Instale o software NX-os

Colaboradores

Siga este procedimento para instalar o software NX-os no switch de cluster Nexus 3132Q-V.

Rever os requisitos

Antes de começar
  • Um backup atual da configuração do switch.

  • Um cluster totalmente funcional (sem erros nos logs ou problemas semelhantes).

Documentação sugerida
  • "Switch Ethernet Cisco". Consulte a tabela de compatibilidade do switch para ver as versões suportadas do ONTAP e NX-os.

  • "Switches Cisco Nexus 3000 Series". Consulte os guias de software e atualização apropriados disponíveis no site da Cisco para obter a documentação completa sobre os procedimentos de atualização e downgrade do switch Cisco.

Instale o software

Sobre esta tarefa

O procedimento requer o uso de comandos ONTAP e comandos Cisco Nexus 3000 Series switches; os comandos ONTAP são usados, a menos que indicado de outra forma.

Certifique-se de que conclui o procedimento em "Prepare-se para instalar o software NX-os e o ficheiro de configuração de referência"e, em seguida, siga os passos abaixo.

Passos
  1. Conete o switch de cluster à rede de gerenciamento.

  2. Use o ping comando para verificar a conetividade com o servidor que hospeda o software NX-os e o RCF.

    Mostrar exemplo
    cs2# ping 172.19.2.1 vrf management
    Pinging 172.19.2.1 with 0 bytes of data:
    
    Reply From 172.19.2.1: icmp_seq = 0. time= 5910 usec.
  3. Exiba as portas do cluster em cada nó conetado aos switches do cluster:

    network device-discovery show

    Mostrar exemplo
    cluster1::*> network device-discovery show
    Node/       Local  Discovered

  4. Verifique o status administrativo e operacional de cada porta de cluster.

    1. Verifique se todas as portas do cluster estão up com um status de integridade:

      network port show -role cluster

      Mostrar exemplo
      cluster1::*> network port show -role cluster

      8 entries were displayed.
      cluster1::*>
    3. Verifique se o cluster exibe informações para ambos os switches do cluster:

      system cluster-switch show -is-monitoring-enabled-operational true

    Mostrar exemplo
    cluster1::*> system cluster-switch show -is-monitoring-enabled-operational true
    Switch                      Type               Address          Model

        Version Source: CDP
    cluster1::*>
  5. Desative a reversão automática nos LIFs do cluster. Os LIFs de cluster fazem failover para o switch de cluster do parceiro e permanecem lá enquanto você executa o procedimento de atualização no switch de destino:

    network interface modify -vserver Cluster -lif * -auto-revert false

  6. Copie o software NX-os para o switch Nexus 3132Q-V usando um dos seguintes protocolos de transferência: FTP, TFTP, SFTP ou SCP. Para obter mais informações sobre comandos Cisco, consulte o guia apropriado no "Guias de referência de comando Cisco Nexus 3000 Series NX-os".

    Mostrar exemplo
    cs2# copy sftp: bootflash: vrf management
    Enter source filename: /code/nxos.9.3.4.bin
    Enter hostname for the sftp server: 172.19.2.1
    Enter username: user1
    
    Outbound-ReKey for 172.19.2.1:22
    Inbound-ReKey for 172.19.2.1:22

    sftp> exit
    Copy complete, now saving to disk (please wait)...
    Copy complete.
  7. Verifique a versão em execução do software NX-os:

    2. Verifique a integridade do switch a partir do cluster.

      network device-discovery show -protocol cdp

    Mostrar exemplo
    cluster1::*> network device-discovery show -protocol cdp

    Você pode observar a seguinte saída no console do switch CS1, dependendo da versão RCF carregada anteriormente no switch:

    2020 Nov 17 16:07:18 cs1 %$ VDC-1 %$ %STP-2-UNBLOCK_CONSIST_PORT: Unblocking port port-channel1 on VLAN0092. Port consistency restored.

    2020 Nov 17 16:07:23 cs1 %$ VDC-1 %$ %STP-2-BLOCK_PVID_LOCAL: Blocking port-channel1 on VLAN0092. Inconsistent local vlan.
  11. Verifique se o cluster está em bom estado:

    cluster show

    Mostrar exemplo
    cluster1::*> cluster show
    Node                 Health   Eligibility   Epsilon
    -------------------- -------- ------------- -------

    cluster1-03          true     true          true
    cluster1-04          true     true          false
    4 entries were displayed.
    cluster1::*>
  12. Repita os passos 6 a 11 no interrutor CS1.

  13. Ative a reversão automática nos LIFs do cluster.

    network interface modify -vserver Cluster -lif * -auto-revert true

  14. Verifique se os LIFs do cluster reverteram para sua porta inicial:

    network interface show -role cluster

    Mostrar exemplo
    cluster1::*> network interface show -role cluster
                Logical            Status     Network            Current             Current Is

    cluster1::*>

    Se qualquer LIFs de cluster não retornar às portas iniciais, reverta-as manualmente do nó local:

    network interface revert -vserver Cluster -lif <lif_name>
