I am attempting to write a script that will gather stats from a 3par storage unit that does not run a unix like operating system. What I am attempting to do is ssh into the device with an ssh key and issue 3par commands to the unit and awk the results. I am trying to take the output and put them into various variables which I will then feed to gmetric to graph in ganglia. The problem is this: the 3par commands are continuous and only stop when you press the 'enter' key. Getting this data into a variable array would be easy but for the fact that the commands are continuous. Here's what I came up with, but this needs to be tweaked to take the above fact into account:

#!/usr/bin/perl
use strict;
use warnings;

#`/bin/echo "SNMP 3PAR DISK STATS start executed on: `date +%D' at '%l
+:%M:%S`" >> /var/log/snmp-3par-disk-stats.log`

push my @vluns,`ssh -l gmon 3par-S400 statvv -ni | awk '{print $1 }'`;
foreach my $vlun (@vluns) {
 if ($vlun ne "Press") {
   print "$vlun \n";
 }
 else {
 last;
 }
}


push my @vluns2,`ssh -l gmon 3par-E200 statvv -ni | awk '{print $1 }'`
+;
foreach my $vlun2 (@vluns2) {
 if ($vlun2 ne "Press") {
   print "$vlun2 \n";
 }
 else {
 last;
 }
}

But it keeps throwing this error:

[gmon@cc126-200 ~]$ ./3par-disk-stats.pl 
Use of uninitialized value in concatenation (.) or string at ./3par-di
+sk-stats.pl line 7.

It seems that it is choking on the $1 that I am passing to awk. I could use some help passing the right variable. Also this is a sample of the text I am trying to parse:

Press

16:34:19
VVname
mgmain_data
mgnote01_redo1
mgnote01_redo2
mgtool02_data_110G
mgtool02_redo1_3G
mgtool02_redo2_3G
mgnote01_data_85G
rcat11_data
racprod_redo1a_tpvv
racprod_redo1b_tpvv

And this is the output I would like to omit at the end:

----------------------------------------------------------------------
+---------------------
                   total   t 5766 5777      601349 585394         8.4 
+ 8.6 104.3 101.3   67
Press the enter key to stop...

But most importantly I am looking for a way to exit when it hits the output "press the enter key to stop..." I'd certainly appreciate any guidance the wise monks may have, here. Thanks!
