PREFACE
This manual contains information necessary to establish
and control operation
of a CDC ® Network Operating
System
(NOS) Version 1.4 and is intended for use by the
central site (system) operator. NOS was developed by
Control Data Corporation to provide network capabilities
for time-sharing and
transaction processing, in addition to
local and remote batch processing on CDC CYBER 170
Series; CDC CYBER 70 Series Models 71, 72, 73, and 74;
computer systems; and 6000 Series Computer Systems.
AUDIENCE AND ORGANIZATION
You are assumed to be familiar with the CYBER 170,
CYBER 70, or
6000 Series computer systems and with
operating system concepts in general.
If you have limited or no previous NOS experience, you are
encouraged to read the following sections of this manual
first.
Section 1
Section 2
Section 3
Section 4
Appendix B
Appendix D
Introduc
ti on
Deadstart: This section describes
the process
by which NOS is made
operational and ready to process
user jobs.
Operation Under
DSD Control: This
section provides information
concerning console operation and
the DSD commands that form the
primary operator interface to NOS.
Cautions are included with the
description of commands
that should
be used with
extreme care or at the
direction of the si te analyst.
DSD Displays: This section contains
a description and illustration of the
DSD displays that may be brought to
the console screens to monitor
system operation.
Operator Messages: This appendix
contains a
sorted listing of the
status and error messages that are
issued by NOS.
Peripheral Equipment Operation:
This appendix contains information
concerning the manual operation of
each peripheral device associated
with NOS.
Since the job requirements of the system operator may
vary from one installation to another, this manual should be
used in conjunction with established policies and procedures
provided by the installation.
60435600 L
Although all information contained in this manual is
considered
relevant and necessary for you, a substantial
amount of the information requires that you are
experienced and thoroughly familiar with the subject and
its application with respect to system operation. For
example, before you can use the commands described in
section
5, Operation Under DIS Control, an installation may
require
that you have an overall understanding of NOS
operation. Another installation may specify which DIS
commands you can use, if any.
CONVENTIONS
Extended memory (EM) for the CYBER 170 Models 171,
172, 173, 174, 175, 720, 730, 750, and 760 is
extended core
storage (ECS). EM for the CYBER 170 Model 176 is large
central memory (LCM) or large central memory extended
(LCME). ECS and LCM/LCME are functionally equivalent,
except as follows:
• LCM/LCME cannot link mainframes and does not
have a distributive
data path (DDP) capability.
• LCM/LCME transfer errors initiate an error exit,
not a half exit. Refer to the COMPASS
Reference Manual for complete information.
Model 176 supports direct LCM/LCME transfer COMPASS
instructions (octal codes 014 and 015). Refer to the
COMPASS Reference Manual for complete information.
In this manual, the acronym ECS refers to all forms of EM
on the CYBER 170 Series. However, in the context of a
multimainframe environment or DDP
access, model 176 is
excluded.
RELATED PUBLICATIONS
The NOS Manual Abstracts is a pocket-sized manual
containing
brief descriptions of the contents and intended
audience of all
NOS and NOS product manuals. The
abstracts can be useful in determining which manuals are
of greatest interest to a particular user.
Control Data also publishes a Software Release History
Report of all software manuals and revision packets it has
issued. This history
lists the revision level of a particular
manual that corresponds to the level of software installed
at the site.

INTRODUCTION
1
NOS provides four types of job processing.
Local batch processing
The user
enters jobs at the .central site and the
system processes them using only the
central site
peripheral equipment attached to the computer.
Remote batch processing
The user submits jobs from
remotely located 200
User Terminals, 731-12/732-12/734 Remote Batch
Terminals, or CDC CYBER 18-05
Remote Batch
Terminals.
Deferred batch processing
The user submits jobs
entered from an interactive
terminal to the batch ,queue for processing; their
output can be routed to user-specified peripheral
equipment or
remote batch locations.
Interactive terminal processing
The user
enters jobs from an interactive network
terminal or a time-sharing terminal.
SYSTEM CONFIGURATION
NOS supports the following equipment. The specific
configuration may' vary,
but consists of elements of the
following equipment.
Peripheral processors (PPs)
10, 14, 17, and 20 PP configurations of CYBER
, 170 Series computers and CYBER
70 Models 71,
72, 73, and 74 computers; 7, 8, 9, 10, and 20 PP
configurations of 6000 Series computers.
Central exchange jump/monitor exchange jump
(CEJ/MEJ)
All of the CYBER 170 Series computers and
CYBER 70 Models 71, 72, 73, and 74 computers
are equipped with CEJ/MEJ. It is an option on the
6000 Series computers. This option improves job
performance and should be used if
it is available.
Display console
Basic equipment for all CYBER 170 Series
computers includes a single
screen display
console. Two single
screen-consoles are available
optionally~ CYBER 70 Models 71, 72, 73, and 74
computers and 6000 Series computers use the 6612
dual screen display console.
60435600 K
Mass storage
A minimum of 60 million characters of mass
storage on any of the following devices.
Extended core
storage (ECS)
844 Disk Storage Subsystem
885 Disk Storage Subsystem
A dedicated permanent file device is
recommended in addition
to system mass storage.
Peripheral equipment
Any of
several combinations of the following
peripheral equipment.
580 Line Printers
405 Card Reader
415 Card Punch
667, 669, 677, and 679 Magnetic Tape Units
6671 Multiplexers for communication with
200 User Terminals and 731-12/732-12/734
Remote Batch Terminals
6671 or 6676 Multiplexers for communication
with
interactive terminals
255x Network Processing Unit
Distributive data path (DDP)
The DDP option enables PPs to read and
write
onto ECS directly rather than use the CPU
coupler.
OPERATOR/SYSTEM COMMUNICATION
Both NOS and the programs running under NOS use the
display screen to bring information to your attention. You
can respond
to or instruct the operating system by entering
information via the console keyboard.
Two
NOS routines, DSD and DIS, provide the interface
between the console hardware and other system software.
They maintain a current display of system or job status and
process commands you type
at the keyboard. DSD is the
system display routine; information
pertaining to all jobs
appears
on the screen. DIS is the job display routine; the
screen shows data from a single job only. DSD has control
of the console until you initiate DIS.
1-1

