CRSD,CSSD and EVMD daemons are not starting after system eboot

Environment
--------------

OS - RHEL 5.7
Cluster  version - 10.2.0.5

Steps to check
-------------

1. The prerequisite check with the 'init.cssd startcheck' execution

The clusterware scripts further run a check script to know whether the clusterware is startable before launching the clusterware processes, that is, to check whether basic prerequisites are met and permit the clusterware to start :

[root@coltdb03 init.d]# /etc/init.d/init.cssd startcheck
       If the command hangs, go to /tmp/crsctl.XXXX file to check the error

[root@coltdb03 tmp]# cat crsctl.4315
OCR initialization failed accessing OCR device: PROC-26: Error while accessing the physical storage Operating System error [Permission denied] [13]

In this case the permission for OCR files where missing. so after grating the required permission and privileges, execute the init.cssd startcheck command once again.This time it should return to command prompt immediately
