Migrating to a switched NetApp cluster environment using Broadcom-supported BES-53248 cluster switches

If you have an existing two-node switchless cluster environment, you can migrate to a two-node switched cluster environment using Broadcom-supported BES-53248 cluster switches to enable you to scale beyond two nodes in the cluster.

Before you begin

Two-node switchless configuration:

Broadcom-supported BES-53248 cluster switch configuration:

About this task

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

Steps

  1. Change the privilege level to advanced, entering y when prompted to continue: set -privilege advanced
    The advanced prompt (*>) appears.
  2. 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
    where 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.
    Example

    The following command suppresses automatic case creation for two hours:

    cluster1::*> system node autosupport invoke -node * -type all -message MAINT=2h
  3. Disable all node-facing ports (not ISL ports) on both the new cluster switches cs1 and cs2.
    Note: You must not disable the ISL ports.
    Example

    The following example shows that node-facing ports 1 through 16 are disabled on switch cs1:

    (cs1)# configure 
    (cs1)(Config)#   interface 0/1-0/16 
    (cs1)(Interface 0/1-0/16)# shutdown
    (cs1)(Interface 0/1-0/16)# exit
    (cs1)(Config)# exit
  4. Verify that the ISL and the physical ports on the ISL between the two BES-53248 switches cs1 and cs2 are up: show port-channel
    Example

    The following example shows that the ISL ports are up on switch cs1:

    (cs1)# show port-channel 1/1
    Local Interface................................ 1/1
    Channel Name................................... Cluster-ISL
    Link State..................................... Up
    Admin Mode..................................... Enabled
    Type........................................... Dynamic
    Port channel Min-links......................... 1
    Load Balance Option............................ 7
    (Enhanced hashing mode)
    
    Mbr    Device/       Port       Port
    Ports  Timeout       Speed      Active
    ------ ------------- ---------  -------
    0/55   actor/long    100G Full  True
           partner/long
    0/56   actor/long    100G Full  True
           partner/long
    (cs1) #
    

    The following example shows that the ISL ports are up on switch cs2 :

    (cs2)# show port-channel 1/1
    Local Interface................................ 1/1
    Channel Name................................... Cluster-ISL
    Link State..................................... Up
    Admin Mode..................................... Enabled
    Type........................................... Dynamic
    Port channel Min-links......................... 1
    Load Balance Option............................ 7
    (Enhanced hashing mode)
    
    Mbr    Device/       Port       Port
    Ports  Timeout       Speed      Active
    ------ ------------- ---------  -------
    0/55   actor/long    100G Full  True
           partner/long
    0/56   actor/long    100G Full  True
           partner/long
    (cs2) #
    
  5. Display the list of neighboring devices: show isdp neighbors
    This command provides information about the devices that are connected to the system.
    Example

    The following example lists the neighboring devices on switch cs1:

    (cs1)# show isdp neighbors
    
    Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge,
                      S - Switch, H - Host, I - IGMP, r - Repeater
    Device ID      Intf     Holdtime  Capability   Platform    Port ID
    -------------- -------- --------- ------------ ----------- ---------
    cs2            0/55     176       R            BES-53248   0/55
    cs2            0/56     176       R            BES-53248   0/56
    
    

    The following example lists the neighboring devices on switch cs2:

    (cs2)# show isdp neighbors 
    
    Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge,
                      S - Switch, H - Host, I - IGMP, r - Repeater
    Device ID      Intf     Holdtime  Capability   Platform    Port ID
    -------------- -------- --------- ------------ ----------- ---------
    cs2            0/55     176       R            BES-53248   0/55
    cs2            0/56     176       R            BES-53248   0/56
    
    
  6. Verify that all cluster ports are up: network port show -ipspace Cluster

    Example
    cluster1::*> system node autosupport invoke -node * -type all -message MAINT=END
  25. Change the privilege level back to admin: set -privilege admin
