Media Devices

The SCSI interface is the main bus for the mass storage devices and is used to connect
disk drives, tapes and optical disks.

The SCSI bus internal to the unit is etched or embedded on the back plane, so it supports
device connection through direct insertion, without cables.

All the internal devices are included in a mechanical carrier that enables the devices to be
directly connected to the back plane. The carrier includes a SCSI converter board.

For the operator controls of the disk devices refer to “Using Internal Disk Drives” on page
2-47.

Base Unit

The base unit includes the basic SCSI device complex with 6 slots (SCSI bus A) and an
additional SCSI bus with 4 slots (SCSI bus B).

The media devices such as tape drives and CD-ROM drives are always located at the front
in the upper row of the base unit. This row can house three 5.25-inch half-high devices.

The lower device slots located at the front side are reserved for highly removable 3.5-inch
disk drives. See “Highly Removable Disks” on page 4-2, for more information about highly
removable disks.

Main Power Switch Module

The power system provides power and power regulation for all units of the 7013 J Series.
It enables you to power on and power off (also under operating system control) individual

units. This is particularly useful for handling power outages or to gracefully shutdown the
system in case of problems.

The power supply complex consists of:

• the Main Power Switch Module

• the Power Supply.

Each unit is equipped with one power supply capable of powering the maximum number of
devices that can be configured in a unit.

Each system unit houses one Main Power Switch Module on the rear left corner in the lower
part of the unit; this module contains the unit main breaker for the general AC power
ON/OFF control.

Attention: Before powering on the base system unit, be sure that the expansion unit main
power switch is set to on (I). If you attempt to power the base unit on when the expansion
unit is set to off (O), the power on will fail and an error code will be displayed in the operator
panel display.

Using the System Unit 2-5

Using the Reset/Scroll Button

Attention: When the mode switch is in Normal or Service position, pressing the

Reset/Scroll button causes the unit to reset and do an IPL (Initial Program Load). Pressing
the Reset/Scroll button while the operating system is running can result in damaged or lost
data.

The Reset/Scroll button is used to:

• Reset the system unit and cause a boot when the mode switch is set to Normal or

Service. Pushing the Reset button once may cause an incomplete reset and the system
may not restart. Therefore it is recommended to push the reset button twice for a
complete reset.

• Read out messages (scroll) after a flashing 888 is displayed.

• Start the dump program when a manual dump is needed.

• Sequentially read system configuration in Stand-By Mode and with the key mode switch

in Service position.

Pushing the Reset button once causes an incomplete reset and the system may not restart.
Therefore it is recommended that you push it twice for a complete reset.

When the mode switch is in the Secure position, the Reset/Scroll button is disabled.

Reset/Scroll Button

2-6 Operator Guide

Setting the Key Mode Switch

The key mode switch has three positions:

Normal Position
Secure Position

Service Position

The switch is used to establish the initial program load (IPL) path. The IPL loads the system
programs, checks the system hardware and prepares the system for user operation.

Before starting the system unit for normal day-to-day-operation, set the key mode switch to
the normal position. This permits the operating system to load after the power-on-self-tests
(POST’s) are completed.

Note: It is possible to set the Electronic Mode Switch (E-Key) through SystemGuard

firmware from the local or remote SystemGuard BUMP console. In Normal mode an
electronic key may be used to set Normal, Secure and Service modes. For remote
maintenance, see “Electronic Mode Switch” page 2-8. In Secure and Service
modes, the physical key setting prevails.

Normal IPL Enabled Disabled Disabled
Service IPL Disabled Disabled Enabled

Note: In this information, the name SystemGuard BUMP Console refers to the Local

Console connected to the S1 port on the system interface board.

Using the System Unit 2-7

The following list explains the uses of the key mode switch positions:
Attention: The Reset/Scroll button is active when the mode switch is in the Normal or

Service position, and pressing the Reset/Scroll button can cause data to be damaged or lost
if the operating system is still running.

OK The Normal Position is used for attended operation, which is the usual or

normal placement of the key mode switch when an operator is present and
in control of the operation of the system unit. The Reset/Scroll button is
active when the key mode switch is in the Normal position. The IPL
proceeds according to the Normal Mode Bootlist.

The Secure position prevents the system from booting. If the system is
already booted, this position does not lock the system console or block
system network communication. It also prevents an autoboot in case of a
system crash or checkstop condition.

When the operating system is up, turning the key to the Secure position
disables the Reset/Scroll button. With the key mode switch in this position,
a passerby cannot accidentally press the Reset/Scroll button and cause a
loss of data.

The Service position is used for attended operation when hardware or
software service is conducted. The Service position activates operating
system console sequences that support error determination (debug) and
storage printout (dump). In the Service position, the system unit attempts to
IPL from the media drive. The IPL proceeds according to the Service Mode
Bootlist.

The key mode switch is also used for the following:

• To indicate to the diagnostic programs that there is no console available. This is

done by setting the key mode switch from Service to Normal and then back to Service
when a c31 is displayed on the operator panel display.

• To start a dump. If the system is booted in Normal mode, a manual dump is started with

the key mode switch set to Service and pressing the Reset/Scroll button. If the system is
booted with the key mode switch set to the Service mode, a dump is started by setting
the key mode switch to Normal and pressing the Reset/Scroll button. If the Reset/Scroll
button is pressed twice, the system reboots.

If there is a problem with the system unit, refer to

the

Problem Solving Guide and Reference

before setting the mode switch to the Service position or pressing the Reset/Scroll button.
Attention: Do not set the key mode switch from Normal (OK) to Service while the system is

booting. Instead, wait until the boot is completed and then change the mode switch setting.

2-8 Operator Guide

Electronic Mode Switch

The electronic mode switch (E-key) enables you to remotely change the status of the key
mode switch and:

• places the system for maintenance or debug purpose from a remote location, from
Normal to Service mode, without a person physically being present near the system to
change the key mode switch position,

• assists remote access and service of a customer installed machine from a central
customer hub (CH) or IBM service center and to run off-line and online diagnostics from a
remote location to isolate a problem to the FRU level,

• activates from an enabled terminal (via a software command) the use of the maintenance
features on the remote line

• breaks a remote maintenance session by the service people, if some intrusion attempt is
suspected

• prevents non-authorized access to the system setting the system in Secure mode.

