Information Update 3

Microsoft Updates

The following issues are documented on the Microsoft®Help and Support

website at support.microsoft.com:

• Systems running Microsoft Windows Server

2003 or Windows

Server 2008 cannot be set to hibernation if they have more than 4 GB of

memory installed. For more information about enabling hibernation on

systems with more than 4 GB of memory, see the knowledge base article

KB888575 at

microsoft.com

• Microsoft Windows Server 2008 R2 cannot be installed or run on systems

with 1 TB of system memory and cannot resume from hibernation mode.

This issue may occur either in Unified Extensible Firmware Interface

(UEFI) or in legacy BIOS modes. For more information, see the knowledge

base article KB980598

microsoft.com

• Systems running Microsoft Windows Server 2008 do not support iSCSI

boot when they have an SD card installed in the internal SD module. In

addition, iSCSI boot does not work when an external USB storage device is

plugged into the system. For more information, see the knowledge base

article KB968410 at

microsoft.com

Flash Memory

The VFlash media provided by Dell is not partitioned to support the iDRAC6

Enterprise virtual flash feature. When you use the virtual flash feature for the

first time, you are prompted to format the media using the iDRAC GUI.

Red Hat Enterprise Linux 5.4 Address Limitation

With 1 TB (When Memory RAS Mode is Not Used)

Red Hat®Enterprise Linux®5.4 has an address limitation with 1 TB of

system memory. To install Red Hat Enterprise Linux 5.4, use the mem=

1024M boot time switch. The system does not boot to the operating system

unless a boot time switch mem=1024G is used. For more information, see the

knowledge base article at kbase.redhat.com/faq/docs/DOC-25412.

4Information Update

Microsoft Windows Server 2003 R2 SP2 (x64)

Edition With SP2 Limitation With 1 TB System

Memory (When Memory RAS Mode is Not Used)

The system does not boot to the operating system with 1 TB of system

memory. To resolve this issue, set the memory RAS mode to sparing or mirror.

After installing the operating system, add a boot time switch mem=1046528

or /burnmemory=2048 in the boot.ini file before disabling the RAS mode

for subsequent boots.

MAC Address Labels

For security reasons, the embedded NIC and iDRAC6 Enterprise MAC

address labels provided with your system cannot be affixed after they have

been removed.

NOTE: The labels are located on the system identification panel on the front of the

system.

System Limitations With an Optional 10 Gb I/O

Riser

The 10 Gb I/O riser provides two 10 Gb SFP+ ports using a Broadcom®

57711 controller in addition to two 1 GbE ports. The following are the

limitations with the 10 Gb I/O riser:

• To ensure system power redundancy, the 10 Gb I/O riser requires all four

power supplies to be connected to the AC power source. The system power

becomes non-redundant if one of the power supplies is removed.

CAUTION: A power supply failure or removal of another power supply after the

system power becomes non-redundant can lead to a system failure and results in

loss of data.

• Wake On LAN (WOL) is not supported on the 10 Gb

SFP+

ports due to

Broadcom 57711 design limitations. However, WOL is supported on the

two 1 GbE ports available on the riser.

Information Update 5

System Limitations With an Optional PCIe Riser

The PCIe riser expands the number of PCIe expansion slots available in the

system to 10. Due to the limitation of 64 KB I/O address space on the Intel®

IA32 architecture and the I/O granularity of 4 KB set by the PCI bridge

specification, you can exceed the I/O resources if you populate the slots with

adapters which require more than 4 KB of I/O address space. The system does

not complete POST if 64 KB I/O address space is exceeded. For more

information on supported adapters, see the Dell™ PowerEdge™ R910

Hardware Owner's Manual at support.dell.com/manuals.

Dell Update Package Information

During the Dell Update Package (DUP) installation process, you may see

messages related to the following:

• Request for system reboot before the DUP installation is complete

• Windows hardware detection

• Windows hardware configuration problem

• Re-enumeration of VFlash and momentary drive letter changes in

Windows

CAUTION: Ensure that you do not perform write operations during DUP

installation on VFlash.

It is recommended that you disable the OS Watchdog Timer in the system

BIOS when running the BIOS DUP. The system may reboot in the middle of

an update and results in corrupted flash if:

• The

OS Watchdog Timer

in the system BIOS is enabled

• The timer expires (if set too short)

NIC Teaming

The system has Broadcom embedded NICs that can be teamed with other

vendors such as Intel. It is recommended that you use Broadcom teaming

driver.

6Information Update

Dell PERC H800 Storage Adapter Slot Limitation

(With PERC H700i as the Internal Storage

Controller)

The system supports up to two PERC H800 adapters. There is no slot

limitation when only one H800 adapter is installed. However, when you install

two H800 adapters in a system with a PERC H700i internal storage adapter,

one of the H800 adapters must be installed in slot 7 (x16 Gen 2 slot). If you

run embedded system diagnostics without an H800 adapter installed in slot 7,

a software error occurs.

Under the same condition, if you enable Collect System Inventory on Restart

(CSIOR), you may not be able to boot to the operating system. You can

enable/disable CSIOR through the iDRAC Configuration Utility by pressing

<Ctrl><E> during boot up. For more information, see the iDRAC User’s

Guide at support.dell.com/manuals.

Dell Lifecycle Controller System Services

Limitations

Table 1. Lifecycle Controller System Services Issues

Cause Solution

SAS6/iR or PERC H200 has virtual disks

in an inactive or non-optimal state.

Make the virtual disks active before

booting to Lifecycle Controller.

PERC H200 or 6 Gbps SAS HBA are

configured with two virtual disks.

This is a known issue. Do not create

multiple virtual disks using either PERC

H200 or 6 Gbps SAS HBA.
