Boot the Fuel Slave nodes

Before you boot the Fuel Slave nodes, verify that you have completed the following tasks:

  1. Install the Fuel Master node <install_install_fuel_master_node>.
  2. If you plan using RAID arrays, configure you RAID-attached devices first.
  3. Configure the network:
    • If you use bare-metal servers, verify that the Fuel Slave nodes are physically connected to the same network as the Fuel Master node.
    • If you use virtual servers, verify that the Fuel Slave nodes are bridged to the same network as the Fuel Master node. The Fuel Master node and the Fuel Slave nodes must be in the same L2 network segment.

To boot the Fuel Slave nodes:

  1. Power on a Fuel Slave node.

  2. Boot the Fuel Slave node through PXE using one of the following options:

    • Modify the boot order in BIOS to PXE boot.
    • Press the appropriate key to initiate a PXE boot.

    Warning

    If the Fuel Slave node has several network interfaces, enable the PXE boot on the interface that is on the same network as Admin (PXE) network on the Fuel Master node.

  3. Repeat the procedure for all the Fuel Slave nodes you will use for your OpenStack environment.

Boot workflow of a Fuel Slave node

The boot workflow of a Fuel Slave node does not require any user interaction. For general understanding of the processes that take place in the system when the Fuel Slave node is booting, get acquainted with the boot procedure:

  1. The Fuel Slave node sends out a DHCP discovery request and gets the response from the Fuel Master node that runs the DHCP server.
  2. On receiving the response, the Fuel Slave node fetches the PXELINUX bootloader and the bootstrap image from the Fuel Master node's TFTP server, and boots into it.
  3. On loading the image, the Fuel Slave node reports readiness and configuration to the Fuel Master node.

The number of discovered Fuel Slave nodes appears in the Fuel web UI. When all nodes boot, you can create an OpenStack environment.