The Electronic Mode Switch has validity only when the operator panel key mode switch is
set to the Normal position. It is able to electronically move the position of the ”key mode
switch” on the operator panel in the following way:

Key Mode
Switch

Electronic
Mode Switch

Status of the System (*)

Normal Normal Normal

Secure Secure
Secure Set to any mode Secure
Service Set to any mode Service

Note: (*) The status of the system matters only during IPL and in off-line maintenance

mode; once the Operating System is up and running, the key mode status is
relavent only for maintenance application software and diagnostic aids.

The following functions of the key mode switch cannot be performed remotely by setting the
E-Key:

• Indicate to the diagnostic program that no console is available

• Start a manual dump.

See the

AIX Version 4 System Management Guide: Communications and Networks

and the

keycfg command for detailed information on the electronic mode switch.

rear side of each unit (base and expansion) to off.

2. Set the power switches of the external devices to Off.

General Information about Multiple Systems

If your system is attached to another system, certain actions performed by an operator can
affect either one or both systems, and these actions can require further consideration before
any changes are made. Some actions requiring further consideration are:

1. Starting and stopping the communication with other system

2. Running diagnostics on one of the systems

3. Analyzing the error log information

4. Installing adapters or devices on one of the systems

5. Using the wrap plugs with the diagnostics.

When the system unit is attached to another system, make sure you isolate this system unit
before stopping the operating system or running diagnostic programs. Some system cabling
changes (such as installing wrap plugs or removing a device from the configuration) can
require the operator to perform an action on the attached system before making the change.

Using the System Unit 2-13

Terminals and Printers

Several terminals and printers can be connected to the system. All information concerning
their technical characteristics and setup is contained in

AIX Version 4 System Management

Guide: Operating System and Devices.

System Consoles

In 7013 J Series systems two RS-232 lines on the system interface board can be reserved
for the maintenance environment. The connection to the system can be done directly (local
line) or via a modem and a dedicated leased line or a dial-up switched phone line (remote
line). If the maintenance is not enabled, these two lines can be addressed as normal tty
lines.

If the maintenance feature is enabled, the two system consoles are defined, depending on
which port on the system interface board the console is connected to, as follows:

BUMP Console refers to the terminal connected to the S1 port of the system

interface board and is normally used as system console. This
console can be a local terminal or a remote terminal or terminal
emulator in the customer hub center. If the related flag to control
the maintenance environment is properly set, the BUMP console
allows the use of off-line maintenance features.

Service Console is connected to the S2 port of the system interface board. When

the related flags to control the maintenance environment are
properly set, it enables the remote operator (IBM service center) to
perform maintenance and AIX commands in every system condition
(stand-by, init-time and run-time) as well as the local operator does
from the BUMP Console.

If there is a system problem, the S2 line is able to perform a dial-out function, which sends
an error message to the service center, enabling the remote operator to isolate the system
problem.

During a remote connection both the BUMP console and the service console have control of
the system, each one becoming an echo copier of the other. This condition permits the local
operator to control the remote operator for security reasons. The local operator (customer)
can interrupt the connection established by the remote operator either locally by setting the
key mode switch to Normal or Secure, or remotely through an escape sequence to change
the state of the E-key (if the key mode switch is set to Normal and the E-key is set to
Service).

If neither the S1 nor the S2 line are configured as BUMP lines, the Maintenance menu is not
available on these lines. In this case a limited maintenance menu is provided in Stand-by
phase (main power off, only BUMP is alive). This menu is protected by a keyword and is
available only to service people.

General Information for 5.0GB 8 mm Tape Drives

• Use only “Data Grade” 8 mm tape cartridges. These cartridges are identified by either a

“Data”, “D” or “D8” marking on the data cartridge.

• Remove the tape cartridge from the tape drive when it is not used, and store the cartridge

vertically in the cartridge case.

• Do not attempt to open the door on the data tape cartridge. This door covers and

protects the magnetic tape material from dirt, dust and damage.

• Avoid touching the tape because this can cause loss of data.

• Keep the drive door closed except when loading or unloading a cartridge.

• Back up and then discard any tape cartridge that repeatedly produces error messages.

The error information is in the system error log.

• Clean the tape path regularly according to the cleaning procedure of the 8 mm tape drive.

Use only recommended cleaning cartridges; other cleaning cartridges can permanently
damage your 8 mm tape drive.

• If the cartridge has been stored in an environment different from the drive, the cartridge

must be acclimated to the new environment before use. Follow the instructions included
with each new cartridge.

Attention: Do not use video grade cartridges in the 8 mm tape drive. Video grade tapes can
be unreliable and may cause permanent damage to the 8 mm tape drive.

Using the System Unit 2-17

Setting the Write-Protect Tab on 8 mm Tape Cartridges

Setting the write-protect tab on a tape cartridge is necessary so that information is not
accidentally lost. When the write-protect tab of a tape cartridge is set (window closed),
information can be read from the tape, but cannot be written to it.

The window on the tape cartridge controls write-protection as follows:

Window
Closed

Window
Opened

Tape is Write-Protected

Tape is NOT Write-Protected

Performance

The 8 mm tape drive employs sophisticated error recovery techniques to protect your
valuable data. When the drive reports an irrecoverable error, it has reached a point where
further retries may only damage the tape and other actions must be taken.

Under the best of conditions, an irrecoverable data error should occur no more frequently
than once every 4 years on a drive, assuming a 1GB back up 6 times a week. However,
tape cartridges that have been damaged, exposed to environmental conditions outside of
the recommended range, or worn out can greatly increase the frequency of irrecoverable
data errors.

Also, a drive that has not been regularly cleaned or that is worn out can contribute errors.
The environment that the drive and media operate in is a major contributor to the reliability
of the recorded data. A good environment will enhance the reliability, while an environment
that does not comply with the recommended limits may cause lost saves and damaged
media to occur.

