into the 7133 unit. To connect main electrical power, press the Power switch.
To remove this power, press the switch again.

Chapter 1. Using the Subsystems 5

Attention: Pressing these switches when the Power light is on can cause a
system fault unless you first make the disk drives within the 7133 unit
unavailable to the operating system. To do this:

1. Use the system-management task menus of the operating system to make
the disk drives unavailable to the system.

2. If the 7133 unit is connected to more than one adapter, make the disk
drives unavailable to the system or systems for each of the paths to the
system.

Power light

The Power light, which is green, comes on permanently when the
power-supply units within the 7133 subsystem are supplying power to the rest
of the subsystem. When the subsystem is in standby mode, this light will be
flashing. In standby mode, the power-supply units do not supply power to the
drives. This mode is set by the power/standby switch on the Model D40 or
remotely on either model if the remote power option is installed.

Check light

The Check light, which is amber, comes on if a failure occurs within the 7133
unit. The unit might be able to continue operating satisfactorily even when the
failure of a single part has been detected. The light can be set flashing by an
SSA service aid to identify the failing 7133.

ID display

The ID display is a four-character display that can be set by the three ID push
buttons.

This display normally shows the ID of the 7133 unit. If a failure occurs within
the 7133 unit, an error ID for the failure is shown, alternating with the ID of the
7133 unit; “Identifying 7133 Units” on page 14 describes these how to set the
7133 IDs, the 7133 Models D40 and T40 Serial Disk Systems: Service Guide,
GY33–0192–02, describes the error IDs.

ID push buttons

You can use these push buttons to set the ID of the 7133 unit that is shown in
the ID display. Use a ball-point pen or similar instrument to press these push
buttons.

v The left button steps through the four character positions, one position at a

time, to select the character position that you want to set.

v The center button steps through the available characters, one character at a

time, to select a character.

v The right button stores the selected ID.

If no push button is pressed within 10 seconds, the display resets to its last
valid setting.

Identifying 7133 Units

During normal operations, the four-character ID display at the front of the 7133 Model
D40 or T40 unit shows the ID of the unit. (“Subsystem Controls” on page 4 shows the
position of the ID display.) You can set these IDs by using the three ID push buttons.
The four-character alphanumeric display may show the location and ID of the 7133. For
example, on a rack-mounted Model D40, you can use two digits to show the ID of the
rack, and two digits to show the ID of the 7133, while on a Model T40, you can use all
four digits to show the ID of the 7133. You can set the ID display to represent whatever
you require. The resulting ID must, however, be unique.

Identifying Disk Drive Modules

You can use an SSA service aid to make the Check light on a particular disk drive
module flash. The status light for that disk drive, at the front of the 7133 unit, also
flashes. The appendix for your system, later in this manual, describes how to do this.

You can identify a disk drive module by the serial number that appears on a label on
the front of the module:

On the 7133 Model T40, locks on the front and back covers provide physical security
for the drives and the connections to the system unit. You do not need to remove these
covers during normal operations. The two locks use the same key. If you lock the
covers, neither of them can be opened for servicing without the use of the key. You do
not need to lock the covers for them to stay closed.

Lock

Ordering Cover-Lock Keys

For protection against unauthorized key duplication, the cover locks are high-security
locks. Keys for these locks are a factory-restricted series and duplicate keys are not
available through normal commercial channels. The serial number of the lock is
stamped on each key; make a note of this number. The additional key supplied and
your note of its number should be stored in separate secure areas.

Make a copy of the official order form on the following page, fill in the details, and send
it to the address printed on the form. As a security precaution, the manufacturer will not
honor orders that are not on the official order form.

Chapter 2. Adding Disk Drive Modules

This chapter describes how to add disk drive modules to a 7133 Model D40 or T40 that
is already installed as part of your system.

You can do this only if:

1. You are authorized by your organization to do this.

2. You have the correct disk drive module. Only disk drive modules that have a blue
trigger behind the handle on the front can be installed in 7133 Model D40 or T40
units. The storage capacity of a disk drive module is shown on the label at the front
of the module:

Capacity

Blue

Note: Disk drive modules that can be installed in 7133 Model 010, 020, 500, or 600

units cannot be installed in 7133 Model D40 or T40 units.

