Solução de problemas do hipervisor IOS e recuperação de imagem do sistema para CGR 1000
Contents
Introduction
Este documento descreve as etapas de recuperação para o hipervisor e a imagem do sistema no Cisco 1000 Series Connected Grid Router (CGR 1000) que executa o software IOS. Se a imagem do hipervisor ou do sistema estiver corrompida, esse procedimento poderá ajudá-lo a colocar o roteador CGR 1000 novamente on-line. A configuração do IOS é armazenada na NVRAM. Mesmo que outro cartão Cisco Secure Digital (SD) seja usado, a configuração não será excluída, a menos que a configuração atual tenha sido especificada para ser armazenada em outro local.
Prerequisites
- Servidor Trivial File Transfer Protocol (TFTP) instalado no computador local
- Configurar o servidor TFTP para ter o hipervisor e a imagem do sistema
Requirements
A Cisco recomenda que você tenha conhecimento destes tópicos:
- Cabo do console
- CAT5
- Imagem do hipervisor, imagem do sistema e imagem do pacote
Componentes Utilizados
As informações neste documento estão restritas somente à versão do IOS 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 para recuperar o hipervisor e a imagem do sistema
Download de imagens do hipervisor e imagens do sistema
1. No Cisco, faça download das imagens cgr1000-universalk9-bundle.xxx.xxx.xxx.bin.
2. Use 7z para abrir o arquivo bin.
3. Clique duas vezes no arquivo para navegar pelo conteúdo.
4. Baixe a imagem do hipervisor (cgr1000-hv.srp.SPA.1.1.1) e a imagem do sistema (cgr1000-universalk9-mz.SPA.155-2.T).
Mova esses três arquivos para o servidor TFTP.
- cgr1000-hv.srp.SPA.1.1.1 (imagem do hipervisor)
- cgr1000-universalk9-mz.SPA.155-2.T (imagem do sistema)
- cgr1000-bundle-universalk9-bundle.SPA.155-2.T.bin (imagem de pacote)
Sequência de inicialização de CGR para IOS
A ordem da sequência de inicialização é:
Ligar > BIOS > Imagem do hipervisor > Imagem do sistema > Operação normal para IOS
Se não houver imagem do hipervisor, o usuário verá o seguinte:
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>
Se não houver imagem do sistema (imagem do IOS), o usuário verá o seguinte:
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>
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 durante o processo de recuperação.
3. Configure a placa de rede local do PC para estar na mesma sub-rede que o CGR.
Por exemplo; A placa de rede do PC é a sub-rede 255.255.255.0 192.0.2.1.
Para o CGR, a sub-rede 255.255.255.255.0 será 192.0.2.2.
4. Na sessão Putty, você verá rommon-1> se o CGR não consegue encontrar a imagem do hipervisor.
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>
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

Address: 192.0.2.2
Netmask: 255.255.255.0
Server: 0.0.0.0
Gateway: 0.0.0.0
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 hipervisor a partir do servidor tftp local com o comando boot tftp://.
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

8. A tela deve ficar assim quando o CGR carregar a imagem do hipervisor e não puder inicializar a imagem do sistema.
