排除CGR 1000的IOS虚拟机监控程序和系统映像恢复故障

简介

本文档介绍运行IOS软件的Cisco 1000系列Connected Grid路由器(CGR 1000)上的虚拟机监控程序和系统映像的恢复步骤。如果虚拟机监控程序或系统映像损坏，此程序可帮助您使CGR 1000路由器重新联机。IOS配置存储在NVRAM中。即使使用另一个思科安全数字(SD)卡，配置也不会删除，除非将运行配置指定存储在另一个位置。

先决条件

• 本地计算机上安装的简单文件传输协议(TFTP)服务器
• 设置TFTP服务器，使其具有虚拟机监控程序和系统映像  

要求

Cisco 建议您了解以下主题：

• 控制台电缆
• CAT5
• 虚拟机监控程序映像、系统映像和捆绑映像

使用的组件

本文档中的信息仅限于在CGR 1120和CGR1240上运行的IOS版本。

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。本文档中使用的所有设备最初均采用原始（默认）配置。如果您使用的是真实网络，请确保您已经了解所有命令的潜在影响。

恢复虚拟机监控程序和系统映像的步骤

下载虚拟机监控程序映像和系统映像

1.在思科上下载任何映像cgr1000-universalk9-bundle.xxx.xxx.xxx.bin。

2.使用7z打开bin文件。

3.双击文件以浏览内容。

4.下载虚拟机监控程序映像(cgr1000-hv.srp.SPA.1.1.1)和系统映像(cgr1000-universalk9-mz.SPA.155-2.T)。

将这三个文件移到TFTP服务器。

• cgr1000-hv.srp.SPA.1.1.1（虚拟机监控程序映像）

• cgr1000-universalk9-mz.SPA.155-2.T（系统映像）

• cgr1000-bundle-universalk9-bundle.SPA.155-2.T.bin（捆绑映像）

IOS的CGR启动顺序

启动顺序为：

开机> BIOS >虚拟机监控程序映像>系统映像> IOS正常操作

如果没有虚拟机监控程序映像，用户会看到：

IOFPGA @ 0xd0000000 version=0x23020900, datecode=0xd091e17 CPLD version 0x13

Reset reason (0.0):   Unknown

BIOS Version: Build # 14 - Wed 04/30/2014

CGR Loader Stage 1 Version: 1.9.16

Autoboot string bootstrap:cgr1000-hv.srp.SPA.1.1.0

Booting image: bootstrap:cgr1000-hv.srp.SPA.1.1.0....

Autoboot failed with error=1



rommon-1>      

如果没有系统映像（IOS映像），用户将看到：

IOFPGA @ 0xd0000000 version=0x23020900, datecode=0xd091e17 CPLD version 0x13

Reset reason (0.0):   Unknown

CGR Loader Stage 2 Version: 1.9.16

Autoboot string flash:/cgr1000-universalk9-mz.SPA.154-3.M1,12;

rommon-2>

恢复步骤 

1.使用putty设置控制台电缆。

2.将CAT5电缆从本地pc网卡连接到CGR ETH 2/2。这是恢复过程中唯一工作的接口。

3.将本地PC NIC设置为与CGR位于同一子网中。 

例如;PC网卡是192.0.2.1子网255.255.255.0。

对于CGR，子网为192.0.2.2，子网为255.255.255.0。

4.在Putty会话中，如果CGR找不到虚拟机监控程序映像，您会看到rommon-1>。

IOFPGA @ 0xd0000000 version=0x23020900, datecode=0xd091e17 CPLD version 0x13
Reset reason (0.0):   Unknown

Booting image: bootstrap:cgr1000-hv.srp.SPA.1.1.0....
Autoboot failed with error=1

5.使用命令set ip设置ETH2/2的IP地址。
    

set ip 192.0.2.2 255.255.255.0
    
Correct - ip addr is 192.0.2.2, mask is 255.255.255.0
Found Intel IOH GBE [2:0.1] at 0xe020, ROM address 0x0000

Address: 192.0.2.2
Netmask: 255.255.255.0
Server: 0.0.0.0
Gateway: 0.0.0.0  

6.使用命令set gw将网关地址设置为本地PC网卡。

set gw 192.0.2.1
Correct gateway addr 192.0.2.1
Address: 192.0.2.2
Netmask: 255.255.255.0
Server: 0.0.0.0
Gateway: 192.0.2.1

7.使用命令boot tftp://从本地tftp服务器启动虚拟机监控程序映像。
    

Boot tftp://192.0.2.1/cgr1000-hv.srp.SPA.1.1.1
Booting: /cgr1000-hv.srp.SPA.1.1.1 console=ttyS0,9600n8nn quiet loader_ver="1.9

RIF heap: 1519616 bytes, SKH heap: 2310144 bytes
RIF: used 7691/16384 bytes of stack    

8.一旦CGR加载虚拟机监控程序映像，并且无法引导系统映像，屏幕应该如此。

12.如果NVRAM仍然完好无损，则运行配置将加载。路由器应仍保存旧配置。

    
    
13.（可选）如果将新SD卡放入CGR，请使用命令partition flash：对新SD卡进行分区。否则，如果当前SD卡确认工作正常，则可跳过此步骤。

format flash: 
Format operation may take a while. Continue? [confirm]
Format operation will destroy all data in "flash:".  Continue? [confirm]

14.在IOS中，gigabitethernet2/2是物理机箱上ETH2/2的端口。使用IP地址192.0.2.2配置gigabitethernet2/2，以便从TFTP服务器复制捆绑映像。

Configure terminal
Interface gigaethernet2/2
Ip address 192.0.2.2 255.255.255.0

    14.使用命令copy tftp：将捆绑包映像从tftp复制到CGR闪存中。flash:

copy tftp: flash:
