CAUTION This workstation is designated for two-person lifting. It weighs

approximately 36 to 49 pounds (16 to 22 kg), depending on the conﬁguration. Do not attempt to lift it by yourself, or injury may result.

Power Switch

This switch turns the system on and off.When you turn your workstation off, the operating system automatically executes the shutdown -q command. This prevents any damage to programs and data on your system disk. Turning the power switch back on again automatically boots up the HP-UX operating system if your system has been conﬁgured to auto boot.

Front Panel Components

Thumbscrew on the Front Panel

There is one captive thumbscrew near the center of the front panel. Loosening and pulling toward you with this screw allows the top panel to be removed. The top panel must be in place or the system will not power up.

Between the LCD panel and the CD ROM drive, there is a threaded hole for an optional locking screw. The locking screw is included in the bag of miscellaneous parts which comes with the workstation. This locking screw allows the user to protect his/her workstation form unwanted entry.

System LCD

The Liquid Crystal Display (LCD) indicator is located on the front panel. The LCD has two 16 characters lines. The LCD displays messages about the state of the system, including chassis codes. The symbols in Figure 1-3 appear in the LCD if you have the HP-UX 11.0 or 11i operating system booted on your system. They represent the different system activities.

Internal Storage Devices

The J6700 workstations support the following internal storage devices, which are also located on the front panel, under the bezel:

• Up to two hot-pluggable, Low-Voltage Differential (LVD) hard disk drives

• One ATAPI (IDE) Slim-Line CD drive (optional) The following subsections describe these internal storage devices.

Hard Disk Drive(s)

The J6700 workstations can support up to two hot-pluggable, Low-Voltage Differential (LVD) hard disk drives. These hard disk drives are 3.5-inch form factor, 10K RPM devices which connect to Ultra2 Wide LVD (Low Voltage Differential) SCSI interfaces on the disk bay backplane. The hard disk drive bays are located on the lower left side of the front panel, below the CD ROM drive. See Figure 1-1.

The two hard disk drive models currently supported are:

• 18 GB LVD 10K RPM disk drive (Product Number A4998A)

• 36 GB LVD 10K RPM disk drive (Product Number A6013A)

NOTE The ability to hot plug the hard disk drive(s) requires MirrorDisk/UX

(Product Number B2491BA on HP-UX 11.0 ACE 1199 or HP-UX 11i ACE

0601).

The Hot-Plug Process

The physical aspect of inserting and removing a disk drive is discussed in the document that comes with the drive. However, the operating system must be prepared for the insertion or removal of a disk, or unexpected and harmful effects may occur.

There is a signiﬁcant difference between the terms “hot-pluggable” and “hot-swappable”. Hot swapping happens at the device level; that is, a hot-swappable device manages insertion/removal on its own without assistance from HP-UX commands. The disk drive(s) in the J6700 are not hot-swappable; they are merely hot-pluggable. Thus, a manual software procedure must be done in order to safely remove or insert disk drives while the system is running.

The hot-plug process allows you to replace a defective disk drive in a high-available system while it is running.

Replacing a Failed Disk Drive

In the context of replacing a failed disk drive, the system administrator must determine which disk has failed. Depending on how the system was set up, the identity of the failed drive may or may not be obvious. This determination may be done in either of two ways:

• Tracking the error message written by the LVM (Logical Volume Manager) to the system console and/or a log ﬁle. For information on LVM commands, see the man pages for vgchange, lvreduce, vgfgrestore, lvlnboot, lvextend, lvsync, etc.

• If installed, run the diagnostic utility Support Tool Manager (xstm) to determine disk malfunction.

The removal of a defective disk drive from an active ﬁle system is supported through LVM commands if hot-pluggable disks have been conﬁgured into the HP-UX ﬁle system with LVM. To provide high availability, without impact to users, the disks must also be conﬁgured as mirrored disks. Disk-mirroring is accomplished through use of the MirrorDisk/UX software (HP part number B2491BA); for information on classes, see http://www.hgp.com/education/courses/h628s.html.

No graphical user interface is currently offered through the System Administrator Manager (SAM) for doing the required LVM commands because manipulation of the LVM requires specialized knowledge that only experienced system administrators are expected to have (see below for details).

Hot-Plug Example

The following example describes a particular system problem where the solution is to replace a hot-plug disk module.

Volume group /dev/vg00 contains the two disks, with the logical volume conﬁguration as shown:

Table 1-2. Example Conﬁguration

Volume Description Volume Description

Logical Volume 1 Logical Volume 3 Logical Volume 2 Logical Volume 4 Logical Volume 3 Logical Volume 5

hardware address 10/0/12/0.0 10/0/13/0.0 device file (/dev/dsk/) c2t6d0 c2t5d0

The system problem for this example is that the disk at hardware address 10/0/13/0.0 has a head crash, and as a result, is unusable. The steps described in the Hot-Plug Procedure section below outline a method that can be used to recover from this state.

1. All of the replaced disk’s in-use extents must belong to mirrored logical volumes which were created with the “strict” option (-s); see the documentation for MirrorDisk/UX.

2. You must have an up-to-date conﬁguration backup ﬁle. This is done automatically each time an LVM command changes LVM conﬁguration.

The default backup ﬁle’s path is:

/etc/lvmconf/<

base_vg_name

>.conf

For example,

/etc/lvmconf/vg00.conf

3. The replacement disk must be the same product ID as the replaced one.

NOTE HP often uses different manufacturers for disks having the same product

number. The hot-plug manual procedure will not update the disk driver’s internal information to that of the replaced disk.

The replacement disk will have the same capacity and block size as the defective disk because they have the same product number. The only ﬁeld that could be incorrect is the string specifying the vendor’s name. This will not affect the behavior of the LVM. If it is desired to update the manufacturer’s name, the disk’s volume group must be deactivated and reactivated. See the HP-UX System Administration Tasks manual for details.

The Hot-Plug Procedure

These are the steps required to properly hot-plug a disk drive:

Step 1

• Check if the LVM found the physical volume to be defective when the volume group was activated.

• The “vgchange -a y” command would have printed the following message on the console:

WARNING: VGCHANGE:WARNING: COULDN’T ATTACH TP THE VOLUME GROUP PHYSICAL VOLUME “/DEV/DSK/cXtXdX”

THE PATH OF THE PHYSICAL VOLUME REFERS TO A DEVICE THAT DOES NOT EXIST, OR IS NOT CONFIGURED INTO THE KERNEL.

• If the status of the “vgchange -v vg02” is unknown, you may checkif this occurred by doing a vgdisplay command:

vgdisplay<

VG name

For our example:

vgdisplay /dev/vg00

• If the disk was defective at vgchange time, the following messages will be printed one or more times:

WARNING: VGDISPLAY: WARNING: COULDN’T QUERY PHYSICAL VOLUME

“/DEV/DSK/cXtXdX” THE SPECIFIED PATH DOES NOT CORRESPOND TO PHYSICAL VOLUME ATTACHED TO THE VOLUME GROUP.

VGDISPLAY: WARNING: COULDN’T QUERY ALL OF THE PHYSICAL VOLUMES

• If you see these messages, the disk was defective at the time the volume group was activated.

Otherwise, your disk became defective after the vgchange and you must continue with step 2 of this procedure.

Step 2

• Reduce any logical volumes that have mirror copies on the faulty disk so that they no longer mirror onto that disk (note the -A n option). This will take a several minutes.

lvreduce -m 0 -A n <

LV name

> /dev/dsk/<

hard drive

(for 1-way mirroring)

For example:

lvreduce -m 0 -A n /dev/vg00/stand /dev/dsk/c2t5d0 lvreduce -m 0 -A n /dev/vg00/swap /dev/dsk/c2t5d0 lvreduce -m 0 -A n /dev/vg00/ /dev/dsk/c2t5d0

The number of logical volumes that this step needs is variable. For instance, on a mirror of a root disk you should have at least three logical volumes: /stand (is lvol1), /swap (is lvol2), and / (is lvol3). Note that if your root mirror disk dies, you need to do the following:

— Follow the procedure in the section “Initial System Loader (ISL) Environment” in

the chapter “Boot Console Handler” in this document. At the Main Menu prompt

boot from the good disk. — Type y at the Interact with ISL prompt and press — Type this command at the ISL prompt and press

Enter.

Enter: hpux -lq

The -lq option stands for loss of quorum. Once this procedure has been completed the system will boot.

Step 3

• Replace the faulty disk.

•Doanioscan on the replaced disk to insure that it is accessible and also as a double check that it is a proper replacement.

For example:

ioscan /dev/dsk/c2t5d0

Step 4

• Restore the LVM conﬁguration/headers onto the replaced disk from your backup of the LVM conﬁguration:

vgcfgrestore -n <

volume group name

> /dev/rdsk/cxtxd

where x is the logical unit number of the disk that has been replaced. For example:

vgcfgrestore -n /dev/vg00 /dev/rdsk/c2t5d0

20 Chapter1

Product Information

Front Panel Components

Step 5

• Attach the new disk to the active volume group with the vgchange command.

vgchange -a y /dev/vg00

Step 6

• If the disk is not a mirror of a root disk, then skip this step.

• Run the mkboot command. For example:

mkboot /dev/rdsk/c2t5d0

• Run lvlnboot -R to relink the replaced disk into the Boot Data Reserved Area of all the Physical volumes in the Volume group.

lvlnboot -R

Step 7

• Run the lvsync command to synchronize the physical extents of each logical volume speciﬁed by logical volume path. Synchronization occurs only on physical extents that are stale mirrors of the original logical extent.

lvsync /dev/<volume group name>/<

LV name

For example:

lvsync /dev/vg00/stand lvsync /dev/vg00/swap lvsync /dev/vg00/

At this stage, your system should be fully functioning. Use the xstm command to verify.

Your workstation has a built-in Twisted Pair (TP) connector for the 802.3 (ETHERNET) or 10 BaseT/100 BaseT network. Your workstation will automatically select the correct network setting.

USB Connectors

The two Universal Serial Bus (USB) connectors support only the HP keyboard, mouse, or hub (D6804A). You can connect the HP keyboard, mouse, or hub in either of the USB connectors.

The USB mouse and keyboard were shipped with your system unit. The HP hub can be ordered separately. Note that you should consult the documentation that accompanies each input device for speciﬁc information concerning its use.

Formore information on the Universal Serial Bus, use your browser to access the following URL: http://www.usb.org.

HP Hub for USB Devices

The HP USB hub provides you with the ability to connect more than two USB devices to the workstation, as well as the ability to extend the USB device’s cable length. As an example, you may desire to locate the workstation’s keyboard and mouse at a greater distance from the workstation, but the keyboard and mouse cables are not long enough. To increase the cable length, you must make use of the USB hub’s extra cable length and connect the hub’s cable to one of the two connectors on the back of the workstation. You then connect the keyboard and mouse into their separate connectors on the USB hub.

Product Information

Internal Components

Microprocessors

The J6700 has two PA-8700 microprocessors with operating frequencies of 750MHz. Each processor has 0.75 MB instruction cache and a 1.5 MB data cache. Each microprocessor is cooled by a “turbocooler” which consists of a cylindrical heat sink and an integrated fan.

Power Supply

The power system is comprised of one apparent power factor 500W output power supply. The maximum power needed by a fully-conﬁgured SPU is 715W input power. The temperature sensor is located in the front of the power supply. The power supply weighs approximately 8 lbs. (4 kg.). Please note that the system speaker is located in the power supply.

CAUTION HP does not recommend and does not support the use of “ferro-active” or

“ferro-resonant” power correction in conjunction with the J6700 workstation. This type of line conditioner represents an older technology that is not compatible with the most recent designs in active Power Factor Correction (PFC) power supplies such as those in the HP J6700 workstations. “Ferro-active” or “ferro-resonant” line conditioners may cause an increase in total harmonic distortion and may produce signiﬁcant and unpredictable voltage regulation anomalies.

PCI Cage

The PCI (Peripheral Connect Interface) cage is located on the left side of the system board, behind the CD ROM and hard disk drive bays. There are three PCI-4X, 64 bit, 3.3v, 66 MHz slots which provide I/O expansion capabilities for the workstation. There are no primary and secondary card slots.

CD ROM and Hard Disk Drive Bays

The J6700 supports two Low-Voltage Differential (LVD) SCSI hard disk drives (one standard and one optional) and one optional ATAPI slim-line CD ROM drive. The internal SCSI Bus is independent of the external SCSI Bus.

The hard disk drives are hot-pluggable. More information on this was provided earlier in this chapter in the Hard Disk Drive section.

Voltage Regulator Modules (VRMs)

NOTE These VRMs are designed to function ONLY with the J6700 power supply.

The output is 2VDC. The maximum current is 52A.

Memory

There is a label on the inside cover of the workstation which shows the J6700’s memory loading sequence.

