Gurus,
        Good Morning. We had two node RAC instance on 11g Rel 2 (11.2.0.2)

        Last Saturday we had some maintenance which involved the restart 
of the Instance including ASM instance. There is no Change in DB or ASM 
Side. 

        When we tried to stop the ASM instance it failed and later it 
aborted by the cluster service stop command internally. 

        When we bring the Node 1 again ASM instance is not started and 
keep getting terminated. When we closely check the alert log of both ASM 
Nodes found the private IP address is not matching. It was good until the 
restart . Since IP are not matching the Disk Groups are not getting 
mounted and it made us to restart the server then both ASM alert log 
showed as private interconnect IP as 169.254.x.x and everything is working 
fine. 

        What is my questions to gurus/experts are 

                1. What might caused to change private interconnect IP 
segment even though we have specified the private interconnect segment as 
192.168.x.x?

                2. Do we have any problem since both nodes are running on 
private Interconnect IP segment 169.254.x.x?
 

Node 1: ASM Alert Log
Private Interface 'eth1' configured from GPnP for use as a private 
interconnect.
  [name='eth1', type=1, ip=192.168.X.X,  net=192.168.X.0/24, 
mask=255.255.255.0, use=cluster_interconnect/6]

Node 2: ASM Alert Log
Private Interface 'eth1:1' configured from GPnP for use as a private 
interconnect.
  [name='eth1:1', type=1, ip=169.254.X.X, net=169.254.X.X/16, 
mask=255.255.0.0, use=haip:cluster_interconnect/62]

Alert Log in Databases - Occurred multiple times

CRS-2302:Cannot get GPnP profile. Error CLSGPNP_NO_DAEMON (GPNPD daemon is 
not running)

CRS-5019:All OCR locations are on ASM disk groups [DG_DATA01], and none of 
these disk groups are mounted.
