1.1

Dividing a System into Partitions

Firmware on the AlphaServer GS80/160/320 systems allows the system
to be divided into separate partitions, each running an instance of an
operating system.

Getting Started with Partitions

Multiple copies, or instances, of the Tru64 UNIX and/or OpenVMS operating
systems can be run on AlphaServer GS80/160/320 systems. With partitions, one
of these systems can be segmented into several smaller systems. Figure 1–1
illustrates the concept of partitioning; one AlphaServer GS320 system,
including processors, memory, and I/O, is divided into three separate partitions.
For example, suppose that an installation has requirements to run applications
under the OpenVMS operating system, and also needs to run applications under
the Tru64 UNIX operating system. Partitioning is one way of dividing
hardware resources such that separate operating systems, each with their own
applications, can run in each partition.
For another example, suppose that you wish to upgrade your Tru64 UNIX V4.0G
operating system to V5.1, but wish to keep running the old applications at the
same time as testing the revisions for the upgrade. Separate partitions can be
defined so that one partition runs V4.0G and another partition runs V5.1.
Further, partitions can be reallocated as required. Figure 1–2 shows how
partitions might be reallocated over a period of time on a system.

Using Partitions

Partitions can be used to consolidate the work done by separate, small
servers into one larger server.

Getting Started with Partitions

One reason for using partitions is to consolidate resources, as shown in Figure
1–3.
The left side of the figure shows three separate servers, each performing user
tasks in a separate environment. The right side of the figure shows that these
same functions can be performed on one larger server, using partitions.
In a partitioned system, most hardware failures affect only the partition in
which they occur. Thus, partitions maintain system reliability by isolating such
hardware failures.
Also, businesses may wish to support applications on a known, tested system at
the same time as debugging a new system. Partitions provide the means to
separate the activities in different partitions.
These and other applications of partitioning are described for Tru64 UNIX
systems in the Compaq white paper Managing Workload with System Partitions
and Resource Management (http://tru64unix.compaq.com/unix/literature.htm)
OpenVMS Galaxy partitioning opportunities are discussed in the white paper
on Reducing Business Risk with the New Compaq AlphaServer GS Series
Systems Running OpenVMS
(http://www.openvms.compaq.com/gsseries/index.html).

1.3

Accessing Partitions at the System Management
Console

A local user or service engineer interacts with partitions through the
system management console. The system management console is
connected directly to the system. A user may also communicate with a
partition remotely through the use of a modem.

Partition 2
Partition 1

PK-0100C-99

1-6

Getting Started with Partitions

Partitions are accessed through either a local or remote console device. A
console device may consist of a serial display monitor and a keyboard, or a
terminal emulator on a PC, UNIX, or VMS workstation attached to the system.
Figure 1–4 shows the system management console monitor with windows for
three partitions open on the monitor screen. (See the AlphaServer
GS80/160/320 System Management Console Installation and User’s Guide for
information about this console device.) In this case, a terminal emulator
displays the screens; the commands typed at each screen direct the firmware to
perform the actions requested within a particular partition.

1.4

Hard and Soft Partitions

The firmware supports two types of partitions: hard (for OpenVMS and
Tru64 UNIX systems) and soft (for OpenVMS Galaxy systems).

1.4.1

Hard Partitions (Tru64 UNIX and OpenVMS)

Hard partitions are defined using the SCM firmware by naming the
QBBs in each partition. Resources cannot be shared between hard
partitions.

1-8

Getting Started with Partitions

As shown in Figure 1–5, hard partitions are defined along QBB boundaries.
The figure shows a GS320 system containing eight QBBs divided into three
hard partitions.
There is no sharing of CPU, memory, or I/O resources between hard
partitions. The boundaries of these partitions are considered “hard.”
An instance of an operating system may run in each hard partition; these
instances run completely independently of each other.
Tru64 UNIX instances do support individual applications using a specified
percentage of a given resource, such as processor sets. This type of resource
partitioning is described in detail in the Tru64 UNIX System Management
manual.
OpenVMS implements resource sharing differently, building on SRM firmwarebased entities called soft partitions, discussed next.

Introduction

1-9

1.4.2

Soft Partitions (OpenVMS Galaxy)

Soft partitions are defined by naming the specific CPUs, memory
allocation, and I/O modules comprising each partition. CPUs can be
reassigned from one instance to another as computation load changes.
Also, soft partitions allow instances to share memory. OpenVMS
Galaxy is an implementation of soft partitions.

Getting Started with Partitions

Soft partitions allow the definition of a portion of memory as shared
memory; they also allow CPUs to be reassigned by agreement of the
operating system instances running in the partitions. The boundaries
defined by the firmware are thus considered “soft.”
Figure 1–6 shows a GS320 system with eight soft partitions set up on QBB
boundaries. Each partition has private memory. In addition, you can allocate
shared memory that all instances can use, as shown in the center of the
diagram.
In addition to shared memory, soft partitions differ from hard partitions in that,
with soft partitions, operating system instances may agree to share CPU
resources. CPUs can be reassigned to different instances as load varies.
Soft partitions are defined using the SRM firmware. The division of resources
defined can be thought of as a starting point. Once operating system instances
are running in each soft partition, resources can be reassigned as needed at the
operating system level. See the OpenVMS Alpha Galaxy and Partitioning
Guide for more information on this type of resource sharing.

Getting Started with Partitions

The figure on the facing page gives an overview of the partitioning process:

•

Planning. There are hardware, firmware, and software requirements and
restrictions to meet before you can run partitions. Chapter 2 describes the
major hardware configuration rules as of this printing. However, you
should check the QuickSpecs for the most up-to-date information on the
hardware, firmware, and software required. The QuickSpecs also list
hardware that is not supported for partitioned systems and which must be
removed from your system before partitions will run. The QuickSpecs are
available on the web at http://www.compaq.com/alphaserver/.

•

Defining Hard Partitions (if any). Defining hard partitions involves
setting certain environment variables from the SCM. Settings for these
environment variables are discussed in Chapter 3, as well as the power on
command that initializes the settings.

•

Defining Soft Partitions (if any). Defining soft partitions involves
setting environment variables and issuing an lpinit command from the
SRM. If hard partitions have been defined, you can define soft partitions
from each hard partition’s console window. Chapters 4 and 6 provide show
config and show device examples that illustrate the different SRMs for
each hard or soft partition. Chapter 5 discusses the environment variables
for setting up soft partitions and the lpinit command.

•

Booting Instances of an Operating System. Once hard and/or soft
partitions are set up, you boot an instance of the operating system from
within each partition. Chapter 7 discusses booting. Maintenance and
troubleshooting are described in Chapter 8.

Configuration Rules and Tips 2-1

2.1

Hardware Required for a Hard or Soft Partition

A partition (hard or soft) requires at least one CPU, 64 Mbytes of
memory, and an I/O riser module that is connected to a master PCI box
with a standard I/O module.

Figure 2–1 Hardware Requirements for Each Partition

1 CPU
Module

64 MB Memory

1 IOP
(I/O Riser 0)

1 PCI master box with a standard I/O module
PK-003HP-99

2-2

Getting Started with Partitions

A hard or soft partition requires at least one CPU (resident in the QBB with
I/O) and 64 Mbytes of memory. I/O requirements are that at least one local I/O
1
riser (IOR 0) be present per partition connected to a master PCI box. A master
PCI box is one with a DVD/CD-ROM drive and keyboard and mouse ports, etc.,
and contains a standard I/O module with local and modem ports for connection
to a console device.
With hard partitions, at least one QBB is required per partition. Soft partitions
allow more flexible assignment of resources; however, the two I/O riser modules
in a QBB cannot be split between partitions.
The maximum number of partitions varies according to the configuration. With
hard partitions, a two-drawer GS80 supports two hard partitions. A partition
may include more than one QBB. For example, an 8-QBB GS320 system could
have two partitions, one with five QBBs and one with three QBBs.
With partitions, a 2-QBB system supports two partitions and an 8-QBB GS320
system supports up to eight partitions. The number of soft partitions is limited
by the constraint that the two I/O riser modules in a QBB cannot be split
between partitions.
Each partition must include a master PCI box with a standard I/O module. The
standard I/O module contains both SRM firmware and SCM firmware. Hard
partitions are defined using the SCM firmware. Soft partitions are defined
using the SRM firmware.

The QBB backplane contains logic for an I/O port (IOP) with connectors for two
I/O risers. One I/O riser is shown in Figure 2–1; should two I/O risers be present
in a QBB, they cannot be split between partitions. Thus, I/O for partitions is
defined along QBB boundaries.

Getting Started with Partitions

To manage partitions, it is necessary to have access to each hard or soft
partition. With the system management console, an AlphaServer GS80/160/320
system with multiple console lines can be managed with a single device. The
system management console consists of a DECserver 90M terminal server, a
Compaq Deskpro PC, and associated hardware and software. Figure 2–2 shows
an AlphaServer GS320 system with eight partitions.
The eight-port terminal server can connect to a maximum of eight partitions.
The PC on the system management console is connected to the management
channel connector on the terminal server, and each port in the terminal server
is connected to a standard I/O module in a master PCI box that is defined as
part of a partition. The console for each partition is displayed on the PC in a
terminal emulator window.
The PC contains two network interface cards. The first connects to the terminal
server via private network. The second connects to the corporate LAN, enabling
remote operation of the system management console through Carbon Copy 32.
The PC also has an attached modem, which can provide Compaq Services
remote access to the system with Carbon Copy 32.
For information on the system management console, its use and installation,
see the AlphaServer GS80/160/320 System Management Console Installation
and User’s Guide.

Configuration Rules and Tips 2-5

2.3

Master and Slave SCMs

Multiple standard I/O modules are needed for hard or soft partitions,
introducing the need for master and secondary SCMs. The master SCM
controls the console serial bus (CSB). Other SCMs are secondary.

Getting Started with Partitions

A user needs access to an individual partition for maintenance and debugging.
This access is provided through the requirement that each partition, hard or
soft, must be attached to a master PCI box with a standard I/O module.
The standard I/O module contains both SCM and SRM firmware. Only one
SCM can control the console serial bus (CSB) at any given time. This SCM is
called the master SCM. All other SCMs are called secondary (or slave) SCMs.
A master SCM must be:

•

Attached to the operator control panel (OCP).

•

Have its scm_csb_master_eligible environment variable set to 1. (By
default, each SCM’s scm_csb_master_eligible environment variable is set
to 1. You can override a particular SCM’s eligibility by setting this
environment variable to 0 from the console connected to that SCM.)

Figure 2–3 shows a system divided into three hard partitions. One hard
partition is divided into three soft partitions. Each of these partitions has a
master PCI box with a standard I/O module containing SCM and SRM
firmware. Note that hard partition 2 is connected to three master PCI boxes.
The SRM that controls the definition of soft partitions within hard partition 2 is
the SRM residing on the standard I/O module in the master PCI box with the
lowest-numbered hose connection to that partition.
At Vaux power-up on a system with multiple SCMs, the master SCM is selected
as the one with the lowest-numbered CSB address (determined by the node ID
switch setting on the PCI box) that is also connected to the OCP and has the
scm_csb_master_eligible environment variable set to 1. The standby SCM is
selected as the one with the next-lowest CSB address that is also connected to
the OCP and has the scm_csb_master_eligible environment variable set to 1.

SCM Functionality from Master and Slave SCMs

Systemwide functionality is provided by the master SCM; hardpartition-dependent functionality is provided at the local (master or
slave) level.

Figure 2–4 shows which SCM commands affect the whole system (systemwide
functionality). As shown, commands that affect all nodes on the console serial
bus can be executed only from the master SCM. For example, commands that
display information for all CSB nodes are routed through the master SCM for
execution.
Figure 2–5 shows those SCM commands providing hard-partition-specific
functionality. The halt, reset, and power commands affect only the hard
partition in which they are executed; however, they do have –partition options
that can affect other partitions if executed from the master SCM.

PK-015HP-00

2-14

Getting Started with Partitions

There are some important things to be aware of when using partitions:

•

Halt, Fault, and Reset Buttons. Once partitions are up and running
separate instances of an operating system, pressing the Halt, Fault, or
Reset pushbuttons on the control panel causes the system to stop whatever
is going on in all partitions. The pushbutton has the same effect as using
the –all option on the SCM commands halt, fault, or reset from the master
SCM. To halt operations in an orderly manner, you must shut down
the operating system for each partition at the appropriate console
window before using these buttons.

•

Keeping Partitions within a System Box. You can maximize reliability
by defining either hard or soft partitions on system box boundaries, since
these are powered by one power subrack. In the unlikely circumstance of a
power failure of one subrack, only one partition would go down; the others
would continue operation.

•

Increasing Memory Access Efficiency in Soft Partitions. While the
configuration shown in Figure 2–7 is valid, memory access is more efficient
within one QBB. In Figure 2–7, two CPUs in QBB1 must access memory in
QBB0. If the instance in soft partition 0 occasionally needs the extra
compute power of the two extra CPUs, it is better to shift them as required
through resource sharing handled by the operating system, rather than to
define them as part of the soft partition.

•

Keeping Track of Where You Are. You will see a variety of prompts on
the console screen while you are managing partitions. The following is a list
of possible prompts and where you are when you see them.
SCM_En

Prompt given by the master SCM; n is the PCI box ID of the
master PCI box containing the standard I/O running the
master SCM. If your configuration is typical, you are most
likely in (hard or soft) partition 0.

SLV_En

Prompt given by a secondary, or slave SCM; n is the PCI box
ID of the master PCI box containing the standard I/O running
this slave SCM. If your configuration is typical, you are most
likely in (hard or soft) partition 1 – 8.

Pnn>>>

Prompt given by the SRM, where nn is the processor number.

OpenVMS operating system prompt.

Tru64 UNIX operating system prompt.

Chapter 3
Defining Hard Partitions

Both Tru64 UNIX and OpenVMS recognize hard partitions. Hard partitions are
divided along QBB boundaries, as discussed in Chapter 1. This chapter

hard partitions, as well as the power on commands used to initialize
partitions.

Getting Started with Partitions

At the SCM prompt, you set a value for the hp_count environment variable to
define the number of hard partitions on your system, and values for
hp_qbb_maskn environment variables to define the QBBs in each partition.
Figure 3–1 and Table 3–1 give an overview of the environment variables and
what they do. Environment variable settings for the hp_qbb_maskn are
discussed in the next section.

