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......

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，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
