IBM CONFIDENTIAL 2
Overview
This document is intended to assist the Service and Support teams in some potential
problems they may likely encounter on the x366.

IBM CONFIDENTIAL 3
I. Mechanical Concerns
A. Microprocessor tray removal
When removing the microprocessor tray through the front of the server, the memory
cards or planar will be damaged unless the memory cards are removed first. Please note
that all Fans must be removed as well before CPU tray can be removed. Also during
removal of the tray, the microprocessor heat sinks may hit or interfere with the top of the
chassis making removal difficult. To help alleviate the heat sink chassis interference, lift
up on the top of the chassis while removing the tray. A recommended lift point is via the
drive bay. Please see http://www-307.ibm.com/pc/support/site.wss/migr-60199.html for
additional information on tray removal.

IBM CONFIDENTIAL 4
B. SAS Hard Disk Backplane
Connectors on both the SAS hard disk drives and SAS backplane can become damaged if
the SAS backplane is not seated properly which can keep the Hard Disk Drives from
aligning properly on the backplane. Insure the SAS backplane is fully seated properly
before installing the hard disks. Three tabs on the backplane assembly must fully seat
into appropriate slots in the chassis.
C. x366 Capacitors: Shearing Off Elpida Memory Dimms
Warning:
The system may have intermittent memory failures if the DIMM decoupling capacitors
are broken. PC3200 DIMMs have a characteristic physical design where decoupling
capacitors are placed near the connector edge of the DIMM. The placement places the
capacitors in a position where the decoupling capacitors can easily be sheared off.
This is not a problem when one is careful to place the DIMM in the connector. A problem
may arise if the unwary hand places the DIMM in between the connectors. The capacitors
are small and will easily break off if the DIMM is placed in between the connectors.
Correct Action:
DIMMs must be carefully placed in the connector by aligning the DIMMs inside the
connector card guide and aligning the card so the connector key and the connector match.
Please see Memory Handling Guide at
http://www.samsung.com/Products/Semiconductor/Support/Label_CodeInfo/memory_m
odule_handling_guide.pdf . The guide on Samsung’s website applies to all memory
manufacturers and is the method approved by IBM.
DDR2 memory DIMMs cannot be handled in the same manner as the prior generation
DDR1 memory DIMMs. DDR1 DIMMs are more tolerant to mishandling. Improper
DDR2 DIMM handling can result in mechanical damage to the components on the
DIMMs such as cracked solder joints and solder joint separation.
D. Unable to disengage left front Bezel Cover Latch
When harddrives are installed in the two left most slots, it may be difficult and/or
impossible to press the left front bezel latch to remove the front cover. The solution is to
power the machine off and remove the left two drives, then remove bezel by pressing the
left and right bezel release buttons.

IBM CONFIDENTIAL 5
E. Power protection cap falls off
Under normal conditions, the protection cap will prevent inadvertent actuation of the
power switch. There have been reports where the protection caps will not remain
attached to the bezel. The power button protection cap is now being heat-stake attached.
Please contact the IBM support to obtain a replacement.
F. Force Power On jumper on I/O board s labeled incorrectly in PD Guide
The Force Power On jumper on the I/O board is labeled incorrectly in the PD Guide. The
layout in the PD Guide show pins 1 2 3 from left to right but actually they are 3 2 1. Pins
1 and 2 should be jumpered to force power on.
Please note that as of right now, the Force Power On Jumper does not by-pass the front
panel switch. Once the jumper is moved, the fans will spin up and the server will appear
to power on and hang at CP 0b. with nothing appearing on the screen. The CR11 led on
the PCI-X board will also be out. You must press the front panel power button in order
for the server to fully power on. Once the button is depressed, the CP codes will scroll
through as normal, the PCI-X CR11 led will come on solid, and shortly after the server
will post text on the screen as normal.
G. Bent Pins on memory board and possible F2 Checkpoint hang
If the server hangs during post at checkpoint F2 listed on Super I/O card, then check the
memory card/s for possible bent pins. Replace the card if found to have bent pins.
H. USB Floppy drive does not ship with the server
A floppy drive is not included with this server. If there are updates that can only be done
through bootable diskette, then the customer must provide his own USB floppy drive.
I. Problems Accessing CDROM
If a customer is having problems accessing CDROM’s during normal operation, then have them
update the CPLD code to version 1.01. CPLD code can be obtained at http://www-
307.ibm.com/pc/support/site.wss/ MIGR-60630.html .

IBM CONFIDENTIAL 6
II. Lightpath
A. System Information Light comes on when BMC System Event Log Full
The baseboard management controller (BMC) system event log (SEL) can have a
tendency to fill up quickly with many informational type messages. Once the BMC log is
70% full (approx 358 entries), the system bang light is illuminated. In environments
where A/C power is cycled often, the tendency for to log to fill quickly is particularly a
problem. Flashing the BMC firmware will also add many informational type messages
to the SEL.
To clear the Bang Light for a full SEL, Restart the server and press F1 when prompted to start the
Configuration/Setup Utility program.
a. Select Advanced Setup;
b. Select Baseboard management controller (BMC) settings;
c. Select BMC System Event Log
d. Select Clear error logs to clear the BMC system event log.
They can also be cleared online using the SMBridge command line tools. Please refer to
http://www-307.ibm.com/pc/support/site.wss/ MIGR-57729.html for additional
information on SMBridge.
B. PCI slot Attention and Power LED’s reversed
In other systems, when viewing the PCI slots from the rear of the system, a PCI error
condition can be seen because the amber “attention” LED is light-piped to the rear of the
system. On the x366 however, the PCI slot Attention and Power LED’s are reversed so
the green “power” LED is seen on any populated slot when the system is powered on. To
see whether there is a PCI error, first check the LightPath panel. If the “PCI” LED is lit,
then remove the top cover and view the individual slot Attention LED’s to determine
which slot is affected.

IBM CONFIDENTIAL 7
C. LED indicators for a faulty VRM
For the pluggable VRMs, initial BMC firmware levels will illuminate the VRM, CPU
and PCI board LEDs during a VRM fault. Newer code versions will illuminate only the
VRM and CPU. Regardless of the BMC firmware level, sensor circuitry is unable to
tell if a VRM fault is the result of a CPU or VRM failure. Since VRMs are less
expensive, a VRM should be replaced, prior to replacing the CPU.
Add the level of BMC code that has the fix.
SP LED blinks yellow in normal operation or good condition.
D. Dim LED’s on front panel indicator:
Power off the system, remove the white flex Op Panel cable from the I/O board, and
inspect the metal contact for damage. If the metal contacts are lifted from the cable
substrate, or if there are signs of the metal being scraped, the cable should be replaced.
The plastic contact separators on the I/O board connector (where the flex cable plugs in)
are sharp and can scrape the metal contacts on either end of the cable when the flex cable
is inserted. Please see http://www-307.ibm.com/pc/support/site.wss/ MIGR-60141.html
for further information.
In addition, this symptom may result from a blown fuse on the IO Adapter, often as a
result of problems with the flex cable mentioned above.

IBM CONFIDENTIAL 8
E. Disabling onboard Broadcom Nics result in Information Light coming on:
The System Info (!) LED on the Operator Information Panel & Log LED on the
Lightpath Panel will come on at POST and stay on if the on-board NIC is disabled in
BIOS Setup. This is not a hardware problem. The "Planar/PCI Device is disabled or not
responding" message will show in the System event Log (SEL). This message is the
cause of the LED's coming on. In the upcoming BIOS release this message will be
removed. If you re-enable the on-board NIC, or clear the log, the System Info (!) & Log
LEDs should go out if your logs are less than 70% full. What actually happens is the
LEDs stay lit until you AC Power Cycle the system.
III. Power Supply Considerations
A single x366 power supply is rated a 1300 Watts when used with a 220 V ac source, and
is capable of powering a fully loaded server without redundancy. With 110 V ac, this
power rating falls to 650 Watts for the same single power supply.
A. System configuration
A single 110V ac power supply can support a maximum configuration of 1
microprocessor, 2 PCI-X adapters, 3 hard disk drives, and 4 DIMMs. If you exceed this
configuration you must either install a second power supply or use 220V ac input.
If two power supplies are installed on 110V, the server will not support a full
configuration (700-800W) with redundancy. 220V must be used in order to maintain full
redundancy with a full configuration.
B. Fuel Gauge
The NONRED LED will be illuminated when the server is operating with non-redundant
power. If a power supply or its ac power source fails, the system will move to an over
spec state.
The Over spec LED will be illuminated when there is insufficient power to power the
system. When in an over spec state, an optional power supply can be added if only one
power supply is installed. Another alternative to fixing the over spec condition is to use
a 220V ac input source.
C. Power Supply Failure and Replacement
It is advisable to check the System Event Log (SEL) for other error conditions prior to
replacing a suspected bad power supply. As an example, a shorted circuit board would
likely show improper voltage levels in the SEL due to current limiting circuit protection.