J6700 Memory Conﬁguration

The J6700 workstation has sixteen memory slots, labeled 0A, 0B to 7A, 7B. Memory DIMMs must be installed in pairs in this workstation, and both DIMMs in each pair must be of equal size. The DIMMs for this workstation currently come in 512 MB and 1 GB sizes. This workstation comes with two 512 MB DIMMs as its standard conﬁguration from the factory. Thus, currently the minimum memory conﬁguration for this workstation is 1GB, and the maximum is 16 GB.

DIMMs should be loaded in the order shown with 0A, 0B being the ﬁrst pair of DIMMs loaded, and 7A, 7B being the last pair loaded. Figure 2-1 shows the installation sequence.

NOTE If memory is installed improperly or it is bad and fastboot is not enabled, your

workstation’s operating system will not boot-up and a DIMM error will appear in your workstation’s LCD. For more information see the section “Displaying and Setting Fastboot Mode” in Chapter 5.

3 Troubleshooting

This chapter provides information about isolating a failing component, known as a Field Replaceable Unit (FRU), in HP VISUALIZE J6700 workstations.

Troubleshooting

Chapter Overview

This chapter contains the following main sections:

• Introduction to Troubleshooting

• Flowcharts for Troubleshooting

• Dealing with a Boot Failure

• Identifying LCD-Indicated Conditions

• Running System Veriﬁcation Tests

• Running ODE-Based Diagnostics

• LED Diagnostics

Introduction to Troubleshooting

To troubleshoot HP VISUALIZE J6700 workstations, 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, ISL diagnostics, and the Support Tools Manager online tests, which are described in this chapter.

First note any error or status messages, and then run the power-up boot ROM diagnostics, known as Selftest. If the Selftest diagnostics fail, replace the FRU that is indicated. If the tests pass but you still suspect a problem, run the ISL diagnostics and the Support Tools Manager online tests.

For a complete description of using ISL diagnostics and using the Support Tools Manager, see the Support Media User’s Manual (Part Number B3782-90176).

Flowcharts for Troubleshooting

The following four ﬁgures contain troubleshooting ﬂowcharts you can follow to isolate a failing Field Replaceable Unit (FRU). Figure 3-1 on the next page contains the main troubleshooting ﬂowchart. Figures 3-2 through 3-4 on the following pages contain the ﬂowcharts for console, bootable device, and HP-UX troubleshooting, respectively.

Dealing with a Boot Failure

This section contains information for searching for bootable media, stable storage, boot command notations, supported boot paths and the Intermediate System Loader (ISL) environment. Some of the examples in this section require the use of the Boot Console Handler, which is discussed in Chapter 5 of this handbook.

Special Considerations

When dealing with boot failures, you will need to consider the scenarios in this section.

• To boot from a known device containing a bootable operating system, type the following at the prompt:

Main Menu: Enter command > boot

where

device

is the hardware path to the device, speciﬁed in Mnemonic Style

device

[Enter]

Notation. Example: to boot an operating system stored on an IDE CD ROM, go to the Main Menu

of the Boot Console Handler and then type the following command at the prompt:

Main Menu: Enter command > boot ide [Enter]

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:

Main Menu: Enter command > boot

device

[Enter]

You are prompted: Interact with ISL (Y or N) > y [Enter] 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) on the root disk has become corrupted, boot the workstation from the backup kernel (/stand/vmunix.prev)by typing the following at the ISL> prompt:

ISL> hpux /stand/vmunix.prev [Enter]

• To ﬁnd the location of the bootable operating systems on the various media in the ﬁle system, use the search ipl command. See the next subsection, “Searching for

Bootable Media.”

Chapter 3 41

Troubleshooting

Dealing with a Boot Failure

Searching for Bootable Media

To list all devices that contain bootable media, go to the Main Menu of the Boot Console Handler, and then type the following at the prompt:

Main Menu: Enter command > search ipl [Enter]

The search command searches all buses. The search may turn up more devices than there are lines on the display. If you are using a text terminal, you can control the progress of the search from the terminal’s keyboard by doing any of the following:

• To temporarily suspend the search, press [Ctrl]-[S].

• To continue the search, press [Ctrl]-[Q].

• To halt the search, press any other key. These ﬂow-control commands do not work with a bitmapped display, but such a display can

show more than forty lines of text, so you are unlikely to need them. To search for devices of just one type that actually contain bootable media, go to the Main

Menu of the Boot Console Handler, and then type the following at the prompt:

Main Menu: Enter command > search ipl

where

device_type

is one of the following:

device_type

[Enter]

• fwscsi is the internal, Ultra2 Wide LVD (Low Voltage Differential) SCSI bus.

