Migrate from CN1610 cluster switches to Cisco Nexus 3132Q-V cluster switches

Contributors netapp-jolieg

Follow this procedure to replace the existing CN1610 cluster switches with Cisco Nexus 3132Q-V cluster switches.

Review requirements

Review the NetApp CN1610 requirements requirements in Requirements for replacing Cisco Nexus 3132Q-V cluster switches.

For more information, see:

Replace the switch

Switch and node nomenclature

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

  • The command outputs might vary depending on different releases of ONTAP software.

  • The CN1610 switches to be replaced are CL1 and CL2.

  • The Nexus 3132Q-V switches to replace the CN1610 switches are C1 and C2.

  • n1_clus1 is the first cluster logical interface (LIF) that is connected to cluster switch 1 (CL1 or C1) for node n1.

  • n1_clus2 is the first cluster LIF that is connected to cluster switch 2 (CL2 or C2) for node n1.

  • n1_clus3 is the second LIF that is connected to cluster switch 2 (CL2 or C2) for node n1.

  • n1_clus4 is the second LIF that is connected to cluster switch 1 (CL1 or C1) for node n1.

  • The nodes are n1, n2, n3, and n4.

  • 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.

About the examples

The examples in this procedure use four nodes:

  • Two nodes use four 10 GbE cluster interconnect ports: e0a, e0b, e0c, and e0d.

  • The other two nodes use two 40/100 GbE cluster interconnect fiber cables: e4a and e4e.

The Hardware Universe has information about the cluster fiber cables on your platforms.

About this task

This procedure covers the following scenario:

  • The cluster starts with two nodes connected to two CN1610 cluster switches.

  • Cluster switch CL2 to be replaced by C2

    • Traffic on all cluster ports and LIFs on all nodes connected to CL2 are migrated onto the first cluster ports and LIFs connected to CL1.

    • Disconnect cabling from all cluster ports on all nodes connected to CL2, and then use supported breakout cabling to reconnect the ports to new cluster switch C2.

    • Disconnect cabling between ISL ports CL1 and CL2, and then use supported breakout cabling to reconnect the ports from CL1 to C2.

    • Traffic on all cluster ports and LIFs connected to C2 on all nodes is reverted.

  • Cluster switch CL1 to be replaced by C1

    • Traffic on all cluster ports and LIFs on all nodes connected to CL1 are migrated onto the second cluster ports and LIFs connected to C2.

    • Disconnect cabling from all cluster ports on all nodes connected to CL1, and then use supported breakout cabling to reconnect the ports to new cluster switch C1.

    • Disconnect cabling between ISL ports CL1 and C2, and then use supported breakout cabling to reconnect the ports from C1 to C2.

    • Traffic on all migrated cluster ports and LIFs connected to C1 on all nodes is reverted.

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

Step 1: Prepare for replacement

  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=xh

    x is the duration of the maintenance window in hours.

    Note The AutoSupport message notifies technical support of this maintenance task so that automatic case creation is suppressed during the maintenance window.

  2. Display information about the devices in your configuration:

    network device-discovery show

    Show example

    The following example displays how many cluster interconnect interfaces have been configured in each node for each cluster interconnect switch:

    cluster::> network device-discovery show

  6. Migrate the LIFs associated with the second CN1610 switch to be replaced:

    network interface migrate

    Note

    You must migrate the cluster LIFs from a connection to the node, either through the service processor or node management interface, which owns the cluster LIF being migrated.
    Show example

    The following example shows n1 and n2, but LIF migration must be done on all the nodes:

    cluster::*> network interface migrate -vserver Cluster -lif n1_clus2 -destination-node  n1  -destination-port  e0a
cluster::*> network interface migrate -vserver Cluster -lif n1_clus3 -destination-node  n1  -destination-port  e0d
cluster::*> network interface migrate -vserver Cluster -lif n2_clus2 -destination-node  n2  -destination-port  e0a

  10. Shut down the ISL ports 13 through 16 on the active CN1610 switch CL1:

    shutdown

    Show example

    The following example shows how to shut down ISL ports 13 through 16 on the CN1610 switch CL1:

    (CL1)# configure
(CL1)(Config)# interface 0/13-0/16
(CL1)(Interface 0/13-0/16)# shutdown
(CL1)(Interface 0/13-0/16)# exit
(CL1)(Config)# exit
(CL1)#

  11. Build a temporary ISL between CL1 and C2:

    Show example

    The following example builds a temporary ISL between CL1 (ports 13-16) and C2 (ports e1/24/1-4):

    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

Step 2: Configure ports

  1. On all nodes, remove the cables that are attached to the CN1610 switch CL2.

    With supported cabling, you must reconnect the disconnected ports on all of the nodes to the Nexus 3132Q-V switch C2.

