2 System Information
Boot Drive Priority
The on-board SCSI controller has two channels, A and B. Channel A is typically used to control the Hot
Swap SCSI drives. Channel B is typically used to control the internal non-hot swap SCSI drives. On each
SCSI channel, the NetServer scans for a boot device starting at device ID 0 and proceeds up from there. The
HP NetServer's boot order (BIOS search order for a boot device) should be considered, when connecting
cables from the on board SCSI channels. A SCSI drive’s boot priority is set by the drive’s location in the boot
order.
You can change this boot order using the Setup Utility (BIOS) and the SCSI Configuration Utility during the
boot process. By default the NetServer searches for boot devices in this order:
1. IDE CD-ROM drive
2. Flexible disk drive
3. SCSI A bus (typically Hot Swap Mass Storage Cage)
4. SCSI B bus (typically non-Hot Swap internal SCSI devices)
5. PCI Slot P1
6. PCI Slot P2
7. PCI slot P3
8. PCI slot P4
9. PCI slot P5
10. PCI slot P6
11. PCI slot P7
12. PCI slot P8
IRQ Settings
The BIOS automatically assigns the IRQs (hardware interrupts) for each PCI slot and embedded device in
the HP NetServer during boot. These assignments trigger the NOS to enable the APIC (Advanced
Programmable Interrupt Controller). APIC takes advantage of the expanded set of non-conflicting IRQs for
those accessory boards requiring more than one IRQ per slot. APIC provides up to four dedicated interrupts
for each PCI slot.
These automatic IRQ assignments can be changed in the setup screen (F2).
Connector Pinouts
Video Connector Pinouts
The built-in video uses the standard 15-pin analog display pinout configuration. The pinouts for your monitor
may vary. For the pinouts for your monitor, refer to the manual that came with your monitor.

Memory Guidelines
The standard LH 3000/3000r configuration ships with one 128 MB DIMM in socket 0.
l
Add DIMMs of these sizes:
◊
128 MB
◊
256 MB
◊
512 MB
◊
1 GB
l
Add memory in any order to the four sockets.
l
You can mix DIMM sizes. For example, you may place a 1 GB DIMM next to a 128 Mb DIMM.
l
Maximum configuration is 4 GB.
l
Do not rock the DIMM into place, but apply firm and even pressure until it is seated in the
socket.
l
Use only HP-supported DIMMs.
NOTE
If non-HP DIMMs are used, the NetServer will report this during boot.
Mass Storage Guidelines
The HP NetServer standard configuration is:
l
16
One hot-swap mass storage cage (primary)
◊

Hot Addition and Replacement of Hot Plug PCI Boards
The PCI Hot Plug option is NOS-dependent. To use the Hot Plug option, the PCI board must have a hot plug
compliant driver and a Hot Plug Utility for the respective NOS. The Hot Plug Utility is used to turn power
off/on to the PCI slot, while the HP NetServer continues to operate normally.
NOTE
Hot Removal or online deletion of an adapter board and reconfiguring of that
adapter from the NetServer is not supported.

Processor Guidelines
The HP NetServer LH 3000/3000r supports two processors in primary and secondary slots. The NetServer
ships with one processor and an accompanying VRM in the primary slots. The processor and VRM are on
the system board.

CAUTION
Do not remove the processor from its bag until you are ready to install it. Make sure
the bag remains sealed. Before you remove a processor from the anti-static
container, touch a grounded, unpainted metal surface on the HP NetServer to
discharge static electricity.
Do not change the processor speed switches as this can result in unreliable or
intermittent performance, and data integrity may also be at risk.
l
Use only processor upgrade kits with the same HP product number. This ensures the processor
type, clock speed, and cache size match, and processor stepping are compatible.
l
Be sure that the VRM and the processor module associated with it are both in either the primary
or the secondary pair of slots.

4 Diagnostics
Diagnostics
Two types of diagnostics support the LH 3000:
• Boot Diagnostics
These are routines that are executed automatically when the LH 3000 is booted on, and before
loading of the Network Operating System (NOS) begins.
• DiagTools
This is a functional test suite that comes with the LH 3000 and other HP NetServers.
Boot Diagnostics
Boot diagnostics include a number of types of tests:
• Built-in Self-Tests
These are tests that execute within specific components such as the processors or controllers
(for example, the front panel controller).
• Power-On Self-Test
This is a set of test routines executed by the boot processor. Faults detected in this testing are
reported as POST error codes. These codes will appear on the display monitor and the front
panel LCD while POST executes. These messages will also be recorded in the System Event
Log (SEL) which is accessible through the front panel LCD display and Event Log Reporting
Utility (Navigator CD-ROM). The POST routines can display an error message on the video
display screen, the speaker beeps twice as the message appears.
• Initialization and Configuration Routines
Before the network operating system (NOS) is loaded, the system will move applicable pieces
of firmware into main memory (for example the PCI Video BIOS or the SCSI BIOS) and initialize
peripheral channels (for example the SCSI channels). If the display reports a particular
procedure is underway and the system simply stops, you may infer that the displayed procedure
has crashed the system. For example, if the boot process stops while the SCSI firmware is
loading and initializing the SCSI channels, then there may be problems with the SCSI cables or
components. Use the Setup utility or the SCSI Configuration utility to make any changes to the
configuration. If you cannot correct an error, refer to General System Problems.
• Beep codes occur when errors cannot be viewed on the screen. Typically these signal fatal test
errors that occur before the video BIOS is loaded and messages can appear on the display.
These errors may generate a message to the System Event Log (SEL) which may be accessed
through the front panel LCD display or the Event Log Reporting Utility.
Minimum Requirements for Boot Diagnostics
As a minimum, in order to start running boot diagnostics the NetServer must find a working processor with
which to boot, and data path to the ROM BIOS which supplies the bootstrap firmware. The system soon
needs space in main memory into which firmware will be moved to support NOS operations after booting.
HP NetServer DiagTools
The purpose of hardware diagnostic software is to provide tools for checking for serious hardware problems.
By design, diagnostic software executes simple tests of each hardware component in turn. Usually, such
35
Chapter 4
Diagnostics
tests create assurance that hardware is not the source of system problems. This allows the user to eliminate
hardware as the cause of the problem and to focus on operating system configuration parameters, network
connections, and application software configuration parameters as the source of the problem.
If hardware problems are confirmed, the diagnostic software program can sometimes detect and diagnose
the subsystem or specific system component that is the cause of the problem. In addition, diagnostic tools
can capture information that allows support personnel to quickly assess the condition of system.
In order to be effective, diagnostic software tools must be used in the context of a wider troubleshooting
procedure.
DiagTools Capabilities
DiagTools for HP NetServers is a set of off-line diagnostic tests, including tests for system and processor
components, memory and storage elements, ports, and input/output devices. DiagTools is supplied on the
HP NetServer Navigator with HP NetServer series LC, LH, LP and LX. The user prepares DiagTools
software for use by transferring it to diskette. Then the DiagTools diskette is used to boot the server. A basic
suite of tools checks key NetServer components, and a menu of advanced tests is available for in-depth
testing.
DiagTools has the capability to test the following components:
l
system board
l
processors
l
memory modules
l
hard disk drives
l
flexible disk drives
l
keyboards
l
serial ports
l
parallel ports
l
video monitor
l
CD-ROM drives
DiagTools is an off-line diagnostic test series. Off-line diagnostics do not use the main operating system (OS)
of the HP NetServer. The alternate DiagTools OS has far fewer features than the full-fledged OS. Thus, its
capabilities are limited to a set of basic tests and a series of advanced tests. In addition, DiagTools does not
use any tests that might write over and thus destroy user data. Tests that require user inputs or decisions are
left to the advanced series of tests.
You can use DiagTools to support troubleshooting to carry out the tasks listed below:
• display a high-level inventory of the system under test
• save and print a detailed inventory of hardware components
• conduct a basic test of components listed in the system inventory
• display “PASSED” or “FAILED” overall results of basic tests
• record detailed test results of basic system tests
• display a menu of advanced tests
• select and run one or a series of advanced tests
• add the record of results of advanced tests to the record of basic tests
• view a list to locate the meaning of a specific error code
• view one or more steps to help confirm and isolate error conditions
• browse the Support Ticket, which contains the detailed inventories and test results
• add comments to the Support Ticket
If you have TopTools remote management software installed and configured for use with DiagTools, you can
accomplish any of the above lists of tasks remotely.

Diagnostics
Advantages and Limitations of Hardware Diagnostics
Off-line diagnostic software is useful in making sure that has been eliminated as the cause for possible
system problems. Such diagnostic tools can easily be shipped with a server, and they are relatively easy to
use.
