TOC button
The TOC (transfer of control) button interrupts the system and transfers control from the default device to an auxiliary device. A transfer of control saves the state of the processor in Processor Internal Memory (PIM) and begins execution of recovery software at a nonzero location specified by a special location in Page Zero called MEM_TOC. The TOC code is protected by a checksum.
power cord connector
Plug the workstation’s power cord into the power cord connector to provide AC power to the system.
security loop
The security loop provides a means of locking the left side panel with a padlock or other locking device to prevent unauthorized access. To operate the security loop:
1. Inspect left side panel for proper seating in the mainframe chassis.
2. Push in the retractable pin on the spring loaded square fastener.
3. Insert the locking device through the top and bottom holes of the square fastener.
4. Inspect after locking device is in place to assure that the retractable pin is captured in the side panel insert hole.
The internal components of the workstation is now secured. See Figure 1-7. on page 30.
NOTE A locking device is not supplied with the workstation; the customer must supply a lock to use with the security loop.

USB keyboard
The HP workstation c-class supports USB keyboards. The keyboard shipped with the workstation provides a localized PC-104, PC-105 or HP-JIS-106 compatible input device for USB-equipped PA-RISC workstations and other USB-compatible computers that support the HP-UX operating system. The keyboard includes a captive cable terminated in a USB Style A connector.
The USB keyboard is designed specifically for use with HP workstations. All keyboard models with the exception of the JIS-106 layout may also be compatible with conventional personal computers.
Some applications may expect to use keycodes generated by keys existing on other types of keyboards. Consult the documentation that accompanies each input device for specific information concerning its use.
NOTE HIL and PS/2 devices are not supported by the c-class workstations.
USB hp scroll mouse
The HP scroll mouse (USB) has a left and right button that function the same as most mice. However, it also has a scroll wheel located between the two buttons that allows for vertical scrolling in a window. Note that vertical scrolling will only occur if you are in a window’s vertical scroll bar. This scroll wheel also functions as a middle button when you press down on it. Essentially, the HP scroll mouse is a three-button mouse.
For general information on the various cursor shapes associated with different areas of HP
CDE while using a mouse, see the Using Your HP Workstation document.
hp hub for USB devices
The HP USB hub (part number D6804) provides the ability to connect more than one USB device to the workstation, as well as the ability to extend your USB device’s cable length.
As an example, you may desire to locate the workstation’s keyboard and mouse at a greater distance from your workstation. To accomplish this, connect the HP USB hub to one of the USB connectors on the rear of the system. The keyboard and mouse are then plugged into the USB hub. This is the only acceptable USB hub configuration currently supported by Hewlett-Packard.

product information memory
memory
The main memory for an HP workstation c-class can vary from a minimum of 128 MBytes to a maximum of 2 GBytes. The workstation has eight memory card slots. Currently the c-class workstation supports only 128 MByte and 256 MByte memory DIMM cards in these slots.
CAUTION If memory is installed improperly or it is defective the c-class workstation operating system will not boot-up, and a DIMM error will appear in the LCD.
If an error does occur, reference Chapter 3, “Troubleshooting” for additional information.
memory failures
The HP workstation c-class operating system uses Memory Page Deallocation, a feature that allows the system to provide information to the operating system about memory failures.
You can use the command memrpt with the detail switch to obtain information about the
Memory Page Deallocation Table (PDT) as well as single bit errors logged by the system.
# /usr/sbin/sysdiag Enter
DUI>logtool Enter
LOGTOOL>memrpt detail Enter
The PDT can also be checked using the pdt command in the Service menu of the Boot
Console Handler (Refer to Chapter 6). If you replace a defective DIMM, use the Service
Menu pdt clear command to clear out the PDT.

internal storage configurations
hard disk drive configuration
The SCSI IDs for hard disk drives are hard-wired into the SCA Ultra2 Wide LVD SCSI interfaces in the backplane of the two disk bays within the HP workstation c-class. Hence,
SCSI IDs do not need to be set for the hard disk drives (up to two) installed in these workstations. From top to bottom, the pre-set SCSI IDs for hard disk drives are: 6 and 5.
Similarly, no jumpers are installed at the factory, nor is any jumper installation required at the customer’s site, on either of the hard disk drive models that are supported with the c-class workstations. Both hard disk drive models may be installed into these
workstations. See the section titled “hard disk drive” on page 134 for details on installing
hard disk drives.
NOTE There must ALWAYS be a terminator at both ends of a SCSI bus. This means one internal terminator and one external terminator.
Table 2-1 lists the default device IDs for internal storage devices. These IDs are the default
IDs for each storage device. If an existing device already uses an ID, select an alternate ID.

