IBM Active PCI Manager: Installation and User’s Guide, Version 1.0
Chapter 1. Introduction
IBM® Active™ PCI Manager is an extension of IBM Director that helps
administrators manage Peripheral Component Interconnect (PCI) and Peripheral
Component Interconnect-Extended (PCI-X) adapters in managed systems.
Specifically, Active PCI Manager offers the following tools:
v Graphical user interface
v Analyze function
v
v
v
v
Add Card wizard
Lock functions
Blink function
Refresh function
Active PCI Manager consists of three components: Server, Console, and Agent.
During installation, you designate which of these components you want to install
in a system. For more information, see the discussion of components in “Installing
IBM Active PCI Manager” on page 6.
The Active PCI Manager interface
The Active PCI Manager Console window displays information about how the PCI
and PCI-X adapters are connected in the system chassis and any input/output
(I/O) expansion drawers of a managed system. A Windows Management
Instrumentation (WMI) provider gathers the needed information from the Basic
I/O System (BIOS) codeon supported target systems. When new PCI data is
available, the IBM Active PCI Alert Driver (Alert Driver) notifies the WMI
provider, which in turn gathers the new information and notifies the Active PCI
Manager Console.
The interface presents the system information through icons in the Slot view and
Tree view and through a text table in the Table view. For details, see “The Active
PCI Manager interface” on page 12.
Analyze function
The Analyze function looks at several aspects of the system PCI bus and slot
layout. Using the layout, along with the abilities of the adapters already installed
in the system, the Analyze function runs a PCI optimization algorithm to
determine the performance of the layout.
If the Analyze function determines that the adapters are not arranged to maximize
system PCI performance, it displays the performance issues it found and, if
possible, displays a solution in the Optimization Steps window. The goal of the
Analyze function is to have each adapter in the system running in its best mode of
operation and at its highest bus speed. For details, see “PCI performance analysis”
on page 16.

Add Card wizard
The Add Card wizard works with the Analyze function to determine the most
suitable slot in which to insert a new adapter. You can select from a list of
supported adapters or define the specifications of the new adapter yourself. For
details, see “Adding adapters” on page 20.
Lock functions
You can use the Lock functions to lock specific adapter slots. The Analyze function
cannot relocate an adapter from or to a locked slot. After you right-click a slot in
the Slot view or Tree view page of the Active PCI Manager Console, you can
access the Lock functions from the menu.
For details about using the Lock functions, see the Active PCI Manager help. To do
so, click Help → Contents in the Active PCI Manager Console window. Then, click
the Lock functions topic under the Wizards and functions heading.
Blink function
You can use the Blink function to flash the physical Attention light-emitting diode
(LED) associated with any slot in a system chassis or in an I/O expansion drawer
that supports the Attention LED feature. After you click a slot in the Slot view or
Tree view page of the Active PCI Manager Console, you can access the Blink
function on the Tools menu. Alternatively, you can right-click a slot to access the
Blink function.
For details about using the Blink function, see the Active PCI Manager help. To do
so, click Help → Contents in the Active PCI Manager Console window. Then, click
the Blink function topic under the Wizards and functions heading.
Refresh function
You can use the Refresh function to manually request an update of the system
information shown in the Active PCI Manager Console window. By default, the
system information shown in the Active PCI Manager window is refreshed
automatically whenever an event such as a hot add or hot eject occurs or when a
slot flashes or turns off. With the Refresh function, you can force a refresh request
rather than waiting for a system-generated event to occur.
Run the Refresh function by clicking Tools → Refresh in the Active PCI Manager
Console. You can access the Refresh function from any of the views (Slot, Tree, or
Table) of the Active PCI Manager Console.

Manager. When you install the Server component, the Setup
program automatically installs the Console component as well.
The Server component provides the Analyze function of
Active PCI Manager.
Console
Select this choice to install the interface for Active PCI
Manager.
The Console component makes requests about the Windows
2000 Common Information Model (CIM) database. When the
Console component receives information about the target
system, it then graphically illustrates the information that was
received.