  2. Remove four ISL cables from ports 13 to 16 on the CN1610 switch CL1.

    You must attach appropriate Cisco QSFP to SFP+ breakout cables connecting port 1/24 on the new Cisco 3132Q-V switch C2, to ports 13 to 16 on existing CN1610 switch CL1.

    Note When reconnecting any cables to the new Cisco 3132Q-V switch, you must use either optical fiber or Cisco twinax cables.

  3. To make the ISL dynamic, configure the ISL interface 3/1 on the active CN1610 switch to disable the static mode: no port-channel static

    This configuration matches with the ISL configuration on the 3132Q-V switch C2 when the ISLs are brought up on both switches in step 11

    Show example

    The following example shows the configuration of the ISL interface 3/1 using the no port-channel static command to make the ISL dynamic:

    (CL1)# configure
(CL1)(Config)# interface 3/1
(CL1)(Interface 3/1)# no port-channel static
(CL1)(Interface 3/1)# exit
(CL1)(Config)# exit
(CL1)#

  4. Bring up ISLs 13 through 16 on the active CN1610 switch CL1.

    Show example

    The following example illustrates the process of bringing up ISL ports 13 through 16 on the port-channel interface 3/1:

    (CL1)# configure
(CL1)(Config)# interface 0/13-0/16,3/1
(CL1)(Interface 0/13-0/16,3/1)# no shutdown
(CL1)(Interface 0/13-0/16,3/1)# exit
(CL1)(Config)# exit
(CL1)#

  5. Verify that the ISLs are up on the CN1610 switch CL1:

    show port-channel

    The "Link State" should be Up, "Type" should be Dynamic, and the "Port Active" column should be True for ports 0/13 to 0/16:

    Show example 
    (CL1)# show port-channel 3/1
Local Interface................................ 3/1
Channel Name................................... ISL-LAG
Link State..................................... Up
Admin Mode..................................... Enabled
Type........................................... Dynamic
Load Balance Option............................ 7

       partner/long

  6. Verify that the ISLs are up on the 3132Q-V switch C2:

    show port-channel summary

    Show example

    Ports Eth1/24/1 through Eth1/24/4 should indicate (P), meaning that all four ISL ports are up in the port-channel. Eth1/31 and Eth1/32 should indicate (D) as they are not connected:

    C2# 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

                                     Eth1/24/4(P)

  7. Bring up all of the cluster interconnect ports that are connected to the 3132Q-V switch C2 on all of the nodes:

    network port modify

    Show example

    The following example shows how to bring up the cluster interconnect ports connected to the 3132Q-V switch C2:

    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

  8. Revert all of the migrated cluster interconnect LIFs that are connected to C2 on all of the nodes:

    network interface revert

    Show example 
    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

  9. Verify that all of the cluster interconnect ports are reverted to their home ports:

    network interface show

    Show example

    The following example shows that the LIFs on clus2 are 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, then the LIF is not reverted.

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

  9. Remove the replaced CN1610 switches if they are not automatically removed:

    system cluster-switch delete

    Show example

    The following example shows how to remove the CN1610 switches:

    cluster::> system cluster-switch delete -device CL1
cluster::> system cluster-switch delete -device CL2

  10. Configure clusters clus1 and clus4 to -auto-revert on each node and confirm:

    Show example 
    cluster::*> network interface modify -vserver node1 -lif clus1 -auto-revert true
cluster::*> network interface modify -vserver node1 -lif clus4 -auto-revert true
cluster::*> network interface modify -vserver node2 -lif clus1 -auto-revert true
cluster::*> network interface modify -vserver node2 -lif clus4 -auto-revert true

  11. Verify that the proper cluster switches are monitored:

    system cluster-switch show
