2 System Information
Boot Priority
Some boards have preferred slot locations. Consider the boot order when choosing the accessory board slot in which to install the accessory board.
This is the default boot priority for the LH 6000/6000r:
1. IDE CD-ROM drive with a bootable CD-ROM
2. Flexible disk drive with a bootable flexible disk
3. HP NetRAID controller or integrated Embedded SCSI controller
4. PCI boards in slots in the following order: 8, 7, 6, 5, 4, 3, 2, and 1
Change this boot order using the Setup utility.
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
Unless otherwise noted, the following features apply to all models. Some features are factory installed; others are optional.
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.

Add paired DIMMs of these sizes:
◊ 128 MB
◊ 256 MB
◊ 512 MB
◊ 1 GB
Memory of equal size must be added in pairs.
You can mix DIMM sizes. For example, you may place a 1 GB DIMM pair next to a 128 MB
DIMM pair.
Add paired memory in any order to the eight slots.
21
Chapter 2 System Information l
Maximum configuration is 8 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.
The installation procedure is the same for the rack-mount and the pedestal HP NetServers once you gain access to the system board assembly. While you can perform memory installation in the rack or in the pedestal, it is recommended that you remove the system board assembly in order to install components. If you install memory without removing the system board assembly, the DIMM slots region of the system board is accessible when the bottom cover of the LH 6000r is removed and the left cover of the LH 6000 is removed.
CAUTION Wear a wrist-strap and use a static-dissipating work surface connected to the chassis when handling components. Ensure the metal of the wrist strap contacts your skin.
Mass Storage Guidelines
This HP NetServer has a flexible mass storage system. You can install up to six hot-swap devices in the primary hot-swap mass storage cage and you can install an additional six hot-swap devices in the optional, secondary cage.
Flexible disk drive
CD-ROM drive
Non-hot-swap drive shelves
Secondary hot- swap cage
Primary hot-swap cage
The mass storage system includes several standard pre-installed devices:
• A flexible disk drive is installed in Shelf 1.
• An IDE CD-ROM drive is installed in Shelf 2.
• A single hot-swap Ultra-2 SCSI hard disk drive is installed in the primary hot-swap mass storage cage.
The HP NetServers support two classes of mass storage devices:
22
Chapter 2 System Information
• Non-hot-swap, single-ended SCSI devices installed in the two empty trays adjacent to the CD-
ROM drive
• Hot-swap Ultra-2 SCSI hard disk drives installed in the hot-swap mass storage cages
Use only high-performance, Ultra-2, hot-swap drives in the integral hot-swap mass storage cages.
You can add any Ultra/Wide, single-ended SCSI device in the non-hot-swap shelves, such as a removable hard disk or a tape backup drive. This table lists supported SCSI devices:
Location
Hot-swap Mass Storage
Shelves
Non-Hot-Swap Shelves
Drive Type
9.1, 18.2 or 36 GB, Ultra-2, 7200 or 10000 rpm drives (up to 35W)
9.1 or 18.2 GB Ultra/Wide or Single-Ended SCSI Drives, 7200 or 10000 rpm drives
DAT backup systems with SCSI DDS3, or DLT Tape Drives
Accessory Board Guidelines
To install accessory boards, during initial installations, into the I/O board, perform the following procedures.
The I/O board is under the top cover of the LH 6000r and under the left cover of the LH 6000.
l Use the respective NOS software utility to
◊ Ensure the correct software drivers for the PCI board are loaded
◊ Verify correct operation
◊ Shut down power to hot plug slots
CAUTION Do not attempt to install or remove non-hot plug PCI boards with the HP NetServer in any kind of sleep state, or a system crash or hang may occur.
l l l l l l
Slots 1, 2, 3, and 4 are non-hot plug; slots 5, 6, 7, and 8 are hot plug.
For optimal performance, add PCI boards to slots 7 and 8, which at 66 MHz and 64 bit, are the fastest.
Consider the boot priority prior to installing accessory boards, but after configuring the HP
NetServer.
Some accessory board outputs may exceed U.S. National Electrical code (NFPA 70) Class 2 or power source limits and must use appropriate interconnecting cabling in accordance with the
National Electrical Code. (All Hewlett Packard boards comply with Class 2.)
You can configure the HP NetServer to boot from a PCI-based DAC inserted into a PCI slot.
Use the Symbios Configuration Utility to select a different PCI slot when scanning for boot devices.
Slots 7 and 8 accept universal boards. Universal boards automatically switch to accept power from a +5.0 or +3.3 VDC.
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.
23
Chapter 2 System Information
NOTE Hot Removal or online deletion of an adapter board and reconfiguring of that adapter from the HP NetServer is not supported.
Refer to the PCI Hot Plug Replacement procedures in HP NetServer Navigator CD-ROM for the NOS you are using.
Online Replacement, Hot Swapping, of a PCI Adapter
NOTE You can Hot Swap an adapter only if it is the passive adapter, or inactive adapter of a fault-tolerant pair.
For more current PCI Hot Plug information and PCI Hot Plug drivers, go to: http://www.hp.com/cposupport/
Select your product and download the latest software. PCI hot plug drivers are in the SCSI section.
Remote Control (Top Tools) Board
The HP Remote Control board supports HP TopTools software and comes installed from the factory in PCI slot 2, due to its boot order (Bus 5) and a required cable connection to the I/O board. The I
HP TopTools Remote Control card is inserted into connector J1F1 on the I/O board.

HP NetRAID Guidelines
This HP NetServer contains an embedded dual-channel RAID controller, which puts the power of the HP
NetRAID series of disk array controllers in the HP NetServer.
HP NetRAID technology lets you link multiple hard disk drives together to provide faster access and/or increased data reliability. With the embedded RAID controller, you can configure your linked drives as RAID
(Redundant Array of Independent Disks).
Disk drives in the hot-swap mass storage cage may be used as either standard mass storage, or configured together as a RAID array.
This HP NetServer is shipped with SCSI A channel enabled as a RAID channel, and the included hot-swap drive is not configured. You can either disable SCSI A channel as a RAID channel, or configure the drive(s) in the hot-swap cage as a RAID array.
To disable SCSI A channel:
• Exclude SCSI A channel from the embedded RAID controller, as follows:
1. Restart the HP NetServer.
2. When you see the message "Press [F2] to enter SETUP" on the monitor, press the [F2] function key.
3. When the Setup Utility menu appears, use the up and down arrow keys to highlight
"Included SCSI A Channel Yes]."
4. Use the +/- keys to change it to "Included SCSI A Channel [No]."
5. Press the F10 function key to save and exit.
6. Answer "Yes" to the question, "Save configuration and exit now?" The HP NetServer will start up again, and HP Navigator will restart.

4 Diagnostics
Diagnostic Tests
When the server boots, a series of tests are displayed on the screen. The number of tests displayed depends on the configuration of the server. The following are the kinds of errors a user might get with the HP
NetServer.
• Built-in diagnostic Error Messages.
• BIOS and other error messages. These are errors detected by the system BIOS outside the built-in diagnostics or application errors.
• Beep Codes when errors cannot be viewed on the screen.
To see the Power On Self-Tests (POST):
• The HP NetServer must be functionally able to run the diagnostics.
• The video subsystem must be functional.
• The keyboard must be functional.
NOTE BIOS ROM version number is displayed on the monitor screen during power-up.
Diagnostics Description
The diagnostics (Power-On Self-Test "POST") run automatically each time the server is powered on. These diagnostics, which reside in the BIOS ROM, isolate server-related logic failures and indicate the board or component that needs to be replaced, as indicated by the Error Messages. Most server hardware failures will be accurately isolated by the diagnostic
Go to "View System Error", displayed on the bottom of the boot screen, for an explanation of each test.
You see a list of the errors that occurred and suggestions on how to resolve them. Use the Setup utility
(press F2 during the boot process) to make any changes to the configuration.
WARNING You should always turn off the power and disconnect the power cords to the server before attempting to remove the cover and touch the internal components. Failing to do so can expose you to electric shock and the server's components to damage.
The power switch does NOT turn off standby power, so disconnect the power cords to turn off standby power.
CAUTION Do not operate the HP NetServer with any of its covers off for more than 60 minutes.
Otherwise, overheating can damage processors, boards, and mass storage devices.
43
Chapter 4 Diagnostics
HP NetServer DiagTools
The purpose of hardware diagnostic software is to provide tools for checking hardware problems. By design, diagnostic software executes simple tests of each hardware component in turn. Usually, such 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 CD-ROM .
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 HP NetServer components, and a menu of advanced tests is available for in-depth testing.
DiagTools has the ability to test the following components: l system board l processors l memory modules l hard disk drives l l flexible disk drives serial ports l l keyboards parallel ports l video monitor l
CD-ROM drives
DiagTools is an off-line diagnostic tests. 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 perform 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
44
Chapter 4 Diagnostics
• 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 list of tasks remotely.
About Error Messages
A hexadecimal number designates each error message reported by DiagTools; a short note on the type of error; and a list of one or more steps the user can take in response. When you run a test, it exercises many aspects of the hardware, so the number of possible error messages exceeds 300. Most of these are encountered rarely, if ever.
Error codes can be viewed on line from the DiagTools User menu within the advanced series of tests, or you can refer to Chapter 3 of the HP NetServer DiagTools Error Reference and User Guide.
Advantages and Limitations of Hardware Diagnostics
Off-line diagnostic software is useful in making sure that hardware 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 Menu
The Event Log menu has information about current and resolved events. The menu provides a list of all events currently in the log. These may be errors, or normal system events like a system boot.
NOTE You can view system events in the status screen and in the Event Log Report Utility in NetServer Utilities on Navigator. The details may differ slightly.
1. Select Event Log from the Main Menu.
The first two lines of the log appear on the HP NetServer's front panel display:
****Event Log****
>008^ POWER Unit
2. Use the arrow buttons to see the complete list.
This is a sample event log:
****EventLog****
>008^ POWER Unit
>007^ TempError
>006 CPU Failure
>005 POWER Unit
>004 Volt Error
>003 CPU Failure
45
Chapter 4 Diagnostics
>002^ POWER Unit

