11GR2RAC Environment DBCA CREATE DATABASE error ORA-15055 ORA-15001

11GR2RAC Environment DBCA CREATE DATABASE error ORA-15055 ORA-15001

Problem phenomenon:

After the 11GR2 gridinfrastructure and database software installation is complete, execute DBCA Create the database to 30% when the following error, click OK after the prompt to ignore and stop the installation.

Problem Analysis:

from the above question we can see that because the ASM Disk group is not accessible, but to solve the problem you have to go into the ASM to find out, why the newly installed cluster, the problem of building the library.

We then log on to the ASM instance via a grid user to perform the following query, and we find that the disk group is in the Mount state, indicating that there is no obvious problem with the disk group status.

See above information we can basically exclude ASM problem, you might want to consider a permissions issue and try to re-execute root.sh script.

Problem solving:

Re-execute the following script

re-run again DBCA Build a library, troubleshoot problems
