Este documento descreve as etapas necessárias para substituir um servidor de computação defeituoso em uma configuração Ultra-M que hospeda as VNFs (Virtual Network Functions, funções de rede virtual) do StarOS.
O Ultra-M é uma solução de núcleo de pacotes móveis virtualizados, pré-embalada e validada, projetada para simplificar a implantação de VNFs. O OpenStack é o Virtualized Infrastructure Manager (VIM) para Ultra-M e consiste nos seguintes tipos de nó:
A arquitetura de alto nível da Ultra-M e os componentes envolvidos estão descritos nesta imagem:
Este documento destina-se ao pessoal da Cisco familiarizado com a plataforma Cisco Ultra-M e detalha as etapas necessárias para serem executadas no nível de VNF do OpenStack e do StarOS no momento da substituição do servidor de computação.
Note: A versão Ultra M 5.1.x é considerada para definir os procedimentos neste documento.
VNF | Função de rede virtual |
CF | Função de controle |
SF | Função de serviço |
ESC | Controlador de serviço elástico |
MOP | Método de Procedimento |
OSD | Discos de Armazenamento de Objeto |
HDD | Unidade de disco rígido |
SSD | Unidade de estado sólido |
VIM | Virtual Infrastructure Manager |
VM | Máquina virtual |
EM | Gestor de Elementos |
UAS | Ultra Automation Services |
UUID | Identificador de ID universal exclusivo |
Antes de substituir um nó de computação, é importante verificar o estado atual do ambiente da plataforma Red Hat OpenStack. É recomendável verificar o estado atual para evitar complicações quando o processo de substituição de computação estiver ativado. Isso pode ser feito por meio desse fluxo de substituição.
Em caso de recuperação, a Cisco recomenda fazer um backup do banco de dados OSPD com o uso destas etapas:
[root@director ~]# mysqldump --opt --all-databases > /root/undercloud-all-databases.sql
[root@director ~]# tar --xattrs -czf undercloud-backup-`date +%F`.tar.gz /root/undercloud-all-databases.sql
/etc/my.cnf.d/server.cnf /var/lib/glance/images /srv/node /home/stack
tar: Removing leading `/' from member names
Esse processo garante que um nó possa ser substituído sem afetar a disponibilidade de quaisquer instâncias. Além disso, é recomendável fazer backup da configuração do StarOS, especialmente se o nó de computação a ser substituído hospeda a Máquina Virtual (VM) da Função de Controle (CF).
Identifique as VMs hospedadas no servidor de computação. Podem existir duas possibilidades:
[stack@director ~]$ nova list --field name,host | grep compute-10

Note: Na saída mostrada aqui, a primeira coluna corresponde ao UUID (Universal Unique IDentifier), a segunda coluna é o nome da VM e a terceira coluna é o nome do host onde a VM está presente. Os parâmetros dessa saída serão usados em seções subsequentes.

Crie um arquivo add_node.json com apenas os detalhes do novo servidor de computação a ser adicionado. Verifique se o número de índice do novo servidor de computação não foi usado antes. Geralmente, aumente o próximo valor de computação mais alto.
Exemplo: O anterior mais alto foi o computador-17, portanto, criou o computador-18 no caso do sistema de 2 vnf.

Salve a linha boot_vm.py em um arquivo de script shell (esc.sh) e atualize todas as linhas de nome de usuário ***** e senha ***** com as informações corretas (tipicamente core/<PASSWORD>). Você também precisa remover a opção -encrypt_key. Para user_pass e user_confd_pass, você precisa usar o formato - nome de usuário: password (exemplo - admin:<PASSWORD>).

Nos casos em que o ESC não inicia a VM devido a um estado inesperado, a Cisco recomenda executar um switchover ESC reiniciando o ESC mestre. A transição para o ESC levaria cerca de um minuto. Execute o script "health.sh" no novo ESC principal para verificar se o status está ativo. Mestre ESC para iniciar a VM e corrigir o estado da VM. Essa tarefa de recuperação levaria até 5 minutos para ser concluída.
Você pode monitorar /var/log/esc/yangesc.log e /var/log/esc/escmanager.log. Se você NÃO vir a VM sendo recuperada após 5 a 7 minutos, o usuário precisaria ir e fazer a recuperação manual das VMs afetadas.
Em AutoDeploy VM, edite o autoDeployment.cfg e substitua o servidor de computação antigo pelo novo. Em seguida, carregar substituir em confd_cli. Esta etapa é necessária para uma desativação de implantação bem-sucedida posteriormente.
