    INS-40931: Unfounded subnet complaint?

    90d66f69-2b23-4816-9e5a-e4554d628ec0

      Hi,

       

      I have been asked to build out servers intended for an 11.2.0.3 RAC installation. I have build two VMs running OL-Linux 6.4.

       

      Three interfaces on each node;

      eth0=host01/02

      eth1=host01-data/02-data

      eth2=host01-clus/02-clus

       

      host02

      DEVICE=eth0

      NETMASK=255.255.255.0

      IPADDR=167.237.122.28

      DEVICE=eth1

      IPADDR=167.237.124.15

      NETMASK=255.255.255.0

      DEVICE=eth2

      IPADDR=167.237.123.132

      NETMASK=255.255.255.224

       

      host02

      DEVICE=eth0
      NETMASK=255.255.255.0
      IPADDR=167.237.122.29
      DEVICE=eth1
      IPADDR=167.237.124.16
      NETMASK=255.255.255.0
      DEVICE=eth2
      IPADDR=167.237.123.133
      NETMASK=255.255.255.224


      I had a situation with a INS-40724 error, but fixed that by moving the SCAN IPs to the same subnet as ETH0;

      SCAN IPs

      167.237.122.47

      167.237.122.48

      167.237.122.49

       

      Now my DBA is now hung up on a similar installation error; INS-40931. Error text:

      [INS-40931] THe following nodes have interfaces that are configureded on a subnet that is different from the SCAN subnet:

      [owbsljddba01-vip.domain.com, owbsljddba01-vip.domain.com].

      (NOTE: The *-vip SCAN IPs are not assigned to an interface, but have addresses that resolve in DNS.)

       

      The confusing part is that the subnets actually do match;

       

      From 01

      [oracle@owbsljddba01:]$ host owbsljddba.domain.com

      owbsljddba.domain.com has address 167.237.122.48

      owbsljddba.domain.com has address 167.237.122.47

      [oracle@owbsljddba01:]$ host owbsljddba01.domain.com

      owbsljddba01.domain.com has address 167.237.122.28

      [oracle@owbsljddba01:]$ host owbsljddba02.domain.com

      owbsljddba02.domain.com has address 167.237.122.29

      [oracle@owbsljddba01:]$ host owbsljddba01-vip.domain.com

      owbsljddba01-vip.domain.com has address 167.237.122.31

      [oracle@owbsljddba01:]$ host owbsljddba02-vip.domain.com

      owbsljddba02-vip.domain.com has address 167.237.122.32

       

      From 02

      [oracle@owbsljddba02:]$ host owbsljddba.domain.com

      owbsljddba.domain.com has address 167.237.122.49

      owbsljddba.domain.com has address 167.237.122.47

      owbsljddba.domain.com has address 167.237.122.48

      [oracle@owbsljddba02:]$ host owbsljddba01.domain.com

      owbsljddba01.domain.com has address 167.237.122.28

      [oracle@owbsljddba02:]$ host owbsljddba02.domain.com

      owbsljddba02.domain.com has address 167.237.122.29

      [oracle@owbsljddba02:]$ host owbsljddba01-vip.domain.com

      owbsljddba01-vip.domain.com has address 167.237.122.31

      [oracle@owbsljddba02:]$ host owbsljddba02-vip.domain.com

      owbsljddba02-vip.domain.com has address 167.237.122.32

       

      It sure seems like this install wants *everything* on the same subnet, but this almost implies that we need to have all interfaces matched.

      We have another RAC setup of the same version that is set up on a physical server with interfaces on different subnets.

      Can I get some advice on what I should be doing to get around this?

       

      Thanks, R
