在AIX6.1下安装ORACLE11.2.0.4 RAC的时候，在节点2执行root.sh报错如下：
[root@oratest02:/oracle/]#sh /oracle/app/11.2.0/grid_1/root.sh

Purpose

Details

Case 1: CRS-4046 happens when running root.sh

This document is being delivered to you via Oracle Support's Rapid Visibility (RaV) process and therefore has not been subject to an independent technical review.

PURPOSE

This note lists known issues, workaround and solutions for the following Grid Infrastructure errors:

CRS-4046: Invalid Oracle Clusterware configuration.
CRS-4000: Command Create failed, or completed with errors.

DETAILS

Case 1: CRS-4046 happens when running root.sh

It's likely that the leftovers from previous install caused the root.sh to fail.

Solution:

If setting up Grid Infrastructure cluster, on the node where the error was reported, as root, execute the following:

# /crs/install/rootcrs.pl -deconfig -force -verbose

If setting up Grid Infrastructure Standalone (Oracle Restart), as root, execute the following:

# /crs/install/roothas.pl -deconfig -force -verbose

If the output is similar to the following:

..
CRS-4046: Invalid Oracle Clusterware configuration.
CRS-4000: Command Stop failed, or completed with errors.

ACFS-9313: No ADVM/ACFS installation detected.
Failure in execution (rc=-1, 256, No such file or directory) for command /etc/init.d/ohasd deinstall
error: package cvuqdisk is not installed
Successfully deconfigured Oracle clusterware stack on this node

Either reboot the node or execute the following to stop any processes that's still running from GRID_HOME:

										# ps -ef| grep 

i.e.: # ps -ef| grep "/ocw/grid"

If there's still processes, kill them with "kill -9" command

Once the above reboot or stop is done, as root, execute root.sh from GRID_HOME:

										# /root.sh
									

可如下解决：
