Follow these steps to configure your ports for migration from the Nexus 5596 switches to the new Nexus 3232C switches.

Steps

  1. Shut down the cluster interconnect ports that are physically connected to switch CL2:

    network port modify -node node-name -port port-name -up-admin false

    Show example

    The following commands shut down the specified ports on n1 and n2, but the ports must be shut down on all nodes:

    cluster::*> network port modify -node n1 -port e0b -up-admin false
cluster::*> network port modify -node n1 -port e0c -up-admin false
cluster::*> network port modify -node n2 -port e0b -up-admin false
cluster::*> network port modify -node n2 -port e0c -up-admin false

  2. Verify the connectivity of the remote cluster interfaces:

ONTAP 9.9.1 and later

You can use the network interface check cluster-connectivity command to start an accessibility check for cluster connectivity and then display the details:

network interface check cluster-connectivity start and network interface check cluster-connectivity show

cluster1::*> network interface check cluster-connectivity start

NOTE: Wait for a number of seconds before running the show command to display the details.

cluster1::*> network interface check cluster-connectivity show

       3/5/2022 19:21:20 -06:00   n1_clus2         n2_clus2         none

       3/5/2022 19:21:18 -06:00   n2_clus2         n1_clus1         none
       3/5/2022 19:21:20 -06:00   n2_clus2         n1_clus2         none
All ONTAP releases

For all ONTAP releases, you can also use the cluster ping-cluster -node <name> command to check the connectivity:

cluster ping-cluster -node <name>

  1. Shut down ISLs 41 through 48 on CL1, the active Nexus 5596 switch, using the Cisco shutdown command.

    For more information on Cisco commands, see the appropriate guide in the Cisco Nexus 3000 Series NX-OS Command References.

    Show example

    The following example shows ISLs 41 through 48 being shut down on the Nexus 5596 switch CL1:

    (CL1)# configure
(CL1)(Config)# interface e1/41-48
(CL1)(config-if-range)# shutdown
(CL1)(config-if-range)# exit
(CL1)(Config)# exit
(CL1)#

  2. Build a temporary ISL between CL1 and C2 using the appropriate Cisco commands.

    For more information on Cisco commands, see the appropriate guide in the Cisco Nexus 3000 Series NX-OS Command References.

    Show example

    The following example shows a temporary ISL being set up between CL1 and C2:

    C2# configure
C2(config)# interface port-channel 2
C2(config-if)# switchport mode trunk
C2(config-if)# spanning-tree port type network
C2(config-if)# mtu 9216
C2(config-if)# interface breakout module 1 port 24 map 10g-4x
C2(config)# interface e1/24/1-4
C2(config-if-range)# switchport mode trunk
C2(config-if-range)# mtu 9216
C2(config-if-range)# channel-group 2 mode active
C2(config-if-range)# exit
C2(config-if)# exit

  3. On all nodes, remove all cables attached to the Nexus 5596 switch CL2.

    With supported cabling, reconnect disconnected ports on all nodes to the Nexus 3232C switch C2.

  4. Remove all the cables from the Nexus 5596 switch CL2.

    Attach the appropriate Cisco QSFP to SFP+ break-out cables connecting port 1/24 on the new Cisco 3232C switch, C2, to ports 45 to 48 on existing Nexus 5596, CL1.

  5. Bring up ISLs ports 45 through 48 on the active Nexus 5596 switch CL1.

    For more information on Cisco commands, see the appropriate guide in the Cisco Nexus 3000 Series NX-OS Command References.

    Show example

    The following example shows ISLs ports 45 through 48 being brought up:

    (CL1)# configure
(CL1)(Config)# interface e1/45-48
(CL1)(config-if-range)# no shutdown
(CL1)(config-if-range)# exit
(CL1)(Config)# exit
(CL1)#

  6. Verify that the ISLs are up on the Nexus 5596 switch CL1.

    For more information on Cisco commands, see the appropriate guide in the Cisco Nexus 3000 Series NX-OS Command References.

    Show example

    The following example shows Ports eth1/45 through eth1/48 indicating (P), meaning that the ISL ports are up in the port-channel.

    CL1# show port-channel summary
Flags: D - Down         P - Up in port-channel (members)
       I - Individual   H - Hot-standby (LACP only)
       s - Suspended    r - Module-removed
       S - Switched     R - Routed
       U - Up (port-channel)
       M - Not in use. Min-links not met

                                    Eth1/47(P)   Eth1/48(P)

  7. Verify that interfaces eth1/45-48 already have `channel-group 1 mode active`in their running configuration.

  8. On all nodes, bring up all the cluster interconnect ports connected to the 3232C switch C2:

    network port modify -node node-name -port port-name -up-admin true

    Show example

    The following example shows the specified ports being brought up on nodes n1 and n2:

    cluster::*> network port modify -node n1 -port e0b -up-admin true
cluster::*> network port modify -node n1 -port e0c -up-admin true
cluster::*> network port modify -node n2 -port e0b -up-admin true
cluster::*> network port modify -node n2 -port e0c -up-admin true

  9. On all nodes, revert all of the migrated cluster interconnect LIFs connected to C2:

    network interface revert -vserver Cluster -lif lif-name

    Show example

    The following example shows the migrated cluster LIFs being reverted to their home ports:

    cluster::*> network interface revert -vserver Cluster -lif n1_clus2
cluster::*> network interface revert -vserver Cluster -lif n1_clus3
cluster::*> network interface revert -vserver Cluster -lif n2_clus2
cluster::*> network interface revert -vserver Cluster -lif n2_clus3

  10. Verify all the cluster interconnect ports are now reverted to their home:

    network interface show -role cluster

    Show example

    The following example shows that the LIFs on clus2 reverted to their home ports and shows that the LIFs are successfully reverted if the ports in the Current Port column have a status of true in the Is Home column. If the Is Home value is false, the LIF has not been reverted.

    cluster::*> *network interface show -role cluster*

  8. Bring up ISL ports 31 and 32 on C2, the active 3232C switch, by entering the following Cisco command: no shutdown

    For more information on Cisco commands, see the appropriate guide in the Cisco Nexus 3000 Series NX-OS Command References.

    Show example

    The following example shows the Cisco commands switchname configure brought up on the 3232C switch C2:

    C2# configure
C2(config)# interface ethernet 1/31-32
C2(config-if-range)# no shutdown

  9. Verify that the ISL connections are up on the 3232C switch C2.

    For more information on Cisco commands, see the appropriate guide in the Cisco Nexus 3000 Series NX-OS Command References.

    Ports eth1/31 and eth1/32 should indicate (P) meaning that both ISL ports up in the port-channel

  14. Verify the connectivity of the remote cluster interfaces:

ONTAP 9.9.1 and later

You can use the network interface check cluster-connectivity command to start an accessibility check for cluster connectivity and then display the details:

network interface check cluster-connectivity start and network interface check cluster-connectivity show

cluster1::*> network interface check cluster-connectivity start

NOTE: Wait for a number of seconds before running the show command to display the details.

  1. Expand the cluster by adding nodes to the Nexus 3232C cluster switches.

    The following examples show nodes n3 and n4 have 40 GbE cluster ports connected to ports e1/7 and e1/8 respectively on both the Nexus 3232C cluster switches, and both nodes have joined the cluster. The 40 GbE cluster interconnect ports used are e4a and e4e.

    Display the information about the devices in your configuration:
