Your code in sub locallb_get_member_v2 { constructs a weird data structure and contains stuff that makes it hard to believe this is meant as such:

 $members{ $status->{'address'} = $member->{'port'}};

Are you sure that this code is intended as such? Did you maybe mean the following? Note the placement of curly braces

  $members{ $status->{'address'}} = $member->{'port'};

Also, are you using the strict pragma? I can't find where you declare $status, but you use it in the next line:

  $members{ $status}->{'enabled'} = $ENABLED_STATUS_MAP->{ $status->{'
+enabled_status'} }

If your problem is that you are unclear about where parentheses go when assigning things to hashes, I recommend using intermediate variables to store the elements and use sequences of very simple assigments. What key in %members did you want to assign to? $members{ $status } or $members{ $status->{'enabled'} }?

I recommend restructuring all your hash assignments like the following structure:

  # Restructure the following line
  # $members{ $status}->{'enabled'} = $ENABLED_STATUS_MAP->{ $status->
+{'enabled_status'} } 
  # ... into lines that end up $members{ $key }= $value;
  my $key= $status;
  my $value= $ENABLED_STATUS_MAP->{ $status->{'enabled_status'} };
  warn "Assigning '$key'='$value' in results";
  $members{ $key }= $value;

If you read your code like that, it seems highly unlikely to me that you really meant that. Maybe you meant the following?

  # $members{ 'enabled' }= $ENABLED_STATUS_MAP->{ $status->{'enabled_s
+tatus'} } 
  # ... into lines that end up $members{ $key }= $value;
  my $key= 'enabled';
  my $value= $ENABLED_STATUS_MAP->{ $status->{'enabled_status'} };
  warn "Assigning '$key'='$value' in results";
  $members{ $key }= $value;
