After installing an OS to a Sun Server X3-2L (formerly X4270 M3) you may see an issue where the system seems to ignore the boot order in the BIOS and boot from another device such as the network.

For example, you may have a RAID card set as the first boot device in the BIOS as follows :

RAID:PCIE6:(Bus 50 Dev 00)PCI RAID Adapter
PXE:NET0:IBA XE Slot 4000 v2196
PXE:NET1:IBA XE Slot 4001 v2196
PXE:NET2:IBA XE Slot 8800 v2196
PXE:NET3:IBA XE Slot 8801 v2196


Then when trying to boot the installed OS, the system may ignore the RAID boot device and try to boot from the network PXE:NET0 device instead, followed by other devices below this should it fail or be terminated by hitting the ESC key.

If all devices in the boot list fail or are skipped (by pressing ESC key) you *MIGHT* find that the OS then boots.

You may also find that selecting the RAID controller directly from the boot menu (pressing F8 during POST) *MAY* allow the OS to boot first time.