Agent
Select this choice to install the Active PCI Manager agent on
the target system.
The Agent component is a CIM provider that supplies
information about the target system to the Windows 2000 CIM
database.
10. If you are installing the Agent component, you can designate an alternative
destination folder for the installation. To do so, click Browse and select a
different directory.
If you select a destination folder that is on a different drive than that
displayed on the Select Components window, you can click Disk Space to
check the disk space of that drive. Note that if you do not change the
destination folder first, the Setup program reports zero (0) disk space
available.
You cannot change the destination directory for the installation of the Server
and Console components of Active PCI Manager. The Setup program must
install these two components into the existing directory structure for IBM
Director.
11. Click Next to continue the installation.
The Active PCI Manager Setup program checks for available disk space for all
selected components.
v If there is not enough disk space, the Setup program displays a message to
that effect, and the installation returns to the Select Components window. To
continue with the installation, you must select fewer components or a
different location for the Agent component installation and click Next again.

Uninstalling Active PCI Manager
You should uninstall Active PCI Manager before you uninstall IBM Director.
Complete the following steps to uninstall Active PCI Manager:
1. If you are uninstalling the Console component of Active PCI Manager, first
close the IBM Director Management Console.
2. Click Start → Settings → Control Panel, and then double-click Add/Remove
Programs.
3. Click IBM Active PCI Manager in the list of installed programs.
4. Click Change/Remove. The Active PCI Manager Setup program runs, and the
Welcome window opens.
5. Click Remove to remove all Active PCI Manager components, and then click
Next.
To remove only some Active PCI Manager components, do not click Remove.
Instead, see “Modifying or repairing Active PCI Manager” on page 9 for details.
6. In the Confirm Uninstall window, click OK to uninstall all components of
Active PCI Manager, or click Cancel to quit.
The Setup program detects the installed components and removes them from
the system. Additionally, it removes the CIM classes that were created by IBM
Active PCI Manager and removes the registry entries that were created during
installation. The uninstall program is automatic and prompts you when the
process is complete.
7. When the process is complete, click Finish.
In rare cases, an Active PCI Manager file remains locked, and the Setup
program is unable to remove the file. When this occurs, the Setup program
reports this fact and states that it will be necessary to restart the system after
the uninstallation. The Setup program will prompt you whether to restart the
server now or restart it later. If you click Restart Now, the system shuts down
8
IBM Active PCI Manager: Installation and User’s Guide, Version 1.0
and restarts immediately. If you click Restart Later, the Setup program closes,
and you must manually restart the system to complete the uninstallation.
Modifying or repairing Active PCI Manager
If you run the Active PCI Manager Setup program after you have already installed
Active PCI Manager, in the Welcome window, you can modify or repair the current
installation.

Chapter 3. Using Active PCI Manager Console
Although Active PCI Manager is an extension of IBM Director, it provides its own
Java™-based graphical user interface. This chapter describes how to start the Active
PCI Manager Console, describes its various parts, and explains the tasks you can
perform.
Starting Active PCI Manager Console
Complete the following steps to start the Active PCI Manager Console:
1. Start the IBM Director Console by clicking Start → Programs → Director →
Management Console. After the console starts, the IBM Director login window
opens.
2. Type the name of your IBM Director server, your user ID, and your password.
The Director Management Console can communicate with only one Director
server at a time. However, you can open multiple Director Management
Consoles at the same time, each communicating with the same or a different
Director server.
After the Director Server validates your login information, the Director
Management Console is opened and displayed in a window similar to the
following.
3. Click Systems with Windows 2000 in the Groups pane of the Director Console.
The Director Console window updates the Group Contents pane with the
names of the systems in the selected group.
4. In the Tasks pane of the Director Console window, drag and drop the Active
PCI Manager icon onto a managed-system icon in the Group Contents pane.
Alternatively, in the Group Contents pane, drag and drop the managed system
onto the Active PCI Manager icon in the Tasks pane.

11
The Active PCI Manager Console opens for the selected managed system.