Table 3–1 SCM Environment Variables for Hard Partitions
Environment
Variable

Definition

hp_count n

The number of hard partitions you wish to create on the
system. Possible values are 0 (partitions disabled), 1 (for one
partition), 2 (for two partitions), 3 (for three partitions), and so
forth, to a maximum of 8.

hp_qbb_mask* x

For the *, you supply the number of the partition, which may
be 0, 1, 2, up to 7. (Partition numbers must be in sequence; for
example, you could not have partitions 0, 3, and 8 only.) The
value x gives a binary mask indicating which QBBs you want
included as part of the partition. See Section 3.2 for detailed
examples.

Note that if the hp_* environment variables are set, they will not change value
unless you use the set command to change them. The firmware uses the
hp_count environment variable to determine how many of the hp_qbb_maskn
environment variables to use in setting up partitions.
For example, if you change the partition settings from a three-hard-partition
setup to a two-hard-partition setup, and change hp_count from 3 to 2, the
firmware will use only hp_qbb_mask0 and hp_qbb_mask1 to define the size
of the partitions. Any settings for other hp_qbb_maskn environment variables
will remain.

Detailed Directions for hp_qbb_mask

The hp_qbb_mask environment variable is set to a value that creates a

➍

Power off the entire system.

Issue the escape sequence to return to the SCM firmware command-line
interpreter.

At the master SCM prompt (SCM_En>) check the current settings of the
hp_count and hp_qbb_maskn environment variables. The values shown
in Example 3–2 show that the system is unpartitioned.
Note that if the hp_* environment variables are set, they will not change
value unless you use the set command to change them. The firmware
uses the hp_count environment variable to determine how many of the
hp_qbb_maskn environment variables to use in setting up partitions.
For example, if you change the partition settings from a three-hardpartition setup to a two-hard-partition setup, and change hp_count from 3
to 2, the firmware will use only hp_qbb_mask0 and hp_qbb_
mask1 to define the size of the partitions. Any settings for other hp_qbb_
maskn environment variables will remain.

➎
➏

Set the desired environment variables.
Here, the power on –all command is used to initialize all partitions.

If you are defining partitions on a system that is already powered on, issue a
reset –all command to initialize the system with the new partition definitions.
For example, simply eliminate the power off –all command in Example 3–2,
set the desired environment variables as shown in Example 3–3, and issue a
reset –all command.

Example 3–3 Creating Hard Partitions from a Powered On State

Example 4–2 shows the hp_* environment variables being set from the
master SCM to define two hard partitions. The first partition consists of
QBBs 0 and 1, and the second hard partition consists of QBBs 2 and 3.

➋

Here, the show nvram reveals that the hp_count environment variable
has been set to 2, to indicate that two hard partitions are being defined.
The hexadecimal value 3 defines QBBs 0 and 1 as hard partition 0, and the
hexadecimal value C defines hard partition 1 as QBBs 2 and 3.

If you need to determine the master SCM, from which the hp_* environment
variables can be set, the show csb command displays the CSB address of the
master SCM. This address will appear in the SCM prompt.
Note that once hp_* environment variables have been set, they will not change
value unless you use the set command from the master SCM to change them.
The firmware uses the hp_count environment variable to determine how many
of the hp_qbb_maskn environment variables to use in setting up partitions.
For example, if you change the partition settings from a three-hard-partition
setup to a two-hard-partition setup, and change hp_count from 3 to 2, the
firmware will only use hp_qbb_mask0 and hp_qbb_mask1 to define the size
of the partitions. Any settings for other hp_qbb_maskn environment variables
are ignored.

➊ In hard partition 0, the hard and soft QBB numbers are still equivalent.
Both start at 0. In this case, the partition consists of hard QBBS 0 and 1.
(Assuming the hp_* environment variables were set as in Section 4.1.)

➋ Soft CPU numbers start with 0 and continue through 8, as was the case in
Section 4.4.1.

➌ The IOR numbers are as they were for the show config for the entire
system (see Section 4.4.1).

The show config listing continues with an entry for the hierarchical switch, a
memory summary, and a standard I/O summary for the partition. This section
is followed by a section giving detail for the memory boards in the partition.

➊

The hierarchical switch is considered a part of the partition.

➋

The memory summary shows the memory present in each QBB in the
partition. QBBs 0 and 1 each have 4 Gbytes of memory each. Note that
the heading “System Memory” lists total memory for this partition only.

➌

This section shows the standard I/O modules present on designated hoses
within the partition.

➍

Detailed memory listing. The total system memory (actually, for the
partition only) is 8 Gbytes. Memory is listed by board number for each
QBB in the partition. In this case, QBBs 0 and 1 each have two 2-Gbyte
boards.

