Creating a VBS Using a New Node

This section describes how 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

        Node Type

        The value can be New node or Management node.

        • New node: suitable for scenarios where all nodes with the VBS compute role are added. In this mode, you need to enter the management IP address and authentication information of the nodes.
        • Management node: suitable for scenarios where management nodes with the VBS compute role are added. This mode is recommended for management nodes. In this mode, you can directly select the management IP address of a management node without entering authentication information.

        Management IP Address

        Management IP address of the node.

        NOTE:
        • The management network IP address cannot use the same subnet as the storage, control, service (iSCSI), or replication network.
        • When the management network is isolated, the management IP address must be able to communicate with the internal management network.
        • Both IPv4 and IPv6 addresses are supported. The management network IP addresses of all nodes must be of the same type.

        Cabinet

        Cabinet where the node resides.

        [Value range]

        • The value contains 1 to 256 characters.
        • The value can contain only letters, digits, underscores (_), and hyphens (-).
        • The value cannot start or end with a space.

        Node Name

        Name of the node.

        [Value range]

        • The name contains 1 to 64 characters.
        • The name can contain only letters, digits, hyphens (-), underscores (_), and periods (.), and must start and end with a letter or digit. A period (.) cannot be adjacent to a period (.), hyphen (-), or underscore (_).

        Chassis

        Chassis where the node resides.

        Slot

        Serial number of the slot where the node resides.

        Node Role

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

        Configure Firewall

        Whether to automatically configure the firewall for the node. 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

        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 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

        User name for logging in to the node.

        Password

        Password used for logging in to the node.

        Password of root

        Password of user root for logging in to the node.

        NOTE:

        If you log in to the node not as user root, 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 a 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 nodes and install the network management components.

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

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

    1. Set 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, storage IP addresses must be configured for all nodes in advance.
      • If you select No, the system selects available IP addresses from the storage IP address range in the list on the right and assigns them to the nodes (one IP address for each node).
      Table 2 describes related parameters.
      Table 2 Storage network parameters

      Parameter

      Description

      Storage IP Address Range

      IP address range of the storage network.

      NOTE:
      • In the multi-IP scenario, the storage network can use the same subnet as the control network, but cannot use the same subnet as the internal management, external management, service (iSCSI), and replication networks. The IP address range of the storage network cannot use the same subnet as the IP addresses of other ports on the nodes.
      • In non-multi-IP scenarios, the storage network cannot use the same subnet as the internal management, external management, service (iSCSI), and replication networks. The IP address range of the storage network cannot use the same subnet as the IP addresses of other ports on the nodes.
      • When IPv4 addresses are used:
        • A 32-bit IPv4 address is divided into four 8-bit fields that are expressed in dotted decimal notation.
        • Each field of an 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 IP address cannot be set to a special address such as a broadcast address.
        • Example: 192.168.1.100
      • When IPv6 addresses are used:
        • 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 of an IPv6 address, 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 address. It can also represent the neighboring consecutive zeros at the beginning or end of an address.
        • An IP address cannot be a special address, such as 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 storage IP address ranges. A maximum of 300 storage IP address ranges can be configured.

    2. Click Preview.

      The system automatically configures the storage IP addresses for 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 Settings to reconfigure.

    2. After the installation is successful, you can choose to configure 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.