The Active PCI Manager interface
The Active PCI Manager Console window has tabs to display target system
information in each of the three views: Slot view, Tree view, and Table view. Each
view provides detailed information about the adapters and slots in the system
chassis or in any I/O expansion drawers. Active PCI Manager uses the IBM
product name to identify the system chassis and I/O expansion drawer. Similarly,
it displays adapter names and slot labels for each slot.
Note: The Active PCI Manager Console window does not display information
about on-board adapters and the Service Processor slot. Active PCI Manager
does not use these adapters or slots to optimize the system.
The Slot view and Tree view pages use a combination of icons and text to display
information about the target system. The Table view displays information solely in
a text table. For a list of the icons used in the Slot view and Tree view, see the
Active PCI Manager help text. Click Help → Contents in the Active PCI Manager
Console window. Then, click Icons topic under the Graphical User Interface
heading.
As events occur that change the PCI layout on the target system, the WMI
provider supplies the information to the Windows 2000 CIM database on that
target system. The Active PCI Manager Console reads the CIM database and
updates accordingly. These events include hot-adding an adapter, hot-ejecting an
adapter, and changes in Hardware Attention LED error status.
Slot view
The Slot view page of Active PCI Manager shows a graphical representation of the
slots found in the supported system chassis and any optional I/O expansion
12
IBM Active PCI Manager: Installation and User’s Guide, Version 1.0
drawers. The top portion of the page shows the slots graphically in a left-to-right
order that corresponds to the numbers on the back of the system chassis. An icon
represents each slot, and Active PCI Manager displays different slot icons
depending on the state of the slot (locked, unlocked, empty, full, Attention LED on,
and so forth). Below each slot icon, Active PCI Manager displays the slot label for
that slot.
Note: Active PCI Manager displays the slots in lowest-to-highest order, from left to
right. However, the actual system chassis could have the lowest slot value
on the right. In this case, the display in Active PCI Manager is opposite
from the actual system chassis.
Click a slot icon and Active PCI Manager populates the Slot Attribute pane in the
lower-right portion of the window with information about that slot. If the slot has
an adapter, the Slot Attribute pane also displays information about the adapter in
that slot.
The lower-left portion of the Slot view shows the selected target system that you
plan to view and analyze. Click a system chassis icon or an I/O expansion drawer
icon to graphically show the current slot configuration in the top portion of the
Slot view. Additionally, Active PCI Manager updates the Slot Attribute pane to
show detailed information about the system chassis or I/O expansion drawer that
you have selected.
The following illustration shows a typical Slot view page.
In this example, the IBM RXE-100 Remote Expansion Enclosure is selected in the
lower-left panel. The RXE-100 has 12 slots, and the example shows all 12 slots
graphically and shows that three of those slots have adapters installed.
Additionally, the Slot view shows that one empty slot (B1) has a blue circle with an
Chapter 3. Using Active PCI Manager Console
13
″i″ in it along with an Attention (non-flashing) icon. This icon indicates that the
slot has an LED error status. See “LED error status” on page 16 for a list of the
possible LED error status messages.
Tree view
The Tree view page of Active PCI Manager shows a graphical tree hierarchy of the
slots found in the supported system chassis and any optional I/O expansion
drawers.
The left pane of the window shows the tree hierarchy representing the system
chassis, I/O expansion drawers, slots, and adapters in the target system. You can
expand and collapse the tree hierarchy by clicking the plus sign (+) or minus sign
(-) next to each icon. Active PCI Manager presents the slots in the tree in a
lowest-to-highest order that corresponds to the numbers on the back of the system
chassis.
The right pane of the window shows the attributes for the item (system chassis,
I/O expansion drawer, slot, or adapter) currently selected in the graphical tree
hierarchy. To view attributes for a different item, click that item in the graphical
tree hierarchy.
The following illustration shows a typical Tree view page.
Table view
The Table view page of Active PCI Manager provides a table of all slots found in
the supported system chassis and any optional I/O expansion drawers. This table
contains columns that identify the various slot and adapter attributes.