➊ I/O adapters on the system are listed in order for the PCI box IDs in
ascending order. Note that the PCI box IDs remain the same whether or
not the system is partitioned. They are the settings on the node ID switches
of the PCI boxes, and are unique and constant through the system.

➋ Within PCI box, the connecting I/O riser in the QBB is listed (0 or 1).
➌ Standard I/O modules are of interest in partitions. Hard partition 1
contains two standard I/O modules.

➍ Logical hoses in hard partition 1 are listed here. Note that these numbers
remain the same whether or not the system is partitioned.

This section of the show config display lists devices connected to hard
partition 1 (see ➊).
NOTE: The device name’s adapter ID and unit number are restarted at “a” and
“0”, respectively, for second and consecutive hard partitions. This is
significant when you are defining the boot device and other parameters
for a hard partition.

➊ Looking back at the cutoff points for logical hose numbers for the two
partitions as shown by the show config displays for partition 0 and
partition 1 of this system, we can predict the division point in this example
for the dk devices (SCSI). The break is at logical hose 16. (Remember from
Table 4–1 that the logical hose number is the last number in the device
name.)

➋ Likewise, for dq (IDE CD-ROM) devices, the devices are divided beginning
with the second partition at logical hose 16.

➌ For Ethernet ports, the division occurs at logical hose 17.
➍ Both FDDI devices are in partition 0.
➎ The pk (SCSI ports) divide at logical hose 16.

Defining Soft Partitions

OpenVMS Galaxy recognizes soft partitions as well as hard partitions. Soft
partitions are the basis for dynamic resource sharing for OpenVMS, as
discussed in Chapter 1. (See the OpenVMS Alpha Galaxy and Partitioning
Guide for more information.) This chapter describes the SRM environment
variables you set to define soft partitions, as well as the lpinit command used to
initialize soft partitions.

SRM Commands That Define Soft Partitions

Soft partitions are defined by setting environment variables that define
the number of partitions, as well as the CPUs, I/O risers, and memory
sizes of each partition, the size of shared memory, and the partition to
receive error interrupts. Soft partitions are initialized with the lpinit
command.

Getting Started with Partitions

You set values for environment variables to define the number of partitions, the
CPU, memory, and I/O resources belonging to each partition, the amount of
shared memory, and the partition to receive error interrupts. Figure 5–1 and
Table 5–1 give an overview of the environment variables and what they do.

Table 5–1 SRM Environment Variables for Soft Partitions
Environment Variable

Definition

lp_count n

The number of soft partitions to create. Possible
values:
0

Default. All IOPs, CPUs, and memory are
assigned to one soft partition. No shared
memory is defined.

One soft partition is created (partition 0).

2-8

From two to eight soft partitions can be
defined.

lp_io_mask* x

For the *, supply the partition number (0 – 7). The
value x gives a binary mask indicating the soft QBB
numbers (as displayed by show config as
discussed in Chapter 4) for QBBs (containing I/O
risers) to be included in the partition. See Section
5.2 for details.

lp_cpu_mask* x

For the *, supply the partition number. The value x
gives a binary mask indicating which CPUs (using
“soft” CPU numbers, as displayed by show config
as discussed in Chapter 4) are part of the partition.
See Section 5.4 for details.

lp_mem_size* n

For the *, you supply the number of the partition.
The value n can be a size or list of sizes. See
Section 5.5 for details.

lp_shared_mem_size n

Size of memory shared by all partitions. See
Section 5.6 for details.

lp_error_target

The number of the soft partition that is to receive
error interrupts. The primary CPU of this soft
partition will receive the interrupts. If lp_count is
0, lp_error_target is ignored.

Defining Soft Partitions

5-3

5.2

Console Window for Soft Partitions

If your system has soft partitions within hard partitions, you must
select the right console window to define the lp_* environment
variables and issue the lpinit command. This is the window whose
SRM is on the standard I/O with the lowest hose number within the
partition.

5-4

Getting Started with Partitions

You must have a standard I/O module for each hard or soft partition on your
system. When you define soft partitions, you must choose the SRM console that
resides on the standard I/O module that controls the hard partition in which it
is resident. This is the standard I/O module connected to the lowest-numbered
hose in the hard partition. If cabling for the system is standard, the SRM
prompt in each case will be P00>>>.
For example, in Figure 5–2, there are two hard partitions defined on a system
with four standard I/O modules. To define soft partitions within the hard
partitions, you would choose the console window with the prompt P00>>> to
define soft partitions within hard partition 0. You would also choose the console
window with the prompt P00>>> to define soft partitions within hard partition 1.
If you cannot be sure from the SRM prompt which console window to use to
define soft partitions within a hard partition, find the one within the hard
partition from which the command show lp* works. This is the one from which
you can define the lp* environment variables.

