Seguire questa procedura per installare il software NX-OS sullo switch condiviso Nexus 9336C-FX2.
Prima di iniziare, completare la procedura in"Prepararsi all'installazione di NX-OS e RCF" .
Requisiti di revisione
Assicurati di avere quanto segue:
-
Un backup attuale della configurazione dello switch.
-
Un cluster completamente funzionante (nessun errore nei log o problemi simili).
-
"Pagina dello switch Ethernet Cisco"
Consultare la tabella di compatibilità degli switch per le versioni ONTAP e NX-OS supportate.
-
"Guide per l'aggiornamento e il downgrade del software"
Per la documentazione completa sulle procedure di upgrade e downgrade degli switch Cisco , fare riferimento alle guide software e di aggiornamento appropriate disponibili sul sito Web Cisco .
-
"Aggiornamento Cisco Nexus 9000 e 3000 e matrice ISSU"
Fornisce informazioni sull'aggiornamento/downgrade dirompente per il software Cisco NX-OS sugli switch Nexus serie 9000 in base alle versioni correnti e di destinazione.
Nella pagina, seleziona Disruptive Upgrade e seleziona la versione corrente e quella di destinazione dall'elenco a discesa.
Gli esempi in 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 dei 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::*>il prompt indica il nome del cluster.
Installa il software
La procedura richiede l'uso sia dei comandi ONTAP sia dei comandi degli switch Cisco Nexus serie 9000; salvo diversa indicazione, vengono utilizzati i comandi ONTAP .
-
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 l'RCF.
Mostra esempio
Questo esempio verifica che lo switch possa raggiungere il server all'indirizzo IP 172.19.2.1:
cs2# ping 172.19.2.1 VRF management Pinging 172.19.2.1 with 0 bytes of data: Reply From 172.19.2.1: icmp_seq = 0. time= 5910 usec.
-
Visualizza le porte del cluster su ciascun nodo connesso agli switch del cluster:
