Intel RAID Controller Troubleshooting Guide: Some of my hard drives show up during POST and some do not

Drives not showing up in post can be caused by a variety of problems. Please check the
following:

• Are you using the latest BIOS and firmware for the server board and the latest firmware
for the RAID card?

• System memory limitations limit the number and size of option ROMs that can be used
in the system. If you place too many adapters in the system, or the ROMs on the
adapters you have installed take up too much space in memory, the option ROM on
your RAID controller may not expand correctly and will not show the hard drives that are
connected to it. Try turning off the expansion ROMs for any on-board device that is not
being used. For example, if your server board includes a SCSI controller that is not
being used, disable this SCSI controller in BIOS setup. For a list of tested peripherals
with the Intel RAID controller, download the Tested Operating System and Adapter List
from http://support.intel.com/support/motherboards/server.

• If you are using a Zero Channel Card that utilizes the on board IO controller, such as an
on-board SCSI or Serial ATA controller, the Option ROM scan for the on-board device
must be enabled. If it is not enabled, drives connected to that device will not show up
during POST.

• Confirm that the drive power cables are firmly connected. If you are using a chassis
with a backplane, make sure the power and SCSI cables are properly applied to the
backplane and the hard drives are firmly seated in the backplane.

• Check your SCSI ID numbers. SCSI devices must each have a unique ID on the SCSI
bus. This number is set with jumpers on the device. ID numbers should be set starting
at 0 and they must be set lower than 8 if booting from the drive. If you are using a
server chassis with a backplane, the device IDs are usually automatically set by the
backplane, but may be manually configurable.

• Check for proper termination on the SCSI bus. Intel RAID cards are by default autoterminating.

If your hard drives still do not show during post, please call your customer support
representative. Note the following information and have it ready to assist the support engineer:

• Model number and firmware revision of the RAID controller you are using.
• Manufacturer and model number of other add-in adapters installed in your system.
• Manufacturer and model number of hard drives installed in the system.
• Identify the type of termination used for the card.
• The SCSI IDs of the devices on your SCSI bus.
• The number and type of SCSI channels.
• Manufacturer and model of the memory used in the system and on the RAID controller
and whether it is on the tested memory list.

Intel RAID Controller Troubleshooting Guide: My system appears to power on, however there is no video

Check the following:

• Look for a blinking cursor in the top left corner of the screen. If the cursor is there, wait
5 minutes to determine if the system will continue the boot process.

• Your RAID controller may require the addition of a memory module. Verify that the
module is included on the tested memory list for the RAID controller. The tested
memory list is available at http://support.intel.com/support/motherboards/server.
Remove and reseat the memory module if memory on the card is installed in a memory
socket.

• Remove all add-in cards, including the RAID controller. See if the server boots using
only the on-board components. If successful, add the cards back in one at a time,
rebooting between each addition. This will help you determine the card that is causing
the problem.

• Listen for any beep codes and refer to your product documentation. A 1-3 beep code
from the RAID card indicates normal operation.

• Make sure the monitor is turned on and the video cable is plugged in completely. If you
are using a switch box to share a monitor between multiple servers, make sure you have
the switch set to the correct server.

If you are unable to resolve this issue, contact your customer support representative. Gather
the following information before making your phone call:

• The make and model server board and RAID controller are you using.
• The version of BIOS and firmware of the server board.
• The version of the firmware on the RAID controller.
• The PBA (Product Board Assembly) number on the board.
• The chassis and power supply the server is using.
• Note what is displayed on the monitor or any sounds emanating from the server system.