It is possible, however, to have other influences (power surges, or a dust particle, for
example) which cause a transient error that cannot be duplicated. Such transient errors
should be very infrequent, and repeated occurrences should be further investigated to
locate the cause.

Usage

For those customers with more than one computer system, the 8 mm tape drive is designed
to support data interchange between systems. However, transporting the cartridge between
two systems not within the same environment could cause permanent damage to the
cartridge and resulting loss of data if precautions are not observed.

These precautions include:

• Careful handling

• Proper position of the cartridge (it should be kept on its edge)

• Always keeping it within its clear plastic dust cover

• The environmental limits recommended for the media should not be exceeded.

If the cartridge has been stored in an environment different from the drive, the cartridge
must be acclimated to the new environment before use. Follow the instructions included
with each new cartridge.

2-18 Operator Guide

Loading the 8 mm Tape Cartridge

Before loading the tape cartridge, make sure the power is on and the write-protect switch on

depending on the position of the tape when the unload button is pushed.

If the tape cartridge cannot unload and has to be removed manually from the drive, contact
your service representative.

2-20 Operator Guide

Types of 8 mm Tape Cartridges

Test Tape Cartridge Only use this

specially labeled

tape cartridge (found in the
media kit with the 8 mm tape drive) to check out the operation
of the drive or when running diagnostics. Do not use it to save
programs or data.

Data Tape Cartridge Use this

non-labeled

cartridge for saving your programs or
data. There is a data tape cartridge in the media kit to help
start your tape operations immediately. Later, if you order
additional cartridges, they are shipped five to a package. Each
tape cartridge provides up to 5/10GB of storage. Any
cartridges you use must be compatible for use in this tape
drive and certified for data applications.

Cleaning Tape Cartridge Be sure to observe all of the instructions that come with the

cleaning cartridge. Use this cartridge to clean the tape paths
of the 8 mm tape drive. Discard this cartridge after it has been
used 12 times. Additional cleaning cartridges can be ordered.
Refer to the “Preventive Maintenance ”section for more
details.

Preventive Maintenance

There are some simple preventive maintenance operations which should be performed
periodically, to ensure the correct functioning of the system and its devices. Particular care
should be taken in using devices such us streamer and tape devices, to ensure their
efficiency and avoid data loss problems.

This section contains the description of these maintenance operations.

Cleaning the Tape Path on the 5GB 8 mm Tape Drive

Attention: Do not use video cleaning cartridges in the 8 mm tape drive. Video cleaning

cartridges can damage the 8 mm tape drive. Some video cleaning cartridges are extremely
abrasive. An 8 mm tape drive may be permanently damaged after only a few cleaning
operations using an abrasive-type cleaning cartridge.

The 8 mm tape path should be cleaned either approximately every 30 hours of tape motion
or once a month. The 5GB 8 mm tape drive counts the number of hours of tape motion and
indicates when the tape path requires cleaning when the lighted disturbance status light
(amber) is on.

More frequent cleaning may be required if the drive is operated in a dusty environment or in
humid conditions. If dust is allowed to accumulate, the drive has to perform more reads and
writes. This can cause a loss of data and may be prevented by regularly scheduled cleaning
of the drive.

The cleaning cartridge cleans the drive up to 12 times before to be discarded. If you attempt
to use an 8 mm cleaning cartridge more than 12 times, the tape drive automatically detects
the error and ejects the cleaning cartridge with the disturbance status light (

amber)

remaining on.
Before loading the 8 mm cleaning cartridge, make sure the power to the 8 mm tape drive is

on.

Using the System Unit 2-21

Loading the 8 mm Cleaning Cartridge

1. Grasp the edges of the 8 mm cleaning cartridge with the window side of the cartridge on
your left.

2. Slide the cleaning cartridge into the opening of the front of the 8 mm tape drive until the
loading mechanism pulls the cartridge into the drive.

3. After the 8 mm cleaning cartridge has been fully inserted into the 8 mm tape drive, the
following cleaning operations are performed automatically:

– The cleaning tape is loaded into the tape path.
– The drive is cleaned by moving the cleaning tape forward for approximately two

minutes.

– The tape is unloaded and the cleaning cartridge is ejected from the tape drive when

the cleaning operation is complete.

A successful cleaning operation is indicated when the disturbance status light (

amber)

goes off.

Tape Handling

When loading a tape in the drive, the cartridge should be removed from the case very close
to the front panel of the drive to reduce accumulation of airborne dust and dirt particles. The
same process should be followed when removing the tape from the drive.

Do not permit smoking near the tape drive, as smoke particles can cause data errors.
Don’t use excessive force when inserting or removing the cartridge from the drive. If it

seems to be hung up, gently repeat the load or unload process.
If the cartridge is placed inside a briefcase, and in such a way kept from moving around, it

may be possible to safely transport it through hostile environments.
The case should be carried out directly to the storage area and not be exposed too long

periods of high or low temperatures.

2-22 Operator Guide

It must never be left in a car window, where sunshine can rapidly heat the air, and never left
in a car overnight.

It should be noted that airport-style metal detectors and hand held scanners will not affect
the data stored on the 8 mm tape.

8mm Data Cartridge should be stored vertically and in the supplied case.

• Recommended Operating Environment:

– 5°C to 40°C
– Relative Humidity 20% to 80% non condensing
– Max Wet Bulb to 26°C

• Recommended Storage Environment:

– Temperature 15°C to 25°C
– Relative Humidity 40% to 60% non condensing

Note: Before using a data cartridge, allow it to acclimate to the operating environment (24

hours or the amount of time it has been exposed to dissimilar conditions).

Archive Life

If proper storage conditions are maintained, quality 8 mm tapes can have a recorded data
archive life of over 30 years:

• Use tapes with 4 to 20 passes on them. In the first few passes, new tapes shake off or
shed excess magnetic media and binder deposited during the tape manufacturing
process. These can result in higher soft error rates during the first few passes.