Detailed Directions for lp_io_mask

The lp_io_mask environment variable is set to a value that creates a
binary mask in which a bit set to 1 indicates that an individual IOP
(same as soft QBB number) belongs to a soft partition.

Getting Started with Partitions

I/O ports (IOPs), defined by the soft QBB number for the QBB in which they
reside, can be assigned to logical partitions in any order. Soft QBB numbers are
displayed by a show config command. Each soft partition must contain at
least one IOP with an I/O riser connected to a master PCI box with a standard
I/O module.
Bit values for one nibble of data are as follows:
Hex

Example 5–1 Sample lp_io_mask Setup
P00>>> set lp_io_mask0 3
P00>>> set lp_io_mask1 C
P00>>> set lp_io_mask2 F0
In Example 5–1, the first command defines the IOPs in QBBS 0 and 1 as part of
soft partition 0. The second command defines the IOPs in QBBs 2 and 3 as part
of soft partition 1. The third command defines the IOPs in QBBs 4, 5, 6, and 7
as part of soft partition 2.

Detailed Directions for lp_cpu_mask

The lp_cpu_mask environment variable is set to a value that creates a
binary mask in which a bit set to 1 indicates that an individual CPU
belongs to a soft partition. The CPU numbers used in the definition are
the “soft” numbers displayed in the show config command, as described
in Chapter 4.

Getting Started with Partitions

Figure 5–4 shows some examples of bit masks for the lp_cpu_mask
environment variable on a fully populated GS320 system (up to 32 processors)
with no hard partitions. Both hexadecimal and decimal are given for bit place
values.
Note that if you are defining a soft partition within a hard partition, the SCM
firmware, when the hard partition is powered on, supplies new “soft” CPU
numbers from 0 with the QBB with the lowest hard QBB number within the
partition and proceeding upward. An SRM show config display for the
partition will show the soft CPU numbers, as described in Chapter 4. You can
use the table on page 5-7 to construct values for as many hexadecimal digits as
you need to form a bit mask.
Example 5–2 shows the SRM commands used to create lp_cpu_mask
environment variables for the configuration shown in Figure 5–4.

Example 5–2 Sample lp_cpu_mask Setup

System Memory 64 GB

➋

As shown in Example 5–3, the SRM command show config (see ➊ ) displays
the system memory size (see ➋ ). From this number, you assign the amount of
memory in each soft partition. The total amount of memory for all partitions
and that allocated for shared memory (see next section) cannot exceed this total.
Note that if less than the total amount of memory is allocated for partitions and
shared memory, the unallocated memory is unusable by any partition.
The format of the command is:
set lp_mem_size* [size | list-of-sizes]
where:
*

Partition number (0 – 7).

size

Can be specified in hexadecimal bytes, decimal megabytes (MB) or
decimal gigabytes (GB). The size must be on a 64 MB boundary. The
size must also be at least as much memory required by the operating
system that will be booted in soft partition n. For example, OpenVMS
requires 64 MB.
Can be bound to a QBB by using the form

5-10

Getting Started with Partitions

n = size
where n is the QBB number and size is as described previously.
Only one unbound (not attached to a QBB) size may be given for any
partition. Note that if lp_shared_mem_size allocates memory that
is bound to specific QBBs, so must the lp_mem_size allocations be
bound to specific QBBs.
list-of
-sizes

A comma-separated list of sizes from particular QBBs (see ➌ in
Example 5–3) for soft partition n. One element in the list of sizes must
be at least the minimum amount of memory required by the operating
system that will be booted in soft partition n. Each size can be
specified in hexadecimal bytes, decimal megabytes (MB), or decimal
gigabytes (GB). Each size must be on a 64 MB boundary.
No more than one size can be bound to an individual QBB. No more
than one unbound size can be given. Note that if lp_shared_mem_
size allocates memory from specific QBBs, so must the lp_mem_
sizen allocations be bound to specific QBBs.

Example 5–4 Examples of lp_mem_size
P00>>> set lp_mem_size0 100000000

➌

Soft partition 0 is assigned 100000000 hex bytes from any QBBs in the
system (or hard partition). (If neither MB or GB is specified, the number
is taken as hex.)
Soft partition 1 is assigned 1024 (decimal) Mbytes from any QBBs in the
system (or hard partition).
Soft partition 2 is assigned 64 Mbytes from QBB0 and 2 Gbytes from
QBB2 in the system (or hard partition).

Soft partitions within hard partitions are discussed in the next section. For
convenience, simply assume for now that the show config command in
Example 5–8 was issued from the console device for the second hard partition of
a 3-hard-partition system.
Note the QBB numbering. A “soft QBB number” is given on the left, and the
hard QBB number is given on the right (see ➊).
Note the processor numbering: two columns are given. The first column gives
the processor numbers shown on the QBB (see ➋). The second column gives
what we might call the “soft CPU numbers,” running from 0 through 7, so that
there is a unique CPU number for each CPU in the hard partition (see ➌).
Example 5–9 shows how two soft partitions might be set up within this hard
partition. Note that soft CPU numbers 0, 1, 2, and 3 are allocated to soft
partition 0, and soft CPU numbers 4, 5, 6, and 7 are allocated to soft partition 1
(see ➊). Likewise, soft QBB numbers are used in setting the lp_io_mask
environment variables.
Shared memory is divided between the two QBBs.
The lpinit command initializes the soft partitions defined, and the soft
partitions are started up with displays at their respective console devices.