FRU configurations
The HP workstation c-class supports the 128 MByte DIMMs or the 256 MByte DIMMs. If users install different size memory boards in a single unit, the largest size must be loaded first then the smaller capacity memory boards for maximum performance. For example, load a 256 MByte DIMM in slot 0 and a 128 MByte DIMM in slot 1.
NOTE Users who wish to achieve both maximum performance and maximum future capacity are advised to use 256 MB boards exclusively.
See the section titled “DIMM cards” on page 141 for details on installing memory. Also,
note that there is a label on the floor of the workstation’s interior showing the HP workstation c-class memory loading order.
Use the Boot Console Handler to verify that the workstation recognizes the installed
memory. See “displaying the current memory configuration” on page 175 of this manual.

troubleshooting
This chapter provides information about isolating a failing component, known as a Field
Replaceable Unit (FRU), in the HP workstation c-class.
47
troubleshooting
To troubleshoot a HP workstation c-class, you must be familiar with the HP-UX operating system and be able to start and stop processes. You should also be familiar with the boot
ROM diagnostics, and the Mesa (Support Tools Manager) on-line tests, which we describe in this chapter.
As a super-user who is troubleshooting a HP-UX system, you should be able to shutdown and reboot a system, start and stop processes, and examine error logs. You should also be able to use systems utilities such as ioscan to check device files and configurations, swlist to show loaded patches and software bundles, and SAM to configure and show enabled services and configurations. You should also be familiar with STM, the on-line diagnostics tool. You can view a man page on any of these on-line utilities or commands.
Note any error or status messages, then run the power-up boot ROM diagnostics, known as
Self Test. If the Self Test diagnostics fail, replace the FRU that is indicated. If the tests pass, but you still suspect a problem, run the ISL diagnostics and Mesa (Support Tools
Manager) on-line tests.
For a complete description of using ISL diagnostics and using Mesa (Support Tools
Manager), refer to the website URL: http://wojo.rose.hp.com/

