Given the code below, I'd like to perform the join, only if the variable hasn't already been joined.

When I dump the hash that this script creates, the inner hash, "tapes" can have duplicate values. I'll post some output to illustrate. I want only unique (in this case) tape id's to be included.

#!/opt/openv/perl/bin/perl -w

use strict;
use Data::Dumper;
use NBUX;
my %images = bpimagelist();

#print Dumper(\%images);
#exit;

my (%status);

foreach my $key (sort keys %images)
{

        my ($tapes, $img);

        my $client     = $images{$key}->{'client'};
        my $sched_type = $images{$key}->{'schedule_type'};
        my $sched_name = $images{$key}->{'sched_label'};
        my $policy     = $images{$key}->{'policy'};
        my $kb         = $images{$key}->{'kbytes'};

    foreach my $key2 (sort keys %{$images{$key}})
    {

        if ($key2 =~ /copy_\d_frag_\d_id/)
        {
            $img   = $images{$key}{$key2};

            $tapes = (join (' ', $img, $tapes));
            $status{$client}{$policy}{'tapes'} = $tapes;

        }

    }

}

#print Dumper(\%status);
#exit;

Here's some example output that I'm trying to avoid: 
$VAR1 = {
          'bondsrv1' => {
                      'acis_misc_os' => {
                                 'tapes' => 'OK0238 OK0238 '          
+                                                              

                        }               },
        }
