You can keep the displayDevNum in a variable global to the loop. Like this:
#!/usr/bin/perl
use strict;
use warnings;
my $last_dev_num;
while (my $line = <>)
{
chomp($line);
if (my ($dev_num) = $line =~ /\AdisplayDevNum=(.*)\z/)
{
$last_dev_num = $dev_num;
}
elsif (my ($wwn) = $line =~ /\AWWN=(.*)\z/)
{
print "$last_dev_num $wwn\n";
}
}
