OceanStor 2800 V5 V500R007

This document is applicable to OceanStor 2800 V5. 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 is intended for the system administrators who are responsible for carrying out routine maintenance activities, monitoring the storage device, and rectifying common device faults.

Changing IP Addresses of Management Network Ports

Changing IP Addresses of Management Network Ports

This section describes how to access a storage system through the IP addresses of the management network ports to configure and manage the storage system.

Prerequisites

Ensure that the temporary maintenance terminal used for initial configuration has been connected to the management ports of the storage device, and the IP address of the maintenance terminal and the default IP address of the management port are on the same network segment.

Context

  • The default internal heartbeat IP addresses are 127.127.127.10 and 127.127.127.11 for a dual-controller storage system, and the subnet mask is 255.255.255.0. The default internal heartbeat IP addresses are 127.127.127.10, 127.127.127.11, 127.127.127.12, and 127.127.127.13 for a four-controller storage system, and the subnet mask is 255.255.255.0.
  • The default IP addresses of maintenance network ports are 172.31.128.101 and 172.31.128.102, and the subnet mask is 255.255.0.0.

Precaution

  • After the IP addresses of the management ports are modified, communication between the maintenance terminal and the storage device is down. Therefore, you are advised to first modify the IP addresses of controllers' management ports that are not directly connected to the maintenance terminal.
  • The IP addresses of management network ports and internal heartbeat IP addresses must be on different network segments. For a dual-controller system, you cannot use IP addresses that belong to the 127.127.127.XXX network segment. For a four-controller storage system, you cannot set IP addresses that belong to the 127.127.127.XXX, 172.16.126.XXX, 172.16.127.XXX, and 172.16.128.XXX network segments.
NOTE:
  • Heartbeats are the packets, requiring no acknowledgement, transmitted between two devices. The device can judge the validity status of the peer device. Heartbeat supports node communication, fault diagnosis, and event triggering.
  • Internal heartbeat links are established between controllers for these controllers to detect each other's working status. You do not need to separately connect cables. In addition, internal heartbeat IP addresses have been assigned before delivery, and you cannot change these IP addresses.
  • The IP addresses of both management network ports and those of maintenance network ports must be on different network segments. You cannot use IP addresses that belong to the 172.31.XXX.XXX. Otherwise, route conflicts may occur. You are advised to only connect the management network port to the network.
  • By default, IP addresses of the management network ports and those of the service network ports are on different network segments. If they are in the same network segment, some functions of the storage system may be unavailable. It is strongly recommended that you do not set them on the same network segment.

Procedure

  1. Modify the IP address of the temporary maintenance terminal used for initial configuration to the 192.168.XXX.XXX network segment.
  2. Log in to DeviceManager.
  3. On the right navigation bar, click .
  4. Click the controller enclosure where the management port resides.
  5. Click to switch to the rear view.
  6. Click the management port whose information you want to view.

    After the IP addresses of the management ports are modified, communication between the maintenance terminal and the storage device is down. Therefore, you are advised to first modify the IP addresses of controllers' management ports that are not directly connected to the maintenance terminal.

    The Management Port dialog box is displayed.

  7. Modify the IP address of management network port.

    1. Click Modify.
    2. In the IPv4 Address or IPv6 Address text box, enter an IP address for the management network port.
    3. In the Subnet Mask or Prefix area, enter the subnet mask or prefix of the management network port.
    4. In the IPv4 Gateway or IPv6 Gateway text box, enter a gateway of the IP address for the management network port.

  8. Confirm the IP address of management network 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 understood the consequences associated with performing this operation.
    3. Click OK.

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

    4. Click OK.

  9. Perform 4 to 8 again to modify other management port IP addresses.
