Prepare for migration from CN1610 switches to 3132Q-V switches

Contributors netapp-yvonneo

Follow these steps to prepare your CN1610 switches for migration to Cisco Nexus 3132Q-V switches.

Steps

  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

       Local  Discovered
Node   Port   Device       Interface   Platform
------ ------ ------------ ----------- ----------
n1     /cdp
        e0a   CL1          0/1         CN1610
        e0b   CL2          0/1         CN1610
        e0c   CL2          0/2         CN1610
        e0d   CL1          0/2         CN1610
n2     /cdp
        e0a   CL1          0/3         CN1610
        e0b   CL2          0/3         CN1610
        e0c   CL2          0/4         CN1610
        e0d   CL1          0/4         CN1610

  3. Determine the administrative or operational status for each cluster interface.

    1. Display the cluster network port attributes:

      network port show

      Show example

      The following example displays the network port attributes on a system:

      cluster::*> network port show -role Cluster

     Serial Number: 01234568
      Is Monitored: true
            Reason:
  Software Version: 1.2.0.7
    Version Source: ISDP

2 entries were displayed.

  4. Set the -auto-revert parameter to false on cluster LIFs clus1 and clus4 on both nodes:

    network interface modify

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

  5. Verify that the appropriate RCF and image are installed on the new 3132Q-V switches as necessary for your requirements, and make any essential site customizations, such as users and passwords, network addresses, and so on.

    You must prepare both switches at this time. If you need to upgrade the RCF and image, follow these steps:

    1. See the Cisco Ethernet Switches page on NetApp Support Site.

    2. Note your switch and the required software versions in the table on that page.

    3. Download the appropriate version of the RCF.

    4. Select CONTINUE on the Description page, accept the license agreement, and then follow the instructions on the Download page to download the RCF.

    5. Download the appropriate version of the image software.

  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
cluster::*> network interface migrate -vserver Cluster -lif n2_clus3 -destination-node  n2  -destination-port  e0d

  7. Verify the cluster's health:

    network interface show

    Show example

    The following example shows the result of the previous network interface migrate command:

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

         Logical    Status      Network         Current  Current  Is
Vserver  Interface  Admin/Oper  Address/Mask    Node     Port     Home

         n1_clus1   up/up       10.10.0.1/24    n1       e0a      true
         n1_clus2   up/up       10.10.0.2/24    n1       e0a      false
         n1_clus3   up/up       10.10.0.3/24    n1       e0d      false
         n1_clus4   up/up       10.10.0.4/24    n1       e0d      true
         n2_clus1   up/up       10.10.0.5/24    n2       e0a      true
         n2_clus2   up/up       10.10.0.6/24    n2       e0a      false
         n2_clus3   up/up       10.10.0.7/24    n2       e0d      false
         n2_clus4   up/up       10.10.0.8/24    n2       e0d      true

8 entries were displayed.

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

    network port modify

    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

  9. 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

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>

cluster::*> cluster ping-cluster -node n1
