Analisar problemas de Dependência da Plataforma (PD) Triaging Fretta

Introdução

Este documento descreve as diretrizes sobre como analisar e localizar as causas raiz de problemas dependentes de plataforma na família de roteadores Fretta (NCS5500). 

Logs a serem coletados

Para quaisquer triagens dependentes de plataforma, colete os registros básicos listados abaixo. Dependendo do componente suspeito ou da área de funcionalidade, colete outros logs, além dos logs básicos, conforme indicado nas subseções abaixo.

Logs básicos a serem coletados

• show logging
• show tech ctrace
• show tech card-mgr
• show tech shelf-mgr
• show tech os
• show tech obfl

Logs de Erros de Pulsação

• show tech heart-beat miss

Logs relacionados a EOBC/EPC

Consulte os problemas específicos do EOBC/EPC de destino.

• show tech control-ethernet

Relacionado à Malha

• show tech fabric de xrvm

Gerenciador de fatias

• show tech-support sdr_mgr
• show tech-support install
• show tech-support fabric
• show tech-support fpd
• show tech-support cm
• show controller fabric health
• show platform slices

Gerenciador de MPA

• show tech-support mpa-mgr

LED

Detalhes

Análise usando registros de gerenciamento de cartões

• Reserve um tempo para acessar o wiki detalhado do Card Manager em 
• Para depurar qualquer problema de plataforma, você precisa usar os logs show tech ctrace, show tech card-mgr e show tech shelf_mgr para entender o que está acontecendo.
• show reboot-history card location <> dos logs do shelf_mgr fornece o histórico de reinicialização da placa.
• show controllers card-mgr event-history brief location <> e show controllers card-mgr event-history detail location <> dos logs show tech card-mgr fornecem detalhes sobre os detalhes da máquina de estado do fsm do card-mgr.
• Quando uma placa falha na inicialização, é necessário examinar o histórico de eventos dessa placa e, com base no estado/evento em que a placa está travada/falhou, é necessário verificar com o ponto de vista do BIOS, da instalação PD ou do gerenciador de placas. Cada evento tem um código postal associado, que fornece pistas para o movimento FSM.

Note: Se uma placa de linha falhar ao inicializar e passar para o estado FAILED/FAILED, você precisará se conectar ao console da placa de linha após forçar o recarregamento da placa. Isso o ajuda a entender por que a placa de linha não consegue inicializar. show tech não pode coletar logs de uma placa de linha com falha.

Consulte o wiki detalhado do gerente de cartões mencionado acima para entender o significado dos detalhes específicos de estado, evento e código postal. Consulte também o arquivo card manger smil localizado em calvados/dc_common_pkg/drivers/card_mgr/card_mgr_fsm.smil. Esse arquivo tem uma boa descrição dos estados, eventos e transição de estado do FSM.

Aqui está um exemplo de saída resumida de histórico de eventos de caso de trabalho quando um LC é redefinido a frio:

Usar show tech ctrace para fazer a Análise Offline

Decodificar ctrace offline no Servidor de Anúncios

1. Copie o arquivo do show tech ctrace para um diretório no servidor de anúncios.
2. Descompacte o conteúdo do arquivo usando - tar zxvf showtech-ctrace-admin-2019-Nov-06.174210.UTC.tgz
3. cd showtech-ctrace-admin-2019-nov-06.174210.UTC
4. Use este comando para decodificar os rastreamentos do processo card_mgr no diretório cmgr: /users/gonaidu/bin/showtech_ct_dec -d cmgr -p card_mgr
5. cd cmgr

Note: Os logs decodificados do ctrace estão no fuso horário local - Se a decodificação foi feita no servidor ADS Bangalore, os ctraces são baseados no fuso horário IST. Lembre-se disso ao comparar os logs do roteador e os logs de rastreamento decodificados off-line.

Identificar o SC principal e o SUP principal

Use "grep "Master Role" *" no diretório do cmgr:

card_mgr.0_RP0:299:2019-02-22:07.35.38.709224844:2580:calvados/dc_common_pkg/drivers/card_mgr/src/card_mgr_main.c:1539:main:cmgr_main:MAIN_HW_ARB_RESULT:[MAIN]: HW Arbitration Result = Master Role
card_mgr.0_SC0:96:2019-04-06:19.04.34.500975616:1976:calvados/dc_common_pkg/drivers/card_mgr/src/card_mgr_main.c:1539:main:cmgr_main:MAIN_HW_ARB_RESULT:[MAIN]: HW Arbitration Result = Master Role

Recuperar códigos postais do SC principal

 Use este comando para obter códigos de post para LC 0/1: grep "slot 2" card_mgr.0_SC0 | grep alterado

2019-04-06:19.04.34.759844864:1976:calvados/dc_common_pkg/drivers/card_mgr/src/card_mgr_interrupt.c:256:iofpga_check_card_post_code_change:cmgr_isr:ISR_CARD_POST_CODE_CHANGED:[ISR]: POST Code for slot 2 changed to 0xa0

Histórico de eventos do ponto de vista do RP principal:

Como Receber, Editar e Criar Lineup Satori?