troubleshooting dealing with a boot failure
dealing with a boot failure
To start this workstation from an operating system stored on a device different from the usual boot device, to boot from a different disk, or to boot from another type of device (such as DDS tape drive, an alternate hard disk or CD), see the following situations and examples that use the Boot Console Handler. To access the Boot Console Handler, see
Chapter 6 of this manual.
• To boot from a known device containing a bootable operating system, type the following at the prompt and press Enter :
Main Menu: Enter a command or a menu > boot device where device is the hardware path to the device, specified in Mnemonic Style Notation
For example, to boot an operating system stored on a DDS-format tape in a drive located at “ scsi.1.0
,” go to the Main Menu of the Boot Console Interface and then type the following command at the prompt and press Enter :
Main Menu: Enter a command > boot scsi.1.0
The operating system on the specified device is used to start the workstation.
• To interact with the Initial System Loader (ISL) before booting the workstation, type the following at the prompt and press Enter :
Main Menu: Enter a command or a menu > boot <device>
You are prompted: Interact with ISL (Y or N) > y
Answering yes ( y ) causes the ISL to be loaded from the specified device. After a short time, the following prompt appears on the screen:
ISL>
ISL is the program that actually controls the loading of the operating system. By interacting with ISL, you can choose to load an alternate version of the HP-UX operating system.
For example, if the usual kernel ( /stand/vmunix for HP-UX 10.20) on the root disk
( fwscsi.6.0
) has become corrupted, boot the workstation from the backup kernel
( /stand/vmunix.prev
for HP-UX 10.20) by typing the following at the ISL> prompt and press Enter :
ISL> hpux /stand/vmunix.prev
• To find the location of the bootable operating systems on the various media in the file system, use the search ipl command.
Chapter 3 57
troubleshooting dealing with a boot failure
searching for bootable media
To list all devices that may contain bootable media, go to the Main Menu of the Boot
Console Interface and then type the following at the prompt:
Main Menu: Enter a command or a menu > search ipl
The search may turn up more devices than there are lines on the display. If using a text terminal, you can control the progress of the search from the terminal’s keyboard by performing the following steps:
• To hold the display temporarily, press Ctrl S
• To continue the display, press Ctrl Q
• To halt the search, press Esc
These flow-control commands do not work with a bitmapped display, but such a display can show more than forty lines of text, so they are unnecessary.
To search for devices of just one type that actually contain bootable media, go to the Main
Menu of the Boot Console Interface and then type the following at the prompt:
Main Menu: Enter a command > search ipl device_type where device_type is one of the following:
• fwscsi is the built-in fast, Ultra2 Wide LVD (Low Voltage Differential) SCSI bus.
• scsi is the built-in single-ended SCSI bus.
• lan is all connections to the built-in LAN.
• ide is the built-in CD-ROM drive.
• pci n is an optional SCSI interface in slot number n .
stable storage
Stable Storage is non-volatile memory associated with each PA-RISC processor module.
Stable storage is used by the processor (CPU) to store device path information, the state of the boot flags, HPMC error information, and operating system initialization data.
58 Chapter 3
troubleshooting dealing with a boot failure
boot command notations
The boot command supports the following two notations:
• Mnemonic
• Path number
Type help scsi or help lan for more information on the boot path parameters.
Here are examples of mnemonic notation:
• boot with “no parameters” selects the primary boot path in stable storage.
• boot with the alternate or alt parameters selects the alternate boot path in stable storage.
Here is an example of path number notation:
• boot p1 [Enter] attempts to boot from the second path in a list generated by a previous search command.
supported boot paths
SCSI devices are bootable when connected to the SCSI port on the system. Diskless workstations can only boot from the LAN port on the system board. The workstation can be booted from the CD-ROM for software installation.
ISL environment
The ISL environment provides the means to load the operating system (HP-UX) environment. The ISL environment also provides an off-line platform to execute diagnostic and utility programs from a boot device when HP-UX does not load.
The ISL program is the first program loaded into main memory from an external media
(LAN, disk, or tape) and launched by the initial program loader (IPL) routine during the
Boot Administration environment.
The ISL environment provides the following capabilities:
• Execute user-entered commands to modify boot device paths and boot options in stable storage.
• Run off-line diagnostic programs and utilities.
• Provide automatic booting of the HP-UX operating system after power-on or reset.
The ISL program provides a stand-alone environment for loading off-line diagnostic and utility programs from the LIF directory. The ISL program also provides user commands to configure the boot parameters into Stable Storage.
Chapter 3 59
troubleshooting selftest failures
selftest failures
Chassis codes are the key to debugging selftest errors. If a failure is found during selftest, chassis codes are displayed in the LCD. The procedure for using these codes to debug a failure is as follows:
1. Using Table 3-2., “Chassis Codes for th HP Workstation C-Class,” find the chassis code
listed on the LCD.
2. To get additional information about failures from the Boot Console Handler, use the
Service Menu’s pim , pdt , and ChassisCodes commands.
In the following table, the FRU column shows messages printed on the LCD that refer to system FRUs. Only FLT codes have FRUs associated with them. Some WRN codes are also device specific, especially to IODC calls; for example, 8xxx codes.
TST and INI codes do not necessarily correspond to any FRU. All codes are listed in numeric order.

memory failures
The HP workstation c-class system requires Memory Page Deallocation to be implemented. This feature allows the workstation to provide information to the operating system about memory failures.
The HP-UX operating uses information to map out failing memory areas and continue normal operation. You can use the command memrpt with the detail switch to obtain information about the Memory Page Deallocation Table (PDT) as well as single-bit errors logged by the system.
# /usr/sbin/sysdiag Enter
DUI > logtool Enter
LOGTOOL> memrpt detail Enter
The PDT can also be checked using the pdt command in the Service menu of the Boot
Console Handler (refer to “boot console menus” on page 159).
For allowable memory configurations see Chapter 2 of this manual.

troubleshooting running ODE-based diagnostics
running ODE-based diagnostics
The Offline Diagnostic Environment (ODE) consists of diagnostic modules for testing and verifying system operation. ODE provides all the necessary functions for the user to load specified tests and interact with those tests.
ODE is an ISL utility. To boot ODE:
1. Invoke the ISL environment from the system disk or CD-ROM.
2. Type ode [Ente r ] after the ISL> prompt to invoke ODE from the LIF directory on the system disk. The prompt changes to ODE> .
Not all of the test modules are available on all systems. To see what test modules are available to run on this system, type ls at the ODE> prompt. The available modules include the following:
• wdiag – tests and verifies the basic functionality of the PA-8500 chip. This tool tests the
CPU, cache, TLB and floating point functions.
• memtest – tests and verifies the memory arrays. If an error is detected, the diagnostic reports the memory card and its slot number that needs replacement. It also, provides a map of the memory configuration so that the user can identify the types of memory and its slot location.
• mapper – identifies the configuration of HPPA systems. It displays path, identification, and revision information of I/O components, configuration of memory controllers, processors, co-processors, cache, and TLB, as well as processor board component revisions and values of various HPPA system identifiers, revisions and capabilities.
• astrodiag – tests and verifies the basic functionality of the Astro memory/IO controller chip.
• siodiag – tests and verifies the functionality of the super IO multifunction IO chip, including serial, parallel, USB, etc.
For further information on the various ODE commands and a complete listing of the command set, type help [Enter ] at the ODE> prompt or at the prompt of one of the test modules.

