Installare il software NX-OS
Seguire questa procedura per installare il software NX-OS sullo switch del cluster Nexus 9336C-FX2.
Prima di iniziare, completare la procedura descritta in "Preparazione all'installazione di NX-OS e RCF".
Verifica dei requisiti
-
Backup corrente della configurazione dello switch.
-
Un cluster completamente funzionante (nessun errore nei log o problemi simili).
-
"Pagina switch Ethernet Cisco"
Consultare la tabella di compatibilità degli switch per le versioni supportate di ONTAP e NX-OS.
-
"Guide all'aggiornamento e al downgrade del software"
Per la documentazione completa sulle procedure di aggiornamento e di downgrade degli switch Cisco, consultare le guide appropriate per il software e l'aggiornamento disponibili sul sito Web di Cisco.
-
"Upgrade di Cisco Nexus 9000 e 3000 e matrice ISSU"
Fornisce informazioni su Disruptive Upgrade/Downgrade del software Cisco NX-OS sugli switch della serie Nexus 9000 in base alle release attuali e a quelle di destinazione.
Nella pagina, selezionare Disruptive Upgrade (aggiornamento distruttivo) e selezionare la release corrente e la release di destinazione dall'elenco a discesa.
Gli esempi di questa procedura utilizzano la seguente nomenclatura di switch e nodi:
-
I nomi dei due switch Cisco sono cs1 e cs2.
-
I nomi dei nodi sono cluster1-01, cluster1-02, cluster1-03 e cluster1-04.
-
I nomi LIF del cluster sono cluster1-01_clus1, cluster1-01_clus2, cluster1-02_clus1, cluster1-02_clus2 , cluster1-03_clus1, cluster1-03_clus2, cluster1-04_clus1 e cluster1-04_clus2.
-
Il
cluster1::*>
prompt indica il nome del cluster.
Installare il software
La procedura richiede l'utilizzo di entrambi i comandi ONTAP e Cisco Nexus 9000 Series Switches; i comandi ONTAP vengono utilizzati se non diversamente indicato.
-
Collegare lo switch del cluster alla rete di gestione.
-
Utilizzare il comando ping per verificare la connettività al server che ospita il software NX-OS e RCF.
Questo esempio verifica che lo switch possa raggiungere il server all'indirizzo 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.
-
Copia il software NX-OS e le immagini EPLD sullo switch Nexus 9336C-FX2.
