Instale o software NX-os

Colaboradores
PDFs

Você pode usar este procedimento para instalar o software NX-os no switch de cluster Nexus 3232C.

Rever os requisitos

Antes de começar

  • Um backup atual da configuração do switch.

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

  • "Página do 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

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 NX-os e o RCF"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

    Este exemplo verifica se o switch pode alcançar o servidor no endereço IP 172.19.2.1:

    cs2# ping 172.19.2.1
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

  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 e as imagens EPLD para o switch Nexus 3232C.

    Mostrar exemplo 
    cs2# copy sftp: bootflash: vrf management

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

    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.

  14. Verifique se o cluster está em bom estado:

    cluster show

    Mostrar exemplo 
    cluster1::*> cluster show

  15. Repita os passos 6 a 14 no interrutor CS1.

  16. Ative a reversão automática nos LIFs do cluster.

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

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

    network interface show -role cluster

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

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

    network interface revert -vserver Cluster -lif <lif_name>
