since this is your first post, contrary to monks habits, I offer you a working example, but remember: the monastery is not a code writing service! So remember the golden rule: more effort you show more help you, possibly, get in return.

As you are in the need to parse a non standard format ( PS DGMGRL> SHOW CONFIGURATION; always give us as much information you can to help us to help you..;) the task is complex and the solution ugly (be brave!go learn MARPA)

use strict;
use warnings;
use Data::Dumper;

# create top level keys..
my %hash = (
    Configuration => '',
    'Protection Mode' => '',
    Databases    => {},
    Properties => {},
    # Fast-Start Failover => '',  # it's missing in your output..
    'Configuration Status' => ''
);

# track the nasty last line..
my $last_line;
# track the current key with subkeys
my $current_key;

while (<DATA>){
    chomp;
    # skip empty lines
    next if /^$/;
    # remove leaading spaces
    s/^\s+//;
    # split on possible separators
    my @fields = split /\s*\-|:|=\s/,$_;
    # remove unneeded spaces from fields
    $fields[0] =~ s/\s+$//;
    $fields[1] =~ s/\s//g if defined $fields[1];
    
    if ($fields[0] eq 'Configuration Status'){next}
    
    # second field  present? it is a norma key (no subkeys)
    if (defined $fields[1]){
        $fields[1]=~s/'//g;
        # some debug with print...
        print "fields = '$fields[0]' '$fields[1]'\n";
        # are we processing a subkey?
        if ($current_key){
            print "\tdefined current key\n";
            #print "current -> $current_key - $fields[0]\n";
            if (exists $hash{$current_key}){
                print "\texists the key '$current_key'\n";
                $hash{$current_key}{$fields[0]}=$fields[1];
            }
        }
        else {
                # exists the toplevel key? 
                if (exists $hash{$fields[0]}){
                        $hash{$fields[0]} = $fields[1];
                }
                $current_key = undef;
        }
    }
    # else we are processing subkeys...
    else{
        $current_key = $fields[0];            
    }
    $last_line = $fields[0];
    if (eof){
        $hash{'Configuration Status'} = $last_line;
    }
    
}

print Dumper \%hash;