IBM CONFIDENTIAL 9
IV. Machine Will Not Power On
If the X366 system will not power up, please check for the following in order.
A. If an RSA2 Slimline option was just installed, System may be temporarily hung.
Allow system at least 15 minutes to complete POST if a new RSA2 Slimline has just
been installed. Reason: the default option firmware results in a 10-12 minute temporary
hang with x366 BIOS. If the system eventually completes POST, flash the BIOS and
BMC code to the latest level. The new BIOS/BMC reduces the 15 minute wait at POST.
Then flash update the RSA2 Slimline. See http://www-307.ibm.com/pc/support/site.wss/
MIGR-59095.html for additional information.
B. Power off the system, remove the white flex Op Panel cable from the I/O board, and
inspect the metal contact for damage. If the metal contacts are lifted from the cable
substrate, or if there are signs of the metal being scraped, the cable should be replaced.
The plastic contact separators on the I/O board connector (where the flex cable plugs in)
are sharp and can scrape the metal contacts on either end of the cable when the flex cable
is inserted. Another symptom of a defective Flex Op cable would be dim leds on the
front panel display of the server. Please see http://www-
307.ibm.com/pc/support/site.wss/ MIGR-60141.html for further information.
C. Over heated inductors at these locations L14, L17, L28, L29, and L32 on the PCI-X
board can cause power faults which will prevent the server from powering on. Please see
ECA064 for further information
V. RSA2 and BMC Related Issues and Errors
A. SMBridge and Syscon Utilities
1. The SMBridge utility and instructions on how to use it can be obtained via the
web here http://www-307.ibm.com/pc/support/site.wss/ MIGR-57729.html . Use
this to pull BMC data remotely. The default IP of the BMC is 10.1.1.97, Subnet
255.255.255.0. The IP can be changed in F1 is required.
2. Syscon is another utility available to pull BMC data that differs slightly from
SMBridge. Use the Same BMC IP to retrieve the logs. Please contact your
regional IBM Support for this utility if needed.
3. Please contact IBM Support to have the BMC data analyzed.

IBM CONFIDENTIAL 10
B. RSA Configuration Settings and PCI slot information disappears in bios
If a customer states they can no longer see RSA configuration or PCI slot information
under Advanced Settings in F1, have them update their BMC code to 1.07 or later and
bios level 1.03 or later.
C. RSA does not communicate with BMC immediately on AC power Cycle
After an AC power cycle (power removed and reapplied to the server), the RSA does not
log events from the BMC for first 2 minutes. HOWEVER, if you wait 2- 2 ½ minutes
before pressing power, the RSA WILL record BMC events during the power up
sequence. If PD is being done and you cannot boot the machine, please wait two minutes
before pressing the power button and then pull BMC and RSA logs.
D. Cannot Change RSA2 IP in Bios
On certain occasions after an RSA 2 Slimline adapter is installed, you will not be able to
change the IP address, Subnet, or Gateway for the card from 4.9.1.1 in F1. This error
condition is a result of BMC to RSA communication failure. Flashing the RSA to the
correct x366 RSA code will correct the problem.
Ignoring the settings in F1, use another machine and crossover cable to the RSA and use
the following IP to access the RSA via web interface:
Default RSA2 IP: 192.168.70.125
Once logged in, flash the RSA to current firmware to correct the error.
E. DHCP enabled by default on RSA2
The default network setting on an RSA2 Slimline adapter is DHCP first, then Static.
There will be a 3-4 minute delay period in network access to the card each time the card
is restarted. It is during this period that the RSA will be looking for an IP from a DHCP
server. If it is unable to obtain a valid IP, it will revert to the default static IP and will
once again be accessible from the network. It is recommended to set to Static IP if the
card is not using DHCP.
F. 1602 Communication failure and/or long POST after RSA2 Installation:
If an RSA2 Slimline option was just installed, System may be temporarily hung on
POST. Allow system at least 15 minutes to complete POST if a new RSA2 Slimline has
just been installed. Reason: the default option firmware results in a 10-12 minute
temporary hang with x366 BIOS. If the system eventually completes POST, flash the

