  1.The /etc/hosts file must contain the following information.

  127.0.0.1       localhost.localdomain   localhost

  # Public

  192.168.2.101   rac1.localdomain        rac1

  192.168.2.102   rac2.localdomain        rac2

  #Private

  192.168.0.101   rac1-priv.localdomain   rac1-priv

  192.168.0.102   rac2-priv.localdomain   rac2-priv

  #Virtual

  192.168.2.111   rac1-vip.localdomain    rac1-vip

  192.168.2.112   rac2-vip.localdomain    rac2-vip

  #NAS

  192.168.2.101   nas1.localdomain        nas1

  2.create shared disks

  First we need to set up some NFS shares. In this case we will do this on the RAC1 node, but you can do the on a NAS or a third server if you have one available. On the RAC1 node create the following directories.

  mkdir /share1

  mkdir /share2Add the following lines to the /etc/exports file.

  /share1                  *(rw,sync,no_wdelay,insecure_locks,no_root_squash)

  /share2                  *(rw,sync,no_wdelay,insecure_locks,no_root_squash)Run the following command to export the NFS shares.

  chkconfig nfs on

  service nfs restartOn both RAC1 and RAC2 create some mount points to mount the NFS shares to.

  mkdir /u01

  mkdir /u02Add the following lines to the "/etc/fstab" file. The mount options are suggestions from Kevin Closson.

  nas1:/share1  /u01  nfs  rw,bg,hard,nointr,tcp,vers=3,timeo=300,rsize=32768,wsize=32768,actimeo=0  0 0

  nas1:/share2  /u02  nfs  rw,bg,hard,nointr,tcp,vers=3,timeo=300,rsize=32768,wsize=32768,actimeo=0  0 0Mount the NFS shares on both servers.

  mount /u01

  mount /u02Create the shared CRS Configuration and Voting Disk files.

  touch /u01/crs_configuration

  touch /u01/voting_diskCreate the directories in which the Oracle software will be installed.

  mkdir -p /u01/crs/oracle/product/10.2.0/crs

  mkdir -p /u01/app/oracle/product/10.2.0/db_1

  mkdir -p /u01/oradata

  chown -R oracle:oinstall /u01 /u02