➊

Here, the system is divided into two soft partitions. CPUs 0 – 7 are
defined as part of partition 0; CPUs 8 – 15 are defined as part of partition
1. The I/O in QBBs 0 and 1 are defined as part of partition 0; and the I/O
in QBBs 2 and 3 are defined as part of partition 1. To test a system with
a limited amount of memory, partition 0 is set up with 2 GB memory,
partition 1, with 1 GB, and shared memory allocated is 2 GB. The
remaining 11 GB is unallocated in this partitioning setup.

➋

The show lp* command displays the recently defined environment
variables.

➌

The lpinit command initializes the partitions defined by the environment
variables. In this case, the firmware informs the user that the system is
already (soft) partitioned, and asks if the system is to be repartitioned as
defined. The user answers yes, so the new partitioning is initialized. If
the user had answered no, the old partitions would have remained in
effect, although the environment variables would remain with the new
settings.

Getting Started with Partitions

The information in this section is for the entire system, since no hard partitions
have been defined. If hard partitions had been defined, this information would
apply to the entire hard partition from which the show config command had
been issued. The information in this section is chiefly useful for establishing:

➊

The soft QBB numbers used in defining the I/O that is included in a given
partition.

➋

The soft CPU numbers used in defining the CPU resources that are
included in a given partition.

➊

I/O adapters for the soft partition are listed for the PCI box IDs in ascending
order. Note that the PCI box IDs remain the same whether or not the system
is partitioned. They are the settings on the node ID switches of the PCI
boxes, and are unique and constant through the system.

➋
➌

Within the PCI box, the connecting I/O riser in the QBB is listed (0 or 1).

➍

Logical hoses in soft partition 0 are listed here. Note that these numbers
remain the same whether or not the system is partitioned.

Standard I/O modules are of interest in partition. All standard I/O modules
in the system or hard partition are listed. Soft partition 0 contains only two
standard I/O modules, however. By looking at the logical hose numbers (➍)
you determine which standard I/Os belong to which soft partition.

The information given on the facing page shows memory for the entire system.
If the system had been divided into hard partitions, this section would list the
memory for the hard partition of which this soft partition is a part.
Note that the hose summary is also for the entire system (hard partition).

Getting Started with Partitions

➊

IO adapters for soft partition 1 are listed here for the PCI box IDs in
ascending order. Note that the PCI box IDs remain the same whether or not
the system is partitioned. They are the settings on the node ID switches of
the PCI boxes, and are unique and constant throughout the system.

➋
➌

Within the PCI box, the connecting I/O riser in the QBB is listed (0 or 1).

➍

Logical hoses in soft partition 1 are listed here. Note that these numbers
remain the same whether or not the system is partitioned.

Standard I/O modules are of interest in partitions. All standard I/O modules
in the system or hard partition are listed. Soft partition 1 contains only two
standard I/O modules, however. By looking at the logical hose numbers (➍),
you determine which standard I/Os belong to which soft partition.

Getting Started with Partitions

Once you have defined and initialized hard and/or soft partitions on each
system, you must set SRM environment variables as required for each partition.
First, display the desired partition window at the system management console.
Directions on displaying partition windows in a system are given in the
AlphaServer GS80/160/320 System Management Console Installation and
User’s Guide.
Next, set the SRM environment variable unique to each partition. Some
examples follow.

Example 7–1 Examples of Partition-Specific Environment Variables
P00>>> set auto_action halt
➊
P00>>> set os_type unix
➋
P00>>> set bootdef_dev dka0 ➌
.
.
.

➊ In general, it is reasonable to set auto_action to halt in each partition
when you are first starting up. Once you are sure that the partitions have
been defined as you wish, you can install and boot the operating system in
each partition. Once you have partitions running smoothly, you can make
changes to auto_action as desired. Options are halt (system halts on reset
and returns to the SRM console prompt), boot (system boots on reset), or
restart (system attempts to restart operating system from where it was).

➋ Be sure to define the operating system to be run in the partition.
➌ Using the show device listings discussed in Chapters 4 and 6, define your
default boot device and other boot parameters for each partition.

8.1

How to Stop a Hung Partition

You can stop a hung operating system instance in a hard partition by
issuing an SCM halt in –partition command from the master SCM. To
stop an instance within a soft partition, issue an SRM halt command
using the CPU number for the primary CPU for the instance.

