PDF
Siga este procedimiento para instalar el software NX-OS en el switch de clúster Nexus 9336C-FX2.
Antes de comenzar, complete el procedimiento en "Prepare la instalación de NX-OS y RCF".
Revise los requisitos
-
Una copia de seguridad actual de la configuración del switch.
-
Un clúster en pleno funcionamiento (sin errores en los registros o problemas similares).
-
"Página del switch Cisco Ethernet"
Consulte en la tabla de compatibilidad del switch las versiones ONTAP y NX-OS compatibles.
-
"Guías de actualización y degradación de software"
Consulte las guías de software y actualización correspondientes disponibles en el sitio web de Cisco para obtener documentación completa sobre los procedimientos de actualización y degradación del conmutador Cisco.
-
"Matriz de ISSU y actualización de Cisco Nexus 9000 y 3000"
Proporciona información sobre actualización/degradación disruptiva para software Cisco NX-OS en los switches de la serie Nexus 9000 en función de tus versiones actuales y objetivo.
En la página, selecciona Actualización disruptiva y selecciona tu versión actual y la versión de destino de la lista desplegable.
Los ejemplos de este procedimiento utilizan la nomenclatura de conmutador y nodo siguiente:
-
Los nombres de los dos switches de Cisco son cs1 y cs2.
-
Los nombres de nodo son cluster1-01, cluster1-02, cluster1-03 y cluster1-04.
-
Los nombres de las LIF del clúster son cluster1-01_clus1, cluster1-01_clus2, cluster1-02_clus1, cluster1-02_clus2 , cluster1-03_clus1, cluster1-03_clus2, cluster1-04_clus1 y cluster1-04_clus2.
-
La
cluster1::*>prompt indica el nombre del clúster.
Instale el software
Para ello, es necesario utilizar tanto comandos de la ONTAP como comandos de la serie Cisco Nexus 9000; los comandos de la ONTAP se usan a menos que se indique lo contrario.
-
Conecte el switch de clúster a la red de gestión.
-
Utilice el comando ping para verificar la conectividad con el servidor que aloja el software NX-OS y el RCF.
Muestra el ejemplo
Este ejemplo verifica que el switch puede llegar al servidor en la dirección 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.