14
IBM Active PCI Manager: Installation and User’s Guide, Version 1.0
The table is ordered based on the Slot Label column. Click a different column
name to sort the table in an ascending order that is based on that column. When
you click the column name again, the table is sorted in a descending order that is
based on that column. Active PCI Manager does not retain any changes you make
to the sort order after you exit the program.
The following illustration shows a typical Table view page.
Menus
Active PCI Manager has two menus that provide access to all the Active PCI
Manager functions and wizards.
In the Slot view and Tree view, the Tools menu provides access to the Blink
function, Analyze function, Add Card wizard, and Refresh function. The Blink
function is available only when a slot has been clicked. The Table view has a
similar Tools menu, but it does not provide access to the Blink function.
The Slot view and Tree view also have a menu that you open by right-clicking a
slot icon. You can use this menu to flash or lock slots. The Table view does not
have any icons so it does not have this menu.
For details about using the Blink function, Lock functions, or the Refresh function,
see the Active PCI Manager help text. To do so, click Help → Contents in the
Active PCI Manager Console window. Then, click the appropriate topic under the
Wizards and functions heading.
For details about the Analyze function, see “PCI performance analysis” on page 16.
For details about the Add Card wizard, see “Adding adapters” on page 20.
Chapter 3. Using Active PCI Manager Console
15
LED error status
The Slot Attributes pane in the Slot view and Tree view pages display the current
LED error status for the selected slot. Additionally, the slot icons in the Slot view
and Tree view indicate whether the slot has an Attention LED error status. In the
Table view, the Attn LED Status column displays the current LED error status for
the selected slot. The status can be any of the following:
OK (no error)
Hot eject successful
Bus speed mismatch
Power fault on card in slot
Surprise removal occurred
Slot disabled at current speed
Too many adapters on bus
Bus connection error
When a slot has an LED error status, the icon for the slot shows a blue circle with
an ″i″ in it along with an Attention (non-flashing) icon. The hardware can turn on
the Attention (non-flashing) LED for several hardware reasons, but Active PCI
Manager cannot turn off an Attention (non-flashing) LED. Note that Active PCI
Manager shows the same Attention (non-flashing) icon for all reasons.
The following illustration shows an example of a slot icon that indicates an LED
error status.
When a slot has a Bus speed mismatch LED error status, the hardware turns off the
slot. This prevents Active PCI Manager from detecting enough PCI information
about the adapter to offer any solutions.
PCI performance analysis
The primary function of Active PCI Manager is to analyze the PCI performance of
a supported target system. The Analyze function provides this PCI performance
analysis. It runs a PCI optimization algorithm that compares the way the PCI and
PCI-X adapters are arranged in a system. If the Analyze function determines that
the adapters are arranged in such a way that the system has major or moderate
performance issues, it displays information about these performance issues. If
possible, it also provides a solution that describes recommended actions to
optimize or improve the location of adapters. For example, it can describe where to
move the adapters, what slots you can use, and what adapters to place into those
slots.
To run the PCI performance analysis on the target system, click Tools → Analyze
from any view (Slot, Tree, or Table) of the Active PCI Manager Console window.
Analyze function
In determining the PCI optimization of the target system, the Analyze function
examines all slots in the system chassis and any optional I/O expansion drawers.
This examination includes locked slots as well as turned-off slots. However, if a
16
IBM Active PCI Manager: Installation and User’s Guide, Version 1.0
slot is locked, the Analyze function will not create a solution that attempts to
relocate an adapter from or to the locked slot. Active PCI Manager locks all slots
that contain boot devices, such as disk adapters. This avoids solutions that change
the order of the boot devices, which can cause problems with starting the system
or with disk drive letter assignments. Additionally, Active PCI Manager locks any
slots that have an LED error status of Bus connection error.
You can manually lock individual slots, all slots on a bus, or all slots in the system
chassis or an I/O expansion drawer. For details about locking slots, click Help →
Contents in the Active PCI Manager Console window. Then, click the Lock
functions topic under the Wizards and functions heading.