However, off-line diagnostic software should be used only by experienced personnel who can take a wider
view of its limitations, which include:
• booting the server from the diagnostics diskette
• no access to operating system error logs, since the OS is not operating at the same time as the
diagnostic tools
• limited ability to test only a single component at a time
• inability to indicate problems with wrongly configured systems or the network
Event Log Display Utility
This utility shows events logged in the System Event Log (SEL) and provides advisory information. Brief
descriptions of the events are also available through the front panel LCD display. To access this utility, boot
the system with the Navigator CD-ROM in the CD-ROM drive. When the Navigator Main Menu comes up,
select "NetServer Utilities", then "More NetServer Utilities," and then "Event Log Report Utility."
Be patient. The utility may take a while to read the event log from non-volatile memory.
The Event Log Display Utility is also available through DiagTools.
POST Routines
The POSTS executed during startup are:

Troubleshooting Checklist
These instructions do not generally cover third-party components or devices. Refer to the documentation that
comes with the third-party device for diagnostic and troubleshooting information. When replacing the
processor or system board, make sure all previously installed components are removed from the original
processor or system board and are installed on the replacement board.
NOTE
This information assumes that the customer is booting MS-DOS (note that
DiagTools is based on MS-DOS). If the customer is not using MS-DOS, reboot the
system with a DOS diskette.
When troubleshooting:
• First make sure that the system is configured properly. Most system problems are the result of
incorrect system and SCSI subsystem configurations.
• If it is a network-related error, determine if the user has enough memory and hard disk drive
capacity. Run the diagnostics for the network interface cards. Consult with the network
operating system manual.
• If it is a hardware error, follow the instructions to log users off the LAN and power down the
server. Boot the Power-on Self-Tests (POSTs). If you get an error, look up Error Messages
for further instructions. If the POSTs pass, you can run the HP DiagTools. Besides the POSTs
and HP NetServer DiagTools disk, the standard set of tools recommended for troubleshooting
are:

9. Verify the error.
General System Problems
No lights are on and no error message appears.
If the server does not work (no lights are on) and no error message appears, check the following:
1. Make sure that all cables and power cords are plugged into their proper receptacles.
2. Make sure that the AC outlet is working. If the server is plugged into a switched multiple-outlet
box, make sure that the switch on the outlet box is turned on.
3. Make sure that the server is turned on (the power-on light should be green and the fans should
be on).
4. Turn the server off, wait at least twenty seconds, then turn the server back on to see if the
failure can be cleared.
5. Make sure that all boards are installed properly and the processor module or modules are
installed in the correct slot. They must be seated firmly in their slots and any cables must be
connected firmly.
6. If your server stopped working after you installed a new board, remove the board and turn on
the server. If your server now works, determine how to set the jumpers and switches on the
board if there are any. If the new board is preventing the server from powering on, it's apt to
have a serious electrical problem.
7. If your server still does not work, remove all boards and options that you have installed (do not
remove the flexible or hard disk drives) and turn on the server.
8. Add the boards and options one at a time to determine which one is causing the problem.
9. If you have added any memory, make sure that the DIMM modules are seated properly in the
board.
Power goes off on the server and doesn't come back on
When certain critical conditions exist, the server shuts down all power.
NOTE
It is a good idea to run the Event Log Display Utility on the HP NetServer Navigator
CD-ROM as part of regular maintenance procedures so that you can check to see if
any problems have been logged to the file. Also, this file needs to be purged at
times since the error log can eventually fill up. Errors are time stamped with either a
Real-Time Clock (default) or the POST Capture time stamp. See the HP NetServer
Navigator CD-ROM, NetServer Utilities menu, for additional information on this
feature.
The critical conditions that may shut down the server are:
• critical temperature fluctuations or changes
• voltage problems (external AC line)
• power supply failure
If the server powers off, and before you try a restart, do the following:
1. First check to make sure power is getting to the server. Plug a known working device into the
power outlet.
52
Chapter 5
Troubleshooting
2. Access the System Event Log (SEL) through the front panel LCD display. You can do this when
the system is running, or you can do this while the system is powered down, but still plugged in
(standby mode).
3. Review the Troubleshooting Checklist to check for basic server integrity.
4. Check for proper ventilation for the server. The server should have at least six inches of space
around the front and back for proper airflow.
5. Check the system specifications and make sure the environmental temperature and voltage are
in the specified guidelines.
6. Make sure all system fans are working.
7. Boot the HP NetServer Navigator CD-ROM and run the Error Logging utility. If the system
powers up and immediately shuts down, CMOS might be corrupted. You may need to clear
CMOS and reconfigure your system.
