I was installing 10.2.0.1 on IBM AIX 5L and while running root.sh from first node (as part of Clusterware installation) got following messages
Now formatting voting device: /dev/voting_disk01 Now formatting voting device: /dev/voting_disk02 Now formatting voting device: /dev/voting_disk03 Format of 3 voting devices complete. Startup will be queued to init within 30 seconds
I waited for quite some time and found that it was stuck. To check what was status of CSS, I did a grep for CSS and found that it was running /etc/init.cssd startcheck css script. This indicated that Oracle was stuck trying to start CSS. Following errors were recorded in /tmp/crsct.7459
Failure in CSS initialization opening OCR.
Metalink notes suggested checking OCR Disk permission , though in my case they had correct permissions i.e ownership as oracle:dba and permission set to 660. To diagnose further, I checked $ORA_CRS_HOME/log to check for errors. All the logfiles related to CRS,CSS and EVMD are stored in $ORA_CRS_HOME/log/<hostname>.

Hostname for the server was rac01 and not chd0196. This was a new server and also directories could not be present earlier as it was a fresh installation. Oracle was picking two hostname which was quite strange. I checked for HACMP filesets and found that they were present

10g RAC does not require Vendor clusterware as Oracle provides it own clusterware called “Oracle Clusterware”.We got these packages un-installed and got both server rebooted. After cleaning up RAC installation, we restarted installation . You can use Metalink Note 239998.1 – 10g RAC: How to Clean Up After a Failed CRS Install for cleanup. On re-running root.sh installation, installation went fine.
