某项目,硬件环境为:
HP DL380G5 两台
HP FC2242SR HBA卡2块,分别装在两台服务器上
HP 光纤交换机一台
HP MSA1000盘阵
RedHat Linux Enterprise Server 4 Update 5
安装完操作系统后,所有驱动都识别正常,盘阵上划分的分区也都能找到。
(借用一下别人显示信息,我的是类似!)

重启服务器后,发现服务器与盘阵的连接丢失。

再重启,又会出现。并不是每次重启服务器都会丢失,机率大概是2/5,丢失以后再重启一下又好了。
上网查了一下,说是有可能是HBA卡的问题。打电话给HP的工程师,他以前也没有遇到过这种情况。不太可能是盘阵的问题,上面的数据都是完好,只是与服务器的连接丢失。
请教一下各位高人,这到底是怎么一回事?小弟是超级新手,第一次接触这类设备。不胜感谢~~~~ |
