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.
