Thank your both for the code.... i took agama's code and tried to add some of my own to grab the options (the -p or -b) but i'm surely missing something.

Code:
NF < 2 { host = $1; next; } 

NR == FNR {             
        prd_option[ prod[$8] = host ] = $9;
        next;
}

{                       
        bck_option[ back[$8] = host ] = $9;
        next;
}

    END {
        for( x in prod )
            printf( "%s, %s, %s, %s, %s\n", x, prod[x], prd_option[x], back[x] == "" ? "NO BACKUP HOST" : back[x], bck_option[x] );
}

In first loop: since x in prod = instance_name1, my toughts where that prd_option[instance_name1] would equal -p
In last printf: again since i have two arrays (one prod, one backup) i would get something in prd_option[instance_name1] that would equal my -p or -b or nothing if its empty.

I'm surely missing something OR i got this all wrong.... Thanks.
