Creating a VBS Using a New Node

Procedure

1. Choose Services > Block Service > VBS.
2. Click Create VBS and select New Node.

   The Add Node page is displayed.

3. Click Batch Import Node or Manually Add Node to add nodes.
   • Batch Import Node

     Click Download the template to download the template. Fill information about the nodes to be added in the template and save it locally. Click , select the template, and click Upload. The nodes are imported to the system in a batch.

   • Manually Add Node
     1. Set parameters for a node. Table 1 describes related parameters.

        Table 1 Node parameters

        Parameter	Description
        Management IP Address	Indicates the management IP address of the node.
        Cabinet	Indicates the cabinet where the node resides.
        Node Name	Indicates the name of the node.
        Chassis	Indicates the chassis where the node resides.
        Slot	Indicates the number of the slot where the node resides.
        Node Model	Indicates the model of the server where the node resides.
        Node Role	Indicates the role of the node. VBS compute is automatically selected.
        Installation Mode	Indicates the installation mode of the node. Possible options are Regular installation and Pre-installation. If you select Regular installation, set Username, Password, and Password of root in the Authentication area for authentication.
        Username	Indicates the user name for logging in to the authentication server.
        Password	Indicates the user password.
        Password of root	Indicates the password of user root.

     2. Click OK to add the node to the list.
     3. Click Submit to configure the node and install the network management components.
        

        If the configuration fails or the network management components fail to be installed, click Restore Factory Setting to delete data.

     4. Click Next.
     5. Configure the storage network.
        1. Determine whether to select Yes or No in Use Configured Storage IP Address Only. If you select Yes, the system only allocates configured storage IP addresses in the specified IP address range to the nodes. To select this option, all nodes must be configured with storage IP addresses in advance.
           Table 2 describes related parameters.

           Table 2 Storage network parameters

           Parameter	Description
           IP Address Range	Indicates the IP address range of the storage network. NOTE: 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 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
           Subnet Mask	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.

           

           You can click to configure multiple IP address ranges.

        2. Click Preview.

           The system automatically configures the storage IP addresses to the nodes and refreshes the network information in the lower part of the page.

           

           • After modifying the network configurations, if you do not click Preview, you can click Reset to restore to the previous previewed network information.
           • You can click More on the right of a node and select Manage Bond Port to manage bond ports of the node.
           • If you select No in Use Configured Storage IP Address Only, you can click More on the right of a node and select Modify to modify the node's storage IP address and port.
        3. Click Submit.
        4. After the storage network is configured successfully, click Next.

4. Install nodes.
   1. (Optional) If the installation fails, you can click Restore Factory Setting to reconfigure the nodes.
   2. Click Install.
   3. (Optional) After the installation is successful, you can expand the capacities of the storage pool, replication cluster, and iSCSI service.
      

      After the installation is complete, a message is displayed, prompting you to select whether to enable the NTP client on a compute node.

      • If the NTP client provided by other components or services has been configured on the compute node, select No to disable the NTP client of the storage system.
      • If no NTP client provided by other components or services is configured on the compute node, select Yes to enable the NTP client of the storage system.
   4. Click Finish.
