INS-40925 - One or more nodes have interfaces not configured with a subnet that is common across all cluster nodes.

Hi All,

 

I am facing the below error while installing Oracle RAC in Silent Mode.

 

SEVERE: There are no common subnets represented by network interfaces across all cluster nodes.

SEVERE: [FATAL] [INS-40925] One or more nodes have interfaces not configured with a subnet that is common across all cluster nodes.

   CAUSE: Not all nodes have network interfaces that are configured on subnets that are common to all nodes in the cluster.

   ACTION: Ensure all cluster nodes have a public interface defined with the same subnet accessible by all nodes in the cluster.


My /etc/hosts is given below.

127.0.0.1        localhost    localhost.localdomain

#Public

192.168.1.101      rac1        rac1.localdomain

192.168.1.102    rac2        rac2.localdomain

#Private

192.168.2.101    rac1-priv    rac1-priv.localdomain

192.168.2.102    rac2-priv    rac2-priv.localdomain

#Virtual

192.168.1.103      rac1-vip    rac1-vip.localdomain

192.168.1.104    rac2-vip    rac2-vip.localdomain

#SCAN

192.168.1.105    rac-scan    rac-scan.localdomain



Could you please help me to get rid of the error INS-40925....Any Idea...???

    Some of the observations:

     

    Please maintain at least three SCAN IPs.

    Right format of /etc/hosts file

     

     

    127.0.0.1 localhost.localdomain localhost

    [ip_address] [node_name].[domain_name] [node_name]

    Hi,

     

    Many Thanks.

     

    I will definitely do it and let you know my test result.

     

    However, I have only 2 interfaces (i.e. eth0,eth1) for Public & Private connections.

     

    Can anyone tell me if I need to have interface for SCAN also..??

     

    Also, still I am facing the error INS-40925. Can anyone help me regarding this ???

    You don’t require any interface for SCAN and VIP.

    Could you please paste contents of /etc/hosts

    Please post the ifconfig -a output from both nodes.

    Hi Ramesh,

     

     

     

    Please find the result of ifconfig -a from both nodes RAC1 & RAC2.
