磁带机恢复AIX操作系统方案

系统不能启动后必须由终端进行启动控制，一般IBM服务器都有串口终端，但是必须有IBM的串口线才能登陆到系统，以下是IBM串口线的做法：

（我们这里讨论的是DB9 也就是9 针的串口，因为这是我们最常用到的规格）， 我们知道，DB9 串口线分为两种：标准的RS232 接法和交叉RS232 接法，一般来说我们需要用到串口时很可能就是需要登陆到小机上进行操作，比如系统设置和安装AIX 等待，那我们用到的就是交叉的RS232 接法了（其实我们在发的工具箱里面能看到有根串口线，但是似乎是按照标准接法做的，各位兄弟可以Check 一下是不是这样^_^），我们来看看DB9 头的针脚定义： 9 针串口功能一览表 针脚 功能

1 载波检测 （DCD） 2 接收数据 （RXD） 3 发送数据（TXD）

4 数据终端准备好 （DTR） 5 信号地 （GND）

6 数据准备好 （DSR） 7 发送请求 （RTS） 8 发送清除 （CTS） 9 振铃指示 （RI）

知道了其功能做起来就很简单了，我们在制作时将发送段和接收段的对调，也就 是发送脚接到对方的接收段即可，也就是： 2 —— 3 3 —— 2 4 —— 6 1 5 —— 5 1 6 —— 4 7 —— 8 8 —— 7 9 空脚

这里有一点要特别注意的是，1 和6 脚一定要短接后和对方的4 脚相连，不然 有可能造成无法通讯的故障（这应该是IBM 做的一个定义，因为在其他品牌设 备上并不需要这样的接法），我在做到这里的时候做过测试，发现确实无法实现 通讯。

附颜色与引脚的关系（不知道此关系有没有通用性）：

1 黑，2 棕，3 红，4 橙，5 黄，6 绿，7 蓝，8 紫，9 白。 至此， 我们的超级串口线就做好了

2. 配置终端

将终端线连入到IBM服务器COM1 口。 串口配置如下

Baud rate: 9600 Data bits: 8 Parity: None Stop bits:1

DTR/DSR、RTS/CTS、XON/XOFF都不用选上

3. 恢复操作

1. 将服务器通电但不开机：

2. 通过终端连入到主机中可以看到以下界面：
