System Boot Sequence Considerations¶
During StarlingX software installation, each host must boot from different devices at different times. In some cases, you may need to adjust the boot order.
The first controller node must be booted initially from a removable storage device to install an operating system. The host then reboots from the hard drive.
Each remaining host must be booted initially from the network using PXE to install an operating system. The host then reboots from the hard drive.
To facilitate this process, ensure that the hard drive does not already contain a bootable operating system, and set the following boot order in the BIOS.
removable storage device (USB flash drive or DVD drive)
network (PXE), over an interface connected to the internal management network
network (PXE), over an interface connected to the PXE boot network
For BIOS configuration details, refer to the OEM documentation supplied with the worker node.
If a host contains a bootable hard drive, either erase the drive beforehand, or ensure that the host is set to boot from the correct source for initial configuration. If necessary, you can change the boot device at boot time by pressing a dedicated key. For more information, refer to the OEM documentation for the worker node.
