Managing Routes (for IP Replication Links)

Prerequisites

IP addresses have been configured for Ethernet ports.

On a redundant network, IP addresses and routes must be configured for multiple Ethernet ports.

Context

Perform this operation on both storage systems.

Procedure

1. Choose System > Hardware.
2. In the navigation tree, select a physical port for which you want to create a logical port.
3. In the function pane, select Manage Logical Port.

   The Manage Logical Port dialog box is displayed.

4. In the Manage Logical Port dialog box, select a logical port.
5. Click Manage Route.
6. Set the route information for the Ethernet port.
   1. In the Manage Route dialog box, click Add.

      The default IP addresses of the internal heartbeats on a dual-controller storage system are 127.127.127.10 and 127.127.127.11, and the default IP addresses of the internal heartbeats on 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 a router cannot be in the 127.127.127.XXX segment. Additionally, the IP address of the gateway cannot 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 product delivery, and you cannot change these IP addresses).

   2. 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 destination 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 connecting 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, you only need to add the destination address and a gateway.

      • Network segment route

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

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

7. Click to add the route information to the route list.

   The Danger dialog box is displayed.

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

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

   To remove a route, select it and click .

10. Click Close.