FRU removal and replacement
FRU removal and replacement
The procedures in this section describe how to remove field replaceable units (FRUs).
Observe any notices and prerequisites before removing a FRU. Replacement is the reverse of removal, unless noted.
Before performing these procedures, observe the following precautions:
Step 1. Power off the system, the monitor, and any peripheral devices.
NOTE There is no need to manually shutdown the HP-UX operating system on the workstation before switching it off. When the front panel power switch is pressed to off, the workstation automatically shuts down the operating system before terminating the power. Wait for the system to completely shutdown and power off before disconnecting the power cord.
CAUTION Unplugging the power cord while HP-UX is running can damage the system files. Do not remove the left side panel before powering down the workstation.
Remember that the left side panel is integral to the power supply safety interlock.
Step 2. Unplug the workstation power cord and the power cord of any peripheral devices from AC wall outlets.
Step 3. Unplug the system unit power cord from the AC input connector.
Step 4. Disconnect any external cables from the connectors on the front and rear of the system unit.
Step 5. Attach a static-grounding wrist strap to your wrist and a location on the system chassis that is bare metal. Attach the sticky end of the wrist strap to bare metal on the rear panel of the workstation.
Step 6. Lay the workstation on a flat stable surface, such as a table top or floor. To protect against scratches, remove miscellaneous debris and preferably use an ESD mat to cushion the workstation.
CAUTION Follow normal ESD, anti-static precautions when handling the workstation or any of its components. Failure to do so can cause component degradation or failure.
Step 7. If installed, remove any locking device from the security loop on the rear of the system unit. To access the storage media, the front panel security lock must be in the unlock position.

3. Plug in the system unit power cord, and power on the system.
left side panel of the system unit
This section explains how to open and close the left side panel of the system unit. This side panel will have to be opened whenever you need access to the internal components of the workstation.
opening the left side panel of the system unit
Perform these steps to open the left side panel.
WARNING If you remove the left side panel while the workstation is running, the safety interlock switch will power down the workstation. Be aware that cutting off power to the workstation via the safety interlock does not perform a clean shutdown of the workstation.
1. Turn the computer around so the rear is facing you. On the right edge of the computer,

hard disk drive
This section describes installation and removal of hard disk drives in the HP workstation c-class.The first subsection details how to install a hard drive, the second subsection details how to remove a hard disk drive and the final subsection describes how to configure the hard disk after it is installed.
The HP workstation c-class may have a maximum of two hard drives. The hard drive that came with the workstation was set to SCSI ID 6. If adding a second hard disk drive, the second hard disk drive will use SCSI ID 5. Note that the two slots for the hard disk drives have SCSI ID numbers 5 and 6 preassigned to them. You will not be able to change the
SCSI ID numbers.
NOTE Do not use SCSI ID 7 for any of the internal or external disk drives. The host
SCSI controller uses SCSI ID 7.
Installing a Hard Disk Drive
NOTE If you are installing a new hard disk drive, the slotted pan screws for attaching the drive in the carrier are stored on the carrier rails. Also, see the section titled “hard disk drive configuration” in Chapter 2 in this manual.
1. Open the front panel of the workstation, refer to the section “opening the system unit front panel.” In the front lower-right corner of the workstation, there are two hard drive
slots. The slot on the far right is the one discussed in this section. See Figure 4-48.

