解决方法：

重新清除OCR配置信息:

[root@aix224@ /]# dd if=/dev/zero  of=/dev/rrac_ocr  bs=8192  count=2560

建立以下目录：
[root@aix224@ /]#mkdir -p /u01/crs_1/crs/auth
[root@aix224@ /]#chgrp dba /u01/crs_1/crs/auth
[root@aix224@ /]#chmod 755 /u01/crs_1/crs/auth

在两个节点重新运行root.sh（aix223、aix224）：

[root@aix224@ install]#./rootdelete.sh
