OceanStor 5300 V3, 5500 V3, 5600 V3, 5800 V3, and 6800 V3 Storage System V300R003

Routine maintenance activities are the most common activities for the storage device, including powering on or off the storage device, managing users, modifying basic parameters of the storage device, and managing hardware components. This document applies to the system administrators who are responsible for carrying out routine maintenance activities, monitoring the storage device, and rectifying common device faults.

Bonding Ethernet Ports

Bonding Ethernet Ports

This section describes how to bond Ethernet ports on a same controller.

Prerequisites

Ethernet ports that have IP addresses cannot be bound. The IP addresses of the bonded front-end ports need to be cleared before bonding.

Context

  • Port bonding provides more bandwidth and redundancy for links. Although ports are bonded, each host still transmits data through a single port and the total bandwidth can be increased only when there are multiple hosts. Determine whether to bond ports based on site requirements.
  • The port bond mode of a storage system has the following restrictions:

    • On the same controller, a bond port is formed by a maximum of eight Ethernet ports.
    • Only the interface modules with the same port rate (GE or 10GE) can be bonded.
    • The port cannot be bonded across controllers. Non-Ethernet network ports cannot be bonded.
    • SmartIO cards cannot be bonded if they work in cluster or FC mode or run FCoE service in FCoE/iSCSI mode.
    • The MTU value of the SmartIO port must be the same as that of the host.
    • Read-only users are unable to bind Ethernet ports.
    • Each port only allows to be added to one bonded port. It cannot be added to multiple bonded ports.
    • Physical ports are bonded to create a bond port that cannot be added to the port group.
  • After Ethernet ports are bonded, MTU changes to the default value and you must set the link aggregation mode for the ports. On Huawei switches, you must set the ports to work in static LACP mode.

    The link aggregation modes vary with switch manufacturers. If a non-Huawei switch is used, contact technical support of the switch manufacturer for specific link aggregation configurations.

Procedure

  1. Log in to DeviceManager.
  2. Choose System.
  3. Click the controller enclosure where the Ethernet ports reside.
  4. Click to switch to the rear view.
  5. Select an Ethernet port you want to bond and click Bond Port.

    The Bond Port dialog box and the selected port are displayed. The format of the port name is controller enclosure ID.interface module ID.port ID.

  6. Set the bonding name and available ports for the Ethernet port.
    1. In Bond Name, enter a name for the port to be bound.

      The name:

      • Can contain only letters, digits, periods (.), underscores (_), and hyphens (-).
      • Contains 1 to 31 characters.

    2. From the Available Ports list, select the Ethernet ports you want to bond with the current Ethernet port.
    3. Click OK.

      The security alert dialog box is displayed.

  7. Confirm the bonding of the Ethernet ports.
    1. Confirm the information in the dialog box and select I have read and understand the consequences associated with performing this operation..
    2. Click OK.

      If the operation succeeded, the Success message box is displayed.

    3. Click OK.