boot console handler booting the workstation
booting the workstation
In general the HP workstation c-class is started by the power switch and HP-UX boots automatically. However, you may not always want the usual sequence to occur.
For example, you may want to start the workstation from an operating system that is stored on a device that is different from the usual boot device. If the normal operating system kernel or the disk on which it resides becomes damaged or unusable, you may wish to boot from a different disk or perhaps another type of device, such as a CD drive.
Here are some possible booting scenarios you may encounter:
• If you know which device you want to boot from, and you know that it contains a bootable operating system, follow the directions in “accessing the boot console handler” earlier in this chapter, and then type the following at the prompt and press Enter :
Main Menu: Enter command > boot device where device is the hardware path to the device, specified in Mnemonic Style Notation.
For example, if you wish to boot an operating system that is stored on a DDS-format tape drive that is located at the hardware path scsi.1.0, you would type the following command at the prompt and press Enter :
Main Menu: Enter command > boot scsi.1.0
• If you do not know which device you want to boot from, then type the following at the prompt and press Enter :
Main Menu: Enter command > search
A message similar to the following will be displayed:
Path Number Device Path
--------------------------
P0 IDE
P1 FWSCSI.6.0
Device Type
------------------
TEAC CD-532E-B
SEAGATE ST39102LC
At the prompt, you might type the following and press Enter :
Main Menu: Enter command > boot P1
Note that the operating system on the specified device ( P1 ) is used to boot the workstation (also, see the section “searching for bootable media”).
• If you wish to interact with the Initial System Loader (ISL) before booting the workstation, follow the directions in “accessing the boot console handler” earlier in this chapter, and then type the following at the prompt and press Enter :
Main Menu: Enter command > boot device
The following prompt will appear:
Interact with ISL (Y, N, Q) >
164 Chapter 6
boot console handler booting the workstation
Answering yes ( Y ) causes the ISL to be loaded from the specified device. After a short time, the following prompt appears on your screen:
ISL>
ISL is the program that actually controls the loading of the operating system. By interacting with ISL, you can choose to load an alternate version of the HP-UX operating system. If you do not want to interact with ISL, you must enter no ( N ).
For example, if the usual kernel ( /stand/vmunix ) on your root disk ( fwscsi.6.0
) has become corrupted, and you wish to boot your computer from the backup kernel
( /stand/vmunix.prev
), type the following at the ISL> prompt and press Enter :
ISL> hpux /stand/vmunix.prev
• If you do not know which media in your file systems have bootable operating systems, you can find them with the search ipl command. See the subsequent section
“searching for bootable media” on page 166.
Chapter 6 165
boot console handler searching for bootable media
searching for bootable media
To list devices that contain bootable media, follow the directions in “accessing the boot console handler” earlier in this chapter, and then type the following at the prompt and press Enter :
Main Menu: Enter command > search ipl
The search command searches all buses. The search may turn up more devices than there are lines on your display. If you are using a text terminal, you may control the progress of the search from your terminal’s keyboard by performing the following steps:
• To hold the display temporarily, press Ctrl S
• To continue the display, press Ctrl Q
• To halt the search, press any other key
These flow-control commands do not work with a bit-mapped display, but such a display can show more than forty lines of text, so you are unlikely to need them.

boot console handler setting the auto boot and auto search flags
setting the auto boot and auto search flags
The auto boot and auto search flags are variables stored in your workstation’s nonvolatile memory. (Nonvolatile memory retains its contents even after power is turned off.) If you reset these flags to a new value, the change takes effect the next time you reboot the workstation.
The auto boot flag boots the operating system whenever the workstation is turned on.
To examine the state of the auto boot and auto search flags, type the following at the prompt and press Enter :
Configuration Menu: Enter command> auto
If auto boot is set to on, your workstation automatically attempts to boot the operating system when turned on. If auto boot is set to off, your workstation enters the boot administration mode of the Boot Console Handler.
The state of the auto search flag determines how your workstation seeks a boot device during autoboot. If auto search is set to on, your workstation will search for other boot devices if the primary boot device is not available. If auto search is off, your workstation will default to the boot administration mode if it can’t see the primary boot device.
To change the state of the auto boot or auto search flags, type the following at the prompt and press Enter :
Config Menu: Enter command> auto boot state or
Config Menu: Enter command> auto search state where state is on or off .
Auto search searches for devices in the following order:

boot console handler
ISL environment
ISL environment
The ISL environment provides the means to load the operating system (HP-UX) environment. The ISL environment also provides an offline platform to execute optional diagnostic and utility programs from a boot device when HP-UX does not load.
The ISL program is the first program loaded into main memory from an external medium
(LAN, disk, or tape) and launched by the initial program loader (IPL) routine from the
Boot Administration environment.
The ISL environment provides the following capabilities:
• Execute user-entered commands to modify boot device paths and boot options in stable storage.
• Run offline diagnostic programs and utilities
• Provide automatic booting of the HP-UX operating system after power-on or reset
invoking ISL from the boot console handler
Perform the following steps to invoke ISL from the boot console handler:
Step 1. Follow the directions in “accessing the boot console handler” on page 158, and
then type the following at the prompt and press Enter :
Main Menu: Enter command > boot device
You are prompted:
Interact with ISL (Y, N, or Q) > y
Step 2. Answering yes ( y ) causes the ISL to be loaded from the specified device. After a short time, the following prompt appears on your screen:
ISL>
ISL is the program that actually controls the loading of the operating system. By interacting with ISL, you can choose to load an alternate version of the HP-UX operating system.
For example, if the usual kernel ( /stand/vmunix ) on your root disk ( fwscsi.6.0
) has become corrupted, and you wish to boot the workstation from the backup kernel ( /stand/vmunix.prev
), type the following at the ISL> prompt and press
Enter :
ISL> hpux /stand/vmunix.prev
ISL user commands
The following commands available in the ISL environment allow you to display and modify the boot characteristics of the system.
• help - lists ISL command menu and available utilities.
Chapter 6 185
boot console handler
ISL environment
• display - displays the boot and console paths in Stable Storage and the current setting of the ISL Boot Flags.
• primpath - modifies the primary boot path entry in Stable Storage. The entry in Stable
Storage for the primary boot device begins at byte address 0 and ends at byte address
31.
• altpath - modifies the alternate boot path entry in Stable Storage. The entry for the alternate boot device begins at byte address 128 and ends at 159.
• conspath - modifies the console path entry in Stable Storage. The console device begins at byte address 96 and ends at byte address 127. The entry for the keyboard and mouse devices begins at byte address 160 and ends at 191.
• listautofl or lsautofl - lists the contents of the (HP-UX) autoboot file.
• support - boots the Support Tape from the boot device.
• readss - displays 4 bytes (one word) from Stable Storage. The readss command requires a decimal number between 0 and 255 to address four bytes in Stable Storage.

boot console handler obtaining and updating system firmware
obtaining and updating system firmware
To update a system’s firmware, the firmware patch must be obtained from the patch server website at http://us-external_support.hp.com or http://europe-external_support.hp.com.
The patch file is a combined shar’ed file that contains an ASCII cataloging file, a readme type ASCII file, and the firmware LIF binary file. The LIF volume is bootable to ODE which in turns runs the UPDATER utility to download the firmware image files.
Creating the Firmware Update Tape (on any HP-UX system)
Step 1. Verify the checksum of the file ".FRM" using the " sum " command. Results of the command should be equal to the "sum" value as documented in the header of this document.
Step 2. Use the "dd" command to copy the file " CXXXXXXX.FRM
" to tape, as follows: dd if=CXXXXXX.FRM of=/dev/rmt/0m bs=2k
(device path dependent)
NOTE: Blocksize ( bs ) must be = 2k
Identify Current Version of Firmware (on system to be updated)
Step 1. Re-boot your system and do the following: a. Interrupt the boot process and from the Boot Console Handler prompt, type
< information > and press [return].
b. Identify your firmware revision. The last two digits in the patch name indicate the revision. In this case, X.X
is the revision. If the revision on your system is equal to or higher than X.X
, do not proceed with the update.
to install the firmware update
The following are the directions from the readme file that are the firmware updating instructions for a DAT tape drive:
Step 1. Install the tape you have just created into your tape drive.
Step 2. Shutdown your system via the power switch and power back on, or execute the reboot command resetting your system.
Step 3. When the display reads "Searching for a system to boot" press [escape]. At the
BOOT ADMIN prompt, type search and press Enter or Return to identify the tape device path.
Step 4. Boot from the appropriate boot path. (You must boot from the device that contains the firmware update tape.) When the display reads “ Interact with
IPL (Y, N, Q)> ”, type N and press Enter .
Chapter 6 187
boot console handler obtaining and updating system firmware
NOTE This process is automatic and requires no interaction until directed to do so.
Please do not interrupt the process. The load process will take about 2 minutes.
Step 5. A warning message will be issued, followed by " Continue ([y]/n)?
” type y and press Enter if you wish to continue. Be sure the image on the tape is a newer version than that on your system before proceeding.
After several screens go by, you will be informed as to what firmware image is on your system and which image is on the tape. You will be asked if you want to proceed. " Continue ([y]/n)?
"
If the image on the tape has a higher revision number, type < y > and press Enter .
If no, then type n and press Enter .
NOTE FROM THIS POINT FORWARD, THIS PROCESS CANNOT BE
INTERRUPTED UNTIL COMPLETION. INTERRUPTING THIS PROCESS
WILL CAUSE YOUR SYSTEM TO BE INOPERATIVE.
DURING THE EXECUTION OF THIS UPDATE, THE FIRMWARE FONTS
FILE WILL BE RE-WRITTEN. IF THESE ARE NEW FONTS, YOU WILL
NOT SEE ANY TEXT WRITTEN TO THE SCREEN AFTER THE
MESSAGE.
You will see 2 carriage returns and 2 line feeds and then the display will remain the same. In approximately 40 seconds the system will automatically re-boot. If it doesn’t, the update has failed. Attempt to run the update again from Step 2. If it still fails, or you cannot get to the Boot Administration prompt, call your HP
Service Representative.
The system will continue the normal boot process from the default primary path.