8. Check the error log and note which errors have occurred that shut down the system.
If you are having voltage fluctuation problems, go to Power Problems.
Note that temperature problems can also be caused by a fluctuating power supply.
Monitor the system to make sure you are not experiencing further temperature and voltage problems.
The server stops working (hangs)
If the server stops working, do the following:
1. Review the Troubleshooting Checklist before you continue.
2. If the system hangs, power the system off and on, as it is a more complete reset rather than
using Ctrl+Alt+Del.
3. If the POST find an error, check the connection and/or replace the faulty part.
4. If the problem persists, remove and replace the system board.
5. Once a problem has been found with a part, verify that it is the problem by duplicating the error.
The server powers-off then powers on again by itself
The server has an Automatic Server Restart (ASR) feature that is set to enabled. The ASR feature is used
with the NetServer Assistant product. When certain conditions occur the server shuts down all power, then
twenty seconds later restarts the server. ASR is enabled as the default. You can disable this feature if you
want. To read about the effects of automatic server restart, see the NetServer Assistant product. The
conditions that shut down and restart the server are operating system problems that affect the system timers.
The system does not start (boot)
Check that DIMMs are installed on the System Board. If the above are fine, do the following:
1. Review the Troubleshooting Checklist before you continue.
2. If memory problems are being experienced:
a. Power the system off and on as it is a complete reset instead of using Ctrl+Alt+Del.
b. If the POST finds a problem, check the error against the Error Messages and correct the
problem.
3. Check that all DIMMs are installed correctly:
a. Check that the DIMMs comply with the Memory Guidelines.
b. Reseat the DIMMs on the system board.
53
Chapter 5
Troubleshooting
4. To check that the system board is installed and configured correctly:
5. If the HP NetServer indicates there is not enough memory, and if the customer does not want to
add memory, try these steps:
a. Disable any drivers that are not necessary for the application being run, and/or the network.
b. Delete memory resident or TSRs (terminate and stay resident) programs.
To solve the problem with steps 5a-5b, the customer must be willing to give up functionality in exchange for
more memory.
6. For memory conflicts (two boards or drivers are trying to use the same memory addresses),
change the addresses used by the memory
For information about the board addresses, see the Setup Utility.
7. Once a suspect part has been found, verify that it is the problem by reinstalling the part and
duplicating the error.
Memory Problems
The memory modules are DIMMs. Note that some HP NetServers require that memory must be installed only
in certain sockets or banks, sometimes in multiples (for example, 2 or 4 at a time).
NOTE
If the POSTs (displayed at power-on time) indicate a defective memory module.
Replace the defective module.
1. Review the Troubleshooting Checklist before you continue.
2. If memory problems are being experienced, power the system off and on. This performs a "cold"
restart, rather than a "warm" restart (as it does when you press Ctrl+Alt+Del).
3. Check the System Event Log for messages indicating memory errors.
4. Run the DiagTools memory test.
5. Reseat the DIMMs.
6. To check that the modules are installed and configured correctly:
a. Run the Setup Utility and check the configuration.
b. Install one known good DIMM. If you still receive an error, replace the system board.
If the error goes away, add another DIMM and reboot again. Continue this process until you
have installed all DIMMs or you experience a failure.
Replace the defective DIMM.
7. Once a suspect part has been found, verify that it is the cause of the problem by reinstalling the
part and attempting to duplicate the error. Also install it in another memory socket to confirm
whether or not the socket is defective.

Troubleshooting
Network Interface Card Problems
See the appropriate Network Interface Card documentation.
Symptoms:
The adapter can't connect to the network.
1. Make sure the cabling is installed properly.
Most hub and switch connections require straight-through cable; consult their documentation. If
you're directly connecting two computers (with no hub or other device), use a “crossover” cable.
2. Verify that there are no resource conflicts between the NIC and any other accessories in the HP
NetServer. Check the Setup Utility.
3. Check any LEDs on the adapter at the back of the computer to see if they show activity. No
activity on the LEDs probably indicates a bad network cable, hub connection or other network
error.
4. Make sure you're using the latest and correct drivers. Make sure the drivers are intended for
this adapter.
5. Make sure the port on the switch or hub (or other device) has the same duplex setting as the
adapter.
If you configured the adapter for full duplex, make sure the switch port is also configured for full
duplex. Setting the wrong duplex mode can degrade performance, cause data loss, or result in
lost connections.
6. Test the adapter as directed in the installation tasks for each operating system. Also check the
“README” files on the support disk.
Power Problems
Symptoms:
A fan is not working.
The power LED does not light.
1. Review the Troubleshooting Checklist before you continue.
2. Verify that the AC power source is good:
a. If the system fans are audible or a control panel light is on, the power is on.
b. Verify the circuit breaker for the AC power outlet.
c. If the breaker was off, check that all devices connected the HP NetServer share the same
circuit breaker and are the only devices on it. Reset the circuit breaker after reconfiguring the
devices, if need be.
d. Verify that the AC power outlet is not faulty. Test it by plugging in a known-good device.
e. Verify that the third-wire ground is isolated from other grounds and is at ground potential.
3. Verify all cable connections:
58
◊
AC power cords from AC source outlet to server.
◊
DC Power supply cables to all HP NetServer PCBs
Chapter 5
Troubleshooting
◊
DC power supply cables to disk drives and/or mass storage cages
4. If the fans aren't audible and the above steps are verified, check that power is getting to all fans.
HP NetServers have multiple fans. All fans run when power is turned on; all are off when power
is off.
With the power supply connected to the system board, check the power supply's voltages.
5. If voltages are not present:
a. Turn off AC power.
b. Disconnect the power cords for 10 minutes in order to reset the power supply's circuitry.
c. Turn on AC power again.
If power is still not getting to the system board, replace the power supply (or power supply
module on some HP NetServer models).
6. If power is getting to the fan but the fan isn't working, replace the fan (or replace the power
supply in HP NetServer models with fans incorporated in the power supply).
7. If the problem continues, replace the power supply module.
8. If, after replacing the power supply, the problem persists:
a. Remove all accessory boards, including any hard disk drive controller board or the video
board the customer might have installed, and reboot the system.
b. Disconnect all mass storage power cords and cables (except those to the boot device) and
reboot the system.
9. If the problem goes away, reinstall the original suspected part to verify that it is causing the
problem.
SCSI Subsystem Problems
Symptoms:
The external SCSI subsystem does not work after installation.
If the external SCSI subsystem does not work after installation, do the following:
1. Review the Troubleshooting Checklist and read "Mass Storage Guidelines" section in
Chapter 2.
2. Run the DiagTools and verify the integrity of the SCSI buses, and other switch settings on the
external storage devices are correct. Verify that each SCSI device is assigned a unique SCSI
ID.
3. Refer to the documentation that came with the SCSI devices for any specific information on
installing them.
4. Make sure that any installed SCSI controller is installed and configured correctly.
5. For any SCSI devices installed in an enclosure external to the HP NetServer chassis, make
sure that Ultra SCSI is disabled on this controller. SCSI devices external to the HP NetServer
chassis are supported in Fast SCSI mode only.
6. Check the SCSI cables for problems that may have been caused by recent computer
maintenance, hardware upgrades, or physical damage.
7. Check the ROM BIOS version to make sure it is the most recently issued version. Booting the
most recent version of the HP NetServer Navigator CD-ROM will automatically report if the
59
Chapter 5
Troubleshooting
BIOS is not current and needs updating (“flashing”). Follow the instructions in the screen to
update the BIOS.
8. Check that the external SCSI subsystem BIOS is being executed properly.
◊
When you start the server, the incrementing count of the RAM appears on the screen. Then
the external SCSI BIOS displays a banner and a copyright notice.
◊
The BIOS then checks for valid devices on the SCSI bus, and reports which devices are
found. If you have installed and configured the SCSI devices correctly, you will see a list
confirming all SCSI devices installed in the system.
◊
If the banner is not displayed the external SCSI controller is not recognized.
9. Verify that the SCSI bus is terminated at both ends. By default, HP SCSI controllers are
terminated. When a device is connected to a connector on the controller, bus termination for
that connector is disabled. Verify that the last device on the bus is terminated.
NOTE
When using LVD SCSI (often referred to as Ultra2 SCSI), termination is typically
provided at the controller and the far end of the cable.
10. Make sure that no device is set to SCSI ID7; this is the SCSI ID used by the SCSI controller.
11. Verify that all SCSI devices are all LVD (low voltage differential) SCSI and that no SE (singleended SCSI devices have been added). Note that SE devices will work on and LVD bus, but
performance will be degraded.
12. Verify that the SCSI hard disk drive that loads the operating system is set to the lowest SCSI
address (usually set to 0).
13. Go into the SCSI Configuration Utility and set the transfer rate lower. The internal and external
SCSI subsystems are typically LVD and will be set to default at the maximum 80 MB/sec. If the
SCSI system works at lower transfer rate, you may infer a connector problem. Try cleaning and
reseating the SCSI cable. Try another cable.
