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 10.20 or 11.0 operating system booted on your system. They represent the different system activities.

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 J6000 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 B5403BA); 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 check if 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 Enter.

—Type this command at the ISL prompt and press 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.

•Do an ioscan 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/cxtxdx

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

For example:

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

22

Chapter 1

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.

Power Cord Connector

Plug the power cord into the power cord connector to provide AC power to the workstation. The J6000 power cord is rated at 15A for a 100–120V source.

RS-232C Serial Connectors

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.

For more 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.

LVD Product Information

Internal Components

Microprocessors

The J6000 has two PA-8600 microprocessors with operating frequencies of 552 MHz. Each processor has 0.5 MB instruction cache and a 1.0 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 J6000 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 J6000 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 J6000 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 J6000 power supply. The output is 2VDC. The maximum current is 52A.
