Configuring the Oracle ASM library driver.
This will configure the on-boot properties of the Oracle ASM library
driver. The following questions will determine whether the driver is
loaded on boot and what permissions it will have. The current values
will be shown in brackets ('[]'). Hitting
answer will keep that current value. Ctrl-C will abort.
Default user to own the driver interface []: oracle
Default group to own the driver interface []: dba
Start Oracle ASM library driver on boot (y/n) [n]: y
Scan for Oracle ASM disks on boot (y/n) [y]:

10. Clone RAC Node1 to RAC Node 2
Copy and Change settings .vmx file of VMWARE in both the nodes.
disk.locking = "FALSE"
diskLib.dataCacheMaxSize = "0"
diskLib.dataCacheMaxReadAheadSize = "0"
diskLib.dataCacheMinReadAheadSize = "0"
diskLib.dataCachePageSize = "0"
scsi1.sharedBus = "virtual"
scsi0:1.deviceType = “disk”
scsi0:1.deviceType = “disk”
scsi0:2.deviceType = “disk”
scsi0:3.deviceType = “disk”
scsi0:4.deviceType = “disk”
scsi0:5.deviceType = “disk”
Change Ip address, Host name in /etc/sysconfig/network and enable both Ethernet adaptors.
11. Setup Oracle User equivalency – This is needed for clusterware daemons to communicate with each other without password prompt
[oracle@node1 ~]$ chmod 755 .ssh
[oracle@node1 ~]$ cd /home/oracle/.ssh/
[oracle@node1 .ssh]$ ls
[oracle@node1 .ssh]$ chmod 755 /home/oracle/.ssh/
[oracle@node1 .ssh]$
Change the X11Forwarding to no in order to avoid a WARNING: no xauth data; using fake authtication data for x11 forwarding
