Migration requirements

If you have a two-node switchless cluster, you can migrate to a two-node switched cluster that includes Cisco Nexus 3232C cluster network switches. This is a nondisruptive procedure.

Before you begin

Verify the following installations and connections:

  • Ports are available for node connections. The cluster switches use the Inter-Switch Link (ISL) ports e1/31-32.

  • You have appropriate cables for cluster connections:

    • The nodes with 10 GbE cluster connections require QSFP optical modules with breakout fiber cables or QSFP to SFP+ copper breakout cables.

    • The nodes with 40/100 GbE cluster connections require supported QSFP/QSFP28 optical modules with fiber cables or QSFP/QSFP28 copper direct-attach cables.

    • The cluster switches require the appropriate ISL cabling:

      • 2x QSFP28 fiber or copper direct-attach cables.

  • The configurations are properly set up and functioning.

    The two nodes must be connected and functioning in a two-node switchless cluster setting.

  • All cluster ports are in the up state.

  • The Cisco Nexus 3232C cluster switch are supported.

  • The existing cluster network configuration has the following:

    • A redundant and fully functional Nexus 3232C cluster infrastructure on both switches

    • The latest RCF and NX-OS versions on your switches

    • Management connectivity on both switches

    • Console access to both switches

    • All cluster logical interfaces (LIFs) in the up state without having been migrated

    • Initial customization of the switch

    • All ISL ports enabled and cabled

About the examples used

The examples in this procedure use the following switch and node nomenclature:

  • Nexus 3232C cluster switches, C1 and C2.

  • The nodes are n1 and n2.

The examples in this procedure use two nodes, each using two 40 GbE cluster interconnect ports e4a and e4e. The Hardware Universe has details about the cluster ports on your platforms.

  • n1_clus1 is the first cluster logical interface (LIF) to be connected to cluster switch C1 for node n1.

  • n1_clus2 is the first cluster LIF to be connected to cluster switch C2 for node n1.

  • n2_clus1 is the first cluster LIF to be connected to cluster switch C1 for node n2.

  • n2_clus2 is the second cluster LIF to be connected to cluster switch C2 for node n2.

  • The number of 10 GbE and 40/100 GbE ports are defined in the reference configuration files (RCFs) available on the Cisco® Cluster Network Switch Reference Configuration File Download page.

Note

The procedure requires the use of both ONTAP commands and Cisco Nexus 3000 Series Switches commands; ONTAP commands are used unless otherwise indicated.
