(Optional) Changing IP Addresses of Management Network Ports Using DeviceManager
If the IP address of the management network port has been configured on the storage device through the serial port, skip this step.
Prerequisites
The temporary maintenance terminal used for initial configuration has been connected to the storage device's management port, and the maintenance terminal IP address and management port's default IP address are on the same network segment.
Context
- The default IP address of network port 0 on management module 0 is 192.168.128.101 and that of network port 0 on management module 1 is 192.168.128.102. The default subnet mask is 255.255.0.0.
- For a 4 U controller enclosure, the default internal heartbeat IP addresses are 127.127.127.10, 127.127.127.11, 127.127.127.12, and 127.127.127.13, and the subnet mask is 255.255.255.0.
- The default IP address of the maintenance network port is 172.31.128.101 or 172.31.128.102, and the default subnet mask is 255.255.0.0.
Precautions
- After the IP addresses of the management network ports are modified, communication between the maintenance terminal and the storage device will be lost. Therefore, you are advised to first modify the IP addresses of controllers' management network 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. Otherwise, route conflicts may occur. The default internal heartbeat IP addresses are 127.127.127.10, 127.127.127.11, 127.127.127.12, and 127.127.127.13, and the subnet mask is 255.255.255.0. Therefore, you cannot use IP addresses that belong to the 127.127.127.XXX network segment.
- Heartbeats are packets transmitted between two devices for them to judge the availability of the peer device. Heartbeats do not require acknowledgement. They are usually used for node communication, fault diagnosis, and event triggering in an HA system.
- 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 are configured before delivery, and cannot be modified.
- When multiple controller enclosures are deployed, the default internal heartbeat IP addresses of each controller enclosure are the same as those when a single controller enclosure is deployed.
- The IP addresses of 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 connect only 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
- Log in to DeviceManager.
- In the navigation pane on the right, click
.
- Click the controller enclosure where the management network port to be modified resides.
- Click
to switch to the rear view.
- Click the management network port to be modified.
After the IP addresses of the management network ports are modified, communication between the maintenance terminal and the storage device will be lost. Therefore, you are advised to first modify the IP addresses of controllers' management network ports that are not directly connected to the maintenance terminal.
The Manage Port dialog box is displayed.
- Change the IP addresses of management network ports.
- Click Modify.
- In IPv4 Address or IPv6 Address, enter the IP address of the management network port.
- In Subnet Mask or Prefix, enter the subnet mask or prefix of the management IP address.
- In IPv4 Gateway or IPv6 Gateway, enter the gateway of the management IP address.
- Confirm IP address modification.
- Click Apply.
The security alert dialog box is displayed.
- Confirm the information in the dialog box and select I have read and understand the consequences associated with performing this operation.
- Click OK.
The Success dialog box is displayed, indicating that the operation succeeded.
- Click OK.
- Click Apply.
- Repeat 3 to 7 to change the IP addresses of other management network ports.