Furthermore, the PCI optimization routine that is used by the Analyze function is
run on the Director Server. This routine can consume large amounts of memory
depending on the complexity of the slots and adapters. For this reason, the number
of entries that are allowed in the possible solution list is limited. When the PCI
optimization routine reaches the limit, it stops generating new entries and tries to
find one solution from the current incomplete list. This incomplete list might not
contain a solution, but the limit safeguards the memory usage on the Director
Server.
Potential performance issues
Several factors can affect the system PCI performance, such as incompatible
operating speeds between buses and adapters or exceeding the recommended
number of adapters on a bus. The Analyze function categorizes these issues as
major and moderate performance issues depending on the effect of the issue on
system PCI performance.
If the PCI optimization routine used by the Analyze function finds no major or
moderate performance issues, the configuration is considered optimum. In this
case, the Analyze function returns a message stating that no changes to the system
are needed.
However, if the PCI optimization routine cannot find a solution that places
adapters in buses running at the same speed and mode, the routine relaxes the
mode rules. When this happens, the Analyze function looks for a solution that can
improve the system PCI optimization even though it will not be optimal.
The major and moderate performance issues that the PCI optimization routine can
detect are described in the following sections.
Major performance issues
The Analyze function determines that there are major performance issues when
one or more of the following scenarios occur on the system being analyzed:
v All adapters installed on any bus segment are not capable of the same operating
speed.
v One or more buses are exceeding the number of adapters it can support at a
given bus speed.
For example, there are four slots on a bus, but the bus can only run two slots at
66 MHz. It cannot run all four slots at 66 MHz. However, if this bus were to
have 66 MHz adapters in all four slots, the bus would be forced to run at a
slower speed (in a PCI-backwards compatible mode) in order to get all four
cards to work. The Analyze function will detect this and report that the bus
cannot be optimized with the current number of cards installed.
v Any bus has adapters in unsupported slots.
Chapter 3. Using Active PCI Manager Console
17
At higher speeds, some systems have restrictions regarding which slots you can
populate. For example, a bus segment that provides two slots might require that
you populate only the first slot at speeds above 100 MHz. Not only must the
bus not be overloaded, but also the adapters present on that bus must reside in
the appropriate slots.
v Any bus is operating at a speed or mode slower than the maximum capability of
any adapter installed on that bus.
This is a major performance issue only when the current speed and mode of the
buses are included as a factor. This scenario occurs when you are attempting to
determine if the root configuration is optimum and which buses will require
resetting after the configuration has changed.
Moderate performance issues
The Analyze function determines that there are moderate performance issues when
one or more of the following scenarios occur on the system being analyzed:
v A 32-bit wide bus contains a 64-bit adapter.
v All adapters installed on any bus segment are not capable of the same operating
mode (for example, PCI-X versus conventional mode).
Optimization solution
The Optimization Steps window displays the results of the performance analysis
from the Analyze function. If the PCI optimization algorithm finds major or
moderate performance issues, the Optimization Steps window displays these issues
and, if possible, provides instructions on how best to rearrange the adapters. The
recommended solution is intended to optimize the system so that the adapters are
operating at their best performance.

IBM Active PCI Manager: Installation and User’s Guide, Version 1.0
The following illustration shows a typical Optimization Steps window.
In the steps of the recommended actions, the adapter names are underlined. When
clicked, the corresponding slot icon is updated in the Slot view to indicate the
recommended action. For example, step 1A indicates that the adapter should be
removed from slot 4. In this case, clicking the adapter name in step 1A causes the
slot icon for slot 4 to change to indicate that it needs to be removed. For samples
of the different icons used in the Slot view, see the Active PCI Manager help text.
Click Help → Contents in the Active PCI Manager Console window. Then, click the
Icons topic under the Graphical User Interface heading.
Important
In some cases, the Optimization Steps window will include a step to turn off the system
before following the optimization steps. This can happen when the solution recommends
that you move an adapter to a bus that is running at a speed at which the adapter cannot
run. If you do not turn off the system in such cases, the system can return unexpected
errors such as a Bus Speed Mismatch LED error status for the suggested slot.