Example 8–1 Halting a Hung OS Instance in a Hard Partition
SCM_E0> halt in –par 2

Example 8–2 Halting a Hung OS Instance in a Soft Partition
$ [Ctrl/P]
P00>>>

8-2

Getting Started with Partitions

To halt an operating system instance in a hard partition, you connect to the
master SCM for the system and issue a halt in –par command for the desired
partition (see Example 8–1). This leaves the partition at the SRM console; you
would connect to the partition for further debugging.
To halt an operating system instance in a soft partition, you connect to the hard
partition in which the soft partition resides. Do a show config, if necessary, to
determine the soft CPU number for the boot processor for the desired soft
partition, and issue a Ctrl/P to halt the operating system (see Example 8–2).

Tips and Troubleshooting

8-3

8.2

Halting All Partitions to Reconfigure

You may wish to change the allocations set for partitions on your
system. Shut down the operating system in each partition. For hard
partitions, change the SCM hp_* environment variables in each
partition and reset the system. For soft partitions, change the SRM
lp_* environment variables and issue an lpinit command.

Getting Started with Partitions

In Example 8–3, a 3-partition system is reconfigured to a 2-partition system.

➊ Shut down the operating system in each hard partition currently defined.
➋ At the console window showing the master SCM, escape to the SCM.
➌ A show nvram from an SCM in any of the hard partitions reveals the
current hp_* environment variable settings.

➍ In this case, the system is set up with partition 0 consisting of QBBs 0, 1,
and 2, partition 1 consisting of QBBs 3, 4, 5, and 6, and partition 2
consisting of QBB 7.

➎ In this example, two partitions are defined, with partition 0 consisting of
QBBs 0, 1, 2, and 3, and partition 1 consisting of QBBS 4, 5, 6, and 7.

➏ The reset –all command resets the entire system.

Getting Started with Partitions

➍

In Example 8–4, the system is reconfigured from three partitions to two
partitions.

➊ Shut down the operating system in all soft partitions. At the window from
which the lpinit was issued, start with a show lp* to display the current
settings for soft partition environment variables. (If the show lp*
command does not show these environment variables, you are at the wrong
window. If you do not remember the window from which the lpinit was
issued, move from window to window until show lp* works.)

➋ Set the lp_count environment variable to 0.
➌ Issue an init command to disable partitions with the lp_count variable set
to 0.

➍ The init command queries to determine if you want to reset all partitions.
Type Y for yes.

➎ Key in the new settings for the lp_* environment variables.
➏ Issue an lpinit command.

Tips and Troubleshooting

8-7

8.3

Correcting Errors in Environment Variables

To correct a mistake in setting bit masks for partitioning environment
variables, issue an init, change the definition, and issue an lpinit.
(When you initialize partitions, any doubly allocated modules will be
noted at the master SCM console window.)

Example 8–5 Correcting a Bad Bit Mask
P00>>> init
➊
Are you sure you want to reset ALL partitions? (Y/<N>) Y
.
.
.
➋
P00>>> set lp_cpu_mask1 ffff0000
P00>>> lpinit

8-8

Getting Started with Partitions

Continuing from the previous section, where not all processors were allocated,
we do an init to reset all partitions (➊). At ➋, we correct the bit mask for
partition 0 to include the CPUs in QBB4 and issue an lpinit to initialize the
partitions.

Tips and Troubleshooting

8-9

8.4

Using Tools to Debug a Partition

You can analyze crash dumps and run WEBES from a partition while
other partitions are operating normally.

Figure 8–1 Debugging One Partition
Partition 0

CRASH!
Partition 1

Partition 2

PK-018HP-00

8-10

Getting Started with Partitions

A partition can crash, while other partitions remain up and running. You can
use the same tools to debug the problem partition as you would for a nonpartitioned system. You must first ensure that the tool has been installed on
each partition. For information on how to install the Compaq Web-Based
Enterprise Service (WEBES), go to http://www.compaq.com and search for
WEBES.
Note that in the case of faults, if a partition consists of more than one QBB, a
fault will cause faults to occur on other partitions with more than one QBB. If a
partition consists of one QBB, a fault causes no other fault in other partitions.

Tips and Troubleshooting

8-11

8.5

Powering Off or Resetting a Hard Partition

If a faulty component is found in a hard partition, you can power off
this partition for removal and replacement while leaving other hard
partitions running.

Figure 8–2 Powering Off One Partition
Partition 0

Partition 1
(Powered off)

Partition 2

PK-020HP-00

8-12

Getting Started with Partitions

If you identify a faulty component within a hard partition, you can issue a
power off command (no qualifiers) from the SRM console prompt for the
partition to remove power from the QBBs in the hard partition.
WARNING: The power off command from the SRM within a hard
partition does not remove power from PCI boxes connected
to the partition.
Similarly, you can issue a reset command from the SRM within a hard
partition to reinitialize all registers for the partition.
