环境：Cent0S 6.4 64bit、grid 64bit
自检出现“TCP connectivity of subnet”问题。
【问题】
手工进行grid自检，报出如下错误：
[grid@xzxt1 grid]$ ./runcluvfy.sh stage -pre crsinst -n xzxt1,xzxt2 -fixup -verbose

【解决】
[root@xzxt1 network-scripts]# vi ifcfg-eth0
--去掉GATEWAY=192.168.56.1
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.56.30
NETMASK=255.255.255.0
[root@xzxt1 network-scripts]# vi ifcfg-eth1
--去掉GATEWAY=10.10.10.1
DEVICE=eth1
ONBOOT=yes
BOOTPROTO=static
IPADDR=10.10.10.90
NETMASK=255.255.255.0
重启服务器后，再次自检此问题不再出现。

Floppy Disk(s) fail 或 Floppy Disk(s) fail(80) 或Floppy Disk(s) fail(40)
无法驱动软盘驱动器。
系统提示找不到软驱，首先要看看软驱的电源线和数据线有没有松动或者是接反，最好是是把软驱放到另外一台机子上试一试，如果这些都不行，那么只好再买一个了，好在目前市场中的软驱还不算贵。
Hard disk install failure
硬盘安装失败。这是因为硬盘的电源线或数据线可能未接好或者硬盘跳线设置不当引起的。朋友们可以检查一下硬盘的各根连线是否插好，看看同一根数据线上的两个硬盘的跳线设置是否一样。如果一样，只要将两个硬盘的跳线设置不一样即可(一个设为Master，另一个设为Slave)。
Hard disk(s) diagnosis fail
执行硬盘诊断时发生错误。出现这个问题一般就是硬盘内部本身出现硬件故障了，你可以把硬盘放到另一台机子上试一试，如果问题还是没有解决，只能去修一下了。如果硬盘还在包换期内的话，最好还是赶快去换一块！
Hardware Monitor found an error，enter POWER MANAGEMENT SETUP for details，Press F1 to continue，DEL to enter SETUP
监视功能发现错误，进入POWER MANAGEMENT SETUP查看详细资料，或按F1键继续开机程序，按DEL键进入CMOS设置。现在好一些的主板都具备有硬件的监视功能，用户可以设定主板与CPU的温度监视、电压调整器的电压输出准位监视和对各个风扇转速的监视，当上述监视功能在开机时发觉有异常情况，那么便会出现这段话，这时朋友们可以进入CMOS设置选择POWER MANAGEMENT SETUP，在右面的**Fan Monitor**、**Thermal Monitor**和**Voltage Monitor**查看是哪部分监控发出了异常情况，然后再加以解决。
Keyboard error or no keyboard present
键盘错误或者未接键盘。检查一下键盘与主板接口是否接好，如果键盘已经接好，那么就是主板键盘口坏了，主板如尚在包修期内，朋友们可以找经销商或主板厂家进行解决。
Memory test fail
内存检测失败。重新插拔一下内存条，看看是否能解决，出现这种问题一般是因为混插的内存条互相不兼容而引起的，有条件的话去换一条吧！如果使用的只是一根内存条，那么就一定是内存条本身有问题，还是赶快去换一条的好！
Override enable-Defaults loaded
当前CMOS设定无法启动系统，载入BIOS中的预设值以便启动系统。一般是CMOS内的设定出现错误，朋友们只要进入CMOS设置后选择LOAD SETUP DEFAULTS载入系统原来的设定值然后重新启动即可解决这一问题。
Press ESC to skip memory test
正在进行内存检查，可按ESC键跳过。这是因为在CMOS内没有设定跳过存储器的第二、三、四次测试，开机就会执行四次内存测试，当然你也可以按ESC键结束内存检查，不过每次开机后都要这样做实在太麻烦了，你可以进入CMOS设置后选择BIOS FEATURES SETUP，将其中的Quick Power On Self Test设为Enabled开启，存储后重新启动即可解决。

调主板的BIOSS，好像在integrated peripherals ->onboard LAN boot rom 改为disabled 关上就行了
