Managing Routes

Managing Routes

If cross-segment data transmission is required in an iSCSI network, this operation guides you to configure routes, enabling cross-segment data transmission.

Prerequisites

The IP address of an iSCSI host port has been configured.The IP address of an Ethernet port has been configured.
NOTE:
In redundant links, you must configure IP addresses and route for multiple Ethernet ports.

Procedure

  1. Go to the Route Management dialog box.
    1. On the right navigation bar, click .
    2. In the Basic Information area of the function pane, click the device icon.
    3. In the right function pane, click the cabinet whose Ethernet ports you want to view.
    4. Click the controller enclosure where the Ethernet ports reside.

      The system displays the front view of the controller enclosure.

    5. Click to switch to the rear view.
    6. Click the Ethernet port to which you want to add a route.
    7. Click Route Management.

      The Route Management dialog box is displayed.

  2. Set 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.

      The default IP addresses of the internal heartbeat on the system are 127.127.127.1X. Therefore, the IP address of the router cannot fall within the 127.127.127.XXX segment. Besides, the IP address of the gateway cannot be 127.127.127.1X. 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).

    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 target 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

        The host route is the route to an individual host. The target mask (IPv4) or prefix (IPv6) of the host route are automatically set respectively to 255.255.255.255 or 128. To use this option, you only need to add the target address and a gateway.

      • Network segment route

        The network segment route is the route to a network segment. You need to add the target address, target mask (IPv4) or prefix (IPv6), and gateway.

    4. Add Destination address.

      • If IP address is an IPv4 address, set Destination address to the IPv4 address or network segment of the application server's service network port or the IPv4 address or network segment of the storage device's Ethernet port.
      • If IP address is an IPv6 address, set Destination address to the IPv6 address or network segment of the application server's service network port or the IPv6 address or network segment of the storage device's Ethernet port.

    5. Add Destination mask (IPv4) or Prefix (IPv6).

      • Add Destination mask for an IPv4 address. This parameter specifies the subnet mask of the IP address for the service network port on the application server or on the storage device that connects to the Ethernet port.
      • Add Prefix for an IPv6 address. This parameter specifies the prefix to the IPv6 address of the host's service network port or the prefix to the IPv6 address of the storage device's Ethernet port.

    6. In Gateway, enter the gateway where the local end Ethernet port's IP address resides.
  3. Click OK. The route information is added to the route list.

    The security alert dialog box is displayed.

  4. Confirm the information in the dialog box and select I have read and understood the consequences associated with performing this operation.
  5. Click OK.

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

    NOTE:

    To delete a route, select it and click Remove.

  6. Click Close.
