Modifying an Ethernet Port

Precautions

• Change the IP address of an Ethernet port only when necessary. Before changing the IP address of an Ethernet port, ensure that redundant connections are available or stop services carried by this port.
• The IP addresses of an Ethernet port and internal heartbeat must be on different network segments.

  The default IP addresses of internal heartbeat on a dual-controller storage system are 127.127.127.10 and 127.127.127.11, and those of internal heartbeat on a 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 enable the controllers to detect each other's working status. Heartbeat links do not require separate cable connections. The internal heartbeat IP addresses are 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 addresses become insufficient for a network segment for which you want to add an IP address, manually add routes.
• After Ethernet ports are bonded, their properties cannot be modified.

Procedure

1. Log in to DeviceManager.
2. Choose System.
3. Click 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.

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

   2. Specify IPv4 Address or IPv6 Address.
   3. Specify Subnet Mask or Prefix.
   4. Specify MTU (Byte).

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.
