Creating a VBS Using a New Node

This operation enables you to create a VBS service on a node and interconnect it with the iSCSI access initiated by an application server.

Procedure

  1. Choose Resources > Access > 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
      1. Click Download the template to download the template locally. Fill the information in the template, click and select the template, and then click Upload. The nodes are imported to the system in a batch.
      2. Select the newly imported nodes and click Authenticate.

        On the Authentication page, select an installation mode for the nodes. Possible options are Regular installation and Pre-installation. If you select Regular installation, set Username, Password, and Password of root for authentication.

        Select Pre-installation when the VBS software has been pre-installed for compute nodes during the block service installation.

    • 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 a 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 Role

        Indicates the role of the node. VBS compute is automatically selected. You can select Storage as required.

        Firewall

        Whether to automatically configure the node firewall. This function is enabled by default. If the firewall is disabled, manually enable it. For details, see the Communication Matrix to ensure that all ports of compute nodes are configured with correct firewall rules.

        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.

        NOTE:

        Select Pre-installation when the VBS software has been pre-installed for compute nodes during the block service installation.

        iBMC Password

        After this function is enabled, you need to configure a user name and password for authenticating the iBMC server.

        NOTE:

        This parameter needs to be set only for nodes that contain storage roles.

        Username

        Indicates the user name for logging in to the node.

        Password

        Indicates the password used for logging in to the node.

        Password of root

        Indicates the password of user root for logging in to the node.

        NOTE:

        If you log in to the node as a non-root user, you need to enter the password of user root.

      2. Click OK to add the node to the list.
      • You can click More on the right of a node and select Modify or Delete to manage it.
      • You can also select a newly added node and click Authenticate to authenticate the node again.
      • You can also select the newly added node that contains the Storage role and click Set iBMC Password to configure the user name and password for authenticating the iBMC server.

  4. 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.

  5. Click Next.
  6. Configure the storage network.

    1. Determine whether to select Yes or No in 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. To select this option, all nodes must be configured with storage IP addresses in advance.
      Table 2 describes the parameters.
      Table 2 Storage network parameters

      Parameter

      Description

      Storage 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

      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.

      You can click Add Storage IP Address Range 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.

  7. Install nodes.

    1. Click Install.

      If the installation fails, you can click Restore Factory Defaults to reconfigure.

    2. (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.
    3. Click Finish.