To change the transfer rate for a SCSI device:
a. Press [CTRL] and [C] keys when prompted to enter the SCSI utility.
b. Select the either the internal or external SCSI controller. The internal SCSI channel is
usually port 2000. Press [Enter].
c. After the utility scans the channel, it will list SCSI devices detected. You may change the
transfer rate for a specific device by selecting it, or for the entire channel by changing the
controller. Make your selection and press [Enter].
d. Press [Enter] on Sync Rate to select a new transfer rate.
e. Follow the prompts to save the new setting and exit the utility.
14. If a second hard disk drive is connected to the SCSI cable, check it for proper SCSI address,
SCSI cable connection, proper power, and jumper settings.
15. Disconnect all SCSI devices except the integrated SCSI adapter and the drive at SCSI address
0, and try again. If this fails, try substituting a known good SCSI adapter board and a good hard
disk drive.
The SCSI BIOS has trouble loading.
If the server has trouble loading the SCSI BIOS, do the following:
1. Review the Troubleshooting Checklist before you continue.
60
Chapter 5
Troubleshooting
2. If you installed more than one SCSI controller, make sure that the BIOS for all controllers except
for the boot controller are disabled. This lets the SCSI BIOS for the boot controller load.
3. Determine what the boot device priority is for the HP NetServer model. Verify that the boot
device is set to the correct priority.
The SCSI subsystem does not work at installation.
Many SCSI problems are caused by an incorrect configuration rather than by faulty hardware. If the SCSI
subsystem does not work after installation, do the following:
1. Review the Troubleshooting Checklist and "Mass Storage Guidelines" section in Chapter 2
before you continue.
2. Run the DiagTools and verify the integrity of the SCSI buses, and other switch settings on the
external storage devices are correct. Verify that each SCSI device is assigned a unique SCSI
ID.
3. If you don't see the SCSI BIOS banner during system start:
"Symbios, Inc. SDMS TM V4.0 PCI SCSI BIOS PCI Rev. 2.0, 2.1"
"Copyright 1995, 1998 Symbios, Inc."
"PCI-4.14.04"
and the final message "SCSI BIOS successfully installed" after devices are displayed:
◊
Check the cable connections.
◊
Check the SCSI termination.
4. Run the Setup Utility or SCSI Configuration Utility and verify that the SCSI host bus adapter
(HBA) is properly configured.
The HBA is usually SCSI ID 7.
5. If you installed more than one SCSI adapter, verify that each adapter is set to a separate BIOS
address; or disable the BIOS on all of the adapters except one.
6. For each device, check:
◊
That each device has a unique SCSI address.
◊
In general, when selecting an address for a drive (default address is 0), select the lowest
possible address.
◊
Check that the device's jumpers are set according to the device documentation.
7. Check that the primary SCSI hard disk drive is set to the lowest address (usually set to 0). Each
device (the HBA is also a device) must have a unique and separate SCSI ID number. To solve
this problem, simply set the device ID to something other than that of the HBAs SCSI ID (7). If
the device is a boot drive, then the SCSI ID should be set at 0.
8. Go into the SCSI Configuration Utility and set the transfer rate lower. The internal and external
SCSI subsystems are typically LVD and will be set to default at the maximum 80 MB/sec. If the
SCSI system works at lower transfer rate, you may infer a connector problem. Try cleaning and
reseating the SCSI cable. Try another cable.
To change the transfer rate for a SCSI device:
a. Press [CTRL] and [C] keys when prompted to enter the SCSI utility.
b. Select the either the internal or external SCSI controller. The internal SCSI channel is
usually port 2000. Press [Enter].
61
Chapter 5
Troubleshooting
c. After the utility scans the channel, it will list SCSI devices detected. You may change the
transfer rate for a specific device by selecting it, or for the entire channel by changing the
controller. Make your selection and press [Enter].
d. Press [Enter] on Sync Rate to select a new transfer rate.
e. Follow the prompts to save the new setting and exit the utility.
9. If another hard disk drive is connected to the SCSI bus, check it for unique address, SCSI cable
connection, and power connection.
10. Check the SCSI bus cable for correct orientation, alignment, and seating on the SCSI adapter
and the SCSI device.
11. Check for the correct Hewlett-Packard internal and external SCSI cables.
12. Check that all SCSI devices are connected to power and power-on all SCSI devices before or at
the same time as the HP NetServer to ensure a stable SCSI bus.