Chapter 3. Using Active PCI Manager Console
19
The Optimization Steps window provides a Print option, and a Copy option so
you can paste the solution into a text processing application. Active PCI Manager
does not keep a history of solutions, so you must either print or copy the solution
if you want to retain it.
Adding adapters
Active PCI Manager has an Add Card wizard that works with the Analyze
function to determine the most suitable slot in which to insert a new adapter. To
start the Add Card wizard, click Tools → Add Card Wizard from any view (Slot,
Tree, or Table) of the Active PCI Manager Console window.
Note: Before using the Add Card wizard, you must run the Analyze function and
correct any noted performance issues. The Add Card wizard cannot
determine a solution if any major or moderate performance issues exist.
The Add Card wizard comes with specifications for certain adapters. In the first
window of the wizard, you can select from a list of supported adapters. If you are
using an adapter that is not in the list, use the second window of the wizard to
provide the specifications of the adapter. After you have selected or defined the
adapter you plan to use, the wizard runs the Analyze function. When the analysis
is complete, the Add Card wizard displays a suggested slot number to which the
adapter can be added. If no suitable slot is found, it displays a message to that
effect.
The Add Card wizard will not suggest a slot if using the slot for the new adapter
would make the system performance suboptimal. Further, the Add Card wizard
will not suggest that other adapters be moved to add the new adapter. Regardless,
you must decide whether to add the new adapter to available slots in the system.
Note: Active PCI Manager cannot validate the information gathered by the Add
Card wizard against the physical adapter unless the adapter is installed in
the system. If the wrong adapter information is entered in the wizard, the
suggested slot might not enable the adapter to properly function or the
system might not be optimized if the adapter is used in the suggested slot.
For detailed information about the Add Card wizard windows and defining the
adapter you want to install, see the Active PCI Manager help text. Click Help →
Contents in the Active PCI Manager Console window. Then, click the Add Card
wizard windows topic under the Graphical User Interface heading.

PCI-X I/O subsystem. Enterprise X-Architecture™
technology offers one of the first implementations
designed to the 1.0 specification level of this new
industry standard, including support for dozens of
PCI-X buses. PCI-X provides a new generation of
capabilities for the PCI bus, including more efficient
data transfers, more adapters per bus segment and
faster bus speeds for server systems. PCI-X enhances
the PCI standard by doubling the throughput capability
and providing new adapter-performance options while
maintaining backward compatibility with PCI adapters.
PCI-X technology allows all current 66 MHz PCI
adapters—either 32-bit or 64-bit—to operate normally
on the PCI-X bus. PCI-X adapters take advantage of the
new 100 MHz and 133 MHz bus speeds, which allow a
single 64-bit adapter to move as much as 1 GB of data
per second (0.5 GBps in each direction simultaneously).
(The next PCI-X specification [2.0] will support bus
speeds of up to 266 MHz.) Additionally, PCI-X
supports twice as many 66 MHz 64-bit adapters in a
single bus as PCI does.
PCI backward-compatibility mode. A state in which
the PCI or PCI-X adapter is running in a mode or at a
speed that is less than the full capabilities of the
adapter.
PCI bus. A collection of PCI slots that are physically
connected and which all must run at the same speed
and in the same mode.
PCI optimization. A task performed by the Analyze
function that compares all PCI and PCI-X adapters in a
system. The comparison is to see if they are forcing
23
other PCI or PCI-X adapters, or they are themselves
being forced by other PCI or PCI-X adapters, to operate
in a less-than-maximum state. The result is to identify a
solution that would eliminate or lessen the need for
adapters to run in a PCI backward-compatibility mode.
Peripheral Component Interconnect. A computer bus
architecture that defines electrical and physical
standards for electronic interconnection.

identifies one slot from another. You can physically

solution. The resulting suggestion from the PCI
optimization task performed by the Analyze function.
The provided solution could include adding an adapter
into a specific slot, swapping adapters between a pair
of slots, or moving an adapter to another slot in the
system.