• Pre-condition the tapes:

– Write/Read tape to measure error statistics (from LBOT to LEOT)
– Do this a minimum of 4 passes and a maximum of 20 passes
– Do this on a known good drive
– Physically examine tape pack winding for quality wind
– Use only tapes that have temperature stabilized.

• Maintain constant environment:

– Best environment is 18C (65F) at 40% RH
– Control environment while transporting tapes
– Ensure no chemical conditions exist
– No dust
– Have positive pressure air.

• Long Time Archiving Conditions:

– 5°C to 32°C
– 20% to 60% RH (non condensing)
– Wet bulb 26°C maximum

• Local Archiving Conditions Range:

– 18°C to 40°C
– 40% to 60% RH (non condensing)

• Store on edge in their protective enclosures and don’t stack anything on top of them.

Using the System Unit 2-23

• Keep the drive clean.

• Store data in a streaming (not Start/Stop) mode. Run the tape from BOT to EOT at

normal speed.

• Exercise the tapes once every 12 months by reading the entire tape, to remove any

stress which has built up in the tape pack during the storage interval. This interval can be
lessened at lower temperature conditions, and should be increased at higher temperature
conditions.

General Information for 4.0GB 4 mm Tape Drive

The 4.0GB 4 mm tape drive is an internal streaming tape drive that is used to:

• Save and restore system data files.

• Archive important records.

• Distribute operating system software upgrades.

The 4 mm tape drive is designed to be attached to any system using a single-ended
interface meeting the Small Computer System Interface ll (SCSI-ll) Standard ANSI
X3.131-199X Rev . 10h.

The 4 mm tape drive has the following features:

• Capacity of 4.0GB per cartridge. 8GB is typical with data compression and with DDS2
data cartridges.

The actual capacity per cartridge varies depending on the application and the type of data
cartridge being used.

• Data transfer rate is 400 KBps. 800 KBps is typical with data compression.
Note: Data compression activated is the default setting from the factory. Data

compression is usually controlled by the application software.

• Read and write of DDS|||| tape cartridges in 2.0GB per cartridge format.

• A status light that indicates when it is time to clean the tape path.

• Internal diagnostics that are activated when the 4 mm Diagnostic Cartridge is inserted

and loaded into the drive.

Recommendations

Attention: Tape cartridges that do not carry the proper DDS symbol cannot be written to

and their use will cause the 4 mm tape drive to report an error.

• Use only 4 mm Digital Data Storage (DDS) cartridges.
Attention: Use of other than recommended cleaning cartridges can damage your tape drive

and will void the drive warranty.

• Clean the tape path by using the recommended cleaning cartridge. Follow the instructions

on the cartridge.

• Back up and then discard any tape cartridge that repeatedly produces error messages.

The error information is in the system error log.

• Do

not

open the door on the data cartridge that covers the tape. This door protects the

magnetic tape material from dirt, dust, and damage.

• Do

not

Setting the Write-Protect Tab on 4 mm Tape Cartridges

The window on the tape cartridge controls write-protection. When the write-protect tab of a
tape cartridge is set (window open), information can be read from the tape, but cannot be
written to it. When the write-protect tab of a tape cartridge is not set (window closed),
information can be both written to and read from the tape. Trying to write to a 4 mm data
cartridge with the window open causes an error.

Environmental Considerations for 4 mm Data Cartridges

Information in this section describes operating and storage conditions including temperature,
relative humidity, and maximum wet bulb data.

Attention: The manufacturer has specified a set of temperature and humidity ranges in
which the 4 mm data cartridge can operate with ease. Only regular cleaning procedures, as
described in “Cleaning the Tape Path on the 4.0GB 4 mm Tape Drive” on page 2-32, are
required when operating the cartridge within this range. The risk of possible data loss is

Using the System Unit 2-27

increased if 4 mm tape cartridges are operated, stored, or shipped outside the temperature
or humidity ranges shown in the following table.

Before using a cartridge, always let it adjust (acclimate) to the operating environment. Do
this by placing the cartridge with its container in the operating environment for as long as it
has been away from this environment or for 24 hours, whichever is less.

Acclimation is necessary for any data cartridge that has been exposed to a different humidity
environment or a temperature change of 11°C or 20°F or more.

Operating in Harsh Environments

The 4 mm tape drive is ideally suited to streaming operations, as opposed to tape
movement operations involving multiple stop/starts and random searches. When the tape is
used for frequent stop and start operations, streaming movement is beneficial and should be
used whenever possible. This can be accomplished by ensuring that any save or restore
operation is the only active operation performed by a device connected to this SCSI I/O
controller.

Any tape that has been used outside the ranges specified in the previous table for an
extended period of time (50 passes in 40 hours of nonstop operation) should not be used as
an archival tape. Exposure to the environment will deteriorate the magnetic and physical
strength of the tape. Do not store important data on a tape that has been used outside the
specified ranges; transfer the data to a new tape for reliable archiving.

4 mm Data Cartridge Erasure

Most bulk eraser devices do not have the capability to erase 4 mm data cartridges. To
properly erase an 4 mm data cartridge with a bulk eraser device, the erasure rating must be
at least 2000 oersted.

The 4 mm tape drive erases residual data before writing new data on the data tape.

Tape Cartridge Data Capacity

The 4 mm tape cartridge capacity is defined as the amount of data that can be stored on the
cartridge. The following variables affect the amount of data that can be stored on a tape
cartridge:

• Size of the data file

• Number of file marks per file

• Compatibility mode (2GB or 4GB)

• Media rewrites.

2-32 Operator Guide

Cleaning the Tape Path on the 4.0GB 4 mm Tape Drive

The 4 mm tape path should be cleaned either approximately every 30 hours of tape motion
or once a month, whichever occurs first. The 4 mm tape drive monitors the recording quality
of the tape cartridge and indicates that the tape path requires cleaning when the disturbance
status light (amber) is on.

More frequent cleaning may be required if the drive is operated in a dusty environment or in
humid conditions. If the dust is allowed to accumulate, the drive has to perform more reads
and writes. This can cause data loss, and may be prevented by regularly scheduled cleaning
of the drive.