• scsi is the external SE/LVD SCSI bus.

• lan is all connections to the built-in LAN.

• ide is the built-in CD ROM drive.

• pci

is an optional SCSI interface in slot numbern.

Stable Storage

Stable Storage is non-volatile memory associated with the 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.

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 parameter selects the alternate boot path in stable storage.

42 Chapter3

Troubleshooting

Dealing with a Boot Failure

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 any SCSI port on the system. Workstations can only boot from the built-in LAN port. The workstation can be booted from the CD ROM drive for software installation.

Intermediate System Loader (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 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.

Chapter 3 43

Troubleshooting

Identifying LCD-Indicated Conditions

This workstation uses a 2-line LCD, with up to 16-characters per line, to display ﬁrmware/operating system progress codes. These codes are referred to as chassis codes. The information displayed on the LCD has the following format:

XXX YYYY: ZZZZZZ (Line 1) AAAAAAAAAAAAAAAA (Line 2)

Where:

XXX Three-character Operating Status YYYY Four-digit hex code identifying the code module being executed ZZZZZZ Six-digit FRU descriptor AAAAAAAAAAAAAAAA Diagnostic message of up to 16 characters

The 3-character operating status can be one of the following:

FLT (fault) TST (test) INI (initialize) SHU (shutdown) WRN (warning) RUN (running)

A hardware error has been detected Hardware being tested Hardware being initialized System being shutdown A non-optimal operating condition exists The operating system is running

Selftest Failures

Chassis codes are the key to debugging selftest errors. If a failure is found during selftest, chassis codes are displayed in the system LCD. To debug a failure:

1. In Table 3-1 starting on the next page, ﬁnd the chassis code listed on the LCD.

2. In the Boot Console Handler, use the Service Menu’s pim, pdt, and ChassisCodes commands to get additional information about the failure.

The FRU column in Table 3-1 shows messages printed on the LCD that refer to system FRUs. All codes are listed in numeric order.

44 Chapter3

Troubleshooting

Identifying LCD-Indicated Conditions

Memory Failures

The J6700 workstations require special Memory Page Deallocation to be implemented. This feature allows the workstation to provide information to the operating system about memory failures.

HP-UX uses this information to map out failing memory areas and continue normal operation. You can check the Memory Page Deallocation Table (PDT) using the pdt command in the Service menu of the Boot Console Handler (refer to Chapter 5). If a failing DIMM is replaced, use the command pdt clear in the Service Menu to clear out the PDT.

Running System Veriﬁcation Tests

HP-UX uses an online diagnostics product called the Support Tools Manager that allows system operation veriﬁcation.

Three interfaces are available with the Support Tools Manager: a command line interface (accessed through the cstm command), a menu-driven interface (accessed through the mstm command), and the graphical user interface (accessed through the xstm command).

For more information on these user interfaces, see the online man pages by entering the following at a command line prompt:

man cstm [Enter]

man mstm [Enter]

man xstm [Enter]

For information on the enhanced online diagnostics, see the Support Media User’s Manual (HP Part Number B3782-90176).

To access the Support Tools Manager, perform the following steps:

1. In a terminal window, type the following at the # prompt to invoke the command line interface:

# cstm [Enter]

2. The following message appears:

Support Tool Manager Version A.01.00 Type ‘help’ for a list of available commands. CSTM>

3. To verify the system operation, type the following at the CSTM> prompt:

CSTM> verify all [Enter]

Messages similar to the following appear:

Verification has started on device (CPU). Verification has started on device (FPU).

CSTM> Verification of (FPU) has completed. CSTM> Verification of (CPU) has completed.

4. Press [Enter] to return to the CSTM> prompt after all test results are reported.

5. To exit the Support Tools Manager, enter the following:

CSTM> exit [Enter]

If any tests failed, run Selftest and ISL diagnostics to isolate the problem.

Chapter 3 69

Troubleshooting

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 a CD ROM.

2. Type ode [Enter] 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:

• astrodiag – tests and veriﬁes the basic functionality of the Astro memory controller/I/O chip.

• siodiag – tests and veriﬁes the basic functionality of the SuperI/O multifunction I/O chip, including serial, parallel, USB, and so forth.

• wdiag – tests and veriﬁes the functionality of the PA-RISC chip.

• 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 type of memory and its slot location.

