command {

my $system = shift;
my $protocol = 'ssh';
my $command = "statvv -ni";
my $space = " ";
#The following is bad but it works for now..
my $do_command = $protocol . $space . $system . $space . $command; 
my $cmd = new IO::Pipe;
$cmd->reader($do_command);
return $cmd;
   
    
}
