    585864
      I am facing problem for installing RAC on Redhat 4.7 /etc/host file entries is as:

      127.0.0.1 RAC1 localhost.localdomain localhost
      192.168.1.231 rac1.sadtex.com rac1
      192.168.1.234 rac2.sadtex.com rac2

      192.168.1.236 rac2-vip.sadtex.com rac2-vip

      When i run ./runcluvfy.sh stage -pre crsinst -n RAC1 is howing as:

              Hey..
              Can you use other sub net else for interconnect?
              You try to use internetconnect + vip + ip address ... on the same subnet...
              IP + VIP should be on the same subnet,
              But internetconnect use another .... (different)

              Example:

              127.0.0.1 localhost.localdomain localhost
              192.168.1.231 rac1.sadtex.com rac1
              192.168.1.234 rac2.sadtex.com rac2

              +#Private Network/interconnect (used for the cluster)+
              +192.168.10.232 rac1-priv.sadtex.com rac1-priv+
              +192.168.10.235 rac2-priv.sadtex.com rac2-priv+

              # VIP/Used to reroute the client request
              192.168.1.233 rac1-vip.sadtex.com rac1-vip
              192.168.1.236 rac2-vip.sadtex.com rac2-vip

              Or

              127.0.0.1 localhost.localdomain localhost
              192.168.1.231 rac1.sadtex.com rac1
              192.168.1.234 rac2.sadtex.com rac2

              +#Private Network/interconnect (used for the cluster)+
              +10.1.1.1 rac1-priv.sadtex.com rac1-priv+
              +10.1.1.2 rac2-priv.sadtex.com rac2-priv+

              # VIP/Used to reroute the client request
              192.168.1.233 rac1-vip.sadtex.com rac1-vip
              192.168.1.236 rac2-vip.sadtex.com rac2-vip

              **** and change ip address on Interface as well


              Good Luck.

                  Ignore the VIP errors, Oracle expects the IP to be 172.xxxx, or something like that. You could always go back and edit the network configuration via VIPCA if you have issues. Oracle Clusterware only needs an un-assigned IP which it will manage as a VIP.
