Configuring system boot mode and order

To configure the system boot mode and order, use the information in this topic.

When you select Boot Options under Server Configuration , you can configure the system boot mode and order.

Note
No unauthenticated in-band method is allowed to change security related system settings. For example, Secure Boot must NOT be able to configure over unauthenticated in-band APIs from the OS or UEFI shell. This includes OneCLI running in-band and obtaining temporary credentials using IPMI, or any tools and APIs to configure Secure Boot, TPM, UEFI Setup password related settings. All security related settings must require proper authentication with sufficient privilege.

For the system boot mode, the following two options are available:

UEFI Boot
Select this option to configure a server that supports Unified Extensible Firmware Interface (UEFI). If you are booting UEFI-enabled operating systems, this option might shorten boot time by disabling legacy option ROMs.
Legacy Boot
Select this option if you are configuring a server to boot an operating system that requires legacy (BIOS) firmware. Select this option only if you are booting non-UEFI enabled operating systems.

To configure the system boot order, select a device from the list of Available devices and click the right arrow to add the device to the boot order. To remove a device from the boot order, select a device from the boot order list and click the left arrow to move the device back to the list of available devices. To change the boot order, select a device and click the up or down arrow to move the device up or down in priority.

When you make a change to the boot order, you must select a restart option before applying the change. The following options are available:
  • Restart server immediately: The boot order changes are saved and the server is restarted immediately without shutting down the operating system.
  • Restart server normally: The boot order changes are saved and the operating system is shutdown before restarting the server.
  • Manually restart later: The boot order changes will be saved, but will not take effect until the next time the server is rebooted.
