Windows Server 2008 R2 on Integrity Servers Release Notes

Event Log
Corrected hardware errors
Issue Integrity Servers running Windows Server 2008 R2 might receive Windows
Event Log messages describing Corrected Hardware Errors for memory and
processor components. These messages from the Microsoft WHEA-LOGGER
service can occur several times daily on large memory configurations running
under high load.
Servers All Integrity
Workaround These event log messages do not indicate a problem. The underlying hardware
is operating correctly.
Extensible Firmware Interface (EFI) and EFI-based Setup Utility (EBSU)
I/O card firmware values display as unknown
Issue The EBSU Maintain Firmware feature displays some I/O card firmware values
as unknown in the Local version column. This occurs when the card firmware
does not return a data structure that EBSU recognizes because the card firmware
is configured for 32-bit systems, it lacks an EFI driver, or has corrupted firmware.
Servers All Integrity
Workaround Flash the card firmware to correct the problem. If the card still has unknown
values after flashing it and resetting the system, contact your local support
specialist or visit http://www.hp.com/support/itaniumservers for help.
Windows does not start on Reboot after restoring system image
Issue Occasionally, if you use EBSU before restoring the system image to a Fibre
Channel boot controller or if only restoring the system image to a Fibre Channel
boot controller, the system does not boot to Windows and might do either of
the following:
• Stop at the EFI prompt
• Restart WinPe, if the reinstall DVD is still inserted
This occurs because the Windows boot entry is missing from the boot menu.
Servers HP Integrity BL8x0 i2 server blades
Workaround To create the missing entry, enter the following command at the EFI prompt:
EFI_drive_letter:\EFI\Microsoft\Boot\bootmgfw.efi
Where EFI_drive_letter: is the mapping of the drive corresponding to the
EFI System Partition (for example: fs:). The boot process then continues
normally. The bootmgfw command automatically creates the Windows boot
entry.
Fibre Channel
