Siga este procedimento para instalar o software NX-os no switch de cluster Nexus 9336C-FX2.
Antes de começar, conclua o procedimento em "Prepare-se para instalar o NX-os e o RCF".
Rever os requisitos
-
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.
-
"Guias de atualização e downgrade de software"
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.
-
"Atualização do Cisco Nexus 9000 e 3000 e Matriz ISSU"
Fornece informações sobre atualização/downgrade disruptiva para o software Cisco NX-os em switches Nexus 9000 Series com base em suas versões atuais e de destino.
Na página, selecione Atualização disruptiva e selecione sua versão atual e liberação de destino na lista suspensa.
Os exemplos deste procedimento utilizam a seguinte nomenclatura de switch e nó:
-
Os nomes dos dois switches Cisco são CS1 e CS2.
-
Os nomes dos nós são cluster1-01, cluster1-02, cluster1-03 e cluster1-04.
-
Os nomes de LIF do cluster são cluster1-01_clus1, cluster1-01_clus2, cluster1-03_clus2, cluster1-03_clus1 , cluster1-02_clus2, cluster1-02_clus1, cluster1-04_clus1 e cluster1-04_clus2.
-
O
cluster1::*>prompt indica o nome do cluster.
Instale o software
O procedimento requer o uso de comandos ONTAP e comandos Cisco Nexus 9000 Series switches; os comandos ONTAP são usados, a menos que indicado de outra forma.
-
Conete o switch de cluster à rede de gerenciamento.
-
Use o comando ping 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.
-
Exiba as portas do cluster em cada nó conetado aos switches do cluster:
