Installing NX-OS software and RCFs on Cisco Nexus 9336C-FX2 cluster switches

The Cisco NX-OS software and reference configuration files (RCFs) must be installed on Cisco Nexus 9336C-FX2 cluster switches.

The following conditions must exist before you install the NX-OS software and Reference Configurations Files (RCFs) on the cluster switch:
  • The cluster must be fully functioning (there should be no errors in the logs or similar issues).
  • You must have checked or set your desired boot configuration in the RCF to reflect the desired boot images if you are installing only NX-OS and keeping your current RCF version.
  • If you need to change the boot configuration to reflect the current boot images, you must do so before reapplying the RCF so that the correct version is instantiated on future reboots.
  • You must have a console connection to the switch, required when installing the RCF.
  • Consult the compatible ONTAP and NX-OS versions in the change list.
  • There can be command dependencies between the command syntax in the RCF and that found in versions of NX-OS.
  • You must have referred to the appropriate software and upgrade guides available on the Cisco web site for complete documentation on the Cisco switch upgrade and downgrade procedures on Cisco Nexus 9000 Series Switches.

  • You must have the current RCF.

    To download the RCF file, go to Lenovo Data Center Support.

The examples in this procedure use two nodes. These nodes use two 10GbE cluster interconnect ports e0a and e0b.

See the Lenovo Press to verify the correct cluster ports on your platforms.

Note
The command outputs might vary depending on different releases of ONTAP.
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 and cluster1-02.
  • The cluster LIF names are cluster1-01_clus1 and cluster1-01_clus2 for cluster1-01 and cluster1-02_clus1 and cluster1-02_clus2 for cluster1-02.
  • 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.
  1. If AutoSupport is enabled on this cluster, suppress automatic case creation by invoking an AutoSupport message: system node autosupport invoke -node * -type all -message MAINT=x h

    In MAINT=x h, x is the duration of the maintenance window in units of hours.

    Note
    The AutoSupport message notifies technical support of this maintenance task so that automatic case creation is suppressed during the maintenance window.
  2. Change the privilege level to advanced, entering y when prompted to continue:
    set -privilege advanced

    The advanced prompt (*>) appears.

  3. Display how many cluster interconnect interfaces are configured in each node for each cluster interconnect switch: network device-discovery show -protocol cdp
    cluster1::*> network device-discovery show -protocol cdp
