Can't start CRS -- giving error about OCR device but ....?? Please help.

Question

I am running CentOS 4.5 64-bit with kernel 2.6.9-55.EL on 2 AMD64 single CPU machines. Installed Oracle Clusterware 10.2.0.1 on both of these (pushing from node1). Then created RAC database using ASM. Everything worked fine & CRS/RAC were up (on both) for sometime. Then I stopped the resources & CRS/RAC. But, after sometime I can't start CRS on any of these! Getting error message (in /tmp/crsctl.pid):
OCR initialization failed accessing OCR device: PROC-26: Error while accessing the physical storage.
But I can see the FireWire drive/RAW partitions using "fdisk -l" and the permission/ownership are correct on the OCR/Voting Disk RAW partitions.
I also don't see any socket opened under /var/tmp/.oracle!
The is no other message in any other error/log file.
What is this & how to solve?
Thanks.

Answer 1

Hi,
Pls refer to the following solution:
1. Please check the rights and owners of the ocr devices
2. Check if the ocrconfig_loc is pointing to the correct ocr in /var/opt/oracle/ocr.loc.
The ocrconfig_loc parameter specifies the location of the Oracle Cluster
Registry (OCR) used by the CSS daemon. The path up to the cdata directory is the Oracle home directory where the CSS daemon is running.
3. Reconfiguring Oracle Cluster Synchronization Services
a. $/u01/app/oracle/product/10G/bin/localconfig delete
Unexpected parameter: css
$
b - I killed init.cssd process
$ps -ef |grep css
root 1559 1 0.1 09:34:53 ?? 0:07.52 /sbin/init.d/init.cssd startcheck
root 16390 16070 0.0 12:33:53 pts/1 0:00.01 grep css
$kill -9 1559
$ps -ef |grep css
root 16407 16070 0.0 12:34:15 pts/1 0:00.01 grep css
c - Set up ORACLE_HOME
$export ORACLE_HOME=/u01/app/oracle/product/10G
$/u01/app/oracle/product/10G/bin/localconfig delete
Enter the following command to reconfigure the CSS daemon to run from this Oracle home:
# $ORACLE_HOME/bin/localconfig reset $ORACLE_HOME
The script stops the Oracle CSS daemon, reconfigures it in the new Oracle home, and then restarts it. When the system boots, the CSS daemon starts automatically from the new Oracle home.