• fupdate – updates the system’s Processor Dependent Code (PDC) ﬁrmware in the EEPROM.

• 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.

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.

Using the System Board LEDs for Troubleshooting

This section provides a description of the system board’s Light Emitting Diodes (LEDs) and how to use them for troubleshooting. These LEDs are located inside of the workstation on the system board’s left-back edge. See Figure 3-5.. Note that you will have to view these LEDs through the airﬂow holes on the back of your workstation.

NOTE The SUPPLY LED is not currently implemented. Therefore, it does not

provide any troubleshooting information.

Figure 3-5. System Board LEDs

For those system problems that this section is not able to solve, you will have to call your local HP Support Representative. Before you call, record the state (on, off or blinking) of your LEDs and give this information to your local HP support representative. The representative will use this information to determine the course of action to take.

Interpreting the LED Information

Table 3-2. explains how to interpret the information the system board LEDs provide. Note that the SUPPLY LED is reserved for future functionality.

There are six LED blink sequences supported by the System Controller. The LED blink sequences are shown in Table 3-3. Note that each blink of the LED represents a tenth of a second (0.1 sec.).

If the FANS LED is ever stuck either ON or OFF, a system problem has occurred. This system problem is most likely an I2C bus hang. A potential ﬁx may be to check that the power supply cables are correctly plugged in. If this does not work, call you local HP Support Representative.

FRU Removal and Replacement

The procedures in this section describe how to remove and replace J6700 workstation FRUs. Observe the electrostatic discharge (ESD) precautions and the prerequisites for removing and replacing FRUs in the next two subsections, as well as any NOTEs, CAUTIONs, and WARNINGs in each FRU removal and replacement procedure.

NOTE If you need to install a new FRU, simply follow the procedures for replacing

the FRU in this chapter. (That is, replacement procedures are the same as those for installing new FRUs.)

Electrostatic Discharge (ESD) Precautions

To prevent damage to the J6700 workstation, observe all of the following ESD precautions while performing FRU removal and replacement procedures:

1. Remove all ESD-generating materials from the work area in which you will remove and replace a workstation’s FRU(s).

2. Stand on an ESD (static-free) mat.

3. Wear a grounding wrist strap to ensure that any accumulated electrostatic charge discharges from your body to ground.

4. Connect all equipment together, including the ESD mat, grounding wrist strap, workstation, and peripherals.

5. Keep uninstalled printed circuit boards in their protective antistatic bags.

6. Once you have removed printed circuit boards from their protective antistatic bags, handle the printed circuit boards by their edges only.

Field Replaceable Units (FRUs)

FRU Removal and Replacement

Prerequisite Steps for All Removal and Replacement Procedures

You must complete the following steps before performing any of the FRU removal and replacement procedures in this chapter:

1. Power off the workstation (either by executing shutdown -h as root, or by simply pressing the power switch on the front panel of the workstation, which accomplishes the same thing), as well as the monitor and any attached peripheral devices.

2. Unplug the workstation power cord and all peripheral devices from AC power outlets.

3. Attach the static-grounding wrist strap by following the instructions on the package. Attach the sticky end of the wrist strap to bare metal on the rear panel of the workstation.

NOTE To make access to the internal FRUs easier, you may want to place the

workstation on a table or workbench instead of leaving it on the ﬂoor.

CAUTION This workstation is designated for two-person lifting; it weighs approximately

36 to 49 pounds (12 to 22 kg), depending on the conﬁguration. Do not attempt to lift it by yourself, or injury may result.

3. The replacement disk must be the same product ID as the replaced one.

The Hot-Plug Procedure

These are the steps required to properly hot-plug a disk drive:

Step 1

• Check if the LVM found the physical volume to be defective when the volume group was activated.

• The “vgchange -a y” command would have printed the following message on the console:

• If you see these messages, the disk was defective at the time the volume group was activated.

Step 2

Step 3

• Replace the faulty disk.

•Doanioscan on the replaced disk to insure that it is accessible and also as a double check that it is a proper replacement.

Step 4

Step 5

Step 6

• If the disk is not a mirror of a root disk, then skip this step.

• Run lvlnboot -R to relink the replaced disk into the Boot Data Reserved Area of all the Physical volumes in the Volume group.

Step 7

• Run the lvsync command to synchronize the physical extents of each logical volume speciﬁed by logical volume path. Synchronization occurs only on physical extents that are stale mirrors of the original logical extent.