IBM CONFIDENTIAL 11
BIOS and BMC code to the latest level. The new BIOS/BMC reduces the 15 minute wait
at POST. Then flash update the RSA2 Slimline. See http://www-
307.ibm.com/pc/support/site.wss/ MIGR-59095.html for additional information.
Additional symptoms may include a hang at checkpoint c7 and/or a 1602
communications error on the monitor.
G. Flashing RSA and BMC
-RSAII can be updated remotely (via web interface. Default IP address
192.168.70.125, subnet 255.255.255.0) or through Windows using Wflash or Linux
using Lflash.
-BMC is a separate update done via diskette or Update Express CD.
H. Error in Logs: “Redundant PCI Bridge link failed”
If this message is seen in the hardware logs, please check the cpu card for any possible
bent pins. If unable to correct the bent pin, then replace the cpu card.
I. Error in logs: “Machine check asserted – SPINT.Hurricane”
Symptom: A false SPINT could occur in the hardware event log.
The initial x366 systems that shipped are missing one rework that could allow false
SPINTs to occur. If the system has all of the following symptoms, then the CPU card
should be replaced.
* CPU Card PN = 13M8079
* BMC event log indicates that a Machine check occurred
* SPINT VERSION 2 DUMP:
First Fire 01
Machine Check Capture register 08C108 = 00000000 00010000
Action: Replace CPU Card with Card P/N 13M8092
J. BMC log fills up rapidly
The LOG light path LED lights when the BMC log is 70% full, approximately 370
entries.
Depending on the system configuration, each A/C power cycle results in about 100-150
entries created in the log.

IBM CONFIDENTIAL 12
Warm boots or Ctrl-Alt-Del results in only 4-7 entries.
During initial setup or extensive Problem Determination, the log can fill rapidly because
A/C power cycles are common when installing boards, CPU's, memory, etc.
Unlike the RSA log which wraps new entries, no further entries can be created in the
BMC log when it is full with 512 entries..
To insure there is sufficient space for future events, Servicers should clear the BMC log
just prior to leaving the call.
Please contact Support for instructions on how to clear the BMC logs and refer to internal
Retain Tip H026578.
K. Below is a diagram of the boot order communication between CPU, BMC, and
RSA2
VI. SAS and ServeRAID 8i Related Issues
A. ServeRAID logs can only be pulled from OS ServeRAID Manager
ServeRAID logs can ONLY be pulled from ServeRAID Manager in the operating system
with ServeRAID Manager Agent running. If the Agent is not running, logs cannot be
pulled. Unlike previous ServeRAID adapters, the 8i does not contain NVRAM so the
ServeRAID CD will not work.
BIOS
BMC
RSA II

IBM CONFIDENTIAL 13
B. No Current Red Hat released 8i Drivers
Currently there are no released versions of device drivers for 8i RHEL 3 U5. The beta is
in test and it can not be given to customer at this time. It is targeted for release in the 3
rd
quarter of 2005. The 8i driver can be compiled using the code on 8i Support CD as per
the instruction documented in the Installation guide under books directory of the CD as
per instructions in Appendix A and that is supported.
C. Possible data loss with 8i 5EE raid array
A problem has been found that can put data at risk in 5EE arrays during compaction and
expansion cycles. While the risk can be mitigated in some cases by re-synchronizing the
array, it is strongly recommended that ServeRAID 8i arrays not be configured in a 5EE
configuration until a fix for the problem has been released. Target for the fix is Sept,
2005. See Retain Tip H184325 for further information.
D. Replacement harddrive will not rebuild
Under certain circumstances replacement drives will not rebuild when placed back into
an array. Here are a few steps you can try to start the rebuild if t does not kickoff on
replacement:
1. Pull the drive out, wait 30 seconds and then place back in
2. Reboot the server and repeat step 1
3. Check the harddrive firmware in ServeRAID manager. If the firmware on the
replacement drive is 511 or any other drive has 511 code, then contact the
Backoffice to obtain a Beta copy of the SAS harddrive firmware update utility.
Please see section VI. E for further information on updating the SAS drive
Firmware.
511 code was a prerelease code level and should have never gone out to the
field, however some FRU stock drives have been identified to contain this code
level. If they do contain this level, it must be flashed to the release level 512.
PE is aware of the rebuild problem and will be issuing an 8i code update in the future to
address this.

