TROUBLESHOOT RAC CRS STARTUP ISSUES
In oracle rac, it is often tedious to diagnose and troubleshoot crs startup issues during a production downtime or any activity
We have to react quickly to understand the cause of issue and try to narrow down issue to resolve the error.
[root@exdbadm01 oracle]# crsctl start cluster -all
CRS-4639: Could not contact Oracle High Availability Services
CRS-4000: Command Start failed, or completed with errors.Check if crs daemon is up and running on your system
[root@exdbadm01 oracle]# ps -ef|grep crsd.bin|grep -v 'grep'
root 5209 1 0 20:20 ? 00:00:03 /u01/app/11.2.0/bin/crsd.bin reboot
Check for errors in crsd log and try to narrow down the cause of issue
[root@exdbadm01 oracle]# grep 'error' /u01/app/11.2.0/log/exdbadm01/crsd/crsd.log|tail

Use clusterware commands using crsctl utility
[root@exdbadm01 oracle]# . oraenv
ORACLE_SID = [exdbx] ? +ASM1
The Oracle base remains unchanged with value /u01/app/oracle
[root@exdbadm01 oracle]# crsctl check cluster
CRS-4535: Cannot communicate with Cluster Ready Services
CRS-4529: Cluster Synchronization Services is online
CRS-4534: Cannot communicate with Event Manager
Verify the inittab.crs script and try to find if there are any modifications
[root@exdbadm01 oracle]# grep '/etc/init.d/init.ohasd' /etc/inittab.crs
h1:35:respawn:/etc/init.d/init.ohasd run >/dev/null 2>&1 </dev/null
Check the init.ohasd script for any missing lines
[root@exdbadm01 oracle]# cat /etc/init.d/init.ohasdCheck the runlevels of the init bootloader
[root@exdbadm01 ~]# cat /etc/inittab|grep 'id'