SCSI Bus Differences
SCSI Bus Differences
A Small Computer Systems Interface (SCSI) bus is an IEEE standard bus for connecting your workstation to internal and external devices (SCSI devices) running at different speeds. There may be one device connected to the external SCSI port or more than one device may be daisy chained to a single external SCSI port. Examples of SCSI devices are
4-mm DDS-format tape drives and hard disk drives.
There are two types of SCSI buses available with this workstation—an Ultra Narrow
Single-Ended SCSI bus (NSE SCSI), and an Ultra2 Wide Low-Voltage Differential SCSI bus (LVD SCSI). The following table shows the specification differences between these
SCSI buses.
CAUTION Currently Hewlett-Packard does not support mixing Ultra Narrow
Single-Ended and Ultra2 Wide LVD devices on any one bus type.

SCSI restrictions
This section describes the SCSI restrictions that apply to your workstation in the following areas:
• Cables
• Terminators
• Number of Devices Per SCSI Bus
• Considerations for Selecting SCSI Devices
NOTE The Ultra Narrow, single-ended SCSI bus supports only 7 devices because address 7 is reserved by the system. The Ultra2 Wide, Low-Voltage
Differential SCSI bus supports 15 devices because address 7 is reserved by the system.

SCSI restrictions
terminators
The terminators for Ultra2 Wide Low-Voltage Differential SCSI (LVD SCSI) and Ultra
Narrow Single-Ended SCSI (NSE SCSI) are different. The NSE SCSI terminator has 50 pins and will fit on an NSE SCSI connector. The LVD SCSI terminator has 68 pins and will fit on a LVD SCSI connector. Note that these SCSI terminators were shipped with your system.
CAUTION It is necessary to put a terminator on unused SCSI connectors on the back panel of the system. However, if SCSI devices are attached to the SCSI bus via these connectors, the external device connected to the SCSI bus must be terminated with a SCSI terminator. If you do not already have the SCSI terminators, you must order terminator A1658-63012 (for the 50-pin terminator; NSE SCSI) or A4986-63008 (for the 68-pin terminator; LVD
SCSI) from Hewlett-Packard.
number of devices per SCSI bus
The number of SCSI devices per bus is limited (see Table B-1. on page 203). Before adding
another SCSI device, determine if the system can support the additional device.
This workstation offers the following types of SCSI buses, each with their own configuration constraints:
• Ultra Narrow Single-Ended SCSI bus
• Ultra2 Wide Low-Voltage Differential SCSI bus
considerations for selecting SCSI devices
SCSI devices supported by the Hewlett-Packard Company for the Ultra Narrow
Single-Ended (NSE) and Ultra2 Wide Low-Voltage Differential (LVD) SCSI buses have been qualified as SCSI devices which meet NSE and LVD specifications. Contact the local
HP sales representative for a current list of SCSI devices supported by HP for use on the
Ultra Narrow Single-Ended and Ultra2 Wide Low-Voltage Differential SCSI buses.
If devices other than those supported by HP are connected to the Ultra Narrow
Single-Ended or the Ultra2 Wide Low-Voltage Differential SCSI bus on this system, they must adhere to cabling, termination and bus length restrictions discussed in this chapter to assure functionality of the SCSI busses.
Because Ultra2 Wide Low-Voltage Differential SCSI is a relatively new technology, there can be products which are advertised as LVD compliant, but may not meet LVD specifications. Therefore, additional caution must be exercised when choosing Ultra2 Wide
Low-Voltage Differential SCSI bus on this system. For example, the cabling inside one of these devices in question may not have a differential impedance between 110 ohms and
135 ohms and it may be constructed in a way such that the device has considerable crosstalk on critical signals, such as Reset, Select and Busy. Failure to strictly adhere to the Ultra2 Wide Low-Voltage Differential SCSI bus specifications will impact the performance of the LVD bus. The Ultra2 Wide Low-Voltage Differential interface is a much
206 Appendix B
SCSI connections
SCSI restrictions higher performance SCSI bus than previous SCSI buses and is more sensitive to adherence to the electrical specifications.
Low-voltage differential signaling specifications are described in the SCSI Parallel
Interface-2 (SPI-2) document and in the Electrical Characteristics of Low Voltage
Differential Signaling (LVDS) Interface Circuits TIA/EIA-644 document. Both of these documents can be obtained from:

