Como já falado no post anterior, apesar de se parecer com o IOS, o NX-OS tem suas particularidades. Na hora do upgrade isso também é percebido.
No Nexus temos dois arquivos para atualizar (o kickstart e o system) e além de copiar os arquivos para a bootflash precisamos “instalá-los”.
Atualizando o Cisco Nexus 5000
1) Depois de logar no equipamento e verificar que há espaço suficiente (dir bootflash:) para as novas imagens, copie os arquivos para a bootflash. Podemos usar ftp, tftp, scp ou sftp para fazer a transferência. Informe o método selecionado (neste caso tftp), o nome do software e o IP do servidor.
BrainNexus5k# copy tftp: bootflash: vrf management
Enter source filename: n5000-uk9-kickstart.6.0.2.N2.1.bin
Enter hostname for the tftp server: 10.89.215.62
Trying to connect to tftp server……
Connection to Server Established.
TFTP get operation was successful
Copy complete, now saving to disk (please wait)…

Enter hostname for the tftp server: 10.89.215.62

2) Após copiar os arquivos precisamos “instalá-los”, com o comando install. A saber, este comando faz uma checagem de compatibilidade dos softwares que serão utilizados, permite que você escolha continuar ou não, atualiza as variáveis de boot para os novos softwares e ainda salva a configuração na startup-config.
BrainNexus5k# install all kickstart n5000-uk9-kickstart.6.0.2.N2.1.bin system bootflash:n5000-uk9.6.0.2.N2.1.bin

Observe que ao selecionar y (yes) o upgrade será realizado e o equipamento reiniciará.
Quando o equipamento ligar, logue-se e use o comando show version para verificar se o novo software está em uso.