Attention:

v Do not remove two disk drive modules from the subsystem at the same time.
v Disk drive modules are fragile. Handle them with care. Keep them well away from

strong magnetic fields.

You do not need to remove power from the 7133 unit when adding a disk drive module.

After you have added a disk drive module to a 7133 unit, you must add it into your
system software configuration by using the system programs.

21

Before Adding a Disk Drive Module

1. Identify the slot for the new disk drive module using the configuration planning
information for your system. There should be a dummy disk drive module in the slot.

You can identify the disk drive modules that will be next to the new disk drive
module by using the Identify function in the SSA service aids. (The appendix for
your system, later in this manual, describes how to use this aid.) You cannot use
the Identify function to identify the dummy disk drive module itself because dummy
disk drive modules do not have lights or serial-number labels.

Important: Before you attempt to remove a dummy disk drive module, ensure that
the SSA loop that contains the dummy is complete. Failure to do this may result in
loss of access to other disk drives.

2. Open the front cover of the unit by gripping the cover at the sides and pivoting the
whole front cover downward.

If the slot for the new disk drive module is in a deskside unit, open the front or back
cover of the unit by:

a. If necessary, unlocking the cover using the key provided.

22 7133 Models D40 and T40 Operator Guide

b. Gripping the right-hand edge of the cover and pivoting it to the left.

The illustrations in the following instructions show a rack-mounted unit. The steps for
adding a disk drive module to a deskside unit are the same, but the parts are turned
through 90 degrees.

Chapter 2. Adding Disk Drive Modules 23

To Add a Disk Drive Module

1. Push downward on the blue trigger and pull outward the handle of the dummy disk
drive module. This action moves the module partly out of the slot.

2. Pull the dummy module out of the 7133 unit.

24 7133 Models D40 and T40 Operator Guide

Attention: The fans may increase in speed. Do not leave the slot empty for more
than 30 minutes; if you do, the 7133 unit and the disk drive modules within it might
overheat and be damaged.

Chapter 2. Adding Disk Drive Modules 25

3. With one hand supporting the new module, engage it in the groove and push it into
the slot from which you have just removed the dummy module.

The module stops before it is completely into the slot.

4. Close the handle of the module until it shuts with a click. This action pulls the
module completely into the slot.

26 7133 Models D40 and T40 Operator Guide

5. Push on the front of the module to ensure that the module is fully home.
Attention: The fans may decrease in speed.

Chapter 2. Adding Disk Drive Modules 27

6. Ensure that the Check light comes on immediately and that it goes out after
approximately 2 seconds. (If this does not happen, after checking that the new
module is properly installed, check the SSA error log for information about the
fault.)

Chapter 4. Dealing with Problems

This chapter describes what to do if you have a problem with a 7133 Model D40 or
T40, how to change a faulty disk drive module, fan assembly, or power-supply
assembly, and what information to provide when you report a problem with a 7133
Model D40 or T40 or a device installed in it.

Starting to Deal with Problems

How to start dealing with SSA problems depends on the system to which your 7133 unit
is attached. “Appendix A. Operating with RISC Systems” on page 71 describes what to
do if you are using RISC based systems. “Appendix B. Operating with PC Servers” on
page 85 describes what to do if you are using PC Servers.

Additional problem indications

If the 7133 check light is on, look at the four character display. This may be displaying
an Error ID alternating with the 7133 ID. The Error ID may be one of the following:

SLOT The 7133 controller has detected one or more unpopulated drive positions. All

positions must be populated with either a disk drive or a dummy disk drive
module. If any slot is unpopulated, correct the situation. If all positions are
populated, report the problem to your service organization.

FAN1, FAN2, or FAN3

The 7133 controller has detected a defective fan. Replace the defective fan
(see “Changing Fan Assemblies” on page 49 for how to do this) or report the
problem to your service organization.

PSU1 or PSU2

The 7133 controller has detected a defective power supply unit. Replace the
defective power supply unit (see “Changing Power-Supply Assemblies” on
page 56 for how to do this) or report the problem to your service organization.

COLD, COOL, WARM, HOT

The 7133 controller has detected an ambient temperature problem. Take
actions to correct this condition. If you consider that the detection report is
wrong, report the problem to your service organization.

Any other error ID or no error ID

Report the problem to your service organization.