The cleaning cartridge cleans the 4 mm tape drive 50 times before it needs to be discarded.
If you attempt to use a 4 mm cleaning cartridge more than 50 times, the tape drive
automatically detects the error and ejects the cleaning cartridge with the disturbance status
light (amber) remaining on.

Before loading the cleaning cartridge, make sure the power to the 4 mm tape drive is on.
To load the 4 mm cleaning cartridge, do the following:

1. Grasp the edges of the 4 mm cleaning cartridge with the window side of the cartridge

facing up.

2. Slide the cleaning cartridge into the opening on the front of the 4 mm tape drive until the

loading mechanism pulls the cartridge into the drive.

Tape Cartridge Data Efficiency

Note: For maximum efficiency, operate the 1/4-Inch tape drive in the streaming mode

whenever possible.

The 1/4-Inch tape cartridge efficiency is defined as the amount of data that can be stored on
the cartridge and the data rate at which the data can be read from the tape cartridge. When
in use, the tape in the cartridge is moved at a constant speed of 72 Inches per second.

The following variables affect the amount of data that can be stored on a tape cartridge:

• Streaming mode or non-streaming mode

• Size of the data file

• Number of file marks per file

• Tape length

• Variable post/preamble

• Compatibility Mode (QIC120/QIC150/QIC525/QIC1000).

Using the System Unit 2-37

Setting the Write-Protect Tab on 1/4-Inch Tape Cartridges

Setting the write-protect tab on a tape cartridge is necessary so that information is not
accidentally lost. When the write-protect tab of a tape cartridge is set (pointing to SAFE),
information can be read from the tape, but cannot be written to it.

The write-protect tab positions for a typical cartridge are shown in the following illustration.
Use a small screwdriver to turn the arrow to the desired position. The arrow must be
pointing in one of the two directions shown in the illustration.

Re-tensioning

The tape drive works best when it is operated as a streaming tape. Before the first use of a
1/4-Inch cartridge you must retension the tape.

If the tape drive is on when a tape cartridge is inserted, the drive immediately retensions the
tape. Operating system commands can be used to change this default setting. Refer to the
operating system commands manual for your system for more information.

2-38 Operator Guide

Cleaning the 1/4-Inch Cartridge Drive

It is recommended to clean the read/write heads:

• after any period of 8 hours use

• after the first use of a new cartridge.

The frequency of cleaning depends on the number of hours of daily use, on average, once a
week.

For effective cleaning, it is recommended to use a 1/4-Inch tape unit cleaning cartridge.
Whenever a new tape unit is brought into service, the following operations should be

performed:

• A complete cycle of winding/rewinding, which has two results:

– it tightens the magnetic tapes
– it cleans the magnetic medium.

• The tape unit should be cleaned with the cleaning kit.

It is also necessary to carry out a winding/rewinding cycle on any tape unit which has not
been used recently.

Environmental Considerations for 1/4-Inch Tape Cartridges

Information in this section describes operating and storage conditions including
temperature, relative humidity, and maximum wet bulb data.

Attention: The manufacturer has specified a set of temperature and humidity ranges in
which the 1/4-inch data cartridge can operate with ease. Only regular cleaning procedures
are required when operating the cartridge within this range. The risk of possible data loss is
increased if 1/4-inch tape cartridges are operated, stored, or shipped outside the
temperature or humidity ranges shown in the following table.

Before using a cartridge, always let it adjust (acclimate) to the operating environment. Do
this by placing the cartridge with its container in the operating environment for as long as it
has been away from this environment or for 24 hours, whichever is less.

Acclimation is necessary for any data cartridge that has been exposed to a different
humidity environment or a temperature change of 11°C or 20°F, or more.

Chapter 3. Using SystemGuard

This chapter introduces the SystemGuard service processor which is included in all
Symmetric Multiprocessor models.

Introduction

SMP servers include a service processor, called SystemGuard, as a standard feature.
SystemGuard continually monitors the hardware as well as the operating system. If, for

instance, a CPU fails, the system detects this, reboots itself automatically and runs the
built-in diagnostics on the hardware. If the CPU is detected as bad during the initial program
load (IPL) or reIPL, the CPU is disabled. Likewise, if memory is detected as bad during IPL
or reIPL, it is disabled.

SystemGuard allows diagnostics and maintenance to be performed either locally or
remotely. The SystemGuard processor makes it possible for these remote systems to be
managed from a central location. SMP servers can even be set up to automatically call a
Service Center if they fail to boot successfully.

The main features of the SystemGuard are:

• Initialization process flow management

• Local as well as remote control of the system (turning power on or off, diagnostics,

reconfiguration, maintenance)

• Console mirroring to make remote actions visible and controllable by the customer

• Dial-out to a support center in case of system boot failure

• Run-Time surveillance

3-2 Operator Guide

SystemGuard Power

SystemGuard has its own DC power boundary. This means that even if the system power is
off (power button of the system in the off position), SystemGuard is still powered on, as long
as the unit is still plugged into a power outlet and the main power switch on the back of the
system unit is on. This allows control of the system even though the system is down. The
only way to turn off the SystemGuard power is to turn off the main power switch at the back
of the system unit or unplug the power cord.

A more detailed description of the system power states can be found in “Appendix G.
System Power States.”

SystemGuard Components

SystemGuard introduces new hardware and firmware components:

• a microprocessor called the Bring-Up MicroProcessor (BUMP)

• a Flash EEPROM

• a Backup EPROM that enables the system to boot in case of a Flash EEPROM failure.

Part of the SystemGuard firmware is stored in the BUMP EPROM; part is in the Flash
EEPROM. The Backup EPROM contains a subset of the Flash EEPROM .

SystemGuard Bring-Up MicroProcessor Overview

The SystemGuard Bring-Up MicroProcessor (BUMP) controls the system when the power is
off or the AIX operating system is stopped. System Guard performs the following:

• Controls the power-on (PON) tests, the power-on self tests (POST) and loading of the
AIX operating system.

• Responds to local or remote BUMP console commands to set the mode or set system
parameters.

• Runs the SystemGuard programs using the STANDBY MENU or the MAINTENANCE
MENU.