IBM CONFIDENTIAL 14
E. Cannot Update SAS harddrive firmware with ServeRAID 8i installed
Currently there is a beta SAS harddrive firmware update program available through IBM
Support. Please note that if you are asked to update the SAS harddrive firmware and the
customer has an 8i installed, they will need to remove the 8i in order for the drives to
update. Our Engineering team is aware of the issue and is working on a resolution.
F. 8i Data scrubbing is off by default
Data scrubbing on a ServeRAID 8i is off by default. It is recommended that the customer
turn this feature on for maximum data protection using either ServeRAID Manager
within the OS or using the ServeRAID CD.
G. “Command Timeout” Error on boot
If the customer sees a Command Timeout error on boot, the drive that times out is
defective and needs to be replaced.
H. "kernel panic" error may be seen during POST
Linux messages may appear at POST when the ServeRAID 8i initializes because the 8i
runs on a Linux base.
For example, a kernel panic may be displayed.
In that case, the 8i controller SAS subsystem should be debugged per the x366 Problem
Determination Guide.
Under certain circumstances pulling the card, rebooting to F1 and restoring defaults, then
placing the card back in and powering up will correct the error.
I. ServeRAID logs do not show drive array assignment
For RAID-1 and RAID-10 (mirrored) arrays, the ServeRAID Manager configuration logs
(Raid1x.log) file and the ARCCONF GETCONFIG log will not indicate which physical
drives are mirrored together. RAID-5, RAID-50 and other parity arrays will indicate the
stripe order in these logs. The implementation of mirrored disks in the SAS environment
do not uses stripe orders or stripe units so this information, was inadvertently left out.

IBM CONFIDENTIAL 15
J. Front Bezel Slot id’s do not match the ServeRAID Configuration Log SCSI id’s
If a customer is using an 8i and a ServeRAID support archive or an ARCCONF
GETCONFIG log is pulled, please note that the drive assignments in the logs will not
correlate to the front bezel id’s. For GA level systems, the ServeRAID Manager GUI
will correlate the ID to Slot properly. Only the ServeRAID logs are incorrect. If a
specific action must be taken on a physical disk based on the ServeRAID log
information, verify the correct disk is selected by comparing the disk serial numbers
before proceeding. See the diagram below for a better understanding of how the
ServeRAID configuration logs correlate to the front bezel layout:
K. Windows 2003, ARCSAS.SYS System Event Errors, Event ID 0
The ServeRAID-8i ARCSAS.SYS driver may produce red bulleted errors in the
Windows 2003 System Event log. This error is actually informational, as the ServeRAID
driver was designed to take advantage of enhancements made for this new storage
architecture in Windows 2003 Service Pack 1. Applying Service Pack 1 or higher will
remove the ARCSAS.SYS error events and will improve overall performance of the SAS
subsystem.

VII. Miscellaneous
A. Onboard Broadcom Q&A
Here are a few basic questions customers may ask regarding the default operation of the
onboard broadcom nic.
1. Why is the Default setting on Nic1 10/100 full?
Default setting on the NIC is set to Auto-Negotiate, and should link at the speed
of the switch when system power is on. When in stand-by, the speed setting on
port 1 downgrades to 10/100 due to IPMI (BMC) settings. 10/100 is the default
set by Broadcom for the IPMI link (into the BMC) when in standby. This setting
has remained at default because we were not aware of any need to change it.
2. Is there any reason why the customer should not change this default value?
IPMI (BMC) communications have not been tested with the IPMI link set to other
than 10/100. It may work at 1000, but support would be limited in case of
errors/faults. With the link set to '1000'or to 'all', the port should link at 1000
when in stand-by.
3. Are there any plans to change this?
Presently there are no plans. But if there are enough requests into
Marketing/Sales, the PDT could make the change & submit for testing, then
firmware update can be posted on website, and subsequently EC'd into card
manufacturing.
B. 00180102 PCI device resource allocation failure on POST:
This POST error code in likely to be encountered by customers. The work around is
described on the web here http://www-307.ibm.com/pc/support/site.wss/ MIGR-
59032.html and is repeated below for convenience.
One (1) or more of the following can be tried to resolve the symptom:
•If multiple drive adapters are set up to boot, including onboard, disable the BIOS
on any adapter that does not require booting. The onboard devices can be
completely disabled in the Configuration/Setup utility program.
•Other adapters may use the ROM space, including the slim line Remote
Supervisor Adapter (RSA-2), if installed. Disabling the BIOS on these cards may
remedy the problem.
•Load defaults in SCSI select utility program.

