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.

Modifying an Ethernet Port

Modifying an Ethernet Port

When the networking mode between a storage device and an application server changes, modify the settings of Ethernet port parameters to ensure proper communication between them.

Precautions

  • Ensure that the storage device has redundant connections or that services running on the storage device are stopped. Change the IP address of the Ethernet port only when necessary.
  • The IP addresses of the Ethernet port and internal heartbeat must be on different network segments.

    The default IP addresses of the internal heartbeat on the dual-controller storage system are 127.127.127.10 and 127.127.127.11, and those of the internal heartbeat on the four-controller storage system are 127.127.127.10, 127.127.127.11, 127.127.127.12, and 127.127.127.13.

  • Internal heartbeat links are established between controllers for the controllers to detect each other's working status. Heartbeat links do not require separate cable connections. In addition, internal heartbeat IP addresses have been assigned before delivery and cannot be changed.
  • The IP address of an Ethernet port cannot be in the same network segment as that of a management network port.
  • The IP address of an Ethernet port cannot be in the same network segment as that of a maintenance network port. The default IP address of the maintenance network port must fall within the 172.31.XXX.XXX segment.
  • If an Ethernet port connects to an application server, the IP address of the Ethernet port must be in the same network segment as that of the service network port on the application server. If an Ethernet port connects to another storage device, the IP address of the Ethernet port must be in the same network segment as that of the peer Ethernet port on the other storage device. If available IP address become insufficient for a network segment for which you want to add an IP address, manually add routes.
  • After an Ethernet port is bound, its properties cannot be modified.

Procedure

  1. Log in to DeviceManager.
  2. Choose System.
  3. Select the controller enclosure where the Ethernet port resides.
  4. Click to switch to the rear view.
  5. Click the Ethernet port whose information you want to modify.

    The Ethernet Port dialog box is displayed.

  6. Modify the Ethernet port.
    1. Click Modify.

      NOTE:
      You can also click Properties to modify the parameters of the Ethernet port.


    2. In the IPv4 address or IPv6 address text box, enter an IP address for the Ethernet port.
    3. In the Subnet Mask or Prefix text box, enter the subnet mask or prefix of the Ethernet port.
    4. In MTU (Byte), type a maximum transfer unit (MTU) for the packets transmitted between the Ethernet port and the application server.
  7. Confirm the Ethernet port modification.
    1. Click Apply.

      The security alert dialog box is displayed.

    2. Confirm the information in the dialog box and select I have read and understand the consequences associated with performing this operation..
    3. Click OK.

      The Success dialog box is displayed, indicating that the operation succeeded.

    4. Click OK.
