14 Troubleshooting
The Oracle Clusterware installation procedure fails.
The Oracle Clusterware installation fails because the EMC
®
PowerPath
®
device names are not uniform across the nodes.
Before you install Oracle Clusterware, re-start PowerPath and ensure
that the PowerPath device names are uniform across the nodes.
CRS fails to start when you reboot the nodes, or after entering
/etc/init.d/init.crs start.
CRS fails to start when the Cluster Ready Services CSS daemon is unable
to write to the quorum disk.
Attempt to start the service again by rebooting the node or typing:
root.sh from /crs/oracle/product/11.1.0/crs/
Verify that each node has access to the quorum disk and the user root
can write to the disk.
Check the last line in the file $ORA_CRS_HOME/css/log/ocssd.log.
If you see:
clssnmvWriteBlocks: Failed to flush writes
to (votingdisk),
verify the following:
•The /etc/hosts file on each node contains the correct IP addresses
for all node hostnames, including the virtual IP addresses.
• You can ping the public and private hostnames.
• The Oracle Cluster Registry(OCR) file and Voting disk is writable.
When you run root.sh, CRS fails to start.
NOTE: Ensure that you have all the public and private node names defined
and you can ping the node names.
Attempt to start the service again by rebooting the node or by running root.sh
from /crs/oracle/product/11.1.0/crs/ after correcting the networking issues.
