Oracle recommends that you complete these tasks after installation.

• Configuring IPMI-based Failure Isolation Using Crsctl
  On Oracle Solaris and AIX platforms, where Oracle does not currently support the native IPMI driver, DHCP addressing is not supported and manual configuration is required for IPMI support.
• Tuning Semaphore Parameters
  Refer to the following guidelines if the default semaphore parameter values are too low to accommodate all Oracle processes.
• Creating a Backup of the root.sh Script
  Oracle recommends that you back up the root.sh script after you complete an installation.
• Downloading and Installing the ORAchk Health Check Tool
  Download and install the ORAchk utility to perform proactive heath checks for the Oracle software stack.
• Creating a Fast Recovery Area
  During an Oracle Restart installation, you can create only one disk group. During an Oracle Clusterware installation, you can create multiple disk groups. If you plan to add an Oracle Database for a standalone server or an Oracle RAC database, then you should create the fast recovery area for database files.
• Checking the SCAN Configuration
  The Single Client Access Name (SCAN) is a name that is used to provide service access for clients to the cluster. Because the SCAN is associated with the cluster as a whole, rather than to a particular node, the SCAN makes it possible to add or remove nodes from the cluster without needing to reconfigure clients.
• Setting Resource Limits for Oracle Clusterware and Associated Databases and Applications
  After you have completed Oracle Grid Infrastructure installation, you can set resource limits in the Grid_home/crs/install/s_crsconfig_nodename_env.txt file.