13. Watch the boot screen for all SCSI devices to be displayed. For example, in a system with 1
SCSI controller and 2 hard disk drives (one with ID 0 and one with ID 1), if a valid device is
found at device address 0, but not at address 1, you would see these device validation lines on
the boot screen:
Channel x, SCSI ID #n - id info - Drive C: (80h)
If you see this message:
a. Verify that the SCSI hard disk drive is set to address 1.
b. Check the SCSI bus cable for correct orientation, alignment, and seating on the host adapter
and the hard disk drive.
c. Verify that terminators are installed at each end of the SCSI bus, but not on any other
devices. The hot swap cage printed circuit board has automatic termination that disconnects
when a cable is attached.
d. Verify that all SCSI devices on the bus are appropriate for that bus (only single-ended SCSI
devices on the single-ended bus, only differential SCSI devices on the differential bus).
14. If the server still fails to recognize the SCSI drive, disconnect all SCSI devices except the host
adapter and the drive at SCSI address 0 and try again. If the system fails, try substituting a
known good hard disk drive.
15. If the SCSI BIOS has properly identified device 0 and has installed it as drive C, but cannot find
a device at address 1, and in addition, if no further messages are displayed, it indicates the
server cannot load the operating system from device 0, check the following:
a. If a second hard disk drive is connected to the SCSI bus, check it for proper address
selection, SCSI cable connection, and proper power.
b. Check the disk partition.
c. Partition the hard disk drive if required.
16. Use only SCSI devices without built-in terminators.
The HP NetServer embedded controllers are terminated automatically on the hot swap cage or
at the end of the SCSI cable. If you are installing a SCSI device that uses a built-in terminator,
you must remove the terminator from the device before proceeding with the installation.
Use only the HP NetServer SCSI cables for the SCSI hot swap subsystem.
17. Check that all SCSI devices LVD (low voltage differential) SCSI and that no SE (single-ended)
SCSI devices have been added to the bus.
Hot-swap drives shipped by HP are set for LVD operation. Drives set for SE operation may
62
Chapter 5
Troubleshooting
used, but they will slow down the transfer rate considerably. Please refer to the user
documentation for the device to determine which device you are using.
CAUTION
Don't use high voltage differential SCSI devices, they can destroy circuitry on LVD
and SE devices.
18. Disconnect all SCSI devices except the SCSI adapter and the drive at SCSI address 0, and try
again. If this fails, try substituting a known good SCSI adapter and disk drive.
19. Use the Setup Utility to check for resource conflicts, especially if new boards or accessories
have been added.
The SCSI subsystem stops working.
If the SCSI subsystem should stop working, do the following:
1. Review the Troubleshooting Checklist and "Mass Storage Guidelines" in Chapter 2 before
you continue.
2. Run DiagTools. Verify that the SCSI ID and other switch settings are correct and get specific
information or verification that the problem is the SCSI bus.
3. If an accessory board was added recently, check if there is a resource conflict between the new
board and an existing accessory board. Also, if you have changed the options on an existing
board, there may be a resource conflict.
a. Remove the new board and restart the computer. If this corrects the problem, the board is
either defective or it is trying to use a system resource used by the SCSI subsystem.
b. Check if the board is using memory, I/O addresses, or interrupt lines that are also used by
the SCSI subsystem.
4. Check to see if there have been recent changes to any software. For example, has anyone
moved, removed, or changed the configuration files or drivers? Refer to the software
documentation for more information.
5. Check the SCSI cables for problems that may have been caused by recent computer
maintenance, hardware upgrades, or physical damage.
6. If you suspect hardware failure and there are no system error messages, check each
component associated with the failure. Equipment failure is probably the most unlikely reason
for a SCSI subsystem failure.
7. Check the ROM BIOS version associated with the SCSI controller to make sure it is the most
recently issued version.
Video/Monitor Problems
Symptoms:
Nothing is displayed on the monitor.
The monitor is blank and the computer beeps.
The wrong size characters appear on the monitor.
Colors are wrong or there are no colors on the monitor.

63
Chapter 5
Troubleshooting
If you have two video monitors connected, test the monitors to make sure they are working (Step 1-4) then
go to Step 10.
NOTE
The system BIOS will beep if no video hardware is detected. This happens when the
on-board video is disabled and there is no video adapter board installed.
