Add or edit the following line in the /etc/pam.d/login file, if it does not already exist:
session required pam_limits.so

Add the following lines to /etc/profile:

if [ $USER = "oracle" ]; then

Imp metalink notes to look at before installation: 452780.1.

Setup user equivalence between the rac nodes.
Check that oracle is able to ssh between the rac servers without having to type the password.
Setup up location of OCR & Voting disk files. For test purposes I used the same mount point with different folders for each e.g.
/DB01/ocr
/DB01/voting_disk

Now run the cluster verify utility to do a pre-check before the cluster installation.
[oracle@oradbdev01 clusterware]$ ./runcluvfy.sh stage -pre crsinst -n oradbdev01,oradbdev02 -verbose

System requirement failed for ‘crs’

Pre-check for cluster services setup was unsuccessful on all the nodes.

The check has failed for me for checking if oracle users primary group is “oinstall”. I am using dba as the groups. Hence I am omitting this error.