35

Changing Disk Drive Modules

In some circumstances, you can change a faulty disk drive module without the
assistance of a service representative. You can do this only if:

v You are authorized by your organization to do this.
v You have the correct disk drive module. Only disk drive modules that have a blue

trigger behind the handle on the front can be installed in 7133 units. The storage
capacity of a disk drive module is shown on the label at the front of the module:

Capacity

Blue

Note: Disk drive modules that can be installed in 7133 Model 010, 020, 500, or 600

units cannot be installed in 7133 Model D40 or T40 units.

Attention:

v Do not remove two disk drive modules from the subsystem at the same time.
v Disk drive modules are fragile. Handle them with care. Keep them well away from

strong magnetic fields.

You do not need to remove power from the 7133 unit when changing a disk drive
module.

After you have changed a disk drive module in an SSA Disk Subsystem, you must
restore it into your system using the system programs.

36 7133 Models D40 and T40 Operator Guide

Before Changing a Disk Drive Module

1. Check the error log; the appendix in this book for your operating system describes
how to do this.

2. The error log contains records; each record includes a Service Request Number
(SRN).

If the SRN is in the following list, it means that a disk drive module has a fault that
can be corrected by exchanging the disk drive module for a new one:

Any SRN whose first character is ‘1’
80203
D0100
D0300

If the SRN is not in the list, do not change the disk drive module; call your
service representative and report the problem.

If the SRN is in the list, continue at the next step.

3. Find the failing disk drive module by using:
a. The location code supplied in the error log. You can find details of the location

code format in the appendix of this book that applies to your operating system.

b. The Identify function in the SSA service aids (the appendix in this book for your

operating system describes how to do this).
This service-aid function also describes the storage capacity of the failing disk

drive module. Always replace a disk drive module with one of the same capacity.

4. Important. Put the failing disk drive module into service mode. (the appendix in this
book for your operating system describes how to do this).

5. Check the lights on this disk drive module. (“Disk Drive Module Lights” on page 7
describes where these are and how to see them.)

If the check light is not on, you cannot change the disk drive module; call
your service representative and report the problem.

If the check light is on, change the disk drive module using the procedure in the
following section.

Chapter 4. Dealing with Problems 37

Identifying 7133 Models D40 and T40 Units and Disk Drive Modules

You can identify a 7133 Model D40 or T40 unit and the disk drive modules installed in it
either by the location code contained in system messages that refer to that unit, or by
using the SSA service aids.

Location Code Format for 7133 systems

See “Location Codes” in the operator guide for your system for general information
about location codes.

Pdisks, Hdisks, and Disk Drive Module Identification

The physical disk drives (pdisks) in an SSA subsystem can be configured as logical
units (LUNs). A LUN is also known as an hdisk, and can consist of one or more
physical disk drives. An hdisk in an SSA subsystem might, therefore, consist of one
pdisk or several pdisks.

The configuration software also allocates an identification (hdisk and pdisk number) to
each disk drive module during the configuration of the SSA loop. The disk drive
modules do not have fixed physical addresses.

The numeric identifiers of pdisks, hdisks, and the disk drive module slots of a 7133 are
not related to each other. For example, pdisk1 is not necessarily installed in slot 1 of
the 7133.

The system software recognizes the disk drive module by a machine-readable number
that is written on the electronics card of the disk drive module. This number is shown
also on the label at the front of a disk drive module. The service aids show the number
as the last eight digits of the IEEE 16-digit SSA unique identifier (UID).

Service actions are always related to physical disk drives. For this reason, errors that
occur on SSA disk drives are always logged against the physical disk drive (pdisk).

example, an RS/6000), that disk drive is configured only as a pdisk during the
configuration of the using system.

Identifying a subsystem or Disk Drive Module and Using Service Mode

Subsystems are identified by the disk drive modules contained in them.

To identify a disk drive module:

1. Start the system diagnostic programs.

2. From the Function Selection menu, select Service Aids.

3. This displays the Service Aids menu.
From this menu, select SSA Service Aids.

4. This displays the SSA Service Aids menu; select Set Service Mode.

Subsystem Check light at the front of the 7133 unit) flashes.

Check that the serial number on the disk drive module matches the one that you
selected.

You can select and identify more than one disk drive at a time.

