You can use Oracle ILOM to set the next boot device on your server. Setting the next boot device in Oracle ILOM causes your server to boot from the selected device on the next power reset. For subsequent power resets, the server automatically reverts to booting from the boot order list.
Your selection is only valid the next time the server is powered on. To permanently modify the boot order, see Modify the Boot Order (BIOS).
-> set /HOST boot_device=bootDevice
Where bootDevice is one of the following: default, pxe, disk, diagnostic, cdrom, bios, or floppy
