Installing the Reference Configuration File (RCF)

You can install the RCF after setting up the Nexus 9336C-FX2 switch for the first time.You can also use this procedure to upgrade your RCF version.

About this task

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.
Note: The procedure requires the use of both ONTAP commands and Cisco Nexus 9000 Series Switches commands; ONTAP commands are used unless otherwise indicated.

Procedure

  1. Display the cluster ports on each node that are connected to the cluster switches: network device-discovery show 
    cluster1::*> network device-discovery show

  7. Clean the configuration on switch cs2 and perform a basic setup.
    1. Clean the configuration. This step requires a console connection to the switch. 
      cs2# write erase
Warning: This command will erase the startup-configuration.
Do you wish to proceed anyway? (y/n)  [n] y
cs2# reload
This command will reboot the system. (y/n)?  [n] y
cs2#
    2. Perform a basic setup of the switch.
  8. Copy the RCF to the bootflash of switch cs2 using one of the following transfer protocols: FTP, TFTP, SFTP, or SCP. For more information on Cisco commands, see the appropriate guide in the Cisco Nexus 9000 Series NX-OS Command Reference guides.
    This example shows TFTP being used to copy an RCF to the bootflash on switch cs2:
    cs2# copy tftp: bootflash: vrf management
Enter source filename: Nexus_9336C_RCF_v1.6-Cluster-HA-Breakout.txt
Enter hostname for the tftp server: 172.22.201.50
Trying to connect to tftp server......Connection to Server Established.
TFTP get operation was successful
Copy complete, now saving to disk (please wait)...
  9. Apply the RCF previously downloaded to the bootflash.

    For more information on Cisco commands, see the appropriate guide in the Cisco Nexus 9000 Series NX-OS Command Reference guides.

    This example shows the RCF file Nexus_9336C_RCF_v1.6-Cluster-HA-Breakout.txt being installed on switch cs2:
    cs2# copy Nexus_9336C_RCF_v1.6-Cluster-HA-Breakout.txt running-config echo-commands
  10. Examine the banner output from the show banner motd command. You must read and follow these instructions to ensure the proper configuration and operation of the switch. 
    cs2# show banner motd

  11. Verify that the RCF file is the correct newer version: show running-config
    When you check the output to verify you have the correct RCF, make sure that the following information is correct:
    • The RCF banner
    • The node and port settings
    • Customizations
    The output varies according to your site configuration. Check the port settings and refer to the release notes for any changes specific to the RCF that you have installed.
  12. After you verify the RCF versions and switch settings are correct, copy the running-config file to the startup-config file.
    For more information on Cisco commands, see the appropriate guide in the Cisco Nexus 9000 Series NX-OS Command Reference guides.

    cluster1::*> network interface modify -vserver Cluster -lif * -auto-revert True
  21. Reboot switch cs1.You do this to trigger the cluster LIFs to revert to their home ports. You can ignore the “cluster ports down” events reported on the nodes while the switch reboots. 
    cs1# reload
This command will reboot the system. (y/n)?  [n] y
  22. Verify that the switch ports connected to the cluster ports are up.