7. If you are going to change the disk drive module:
a. If the disk drive is a member of an array, and you are not using the disk as an

rhdisk, remove the disk from the array using the array configuration utility. (The
SSA Adapters: User’s Guide describes how to do this.)

b. Select Set/Reset Service Mode in this menu. (For some severe errors, this

might cause an error message to appear; ignore this message.) The Check light
on the disk drive module (and the Subsystem Check light at the front of the
7133 unit) should now be on and remain on. The disk drive is in service mode.

You can now change the disk drive module, using the steps described in “To
Change a Disk Drive Module” on page 38.

If the Check light is not on, you cannot change the disk drive module; call your
service representative and report the problem.

Only one disk drive can be in service mode at a time.

76 7133 Models D40 and T40 Operator Guide

When you have finished using the service aid, select Set/Reset Identify or Set/Reset
Service Mode again. This turns off the Check light on the disk drive module and, if the

disk drive was in service mode, releases the disk drive for use by the system programs.

Problem Determination

If you have a problem with a 7133, see the operator guide for your system for a
description of what to do.

For some problems, your system diagnostics tell you to check the lights on the system
to discover which part, if any, has a fault. “Controls and Lights” on page 3 of this book
shows the position of the lights. The diagnostic programs tell you what to report to your
service representative. (“Reporting Problems” on page 69 describes other information
you should report.)

Checking the SSA Error Log

In RISC systems, when you start the diagnostic programs they automatically check the
SSA error log and present messages about any new problems that have been recorded
there. Your using system manuals describe how to start the diagnostic programs.

Service Aids

This section shows the screens for the service aids that are available when the 7133 is
attached to a RISC system.

Command Line Tools

ssaencl Command

Purpose

To allow the monitoring and changing of the status for SSA SES disk enclosures
(subsystems).

Syntax

To display enclosure component settings:

ssencl -l name [-s] [-v] [-i] [-b [card]*] [-t [threshold]*]

[-a] [-f [fan]*] [-d [drive_bay]*] [-p [PSU]*]
[-o] [-c]

To modify enclosure component settings:

ssencl -l name [[-I ID] [-U]] [-B [mode | card=mode*] [-S [d [drive_bay]*] | [b [card]*] | [p [PSU]*]|r|c|

For help, type: ssaencl -? or ssaencl -h

Description

The ssaencl command can be used to observe the existing settings of an SSA SES
disk enclosure (subsystem), or to modify the settings of that enclosure. The command
can be used only to observe or modify settings; it cannot be used to observe and
modify settings at the same time.

When the command displays enclosure settings, it displays them in tables that the user
can read easily. If the -s flag is specified, however, the command displays the settings
in colon-separated format, as used by commands such as the SMIT commands.

Flags

-l name

Specifies the name of an SSA SES enclosure or pdisk. If a pdisk name is
used, that pdisk must be in an SSA SES enclosure.

-s Displays output in colon-separated format.

-v Displays also VPD information.

-i Displays the enclosure identifier (as shown in the operator panel, if present).

-b [card]

Displays the status of the bypass cards. If no parameters are given, the status
for all the bypass cards is displayed. Valid values for the [card] parameter are:
1, 4, 5, 8, 9, 12, 13, 16.

-t [threshold]

Displays all the temperature thresholds, or only the specified temperature
thresholds. The valid values for the [threshold] parameter are:

lowarn The low-temperature warning threshold.

82 7133 Models D40 and T40 Operator Guide

locrit The low-temperature critical threshold.
hiwarn The high-temperature warning threshold.
hicrit The high-temperature critical threshold.

-a Displays the ambient temperature of the enclosure and temperature threshold
statuses.

-f [fan] Displays the status of all the fans, or of only the specified fans. Valid values for
the [fan] parameter are: 1, 2, 3, and so on.

-d [drive_bay]

Displays the status of all the disk drive bays (slots), or of only the specified
disk drive bays. Valid values for the [drive_bay] parameter are: 1, 2, 3, and so
on.

-p [PSU]

Displays the status of all the power supply assemblies, or of only the specified
power supply assemblies. Valid values for the [PSU] parameter are 1, 2.

-o Displays the status of the operator panel.

-c Displays the status of the controller card.

-I ID[-U]
