Configuring Port IP Addresses

Configure Ethernet port parameters to ensure proper communication between the storage system and application server.

Note the following items when setting the properties of an Ethernet port:

  • The default internal heartbeat IP addresses of a dual-controller storage system are 127.127.127.10 and 127.127.127.11, and those of a four-controller storage system are 127.127.127.10, 127.127.127.11, 127.127.127.12, and 127.127.127.13. Therefore, the IP address of the Ethernet port must not be in the 127.127.127.XXX segment and the gateway address must not be 127.127.127.10, 127.127.127.11, 127.127.127.12, or 127.127.127.13. Otherwise, routing will fail. 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 address of the Ethernet port cannot be in the same network segment as that of a management network port.
  • The IP address of the Ethernet port cannot be in the same network segment as that of a maintenance network port.
  • If the 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 the 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 Ethernet port on the other storage device. Add routes if available IP addresses in the desired segment are insufficient.

To configure an IP address for an Ethernet port, perform the following steps:

  1. Go to the Ethernet Port dialog box.

    1. On the DeviceManager home page, click System.
    2. In the middle function pane, click the cabinet whose Ethernet ports you want to view.
    3. Click the controller enclosure where the desired Ethernet ports reside. The controller enclosure view is displayed.
    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. Click Modify.

  2. Modify the Ethernet port, as shown in Figure 5-23.

    1. In IPv4 Address or IPv6 Address, enter an IP address for the Ethernet port.
    2. In Subnet Mask or Prefix, enter a subnet mask or prefix for the Ethernet port.
    3. In MTU (Byte), enter the maximum size of data packet that can be transferred between the Ethernet port and the host. The value is an integer ranging from 1500 to 9216.
    Figure 5-23 Configuring an IP address

  3. Confirm the Ethernet port modification.

    1. Click Apply.

      The Danger 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 is successful.

    4. Click OK.

(Optional) Adding Routes

If iSCSI networking is used and data needs to be transmitted across network segments, perform the following operations to configure routes:

  1. Log in to DeviceManager.
  2. Choose Provisioning > Port > Ethernet Ports.
  3. Select the Ethernet port for which you want to add a route and click Route Management.

    The Route Management dialog box is displayed.

  4. Configure the route information for the Ethernet port.

    1. In IP Address, select the IP address of the Ethernet port.
    2. Click Add.

      The Add Route dialog box is displayed.

    3. In Type, select the type of the route to be added.

      There are three route options:

      • Default route

        Data is forwarded through this route by default if no preferred route is available. The destination address field and the target mask field (IPv4) or prefix (IPv6) of the default route are automatically set to 0. To use this option, you only need to add a gateway.

      • Host route

        A route to an individual host. The destination mask (IPv4: 255.255.255.255) or prefix (IPv6: 128) of the host route is automatically set. To use this option, add the destination address and a gateway.

      • Network segment route

        A route to a network segment. You need to add the destination address, destination address mask (IPv4) or prefix (IPv6), and gateway. For example, the destination address is 172.17.0.0, destination address mask is 255.255.0.0, and gateway is 172.16.0.1.

    4. Set Destination Address.

      Set Destination Address to the IPv4 or IPv6 (depending on which one you use) address or network segment of the application server's service network port or that of the other storage system's Ethernet port.

    5. Set Destination Mask (IPv4) or Prefix (IPv6).
      • If an IPv4 address is used, this parameter specifies the subnet mask of the IP address for the service network port on the application server or the other storage device.
      • If an IPv6 address is used, this parameter specifies the prefix of the IPv6 address for the application server's service network port or that of the other storage system's Ethernet port.
    6. In Gateway, enter the gateway of the local storage system's Ethernet port IP address.

  5. Click OK. The route information is added to the route list.

    A security alert dialog box is displayed.

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

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

    NOTE:

    To remove a route, select it and click Remove.

  8. Click Close.

Adding an Initiator to a Host

This section details how to add initiators to the hosts on the storage system. For other storage configurations, see the Basic Storage Service Configuration Guide corresponding to your storage system.

  1. Log in to DeviceManager.
  2. Choose Provisioning > Host.
  3. Select the target host and click Add Initiator.

    Figure 5-24 Selecting a host

  4. Select the initiator and click to add it to Selected Initiators.

    Figure 5-25 Adding an initiator

  5. Click OK.

    The initiator properties depend on the operating system and multipathing software used by the hosts. For details, see the storage-side configuration in the multipathing configuration section.