• Monitors the “heartbeat” from AIX, if the feature is enabled and AIX is running.

SystemGuard releases control of the system to the AIX operating system after it is loaded. If
the AIX operating system stops or is shutdown, SystemGuard again controls the system.

The BUMP console (attached to S1 port) provides the normal input. The service console
(attached to S2 port) provides remote service access to the BUMP. Access to both of these
consoles is controlled by flags.

The Operator Panel

The Operator Panel is the first level of user interface to SystemGuard.
The Operator Panel has the following features:
Power button It should generally stay pushed in all the time if you want to be able to

power on or off the system remotely.

Reset button It resets SystemGuard to the Init phase and, depending on the key position,

reboots the system to Maintenance or to AIX Multi-User.

LCD display It is made of two rows of sixteen characters. It displays the word

Stand-By

in the Stand-By phase, or it displays the usual three-digit boot up codes.

Physical Key It uses the international symbols for Normal, Secure and Service modes.

This key should generally stay in the Normal position because the modes
can be changed electronically when the physical key is in the Normal
position.

disconnecting the operator panel
removing the CEC enclosure

When NVRAM is drained it results in a reset of the TOD to 1969 which affects applications.
Draining NVRAM also causes a loss of configuration data.

3-4 Operator Guide

SystemGuard Consoles

SystemGuard works with two types of consoles:

• The

Bump Console

, which is an ASCII terminal attached to the S1 serial port. This
console provides the normal input to the BUMP. It can be local or remote. The line speed
for the BUMP console must be set to 9600 baud for either type of connection.

• The

Service Console,

which is an ASCII terminal attached to the S2 serial port. This
console is usually remote and located in a customer support center or a service support
center. This console enables the support center to work with SystemGuard and/or AIX.
The support center needs specific authorization from the customer to access
SystemGuard remotely .

Physical and Electronic Key

Normal, Secure, and Service modes can be set physically by turning the Physical Key or
electronically by executing the electronic key command. The Physical Key and the
Electronic Key together define a state called the

System Key

. The Electronic Key can only
be turned if the Physical Key is in Normal position. Refer to “How to Set the Electronic Key”
on page 3-39 for details on how to set the Electronic Key.

Following are various Electronic and Physical Key combinations and the resultant System

SystemGuard Phases

During boot up, SMP servers go through five different phases: Stand-By, Init, Maintenance,
Boot, and Run-Time.

Stand-By Phase

The Stand-By phase is present anytime the system unit power is off, and the SystemGuard
power is on.

At this phase, the AIX operating system is not yet loaded; the system unit power is not on,
and the word Stand-By is displayed on the Operator Panel display.

The SystemGuard is active, and it can receive commands from the BUMP console or
Service Console (either local or remote). You can enter the SystemGuard Stand-by menu
from this phase.

The Stand-By phase ends when the power button on the Operator Panel is pressed or the
power-on command is entered on the BUMP Console or Service Console.

Using SystemGuard

3-5

Init Phase

Init phase is entered when the power button on the Operator Panel is pressed on or when
the power-on command is entered on the BUMP Console or Service Console.

If the System Key is in Normal mode, the BUMP runs the built-in or resident power-on
(PON)-tests on the system hardware, IPLs on the first available processor, runs the
functional power on self-tests (POST) on the I/O subsystem to check the system, and finally
loads the AIX operating system.

If the System Key is in Service mode, and if several conditions are met, the system loads
the SystemGuard MAINTENANCE MENU. These conditions are: the Autoservice IPL flag
disabled, the BUMP console enabled, and a Valid Service Contract.

If the System Key is in Secure mode, the system enters the Stall state, and the LCD
displays the three-digit code 200. The initialization of the system stops until the Physical Key
is set to Normal or Service. The Stall state is exited, and control of the system is passed to
AIX.

Maintenance Phase

The maintenance phase is entered from the Init phase if the system key is in service mode.
If the BUMP console present flag is set, the MAINTENANCE MENU is displayed on the

BUMP console, and the system waits for an operator action. The maintenance menu
choices are described on page 3-21. Various maintenance tasks can be performed from this
menu. When maintenance tasks are complete, the system can be booted, powered down, or
reset.

Boot Phase

SystemGuard enters the Boot phase from either the Init phase or the Maintenance phase. In
this phase the system is initialized and control of the system is passed to the operating
system. Control of the two serial ports is switched to the operating system and the Run-Time
phase is entered. If a valid boot block is not found and the system key is set to Service,
SystemGuard returns to the Maintenance phase.

Run-Time Phase

This is the phase where the AIX operating system is in control of the system. The Run-Time
phase is entered once the AIX operating system is loaded and takes control of the consoles.

When AIX is stopped again, for example due to a shutdown, the system goes back to the
Stand-By phase.

3-6 Operator Guide

Phase Change (Stand-By to Init)

The phase change from Stand-By to Init is called crossing the power boundary. This is
achieved by pushing the power button on the Operator Panel or by typing the keyword
power at the Stand-By prompt (>). Note that if you type power while the power button is not
pushed in, nothing happens until you press the power button. In this case, the power
command has been taken into account by SystemGuard, and you don’t have to reenter it.
The power command is the default power on command sequence, which you can change
from the maintenance menu or AIX service aids.

SystemGuard, checks for a special downloadable diskette (if in Service mode), checks the
Flash EEPROM, and then produces an output. The following is an example of what appears:

BUMP FIRMWARE – February 16, 1995

#
FLOPPY NOT READY!
DO YOU WANT TO UPDATE FLASH FROM LINE S2[y/n]? n

BUMP FIRMWARE – May 19, 1995
ID xx.xx – POWER_ON in FLASH PROM

The message FLOPPY NOT READY! means that there is no downloadable diskette in the
diskette drive.

Note: This message is only displayed when IPLing in Service mode.
The special diskette could be:

• Code to be downloaded into Flash EEPROM

• Code to change the VPD in the EEPROMs of the SMP system

Power-on (PON) Tests

PON tests are run by SystemGuard whenever the system power comes on. There are two
types of tests:

• A comprehensive set of tests are performed on the processors, cache, memory and
related hardware when the Fast-IPL flag is disabled.

