Verify CI device

Verify cluster Interconnect 
Check for active Nodes
[root@grac41 ~]# olsnodes  -n -i -s -t
grac41    1    192.168.1.218    Active    Unpinned
grac42    2    192.168.1.199    Active    Unpinned

Locate cluster interconnect device 
[root@grac41 Desktop]# oifcfg getif
eth1  192.168.1.0  global  public
eth3  192.168.3.64  global  cluster_interconnect
--> eth3 is out CI device 

Verify status of our Network devices 
On Node grac41
[root@grac41 Desktop]# ifconfig eth3
eth3      Link encap:Ethernet  HWaddr 08:00:27:92:43:5B  
          inet addr:192.168.3.101  Bcast:192.168.3.127  Mask:255.255.255.192
          inet6 addr: fe80::a00:27ff:fe92:435b/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1   
On Node grac42 
[root@grac41 Desktop]# ssh grac42 ifconfig eth3
eth3      Link encap:Ethernet  HWaddr 08:00:27:AB:00:74  
          inet addr:192.168.3.102  Bcast:192.168.3.127  Mask:255.255.255.192
          inet6 addr: fe80::a00:27ff:feab:74/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

--> Verify that interface has same name ( eth3 ) , MTU size,  Bcast, Net Mask and  
    status is  UP BROADCAST RUNNING MULTICAST