Pode haver várias linhagens coexistentes. O engenheiro precisa saber de onde ele deve obter a exibição. Para saber a linha satori/devline apropriada, no prompt sysadmin linux, execute este comando

cat /etc/build-info.txt

Você obtém a saída assim

Before pulling the view, setup your environment

Etapa 2. Certifique-se de que esta entrada esteja presente no seu arquivo de configuração git ie; ~/.gitconfig

[aplicar]

    espaço em branco = nowarn

    ignorewhitespace = change

Etapa 3. Use este comando para configurar seu ambiente antes de realizar qualquer atividade

source /auto/exr-yocto/tools/scripts/set_yocto_env

Etapa 4. Use este comando para extrair a exibição.

acme pull -sb ios_ena -dev cisco-xr-wr7 -plat none

Etapa 5. Executar o comando abaixo no shell

unset CDPATH

Comando para criar o kernel

Etapa 1. Navegue até o diretório satori e execute este comando.

scripts/xr/build-release.sh -f

Etapa 2. Depois que o kernel for criado com êxito, ele aplicará os patches específicos da cisco a vários arquivos .c e .h e o código se tornará disponível nesse caminho para code walk.

satori/target-n9000-gdb/bitake_build/tmp/work/n9000_gdb-wrs-linux/

Note: você não deve fazer nenhuma alteração permanente aqui para ser refletido em seu binário porque esse é o local tmp e deve ser substituído na próxima compilação. O código neste local deve ser usado para code walk e geração de arquivo .patch. O arquivo .patch é discutido aqui

Do ponto de vista da localização do código, o código para klm está localizado em dois caminhos

• Para caminhadas de código e geração de patch:

satori/target-n9000-gdb/bitake_build/tmp/work/n9000_gdb-wrs-linux/

• Arquivos reais .c e .h que são usados em compilações binárias/sdk

satori/meta-cisco-nxos/recipes-kernel/

No caminho acima, você obtém dois diretórios

A. cisco-klm —> Isso abrange todos os klm que são usados em sistemas fretta modulares e fixos.

B. cisco-klm-zermatt —> Isso abrange todos os klm que são usados somente em sistemas fretta fixos como klm_iofpga.

Como fazer as alterações para diferentes klms e obtê-lo compilado?

Fazer alterações para klm_iofpga é muito simples. Basta ir para esse caminho e começar a fazer alterações no arquivo .c ou .h no qual você está interessado.

satori/target-n9000-gdb/bitake_build/tmp/work/n9000_gdb-wrs-linux/cisco-klm-zermatt/0.1-r0/klm_iofpga

Fazer alterações em todos os outros klm(s) é um pouco complicado. Como explicado acima, você precisa ir para o local tmp, fazer as alterações, gerar o arquivo .patch (como gerar um arquivo .patch é explicado aqui). Copie o arquivo .patch para um local específico, faça uma entrada para esse novo arquivo .patch no arquivo .bb e inicie a compilação.

Localize as etapas para fazer as alterações.

Etapa 1. Vá para o diretório específico do klm onde deseja fazer as alterações. Você encontra todos os klms neste local.

satori/target-n9000-gdb/bitake_build/tmp/work/n9000_gdb-wrs-linux/cisco-klm/0.1-r0

Etapa 2. Use a ferramenta quilt para fazer as alterações, de modo que o arquivo .patch possa ser gerado. Observe que aqui veio diff não funciona, então você precisa usar a ferramenta de colcha para gerar o arquivo de patch.

Etapa 3. Configurar o alias da ferramenta de colcha

cd satori/target-n9000-gdb/bitake_build/tmp/work/n9000_gdb-wrs-linux/cisco-klm/0.1-r0

alias quilt=/nobackup/rpanday/kernel-wr7/satori/target-n9000-gdb/bitake_build/tmp/sysroots/x86_64-linux/usr/bin/quilt

quilt new patch_file.patch —> Instrua o quilt a alocar um novo arquivo .patch com o nome patch_file.patch.

quilt top —> Este comando informa que o patch_file.patch está no topo da pilha do quilt e pronto para ser editado.

quilt edit klm_obfl/obfl_dc3.c —-> Instrua o quilt a capturar as alterações feitas em klm_obfl/obfl_dc3.c. Uma vez executado esse comando, obfl_dc3.c fica aberto e pronto para edição. Depois que as edições estiverem concluídas, escreva e saia.

quilt refresh —-> Este comando pega o diff do arquivo editado klm_obfl/obfl_dc3.c e o coloca em patch_file.patch. Para verificar o mesmo, abra o arquivo no vi.

Etapa 4. Depois que o arquivo de patch patch patch patch_file.patch for gerado, copie-o para esse caminho.

cp patches/patch_file.patch /nobackup/rpanday/kernel-wr7/satori/meta-cisco-nxos/recipes-kernel/cisco-klm/files

Etapa 5. Faça uma entrada no arquivo .bb para este novo arquivo .patch. O arquivo .bb está localizado nesse local.

/nobackup/rpanday/kernel-wr7/satori/meta-cisco-nxos/recipes-kernel/cisco-klm/cisco-klm_0.1.bb