SCSI bus length constraints
SCSI bus length constraints
This section discusses SCSI bus length constraints for the Ultra Narrow Single-Ended
SCSI bus and the Ultra2 Wide Low-Voltage Differential SCSI bus.
Ultra narrow single-ended SCSI bus length
The maximum cable length for a Ultra Narrow Single-Ended SCSI bus is 3 meters. The
HP workstation c-class uses a negligible amount of this maximum cable length.
NOTE When calculating the total Ultra Narrow Single-Ended SCSI cable/bus/trace length used externally, remember to account for cables connecting external devices together as well as the bus length internal to those devices.
There are two total cable length specifications that apply to the Ultra Narrow
Single-Ended SCSI bus on the workstation. Note that these specifications are based on the requirement that the SCSI device being connected to the NSE SCSI bus does not exceed the maximum capacitance of 25 picofarads (pF). Check with the vendor of the SCSI device for the maximum capacitance specification.
The total cable length specifications are described below:
• For a total of one to four devices being connected to the NSE SCSI bus the total length of cable used should not exceed 3.0 meters
• For a total of five to eight devices being connected to the NSE SCSI bus the total length of cable used should not exceed 1.5 meters.
NOTE Remember that the workstation is counted as one of the total device, and the internal length of its cabling is 0.15 meters. This length needs to be considered in your total cable length determination.
Ultra2 wide low-voltage differential SCSI bus length
The maximum cable length for a Ultra Wide Low-Voltage Differential SCSI bus is 12 meters. The HP workstation c-class uses 1 meter of this maximum cable length internally.
This means that up to 11 meters of cable can be used for connecting external Ultra2 Wide
Low-Voltage Differential SCSI devices to this workstation.
208 Appendix B
SCSI connections
SCSI bus length constraints
NOTE When calculating the total Ultra2 Wide Low-Voltage Differential SCSI cable/bus/trace length used externally, remember to account for cables connecting external devices together as well as the bus length internal to those devices.

SCSI connections assigning SCSI device IDs
assigning SCSI device IDs
Before assigning a SCSI device ID to your drive, you need to check the existing SCSI device IDs. To determine which SCSI device IDs are available for your device, use the ioscan command in a terminal window:
1. At a command line prompt, enter the following:
/usr/sbin/ioscan -f
After a few moments, the ioscan utility lists all of the SCSI I/O devices it could find. The list appears similar to the following:

SCSI connections assigning SCSI device IDs
assigning Ultra narrow single-ended SCSI device IDs
You can determine which Ultra Narrow Single-Ended SCSI (NSE SCSI) devices are currently in use by reviewing the output from the ioscan command discussed above and looking under the “H/W Path” heading. The entry 10/0/15/0 is the built-in Ultra Narrow
Single-Ended SCSI bus. For devices connected to the built-in Ultra Narrow Single-Ended
SCSI bus, such as disks, the number between the two decimals and after the third “/” in the hardware path specifies the SCSI ID for that device. For example, a hardware path of
10/0/15/0.2.0
specifies a NSE SCSI device at SCSI ID 2.
Here is the break down of the hardware path:
SCSI device 10/0/15/ 0.2.0
NSE SCSI 10/0/15/ 0 .2.0
SCSI ID 2 10/0/15/0.

CAUTION Do not use SCSI device ID 7 for any device. It is reserved for the built-in SCSI bus controller.
assigning Ultra2 wide low-voltage differential SCSI device IDs
You can determine which Ultra2 Wide Low-Voltage Differential SCSI (LVD SCSI) devices are currently in use by reviewing the output from the ioscan command discussed above and looking under the “H/W Path” heading. The entry 10/0/15/1 is the built-in Ultra2
Wide Low-Voltage Differential SCSI bus. For devices connected to the built-in Ultra2 Wide
Low-Voltage Differential SCSI bus, such as disks, the number between the two decimals and after the third “ / ” in the hardware path specifies the SCSI ID for that device. For example, a hardware path of 10/0/15/1.5.0
specifies a LVD SCSI device at SCSI ID 5.
Here is the break down of the hardware path:
SCSI device 10/0/15/1.5.0
LVD SCSI 10/0/15/1.5.0
SCSI ID 5 10/0/15/1.5.0
CAUTION Do not use SCSI device ID 7 for any device. It is reserved for the built-in SCSI bus controller.

Glossary
drag To move the mouse (and hence the pointer on the screen) while holding down one or more of its buttons. This process specifies two separate locations on the screen for those operations that require two: the location when the mouse button is pressed, and the location when it is released. This is used, for example, to initiate a file-copy by pressing the mouse button on the file to be copied, dragging the file’s icon to the destination window, and releasing the mouse button there. Another common using of dragging is to specify the upper-left and lower-right corners of a new window or similar rectangle See also drop.
