No, -A option is not working.
What I know +A is to append to array, -A is for creating the array clearing off any previous values.
Any other clues..?
thanks for the reply.

I have found the answer after putting little effort and googling. You can append to the original array with below code snippet-

Code:

        set -A ipaddr_arr $(egrep -v '^#|^::|^$' /etc/hosts |awk '{print $1}' | uniq) #hosts ips
        set -A other_arr $(egrep -v '^#|^::|^$' /etc/hosts |awk '{print $1}') 


        if [ "$os" = "solaris" ]
        then
                set -A third_arr $(egrep -v '^#|^::|^$' /etc/hosts |awk '{print $1}')
        else
               #some other statement
        fi
   
       set -A ipaddr_arr ${ipaddr_arr[*]} ${other_arr[*]} ${third_arr[*]}
       #the above code snippet will append all other array values to the first ipaddr_arr
