AIX 5.3 Install Oracle 10g RAC 错误集锦--磁盘I/O 故障
系统环境：
操作系统： AIX 5300-09
集群软件： CRS 10.2.0.1
数据库： Oracle 10.2.0.1
系统架构图
本机采用vg 并发（VG concurrent）作为共享的存储
故障现象：
当在第一个node（aix211）执行root.sh时，被hang住......
查看日志：

出现磁盘的I/O故障！
解决方法：
1、查看PV和VG
[root@aix211 client]#lspv
hdisk0 00040f8aaa29d28e rootvg active
hdisk1 000e1a6ce663b4af racvg concurrent
[root@aix211 client]#lsvg racvg
--查看VG时也 hang 住......看来是共享卷组的磁盘出现了故障，因为是个实验环境，阵列不很稳定，所有重启系统......
2、重启系统后，重新执行root.sh
3、手工执行安装后校验
