Hiperverificação: Hyperflex Health & Ferramenta de verificação de pré-atualização

Introduction

Este documento descreve o processo para executar a ferramenta Hypercheck Health & Pre-Upgrade. Essa ferramenta é um utilitário para executar autoverificações proativas em sistemas hiperflex para garantir sua estabilidade e resiliência. Ele ajuda a automatizar uma lista de verificações de integridade e pré-atualização em sistemas hiperflex para economizar tempo durante operações de atualização e manutenção de hiperflex.

NOTA: Faça sempre o download da versão mais recente da ferramenta antes de usá-la. Como a ferramenta é aprimorada com frequência, o uso de versões mais antigas pode resultar na falta de verificações importantes.

Sistemas HX suportados 

• Versões hiperflex - 1.8, 2.0, 2.1, 2.5, 2.6, 3.0, 3.5, 4.0, 4.5
• Cluster padrão Hyperflex
• Cluster estendido hiperflex
• Cluster de borda hiperflex (2 nós, 3 nós e 4 nós)
• Suportado somente no cluster Hyperflex no VMWare ESXi

NOTA: Como executar o Hypercheck no cluster HyperV hiperflex, Visite -

https://www.cisco.com/c/en/us/support/docs/hyperconverged-infrastructure/hyperflex-hx-data-platform/216027-hypercheck-hyperflex-health-pre-upgr.html

Quando usar

• Antes das atualizações do Hyperflex.
• Verificação de Integridade do Hyperflex antes e depois das Janelas de Manutenção
• Para identificar unidades/discos com falha.
• Ao trabalhar com o Cisco TAC
• Verificação de integridade pró-ativa a qualquer momento.

How to Use

HX versão 4.5

Etapa 1. SSH para a VM do controlador de armazenamento (SCVM) com o IP de gerenciamento de cluster (CMIP) que é o IP de conexão HX.

Etapa 2. Execute o comando "hypercheck"

admin:~$ hypercheck

Etapa 3. Insira a senha do administrador SCVM quando solicitado e, em seguida, insira a senha raiz do ESXI.

admin:~$ hypercheck

                  HX Health Check 4.5.0

Please enter below info of HX-Cluster:
Enter the HX-Cluster Admin Password:
Enter the ESX Root Password:

HX versão 4.0 e inferior

Etapa 1. Baixe o Hyperflex-Hypercheck.zip da conta do Cisco github devnet aqui. Obtenha a cópia mais recente que terá as melhorias e atualizações mais recentes. 

NOTA: Use apenas o script baixado da conta do Cisco github devnet.

Etapa 2. Faça o upload para a VM do controlador de armazenamento (SCVM) com o IP de gerenciamento de cluster (CMIP)

Use seu método preferido - scp/sftp/ftp/tftp - para copiar o Hyperflex-Hypercheck.zip para o diretório /tmp

Para MAC:

Execute o SCP a partir da CLI (confirme se o Hyperflex-Hypercheck.zip está na mesma pasta a partir da qual você está executando o scp)

# scp Hyperflex-Hypercheck.zip root@<scvm-eth0:mgmtip>:/tmp/

Utilize o seguinte para identificar o IP de Gerenciamento de Cluster em seu ambiente HX - manual do Hyperflex

Para Windows:

Podemos usar o WINSCP para transferir os arquivos conforme mostrado abaixo-

Etapa 3. Extraia o conteúdo do Hyperflex-Hypercheck.zip

Digite cd /tmp para alterar para o diretório /tmp 

root@SpringpathController7PVQWP6WV1:~# cd /tmp/

Digite unzip Hyperflex-Hypercheck.zip para extrair os arquivos 

root@SpringpathController7PVQWP6WV1:/tmp# unzip Hyperflex-Hypercheck.zip 
Archive:  Hyperflex-Hypercheck.zip

Etapa 4. Executar o script do Python HXTool

Digite cd Hyperflex-Hypercheck para ir para o diretório Hyperflex-Hypercheck 

root@SpringpathControllerABCDE01234:/tmp# cd Hyperflex-Hypercheck

Digite python HXTool.py para executar o script 

root@SpringpathControllerABCDE01234:/tmp/Hyperflex-Hypercheck# python HXTool.py

Etapa 5. Insira a senha raiz do SCVM quando solicitado 

Please enter below info of HX-Cluster:
Enter the HX-Cluster Root Password:
Enter the ESX Root Password:

NOTA: Para interromper a execução do script, use a tecla [CTRL+Z] e ela será interrompida imediatamente

Etapa 6. A ferramenta Hyperflex-Hypercheck inicia suas verificações. A conclusão da execução levará de 3 a 10 minutos, dependendo do número de nós convergentes no cluster

Passo 7. Obtenha um relatório das saídas do script. Você pode obtê-lo como mostrado abaixo,

O arquivo tar do relatório de hiperverificação é salvo em /var/log/springpath e /tmp/Hyperflex-Hypercheck. Assim, você pode fazer o download do pacote tar em /var/log/springpath ou/tmp/Hyperflex-Hypercheck. Como alternativa, você pode simplesmente gerar e carregar um pacote de suporte a storfs que também conterá o tar do relatório de hiperverificação.