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:

HP NetServer Assistant. HP NetServer Assistant (NSA) is a customizable software toolset that helps monitor and manage servers over the network from an HP OpenView console.
The NSA software has a server part and a management console, or client, part.
TopTools. HP TopTools provides a set of web-based management tools you can use to maintain and control your HP NetServers running Microsoft Windows NT, Novell
NetWare/IntranetWare, or SCO UNIX.
• Always change one component—and only one component—at a time.
• Verify the error.
Check for any general problems:
1. Check that all cables and power cords are firmly plugged into the correct receptacles.
2. Check that all equipment connected to the HP NetServer is turned on.
3. Verify that power is available and is within specification.
4. Check that the HP NetServer is configured correctly in the Setup Utility by pressing [F2] during the boot process or by booting the HP NetServer Navigator CD-ROM.
5. If the server still doesn't work, turn off the monitor, the server, and all external devices. Note the location of all power cords and other cables before unplugging them. Then: a. Remove the cover.
b. Check that all accessory boards are firmly seated in their slots.
61
Chapter 5 Troubleshooting c. Ensure that all mass storage power and flat cables are securely connected.
d. To verify that switches and jumpers on mass storage devices and boards are properly set, see the setup instructions in the mass storage device's manual.
6. Reconnect all cables.
7. Turn on the monitor.
8. Turn on the HP NetServer.
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
62
Chapter 5 Troubleshooting
• 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.
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.
63
Chapter 5 Troubleshooting 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.
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.

Network Interface Card Problems
See the appropriate Network Interface Card documentation.
Symptoms:
The adapter can't connect to the network.
67
Chapter 5 Troubleshooting
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:
◊◊◊◊ AC power cords from AC source outlet to server.
◊◊◊◊ DC Power supply cables to all HP NetServer PCBs
◊◊◊◊ 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:
68
Chapter 5 Troubleshooting 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
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.
69
Chapter 5 Troubleshooting
◊◊◊◊ 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.
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.
70
Chapter 5 Troubleshooting
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].
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.
71
Chapter 5 Troubleshooting
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 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.
72
Chapter 5 Troubleshooting
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.
If you installed a video board and are not using the built-in video system, go to Step 12.
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:
73
Chapter 5 Troubleshooting 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.

Monitor Notes:
◊◊◊◊
◊◊◊◊
◊◊◊◊
◊◊◊◊
When most EGA and VGA monitors are disconnected from the video connector, if the monitor is working, the screen is white.
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.

Chapter 5 Troubleshooting
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.
