Installieren Sie die NX-OS-Software
Gehen Sie folgendermaßen vor, um die NX-OS-Software auf dem Nexus 9336C-FX2-Cluster-Switch zu installieren.
Bevor Sie beginnen, führen Sie den Vorgang in durch "Bereiten Sie sich auf die Installation von NX-OS und RCF vor".
Prüfen Sie die Anforderungen
-
Ein aktuelles Backup der Switch-Konfiguration.
-
Ein voll funktionsfähiges Cluster (keine Fehler in den Protokollen oder ähnlichen Problemen).
-
"Cisco Ethernet Switch Seite". In der Tabelle zur Switch-Kompatibilität finden Sie Informationen zu den unterstützten ONTAP- und NX-OS-Versionen.
-
Entsprechende Leitfäden für Software und Upgrades auf der Cisco Website für die Upgrade- und Downgrade-Verfahren von Cisco Switches. Siehe "Switches Der Cisco Nexus 9000-Serie".
Die Beispiele in diesem Verfahren verwenden die folgende Nomenklatur für Switches und Knoten:
-
Die Namen der beiden Cisco Switches sind cs1 und cs2.
-
Die Node-Namen sind cluster1-01, cluster1-02, cluster1-03 und cluster1-04.
-
Die Cluster-LIF-Namen sind Cluster1-01_clus1, cluster1-01_clus2, cluster1-02_clusions1, cluster1-02_clus2 , cluster1-03_clug1, Cluster1-03_clus2, cluster1-04_clut1, und cluster1-04_clus2.
-
Der
cluster1::*>
Eine Eingabeaufforderung gibt den Namen des Clusters an.
Installieren Sie die Software
Das Verfahren erfordert die Verwendung von ONTAP Befehlen und den Switches der Cisco Nexus 9000 Serie. ONTAP Befehle werden verwendet, sofern nicht anders angegeben.
-
Verbinden Sie den Cluster-Switch mit dem Managementnetzwerk.
-
Überprüfen Sie mit dem Ping-Befehl die Verbindung zum Server, der die NX-OS-Software und die RCF hostet.
Beispiel anzeigen
In diesem Beispiel wird überprüft, ob der Switch den Server unter der IP-Adresse 172.19.2 erreichen kann:
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.
-
Kopieren Sie die NX-OS-Software und EPLD-Bilder auf den Nexus 9336C-FX2-Switch.
Beispiel anzeigen
cs2# copy sftp: bootflash: vrf management Enter source filename: /code/nxos.9.3.5.bin Enter hostname for the sftp server: 172.19.2.1 Enter username: user1 Outbound-ReKey for 172.19.2.1:22 Inbound-ReKey for 172.19.2.1:22 user1@172.19.2.1's password: sftp> progress Progress meter enabled sftp> get /code/nxos.9.3.5.bin /bootflash/nxos.9.3.5.bin /code/nxos.9.3.5.bin 100% 1261MB 9.3MB/s 02:15 sftp> exit Copy complete, now saving to disk (please wait)...
