Data Mover Configuration

Hi,

I have NS-80 Celerra with 4 Data Mover. Two are in primary and two are Standby datamover.

I want to configure datamover 4 as a primary data mover. Please let me know what parameters we should check and how to configure it as a primary datamover. And how to check its connection with control station? Below are the details:

nas_server -info server_4
id        = 3
name      = server_4
acl       = 0
type      = standby
slot      = 4
member_of =
standbyfor= server_3,server_2
status    :
  defined = enabled
   actual = online, ready

and

server_ifconfig server_4 -all
server_4 :
loop protocol=IP device=loop
         inet=127.0.0.1 netmask=255.0.0.0 broadcast=127.255.255.255
        UP, loopback, mtu=32768, vlan=0, macaddr=0:0:0:0:0:0 netname=localhost
el31 protocol=IP device=mge1
         inet=128.221.253.4 netmask=255.255.255.0 broadcast=128.221.253.255
        UP, ethernet, mtu=1500, vlan=0, macaddr=0:60:16:1e:f:c5 netname=localhost
el30 protocol=IP device=mge0
         inet=128.221.252.4 netmask=255.255.255.0 broadcast=128.221.252.255
