How do I determine for a certain key I have certain values in the anonymous array? I was to determine if vhost5 contains l02duapofqa and not something else. Or I want to determine is l02duapofqa is owned by vhost5. Data structure is: 

__DATA__
'vhost5' => [
                'l02duapofqa_r1',
                'l02duapofqa1_d1'
            ]


__CODE__

use strict;
use warnings;
open (LSMAP, "-|", "/usr/ios/cli/ioscli lsmap -all") or die $!;
        while  ($lsm = (<LSMAP>)) {
            if ($lsm =~ /^Backing device\s+(\w+)\.\w+$/i) {
                push @{$vhosts{$host}}, $1;
                next;
            }
            my ($p1, $p2, $p3) = split /\s+/, $lsm;
            $host = $p1 if defined $p3 && $p1 =~ /^(vhost.*)$/i;
        }

$a="vhost11";
$b="l02duapofqa2_d1";
#use Data::Dumper; print Dumper \%vhosts;
OUTER:
for my $vhname (sort keys %vhosts) {
    for my $luname ( @{$vhosts{$a}} ) {
        grep /$b.*/, @{$vhosts{$luname}};
        print "\n$vhname -> $luname\n";
        if ( !grep /$a.*/, @{$vhosts{$b}} ) {
            print "\nincorrect vhost\n";
            die;
        }
        else {
            print @{$vhosts{$a}},"\ncorrect\n";
            last OUTER;
        }
    }
}
