Problem Description: 

   On 4.1.2 FCS software with prestoserve added the following configuration

          galaxy with 128 meg and 1 ross module
          IPI controller with 6 drives
          ......
        * cg6 lego
        * prestoserve
        * cdrom
        * 150Meg tape
        * exabyte

           * Note: must have this exact configuration for these devices
                   don't add or subtract anything otherwise won't be able to 
                   duplicate it.