• A minimum core set of tests are performed on the processors, cache, memory and
related hardware during fast-IPL which cannot be turned off.

Following is an example of PON test output for the Fast-IPL type of test.

A flashing 888 is displayed if PON tests cannot start. If the PON test hangs, a three-digit
code corresponding to a failed component is displayed.

Note that the system IPLs on the first available physical processor. If for any reason
processor 0 is not available, the system IPLs on processor 1, and then on 2 so on until a
processor is available. If all the processors are disabled, the PON test fails, and
SystemGuard treats this as a hardware component failure and go into the MAINTENANCE
MENU in Service mode. In Normal mode, the PON test initiates dial-out, if possible, and go
into Stall state afterward. No IPL proceeds. Processors can be manually enabled again in
Service mode through the MAINTENANCE MENU. This can also be repaired locally by:

• Turning the system power off

• Moving the Physical Key into Service position

• Enabling at least one processor from the STAND-BY MENU

3-8 Operator Guide

There are other resident PON tests to check other system resources. These tests are a
subset of the SystemGuard maintenance offline tests, and reside within the flash EEPROM.
These tests are divided into the following groups:

BUMP Quick I/O Test Group

These tests check the accessibility and the functions of the
standard and direct I/O components from the BUMP: Async lines
(S1, S2, and S3), EEPROMs, NVRAM, Flash EEPROM, and TOD
(Time-Of-Day).

JTAG (Joint Tests Action Group) Test Group

These tests check the chip-to-chip connections using the JTAG
features.

Direct I/O Test Group These tests check the accessibility of the Standard and Direct I/O

components from the CPUs: IONIAN, NVRAM access, EPROM
access, TOD, and the diskette.

CPU Test Group These tests are performed by all of the processors and check the

status of the CPU cards: processor, address translation, L1 and L2
caches.

DCB (Data CrossBar) and Memory Test Group

These tests check the status of the system planar and memory
cards: data/address lines accessibility, memory components, ECC,
memory refresh (CPU checkstop).

Interrupt Test Group These tests collectively check the interrupt system: BUMP-CPU,

CPU-CPU (CPU checkstop).

MCA Test Group Not applicable
CPU Multiprocessor Test Group

These tests check the multiprocessor mechanisms, atomic
instructions, cache coherency, main memory sharing, and
multiresources sharing.

Phase Change (Init to Boot)

The maintenance phase is entered from the Init phase if the system key is in service mode.
If the BUMP console present flag is set, the MAINTENANCE MENU is displayed on the

BUMP console, and the system waits for an operator action. The maintenance menu
choices are described on page 3-21. Various maintenance tasks can be performed from this
menu. When maintenance tasks are complete, the system can be booted, powered down, or
reset.

Phase Change (Maint to Boot)

SystemGuard enters the Boot phase from either the Init phase or the Maintenance phase. In
this phase the system is initialized and control of the system is passed to the operating
system.

Phase Change (Init to AIX Load and Run-Time)

Similar to the entry into the Init phase, there is a distinct line when entering this phase. At
this line, SystemGuard gives up control of the system and passes it to the loaded code
(AIX). This is indicated by the three-digit code 299 on the consoles and Operator Panel.

Since SystemGuard is also giving up control of the two serial lines, nothing can be displayed
on the consoles. The usual three-digit boot indicators are still displayed on the Operator
Panel. Note that the code 570 virtual SCSI devices being configured can take
several minutes for each card in the SMP system.

When the boot indicators have reached c33, AIX has progressed enough to display its own
boot messages on the system console. However, this is no longer the SystemGuard
Console; it is the AIX console.

SystemGuard Parameters and Flags

A certain number of SystemGuard parameters and flags can be changed through different
SystemGuard menus, from the Diagnostics interface and from AIX. Basically, there are four
different groups of flags:

Service contract flags These flags enable Service Console usage, maintenance usage

and determine if dial-out messages are sent to IBM or to a
Customer Service Center. These flags are stored in the SID
(System Identification) field of the System EEPROM.

Diagnostics flags These flags are used to control the service, diagnostics and

maintenance from a customer point of view. For example, the
customer can modify one of these flags to authorize setting the
Electronic Key from the Service Console or to authorize the dial-out.

Modem and Site Configuration flags

These flags allow the customer to customize modem configuration
for the Service Console.

Phone numbers flags These are the dial-in and dial-out phone numbers and the operator

voice number.

3-10 Operator Guide

Working with SystemGuard

SystemGuard parameters and flags may be changed from different locations. They can be
changed from the SystemGuard STAND-BY MENU, the SystemGuard MAINTENANCE
MENU, the Diagnostics interface, and also from AIX.

When the key signal is received, SystemGuard clears the screen and displays the
SystemGuard prompt. At this point, a keyword can be entered. The supported keywords are:

power This keyword starts the system, exactly as if the power button is pushed.

You can change, disable or enable this keyword: see “Power-On Command
Parameters” on page 3-33 for details. Turning the system power on makes
the system enter the init phase. Thus, if the Key Mode Switch is in the
Service position, and if the

AutoService IPL

flag is disabled, you enter the

Maintenance Menu

.
sbb This keyword displays the STAND-BY menu.
It is important to understand the following flowchart.

When the system is in Stand-By mode and the System Key (Physical or Electronic Key) is in
Service mode, the STAND-BY MENU can be accessed and SystemGuard executed.

If you turn the system unit power on from Stand-By mode with the System Key in the Normal
position, the system boots to AIX Multi-User.

If you turn the system unit power on with the System Key in the Service position, you can go
to the MAINTENANCE MENU or to Diagnostics, depending on the state of three flags:
SystemGuard Console Present, Autoservice IPL, and Service Contract Validity.

If you power on the system with the System Key in Secure, the system stalls.
Here is some information on the meaning of the different flags:

BUMP Console Present flag

When the BUMP console is enabled, the LED codes and System Guard
messages are displayed on the console during the Init phase. If the BUMP
console is not enabled, it is like a regular system; no codes and no
messages are displayed on the console during the Init phase. Only AIX
messages appear when the system starts loading AIX.

