简介
本文档介绍如何从引导加载程序提示和引导模式恢复多层数据中心交换机(MDS)。
为了正常工作，MDS交换机需要有效的非损坏启动和系统映像才能完全启动。无效、损坏或缺失Kickstart映像会阻止交换机启动并在启动加载程序提示符处停止。具有有效Kickstart映像，但系统映像无效或缺失的交换机将进入引导模式。
先决条件
要求
思科建议您了解以下主题：
- MDS9000 CLI配置命令
- 如何设置到MDS交换机的控制台连接。
- 如何通过管理端口将MDS交换机设置或连接到网络。
- 熟悉TFTP。
使用的组件
本文档中的信息基于软件要求版本6.2(9)及更高版本。
本文档使用的是支持12到48个线速16 Gbps光纤通道端口的MDS9148S交换机名称tempest。
本文档中的信息都是基于特定实验室环境中的设备编写的。如果您的网络处于活动状态，请确保您了解所有命令的潜在影响。
交换机启动顺序
BIOS > Loader > Kickstart Image > System Image
- 基本输入输出系统(BIOS)加载加载程序。
- 加载器将启动映像加载到RAM中并启动启动映像。
- 启动映像加载并启动系统映像。
- 系统映像读取启动配置文件。
交换机提示
| 阶段 |
提示 |
描述 |
| BIOS |
不可启动 |
BIOS开始加电自检和内存测试。 |
| 加载程序 |
loader> |
启动加载器解压缩加载的软件以启动启动映像。 Ctrl + C（Control Key和C Key）进入引导加载程序提示符。 |
| 启动 |
switch(boot)# |
启动加载器阶段结束时，按Ctrl + ]（控制键和右括号键）进入启动模式。 |
| system |
登录: |
系统映像加载启动配置文件，并将交换机返回到登录提示符。 |
恢复程序
从交换机控制台会话。
loader>
步骤1.下载交换机的Kickstart和System映像，并将其放入TFTP服务器目录中。
在本示例中，TFTP服务器的IP地址为64.104.204.100。
步骤2.配置交换机管理IP地址及其默认网关。
- 配置交换机的接口管理IP地址。
loader> net —ip=10.66.78.80
- 配置交换机的接口管理子网掩码
loader> net —nm=255.255.255.128
- 配置交换机的默认网关IP地址。
loader> net —gw=10.66.78.4
在本例中：
- 交换机接口mgmt0 IP地址为10.66.78.80 255.255.255.128
- 交换机默认网关IP地址为10.66.78.4
步骤3.测试TFTP服务器和交换机之间的IP连接。
从TFTP服务器ping交换机管理IP地址。
C:\Users\mpandika> ping 10.66.78.80 Pinging 10.66.78.80 with 32 bytes of data: Reply from 10.66.78.80: bytes=32 time=2ms TTL=60 Reply from 10.66.78.80: bytes=32 time=3ms TTL=60 Reply from 10.66.78.80: bytes=32 time=3ms TTL=60 Reply from 10.66.78.80: bytes=32 time=3ms TTL=60 Ping statistics for 10.66.78.80: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 2ms, Maximum = 3ms, Average = 2ms C:\Users\mpandika>
步骤4.启动位于TFTP服务器目录中的Kickstart映像，使交换机进入启动模式。
