INS-20802 Oracle Cluster Verification Utility failed

I was trying to install Oracle 12cR1 RAC on a two-nodes AIX 7.2 cluster. Encountered this error when Installer performing Cluster Verification in the step 18/19.

oracle cluster verification failed

With this error occured, RAC status seemed normal though:

bash-3.00# ./crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online

Any ideas about how to fix this? is it okay to just ignore it?

Solution

  • I'm pretty sure this is an Oracle bug related to the cvu_prereq.xml file. RE MOS Doc ID 2169858.1 simply verify that all your pre-reqs are valid then run the installer with the ignoreSysPrereqs flag. 

    /runInstaller -ignoreSysPrereqs
