Replace a Cisco Nexus 3232C cluster switch

Contributors netapp-yvonneo netapp-jolieg netapp-jsnyder

Follow these steps to replace a defective Cisco Nexus 3232C switch in a cluster. This is a non-disruptive procedure.

Review requirements

What you'll need

Make sure that the existing cluster and network configuration has the following characteristics:

  • The Nexus 3232C cluster infrastructure are redundant and fully functional on both switches.

    The Cisco Ethernet Switches page has the latest RCF and NX-OS versions on your switches.

  • All cluster ports must be in the up state.

  • Management connectivity must exist on both switches.

  • All cluster logical interfaces (LIFs) are in the up state and are not migrated.

The replacement Cisco Nexus 3232C switch has the following characteristics:

  • Management network connectivity is functional.

  • Console access to the replacement switch is in place.

  • The appropriate RCF and NX-OS operating system image is loaded onto the switch.

  • Initial customization of the switch is complete.

For more information

See the following:

Replace the switch

About this task

This replacement procedure describes the following scenario:

  • The cluster initially has four nodes connected to two Nexus 3232C cluster switches, CL1 and CL2.

  • You plan to replace cluster switch CL2 with C2 (steps 1 to 21):

    • On each node, you migrate the cluster LIFs connected to cluster switch CL2 to cluster ports connected to cluster switch CL1.

    • You disconnect the cabling from all ports on cluster switch CL2 and reconnect the cabling to the same ports on the replacement cluster switch C2.

    • You revert the migrated cluster LIFs on each node.

About the examples

This replacement procedure replaces the second Nexus 3232C cluster switch CL2 with the new 3232C switch C2.

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

  • The four nodes are n1, n2, n3, and n4.

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

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

  • n1_clus3 is the second LIF connected to cluster switch C2 for node n1.-

  • n1_clus4 is the second LIF connected to cluster switch CL1, for node n1.

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.

The examples in this replacement procedure use four nodes. Two of the nodes use four 10 GB cluster interconnect ports: e0a, e0b, e0c, and e0d. The other two nodes use two 40 GB cluster interconnect ports: e4a and e4e. See the Hardware Universe to verify the correct cluster ports for your platform.

Step 1: Display and migrate the cluster ports to switch

  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:

Step 2: Migrate ISLs to switch CL1 and C2

  1. Shut down the ports 1/31 and 1/32 on cluster switch CL1.

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

    Show example 
    (CL1)# configure
(CL1)(Config)# interface e1/31-32
(CL1)(config-if-range)# shutdown
(CL1)(config-if-range)# exit
(CL1)(Config)# exit
(CL1)#

  2. Remove all the cables attached to the cluster switch CL2 and reconnect them to the replacement switch C2 for all the nodes.

  3. Remove the inter-switch link (ISL) cables from ports e1/31 and e1/32 on cluster switch CL2 and reconnect them to the same ports on the replacement switch C2.

  4. Bring up ISL ports 1/31 and 1/32 on the cluster switch CL1.

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

    Show example 
    (CL1)# configure
(CL1)(Config)# interface e1/31-32
(CL1)(config-if-range)# no shutdown
(CL1)(config-if-range)# exit
(CL1)(Config)# exit

  5. Verify that the ISLs are up on CL1.

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

    Ports Eth1/31 and Eth1/32 should indicate (P), which means that the ISL ports are up in the port-channel:

    Show example 
    CL1# show port-channel summary
Flags: D - Down         P - Up in port-channel (members)

  6. Verify that the ISLs are up on cluster switch C2.

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

    Show example

    Ports Eth1/31 and Eth1/32 should indicate (P), which means that both ISL ports are up in the port-channel.

    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

  7. On all nodes, bring up all the cluster interconnect ports connected to the replacement switch C2:

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

    Show example 
    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
cluster::*> network port modify -node n3 -port e4e -up-admin true
cluster::*> network port modify -node n4 -port e4e -up-admin true

Step 3: Revert all LIFs to originally assigned ports

  1. Revert all the migrated cluster interconnect LIFs on all the nodes:

    network interface revert -vserver cluster -lif lif-name

    Show example

    You must revert all the cluster interconnect LIFs individually as shown in the following 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
Cluster::*> network interface revert -vserver cluster -lif n3_clus2
Cluster::*> network interface revert -vserver cluster -lif n4_clus2

  2. Verify that the cluster interconnect ports are now reverted to their home:

    network interface show

    Show example

    The following example shows that all the LIFs have been successfully reverted because the ports listed under the Current Port column have a status of true in the Is Home column. If a port has a value of false, the LIF has not been reverted.

    cluster::*> network interface show -role cluster

  2. Delete the replaced cluster switch CL2 if it has not been removed automatically:

    system cluster-switch delete -device cluster-switch-name

  3. Verify that the proper cluster switches are monitored:

    system cluster-switch show

    Show example

    The following example shows the cluster switches are monitored because the Is Monitored state is true.

    cluster::> system cluster-switch show

  4. Enable the cluster switch health monitor log collection feature for collecting switch-related log files:

    system cluster-switch log setup-password

    system cluster-switch log enable-collection

    Show example 
    cluster::*> system cluster-switch log setup-password
Enter the switch name: <return>
The switch name entered is not recognized.
Choose from the following list:
CL1
C2

cluster::*> system cluster-switch log setup-password

Enter the switch name: CL1
RSA key fingerprint is e5:8b:c6:dc:e2:18:18:09:36:63:d9:63:dd:03:d9:cc
Do you want to continue? {y|n}::[n] y

Enter the password: <enter switch password>
Enter the password again: <enter switch password>

cluster::*> system cluster-switch log setup-password

Enter the switch name: C2
RSA key fingerprint is 57:49:86:a1:b9:80:6a:61:9a:86:8e:3c:e3:b7:1f:b1
Do you want to continue? {y|n}: [n] y

Enter the password: <enter switch password>
Enter the password again: <enter switch password>

cluster::*> system cluster-switch log enable-collection

Do you want to enable cluster log collection for all nodes in the cluster?
{y|n}: [n] y
