Install the NX-OS software
Follow this procedure to install the NX-OS software on the Nexus 9336C-FX2 cluster switch.
Before you begin, complete the procedure in Prepare to install NX-OS and RCF.
Review requirements
-
A current backup of the switch configuration.
-
A fully functioning cluster (no errors in the logs or similar issues).
-
Consult the switch compatibility table for the supported ONTAP and NX-OS versions.
-
Software Upgrade and downgrade guides
Refer to the appropriate software and upgrade guides available on the Cisco website for complete documentation on the Cisco switch upgrade and downgrade procedures.
-
Cisco Nexus 9000 and 3000 Upgrade and ISSU Matrix
Provides information on Disruptive Upgrade/Downgrade for Cisco NX-OS software on Nexus 9000 Series Switches based on your current and target releases.
On the page, select Disruptive Upgrade and select your current release and target release from the dropdown list.
The examples in this procedure use the following switch and node nomenclature:
-
The names of the two Cisco switches are cs1 and cs2.
-
The node names are cluster1-01, cluster1-02, cluster1-03, and cluster1-04.
-
The cluster LIF names are cluster1-01_clus1, cluster1-01_clus2, cluster1-02_clus1, cluster1-02_clus2 , cluster1-03_clus1, cluster1-03_clus2, cluster1-04_clus1, and cluster1-04_clus2.
-
The
cluster1::*>
prompt indicates the name of the cluster.
Install the software
The procedure requires the use of both ONTAP commands and Cisco Nexus 9000 Series Switches commands; ONTAP commands are used unless otherwise indicated.
-
Connect the cluster switch to the management network.
-
Use the ping command to verify connectivity to the server hosting the NX-OS software and the RCF.
Show example
This example verifies that the switch can reach the server at IP address 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.
-
Display the cluster ports on each node that are connected to the cluster switches:
network device-discovery show
Show example