Exemplo de arquivo tar de relatório - HX_Report_2020_08_30_10_43_50.tar é copiado para o caminho: /var/log/springpath

Digite ls -l | grep HX_Report para revisar os arquivos criados pela ferramenta Hyperflex-Hypercheck

Under /var/log/springpath,

root@SpringpathControllerABCDE01234:/var/log/springpath# ls -l | grep HX_Report
-rw-r--r-- 1 root root 380K Sep 23 15:41 HX_Report_2020_08_30_10_43_50.tar
root@SpringpathControllerABCDE01234:/var/log/springpath#

Under /tmp/Hyperflex-Hypercheck,

root@SpringpathControllerABCDE01234:/tmp/Hyperflex-Hypercheck# ls
HX_Report_2020_08_30_10_43_50.tar prettytable.py HX_Report_2020_08_30_10_43_50 TestInfo.txt progressbar.py
HXTool.py prettytable.pyc ReadMe.txt progressbar.pyc LICENSE.txt
root@SpringpathControllerABCDE01234:/tmp/Hyperflex-Hypercheck# 

Arquivos e registros no pacote de log do Hypercheck-

root@SpringpathControllerABCDE01234:/tmp/Hyperflex-Hypercheck# ls HX_Report_2020_08_30_10_43_50/
HX_Tool_2020-08-30_10-43-50.log 
HX_Tool_Main_Report_2020-08-30_10-54-34.txt 
HX_Tool_Summary.json

Etapa 8. Exporte HX_YYY_MM_DD_HH_MM_SS.tar e compartilhe-o com o TAC.

Use seu método preferido para exportar os registros de Hypercheck usando scp/sftp/ftp/tftp do SCVM ou você pode simplesmente fazer o download do pacote de suporte de storfs que conterá o pacote tar HX_Report.

Note:
1) If upgrading to HX 4.0(2a), please review the following link and perform workaround – https://tinyurl.com/wc7j5qp
2) Please check the status of Compute nodes manually, script only verifies the config on the converged nodes.
3) Hypercheck doesnot perform FAILOVER TEST, so please ensure that the upstream is configured for network connectivity for JUMBO or NORMAL MTU size as needed.

Analisar a saída da ferramenta - Próximas etapas

• A ferramenta automatiza o processo de execução de comandos manuais em sistemas Hyperflex.
• Se a ferramenta executar OK e fornecer PASS em todos os testes. O sistema HX é bom para todas as verificações que o script executou.
• Em situações em que a ferramenta FALHA em algumas verificações ou não é executada com êxito, você pode usar os comandos CLI (listados abaixo) para executar as mesmas verificações no Hyperflex System feitas pelo script Manually.
• A ferramenta NÃO verifica se há advertências antigas/novas/abertas/resolvidas e, portanto, é altamente recomendável rever as Notas de versão do Hyperflex e os Guias de atualização antes de qualquer atividade de atualização ou manutenção.

OBSERVAÇÃO: NÃO abra um caso no TAC porque o script não pôde ser executado. Execute os comandos manualmente, identifique o problema e abra um SR para o problema identificado.

Comandos CLI

No Hyperflex SCVM-

SSH to All Hyperflex SCVMs-

# service_status.sh

# sysmtool --ns cluster --cmd enospcinfo

# echo srvr | nc 0 2181

# pidof exhibitor

# stcli disk list --ip <Corresponding ESXi Mgmt IP Address> |grep -B 2 -A 8 blacklisted

# stcli services dns show (and ping the IPs listed)

# ping <vCenter IP Address>

# date ; compare the time on all SCVMs. They should ideally be identical

# stcli services ntp show

# stcli cleaner info

# ntpq -p -4 

# dpkg -l | grep -i springpath 

# iptables -L -n | wc -l 

# stcli cluster info

# df -h ; check that /var/stv should be less than 80%

# zgrep -i “out of memory” /var/log/springpath/debug-storfs.*

# ping -I eth0 <eth0> of all SCVMs

# ping -I eth1 <eth1> of all SCVMs

# "ls -ld /tmp" check for 775 and 777

# stcli cluster info | grep -i 'clusterAccessPolicy:' | head -1

# md5sum /etc/springpath/secure/springpath_keystore.jceks

# cat /etc/springpath/sed_capability.conf

# cat /etc/springpath/sed.conf

# cat /var/log/springpath/diskslotmap-v2.txt

# stcli cluster info | grep dataZkIp (ping dataZkIp for latency)

Em sistemas ESXi-

SSH to all ESXi hosts

# esxcli system account list

# esxcli network firewall ruleset list | grep -i vMotion

# esxcli software vib list| grep -i spring 

# esxcfg-vmknic -l ; confirm that vMotion VMK2 is created

# vmkping -I vmk1 <eth1> of all SCVMs

# cd /vmfs/volumes/Springpath-XXXXXXXXXX ; Ensure that it has only one Folder that has the Storage Controller VM

# df -h | grep vfat  ; Ensure dir has free space
