sun cluster 实验证明
实验目的：证明两台主机操作系统一样，而update版本不一样，（如一台solaris10u9，另一台solarisu8）也可以做cluster，主机系统：一台solaris10u9 x86，另一台solaris10u8 x86
sun cluster版本：cluster3.2u3
实验环境：vmware workstation 7
共享存储：starwind5.7
实验结果：证明两台主机操作系统一样，而update版本不一样，也是可以做sun cluster。

------------------------------------------------------------------ 这样做有什么意义呢？用可能是没有问题，但是出了问题排除起来就会很麻烦。何必给自己找麻烦呢？ 可以练练手，熟悉下环境也不错。 练练手还可以，恐怕没有人愿意在生产环境上这样做吧！ 恩，鼓励lz，不过生产系统的话原则上是绝对不允许这么折腾 做这个实验也是想和大家一起研究cluster，个人认为这样做是没什么问题的，
毕竟我们以后遇到的问题多种多样， 回复 6# liusu_520
部署生产系统的首要思路就是尽可能的减少潜在的威胁 还有一个，你这个是一两天的试验，生产系统是需要成年累月的运行的，路遥知马力，跑久了，也许这种不兼容的情况就会慢慢显现出来了。
:dizzy: 回复 8# zhmzhouming
还有一种情况就是： 某些配置不被certified,并不是根本就无法work,只是 没做完整的test,出问题厂商不负任何责任。 没意义