IBM CONFIDENTIAL 17
•Disable PXE boot for onboard Ethernet if not needed.
•Take any network adapter out of the startup sequence.
•Reallocate the boot order of the adapters so that the adapters with larger boot
ROMs get more space to load.
For additional information on this error please refer to the website document.
C. PCI scan sequence
The server scans devices and PCI-X slots to assign system resources in the following
order: integrated Ethernet controller, integrated SAS controller, and then PCI and PCI-X
slots 1 through 6. Note: To change the order in which the server scans devices and PCI-X
slots, start the Configuration/Setup Utility program and select Start Options from the
main menu.
The startup sequence under Start Options specifies the scan order in which the server
checks devices to find a boot record. The server starts from the first boot record that it
finds. 00180102 PCI device resource allocation failures can sometimes be resolved by
changing the startup sequence.
D. Windows 2000 Remote Install Blue Screens w/o SP3
Symptom: Windows 2000 Server Remote Installation Blue screens
Solution:
Since the x366 requires a SCSI (SAS) device driver that is not available on the base
Windows 2000 installation disk, use a version of Windows 2000 Server that includes at
least Service Pack 3 updates for remote installations. Refer to Microsoft Knowledge
Base Article - 302098. “INACCESSIBLE_BOOT_DEVICE" message after changing a
SCSI adapter resource.
E. IBM Director 4.21 requires patching before running on an x366
In order for IBM Director 4.21 to run correctly on an x366 it must be patched. Failure to
do so will result in false errors. Please review the document located here for further
information:
ftp://ftp.software.ibm.com/pc/pccbbs/pc_servers_pdf/dir4.21_x366_known_issues.pdf

IBM CONFIDENTIAL 18
VIII. Performance Related Issues
Configuring Memory for Optimum Performance
1. The number of installed memory DIMMs is critical to optimal performance because it
is not possible for the chipset to yield high performance if it is waiting on memory
accesses. The optimal configuration is with all 16 DIMM slots populated. If price is a
concern, eight DIMMS will usually provide similar performance compared to 16
DIMMS. The maximum difference is usually about 3 - 5%. Four total DIMMs will be
slower than 8 DIMMS by up to 5-10% for some applications.
2. Use more than one memory card to improve performance. The x366 supports four
memory cards and each card supports four DIMM's. With four DIMM's in a single
memory card the x366 will be about 50% slower than with four DIMMS in two
memory cards.
3. The x366 is set by factory default with the highest memory scrubbing protection, but
memory scrubbing reduces performance. To optimize memory performance (to have
identical redundance to DELL and HP systems) navigate in BIOS Setup: under
Advanced Functions/Memory, set High Performance Memory Array (HPMA).
4. The x366 is set with factory defaults to optimize database transaction processing.
However, if the server will perform file server or web server tasks optimize the x366
BIOS configuration with the following:
- go to BIOS Setup, under Advanced Functions/CPU, and set HW Prefetch to
DISABLED.
Prefetch forces the processors to prefetch extra cache lines for every request. For
applications that don't take advantage of prefetch (JAVA, File Server, Web Server) this
slows performance. Disabling Prefetch can improve performance 10 - 20% for these
applications.

For Systems which can be rebooted, e.g. new installs or not in production
1. Run Update Xpress
Hint: a modified Update Xpress CD with the latest is available from the Back Office for
limited distribution.
2. Run CPLD update diskette. Remove AC power after update to take effect.
3. Run ServeRAID 8i Support CD if 8i installed
4. Run SAS HDD Firmware Update CD
5. Update RSA2 firmware remotely per the procedure below
For Systems required to remain in production (code becomes effective at next planned reboot)
1. Download and run either the Windows or Linux Packages for BIOS, BMC, RSA2, and
Diagnostics
2. Work with customer to plan the update for ServeRAID 8i, SAS HDD firmware, and/or
RSA2 firmware.
Notes
