Solução de problemas de flash de inicialização e recuperação de imagem do sistema para CGOS CGR 1000

Introduction

  

Este documento descreve as etapas de solução de problemas para recuperar o flash de inicialização e a imagem do sistema no CGR 1000.

Informações de Apoio

O CGR1000 usa a memória do cartão Cisco Secure Digital (SD) para armazenar imagens de início de sessão, imagens do sistema, configurações, etc.  Em raras ocasiões, o cartão SD é corrompido. Como resultado, a imagem de início e/ou a imagem do sistema fica corrompida. Isso impede que o CGR seja inicializado. A sequência para a inicialização é descrita na figura fornecida. O procedimento descrito neste artigo é restaurar o CGR de um estado de memória de cartão SD corrompido.

Prerequisites

1. Servidor Trivial File Transfer Protocol (TFTP) instalado no PC local

2. Configure o servidor TFTP para ter a imagem de início rápido e a imagem do sistema

Requirements

A Cisco recomenda que você tenha conhecimento destes tópicos:

1. Cabo do console

2. CAT5

3. A imagem de início e as imagens do sistema

Componentes Utilizados

Este documento está restrito apenas à versão CGOS em execução no CGR 1120 e no CGR1240.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Etapas de recuperação

1. Configure o cabo do console usando putty.

2. Conecte o cabo CAT5 da placa de rede do pc local ao CGR ETH 2/2 . Essa é a única interface que funciona no momento do processo de recuperação.

3. Configure a placa de rede do pc local para estar na mesma sub-rede que o CGR. 

Por exemplo; a placa de rede do PC é a sub-rede 192.0.2.1 255.255.255.0.

Para o CGR, a sub-rede 255.255.255.255.0 será 192.0.2.2.

4. Na sessão de Putty, você verá:

"loader>"

              CGR Loader Version 1.00.01


 loader>

5. Configure o endereço IP de ETH2/2 com o comando "set ip".

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

Netmask: 255.255.255.0
Server: 0.0.0.0
Gateway: 0.0.0.0


loader>

6. Configure o endereço do gateway para ser a placa de rede do PC local com o comando "set gw".

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. Inicialize a imagem do kickstart a partir do servidor tftp local com o comando "boot tftp://".  

loader> boot tftp://192.0.2.1/cgr1000-uk9-kickstart.5.2.1.CG4.3.SPA.bin      
Address: 192.0.2.2

9. Formate o cartão SD corrompido com o comando "format bootflash:".

This command is going to erase the contents of your bootflash:.

Do you want to continue? (y/n)  [n] y


Formatting bootflash:

Formatting completed

10. Execute o init system (etapa de opção: esse comando formata o cartão SD e apaga tudo).

Router(boot)# init system
This command is going to erase your startup-config, licenses as well as the contents of your bootflash:.

Do you want to continue? (y/n)  [n] yInitializing the system
mount: /dev/mmcblk0p4 already mounted or /bootflash busy
mount: according to mtab, /dev/mmcblk0p4 is already mounted on /bootflash

cp: omitting directory `/bootflash/'
Partitioning failed

11. Configure a interface de gerenciamento (isso é necessário para copiar o kickstart e a imagem do sistema no flash de inicialização).

Router(boot)# configure terminal
Router(boot)(config)# interface mgmt0
Router(boot)(config-if)#ip address 192.0.2.2 255.255.255.0
Router(boot)(config-if)#no shut

12. Copie a imagem do sistema e do início no flash de inicialização.

Router(boot)# copy tftp://192.0.2.1/cgr1000-uk9-kickstart.5.2.1.CG4.3.SPA.bin bootflash:
Trying to connect to tftp server......
Connection to server Established. Copying Started.....

Router(boot)# copy tftp://192.0.2.1/cgr1000-uk9.5.2.1.CG4.3.SPA.bin bootflash:

Connection to server Established. Copying Started.....

TFTP get operation was successful
Copy complete, now saving to disk (please wait)...

13. Verifique se a imagem do sistema e do início está no CGR com "dir".

Router(boot)#dir

14. Inicialize a imagem do sistema com o comando "load bootflash".

Router(boot)# load bootflash:cgr1000-uk9.5.2.1.CG4.3.SPA.bin

15. Quando o CGR for inicializado na imagem do sistema, você precisará instalar o kickstart e a imagem do sistema com "install all bootflash:<kickstart-image> system bootflash:<system image>.

cgr1120# install all kickstart bootflash:cgr1000-uk9-kickstart.5.2.1.CG4.3.SPA.bin system bootflash:cgr1000-uk9.5.2.1.CG4.3.SPA.bin
