     1. Click Manually Add Node.

        The Add Node page is displayed on the right.

     2. Configure basic node and authentication information. Table 1 describes related parameters.

        Table 1 Basic and authentication parameters of a node

        Parameter	Description
        Management IP Address	Indicates the management IP address of the node.
        Cabinet	Indicates the cabinet where the node resides.
        Chassis	Indicates the chassis where the node resides.
        Slot	Indicates the slot number where the node resides.
        Node Model	Indicates the physical model of the node.
        Node Name	Indicates the name of the node.
        Username	If you use the pre-installed OS, enter fsadmin for authentication. Its default password is IaaS@OS-CLOUD9!. If you use a third-party operating system: User root is preferentially used for authentication. If you use a non-root user for authentication, the user must have the SUDO, remote SFTP, and SSH permissions. For the SUDO permission, when running the sudo su - root command, you must use the password of user root instead of the password of this user.
        Password	Indicates the password of the logged-in user.
        Password of root	When the user is a non-root user, enter the password of user root.

     3. Click OK.
     4. Add other storage nodes in sequence and click Submit.
     5. After the nodes are configured successfully, click Next.

4. Configure storage networks.
   

   • If a front- and back-end shared network is deployed during initialization, you can only deploy the shared network. If front- and back-end separated networks are deployed during initialization, you can only deploy separated networks.
   • Front- and back-end shared network
     1. Configure the front- and back-end shared network. Table 2 describes related parameters.

        Table 2 Front- and back-end shared network parameters

        Parameter	Description
        Use Configured IP Address Only	If you select Yes, the system only allocates configured storage IP addresses in the specified IP address range to the nodes.
        Transmission Protocol	Indicates the transmission protocol used by the network. Possible options are TCP, IB, and RoCE.
        Bond Mode	Indicates the bond mode of the storage network. bond1: active/standby mode bond4: dynamic link aggregation mode NOTE: When Transmission Protocol is set to TCP, bond1 and bond4 are supported. You are advised to select bond4. When Transmission Protocol is set to IB, only bond1 is supported. In this case, bond1 supports the load balancing function. When Transmission Protocol is set to RoCE, bond1 and bond4 are supported. You are advised to select bond4.
        IP Address Range	Indicates the IP address segment of the storage network. NOTE: The IP addresses in the specified IP address range cannot be in the same network segment as those of other ports on the node. In the event of using an IPv4 address: A 32-bit IPv4 address is divided into four 8-bit fields that are expressed in dotted decimal notation. Each field of the IPv4 address cannot be left empty and must be an integer. The value of the leftmost field ranges from 1 to 223 (excluding 127). The values of the other fields range from 0 to 255. An IPv4 address cannot be set to a special address such as a broadcast address. Example: 192.168.1.100 In the event of using an IPv6 address: A 128-bit IPv6 address is divided into eight 16-bit fields. Each 16-bit field consists of four colon-separated hexadecimal numbers. In each 16-bit field, leading zeros can be omitted for simplicity. However, at least one digit must be reserved in each field. To achieve further simplicity, you can use a double colon (::) in place of a series of zeros. A double colon can be used only once in an IPv6 address. It can also represent the neighboring consecutive zeros at the beginning or end of an IPv6 address. An IPv6 address cannot be set to a special one, such as a network address, loopback address, or multicast address. Example: fc00::1234
        Mask/Prefix	When an IPv4 address is used, this parameter indicates the subnet mask of the storage IP address and identifies the subnet to which the IP address belongs. When an IPv6 address is used, this parameter indicates the prefix length of the IPv6 address.
        Port	Indicates the port used by an IP address. Click to go to the Manage Bond Port page. You can configure a port as required. For details, see Managing Bond Ports.

     2. On the storage network configuration page, click Preview.
        • If the storage IP addresses have been configured, the system displays the storage IP address of each node.
        • If the storage IP addresses have not been configured, the system displays the storage IP addresses to be allocated to storage nodes.
          

          If a previewed IP address is not the planned IP address of a storage node, change it.

          You can click More on the right of the node whose storage IP address needs to be changed and select Modify.

     3. Click Submit.
     4. After the storage network is configured successfully, click Next.
