On each destination node, perform the following preinstallation steps:
Specify the kernel parameters
Configure block devices for Oracle Clusterware devices
Ensure that you have set the block device permissions correctly
Use short, nondomain-qualified names for all of the names in the /etc/hosts file
Test whether the interconnect interfaces are reachable using the ping command
Verify that the VIP addresses are not active at the start of the cloning process by using the ping command (the ping command of the VIP address must fail)
On AIX systems, and on Solaris x86-64-bit systems running vendor clusterware, if you add a node to the cluster, then you must run the rootpre.sh script (located at the mount point it you install Oracle Clusterware from a DVD or in the directory where you unzip the tar file if you download the software) on the node before you add the node to the cluster
Run CVU to verify your hardware and operating system environment
Refer to your platform-specific Oracle Clusterware installation guide for the complete preinstallation checklist.
Note:
Unlike traditional methods of installation, the cloning process does not validate your input during the preparation phase. (By comparison, during the traditional method of installation using OUI, various checks occur during the interview phase.) Thus, if you make errors during the hardware setup or in the preparation phase, then the cloned installation fails.
