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).

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
x
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

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.

You can attach a variety of pointing devices (such as a mouse or trackball) or peripheral
devices (such as printers, plotters, modems, and scanners) to the RS-232C Serial
Input/Output (SIO) ports on this workstation. Consult the documentation that
accompanies the device for specific information concerning its use.
LAN 10/100 BaseT RJ45 Connector
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.

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.

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.