1. Review the Troubleshooting Checklist before you continue.
2. Check the contrast and brightness controls to make sure they are adjusted.
3. Verify the video and power cords are connected to the monitor.
4. Make sure there is adequate power:
a. Check that the display power switch is turned on.
b. Check that the display power cord is connected to an AC power outlet and the video cable
connected to the server's video connector.
c. Plug in a known working device to make sure there is power to the outlet or use the proper
testing device to check the power outlet.
d. Turn the monitor off and on, and if the monitor has a power LED, see if it lights.
e. Turn the Clear Configuration switch on the system board to OFF and reboot the system.
Check if the problem persists.
5. Turn on the HP NetServer and wait a full 2 minutes. Check that the monitor starts displaying
normally.
6. If the problem persists, and if the power cord is detachable, try a known good power cord.
7. Unplug the power cord and wait 30 seconds. Plug in the power cord and turn on the HP
NetServer. Wait a full 2 minutes. Check that the monitor starts displaying normally.

Monitor Notes:
◊
64
When most EGA and VGA monitors are disconnected from the video connector, if the
monitor is working, the screen is white.
Chapter 5
Troubleshooting
◊
When some monitors (such as HP high-resolution monitors) are disconnected from the video
connector, the monitor may be working, although the screen is black.
◊
If the display is black or white when it should be in color, check the monitor cable to see if a
pin is bent. If a pin is bent, slowly but carefully straighten the pin. Replace the cable if the pin
cannot be straightened successfully.
◊
If a monitor tester is available, use it to check the display.
◊
If you suspect the monitor is faulty, replace it with a known good monitor. Then reinstall the
original monitor and duplicate the error.
12. Verify that the monitor is working by plugging it into a know-good HP NetServer or computer.
13. Check to see if the monitor connector's pins are bent. If the pins are bent, slowly but carefully
straighten them.
14. Connect the monitor cable to the HP NetServer video connector and turn on the HP NetServer.
If there is a display, but characters are the wrong size or the display is the wrong color:
a. Check whether the monitor is a color or monochrome monitor.
b. Check that the video cable is properly inserted in the connector on the back of the computer.
c. Check for bent pins on the connectors.
15. If the customer has installed a video board instead of using the built-in video, make sure all
jumpers and switches are set properly on the installed video board. (See the manual for the
video board.)
16. If the monitor displays a badly scrambled image that looks to be the current screen image, then
the monitor is not synchronizing correctly.
◊
If a video board is installed, replace it with a known good one. The video timing setting on
the board may be bad.
◊
If it is the on-board video, replace the system board.
17. If a video board is installed and the built-in video is used:
a. Make sure the video board/built-in video combination is supported. Usually, two video
systems (for example, internal video and a video adapter board) cannot be used at the same
time.
b. If there is still a problem, make sure the board is seated correctly.
c. If there is still a problem, remove the video adapter board, and enable the internal video
system. Verify the problem.
18. If a message appears such as "INVALID CONFIGURATION", run the Setup Utility and press
[F2] during the boot process or boot the HP Navigator CD-ROM) to confirm the server video
configuration. Make sure other accessory boards do not use the same memory addresses as
the HP video system.
19. If the problem is isolated to the built-in video system, replace the system board.
Configuration Problems
Symptoms:
An installed driver cannot find a PCI board.
65
Chapter 5
Troubleshooting
Installing a PCI board which bridges the two system PCI buses (certain adapter boards provide this feature)
can cause previously installed PCI drivers to not recognize their adapter board(s).
To resolve the configuration problem, move the PCI board that has bridging capability to a primary PCI slot.
The configuration cannot be saved and the battery loses power.
Refer to this section if the server frequently loses date and time that may be caused by the battery losing
power.
1. Review the Troubleshooting Checklist before you continue.
2. If the system frequently loses the time and date, replace the battery. The battery is attached to
the system board.
3. Set the new date and time, and reset the configuration parameters using the Setup Utility, if
necessary.
4. Turn off AC power to the HP NetServer, then reboot to see if the date and time was saved.
5. If date and time are still requested, and the battery is good, perform the next procedure.
The configuration information is frequently lost and the battery is good
If the battery is good and you cannot save system configuration, do the following
1. Review the Troubleshooting Checklist before you continue.
2. Configuration information is saved in the CMOS. If you continue to loose configuration
information and the battery is good, or you cannot save the information to the CMOS:
a. If possible, using the configuration utility, save the current configuration to a diskette.
b. Replace the system board.
Verifying Hard Disk Drive Operation
Each Ultra2 hard disk drive module has two LED indicators on its front, one for status and one for activity.
