Raj, The problem is not related to tainted kernel. Oracle Kernel Service (OKS) is intentionally proprietary. Oracle has an official explanation for it. Your problem is due to multipath. Does multipath -v2 show everything OK? Does /dev/mapper/ have all the files? You can work with your Oracle DBA on this issue.