Note that if you are running the level 5 of the SystemGuard firmware, the
BUMP Console is disabled by default, and if you enable it, it is disabled after
every shutdown. If your system is in Service mode, you might go to
Diagnostics instead of Maintenance due the SystemGuard Console being
disabled by default.

If you are running level 7 or higher of the SystemGuard firmware, the BUMP
Console is enabled by default and stays enabled after a shutdown.

Autoservice IPL flag

If enabled, this flag means that you want to go to Diagnostics when booting
with the System Key in Service mode.

Service Contract flag

This flag is preset at the factory and is not variable. The Service Contract is
always valid. This flag allows the service center to access the system and
do some maintenance. The Service Contract is set by default to an
unlimited number of days (exactly 32767 days).

SystemGuard Menus

SystemGuard menus are low-level menus; they make extensive use of abbreviations or
acronyms. Refer to the glossary on page X-1 for a full list of these acronyms and
abbreviations.

SystemGuard is menu-driven, and menu choices are usually numbered. Letters are
sometimes used and can be entered in either lowercase or uppercase (SystemGuard is
case insensitive). The letter x is often used to exit the current menu and return to the
previous menu (or leave SystemGuard, if given from the main menu). Commands are only
treated after you press the Enter key. Until you press the Enter key, you can use the
Backspace key to edit a command. If you enter a command that does not match the
available options, a beep signals that an invalid selection has been made.

3-12 Operator Guide

Stand-By Menu

The STAND-BY MENU can only be entered when the system is in Stand-By mode (the word
Stand-By must be displayed on the LCD display). Perform the following steps to bring up the
ST AND-BY MENU.

1. With Stand-By displayed on the LCD display press the Enter key on the BUMP console.
The Stand-By prompt is the greater than (>) sign.

2. To enter the STAND-BY MENU from here, set the System Key into Service mode, either
by setting the Physical Key to Service or the Electronic Key to Service. To set the
Electronic Key to Service, follow the procedure on page 3-39.

3. Press the Enter key again.

4. Enter the keyword sbb to display the STAND-BY MENU.

The STAND-BY MENU appears with several options, as follows:

Select(x:exit): 0

Note: It is also possible to enter the ST AND-BY MENU from the Service Console if the

remote authorization flag is enabled. The Electronic Key can be set from the Service
Console with the same escape sequence.

The STAND-BY MENU allows the system administrator to display the physical configuration
of the system (CPUs, memory, I/O, and so on) and to set flags, such as the

Fast IPL

flag,

and the

BUMP Console Present

flag. The Fast IPL flag causes the system to skip the

second phase of the power-on tests. The

BUMP Console Present

flag allows the BUMP
console to be enabled or disabled during boot up. This menu also enables the service
representative to test the interconnection between the BUMP and different components
through the I2C bus or the SSbus. For instance, it is possible to send a specific string of
characters to the LCD and read the result on the Operator Panel display. Or, it is possible to
turn on the LEDs on the Operator Panel, or to turn on the power supplies and fans without
allowing the system to IPL.

How to Display the System Configuration

The system configuration can be displayed through the STAND-BY MENU or through the
MAINTENANCE MENU.

Displaying Configuration through the Stand-By Menu

This option displays the system configuration table. This configuration can be viewed on the
LCD of the Operator Panel if the console is not configured. This is done by pressing the
reset button with the mode switch in the Service position.

To display the configuration of the system, enter the STAND-BY MENU, and from the Main
menu, select Display Configuration (option 0). The first-level screen is displayed with
features and devices that can be configured.

The value set for all flags is permanent until a new change is performed (except for FAST
IPL, which is automatically cleared at boot). For a complete list of default values for flags

3-16 Operator Guide

and parameters (set during manufacturing), see the table in “Default Parameter Values” on
page B–1 of the service guide for your system. The following flags can be managed:

• Remote Authorization: Only the local operator can enable this flag to enable remote
maintenance to be performed. Both the local and remote operators can disable it.

• BUMP Console Present: If enabled, SystemGuard displays the MAINTENANCE MENU
on the BUMP console (line S1). If disabled, the MAINTENANCE MENU is not available
on the BUMP console.

• Autoservice IPL: When enabled, this flag enables an automatic IPL even if the Key Mode
Switch is in the Service position, thus avoiding the display of the MAINTENANCE MENU.

• Extended Tests: This parameter determines under what conditions extended power on
self-tests are run at IPL time, after the regular power on self-tests (POSTs). If the
parameter is enabled, the extended tests are run. If the parameter is disabled, the
extended tests are not run.

• Power-On Tests in Trace Mode: When enabled, supports the running of POST tests in

trace

mode, which gives extra information about how tests are conducted. A dedicated tty

line is required, this is to be used only when directed by service support personnel.

• Power-On Tests in Loop Mode: When enabled, SystemGuard loops on the POST tests
and does not IPL.

• Fast IPL: When enabled, the long POST tests are not run, shortening the INIT phase.
This feature lets you start the machine quickly, when the test performance is not
necessary. This flag is not permanent. It only remains set until the next IPL, at which point
it is automatically cleared.

• Set Electronic Mode Switch to Normal: This command sets the Electronic Mode Switch to
the Normal position. Keep in mind that the Electronic Mode Switch is only taken into
account if the Key Mode Switch is in the Normal position. The Electronic Mode Switch is
also set to Normal each time the Key Mode Switch is moved.

Set Unit Number

Use this option to assign logical numbers to units that you add to your system.
Whenever a new unit is added, this command must be run to update the unit configuration

table.
Simply enter 2 in the main STAND-BY MENU to select this option. The process of assigning

a unit number is automatic: there is no need to pick a number.
An RS-485 bus interconnects all system and expansion units, each being addressed using a

logical number of 0 or 1. The base unit, where the SystemGuard and the operator panel are
present is the master of the RS-485 bus, and is always given logical number 0. The first
expansion unit is assigned the logical number 1.
