Installing in the attended mode

Limitations

  • Shingled magnetic recording (SMR) HDDs cannot be used for system and are not displayed in the installer.

Prerequisites

  • A bootable USB drive, an IPMI virtual drive, or a PXE server is prepared, as described in Preparing the bootable media.
  • The time is synchronized via NTP on all nodes in the same cluster and the nodes can access the NTP server.
  • If you want to change the default MTU, it must be configured on the network hardware.

To install in the attended mode

  1. Configure the server to boot from the chosen media.
  2. Boot the server and wait for the Welcome screen.
  3. On the Welcome screen, select Install Virtuozzo Hybrid Infrastructure.
  4. On Step 1, carefully read and accept the End-User License Agreement.
  5. On Step 2, configure the network:

    1. Specify a unique host name: either a fully qualified domain name (<hostname>.<domainname>) or a short name (<hostname>).

      The only way to change the host name later is by contacting the technical support.

    2. Configure your network cards. Usually the network is configured automatically (via DHCP). If manual configuration is required, select a network card, click Configure…, and specify the necessary parameters.
    3. Set MTU on each network card. By default, MTU is set to 1500, while 9000 is recommended.

      The MTU value must be the same across the entire network.

      • If you are integrating Virtuozzo Hybrid Infrastructure into an existing network, adjust the MTU value to that of the network.
      • If you are deploying Virtuozzo Hybrid Infrastructure from scratch alongside a new network, set the MTU value to the recommended 9000.
    4. According to network recommendations, you may want to create bonded and virtual local area network (VLAN) interfaces for network security and better performance:

  6. On Step 3, ensure that the Network Time toggle switch is turned on, and then select your time zone. The date and time will be set via NTP. You will need an Internet connection for synchronization to complete.

    We only support the UTC time zone. Changing the time zone for nodes is not supported and may lead to system unavailability.

  7. On Step 4, specify what type of node you are installing:

    • If you want to register the node in the admin panel manually after the installation, select Skip cluster configuration.
  8. On Step 5, select a disk for the operating system:

    All information on all disks recognized by the installer will be destroyed.

  9. On Step 6, enter and confirm the password for the root account, and then click Start installation.

Once the installation is complete, the node will reboot automatically. The admin panel IP address will be shown in the welcome prompt.

What's next

  • After deploying the primary node, proceed to deploy the required amount of secondary nodes.
  • When all the required nodes are displayed in the admin panel on the Infrastructure > Nodes screen as Unassigned, proceed to create the storage cluster, as outlined in Deployment and configuration.
  • If you skipped cluster configuration on step 4 and want to add the unassigned node manually:
