loader utility. Windows Boot Manager can be found in the Start Options menu of
the Host Server UEFI.
9. The Windows Boot Manager option is inserted as the first boot option in the boot
order list of the Host Server UEFI. The CD/DVD boot is the second device in the
boot order list.
10. Upon reboot, the system boots from the LUN set up on the SAN.
Directing a UEFI-based Server to a Windows Server 2008,
2008 R2, 2012, or 2012 R2 Operating System Image
(Installed as UEFI-aware) Already Installed on the SAN
This installation procedure assumes a LUN exists in the SAN storage device, is zoned
appropriately to the host adapter’s WWN, and a UEFI-aware operating system resides
on the target LUN.
To direct a UEFI-based server to a Windows Server operating system image:
1. Enable network boot in the Emulex UEFI configuration utility.
2. Configure the boot target and LUN in the Emulex UEFI configuration utility to
point to your desired target.
3. Select Boot Manager from the System UEFI configuration manager.
4. Select Add Boot Option.
5. Identify the desired target in the list, and continue down the explorer path until you
locate the bootmgfw.efi file. This file is the boot loader utility for your Windows
Server 2008, 2008 R2, 2012, or 2012 R2 UEFI-aware operating system installation.
6. Input a boot device description (for example, Win2K8_UEFI_SAN) and optional
data (if desired) for this device and select Commit Changes.
7. From the Windows Boot Manager, select Change Boot Order.
8. Move your previous input description name (Win2K8_UEFI_SAN) to the desired
position in the boot order.
9. Select Commit Changes. The Start Options list now reflects the boot order changes.
Upon reboot, the server is able to boot from this target LUN on the SAN.
GUID Partition Table
The GPT was introduced as part of the EFI initiative. GPT provides a more flexible
mechanism for partitioning disks than the older MBR partitioning scheme that has been
common to PCs. MBR supports four primary partitions per hard drive and a maximum
partition size of 2 TB. If the disk is larger than 2 TB (the maximum partition size in a
legacy MBR), the size of this partition is marked as 2 TB and the rest of the disk is
ignored.
The GPT disk itself can support a volume up to 2 64 blocks in length (for 512-byte blocks,
this is 9.44 ZB). The GPT disk can also theoretically support unlimited partitions.
Note: By default, Microsoft Windows Server 2008, 2008 R2, 2012, and 2012 R2 installs
with a GPT-formatted disk on an UEFI-aware server.