At all times DSD occupies PP1, one of the 7 to 20
peripheral processor units in the system. PPO always
contains the system monitor routine
MTR which oversees
system
activities. DIS resides in a PP assigned by the
system
at the time it is called.
Under DSD, the normal operating mode, you can
communicate with the system or any
of the jobs under
system control. Once a job begins execution, however, you
can only respond to job requests for equipment assignment
or other actions, change priority or field length, or
stop
execution permanently or temporarily.
In contrast, DIS operating mode provides more control of
job execution.
You must advance each control statement
in the job. Since you can add control statement
instructions from the keyboard, the job need not execute
exactly as it entered the system. Commands to DIS include
those
that allow changes in register contents shown in the
exchange package,
as well as those that control such items
as field length or time limit.
You can use the
DIS capability for entering control
statements to perform utility tasks or dump permanent
files.
DIS is used most often by system analysts. Section 5
details procedures for using DIS.
OPERATING THE KEYBOARD
Figure 1-1 shows the keyboard on a CYBER 170 Series
console. The PRESENTATION CONTROL switch, located
to the right of the spacebar, allows selection of a left
screen display only, a right screen display only, or both left
and right screen displays of reduced size on a split screen.
When in the LEFT position, only those displays referred to
in the following sections as left screen displays appear.
Only those referred to as right screen· displays appear when
the switch is in the RIGHT position. A split screen showing
both the
left and right displays appears when the switch is
in the middle or MAINTENANCE position.
If a 6612 dual
screen display console is used, the requested displays
appear simultaneously
on the left and right screens,
respectively; there
is no PRESENTATION CONTROL
switch on the k~yboard.
Each keyboard entry to DSD is a single line usually ending
with a period.
As you enter characters from the console,
the system displays the accumulated
entry on the lower
left portion of the left display screen. When you press the
carriage return (CR) key, a command is examined for
legality. If
acceptable, the system processes the command
and clears the keyboard entry.
If the command is not
acceptable, an error message appears above the entry.
Then press
either the erase key (Ieft blank key) which
clears both the command
entered and the error message, or
the backspace
(BKSP) key which deletes only the last
charcter displayed. Use the BKSP key to delete the entry
to the position of the error and enter the correction.
You can use the keyboard to initiate and control equipment
assigned and job progress.
DSD processes keyboard entry
of commands as follows: as you type each character at the
console,
DSD checks the accumulated entry for a match
against the
table of possible commands. When DSD has
received enough
characters to recognize the command, it
automatically fills in the remaining portion of the
command.
In general, DSD fills in the rest of the command
after three to five characters have been entered. If the
character entered is not within the legal range, or not
recognized as
part of a legal command, it is rejected and
not displayed.
Example:
To
request that the error log dayfile be displayed on
the left console screen, the appropriate DSD command
is
A, ERROR LOG. Begin by typing A. DSD checks
this input but cannot recognize the command since
eight
other commands also begin with the letter A.
Then enter the comma (,). Because four other
commands also begin with these characters, DSD still
cannot recognize the command. However, when you
enter E, the command becomes unique and DSD fills in
the· remainder of the entry on the display (RROR
LOG.). If you
do not wait for DSD to complete the
command,
but continue to type in the remaining
characters yourself, those characters are ignored.

PPU BUSY. t
DSD signals that a keyboard entry is complete by
intensifying individual characters in rotation. At this time,
press the CR key.
DSD checks the command and begins
processing if
it is found to be acceptable. If the command
is processed successfully,
it is erased from the display
screen. However, if DSD must wait for a resource to
become available (such as a channeI), or if the command
was not
acceptable, one of the following messages is
displayed above the command.
DSD is waiting for a PP to be assigned so that it
can process a command.

DEADSTART 2
Deadstart is the process that makes the system oper-
ational and ready to process jobs. System deadstart
requires a certain amount of your intervention.
This manual assumes
that a deadstart file exists and is
configured to
meet site requirements. The deadstart file is
on a reel of magnetic tape or a disk pack and contains the
programs necessary to establish the operating system and
its products (such as BASIC, FORTRAN, COMPASS, and so
forth)
on the system equipment. The same deadstart file
can be used for any supported equipment configuration.
In general, the procedure you use most often to deadstart is
warmstart. Warmstart from mass storage or a 667/669
magnetic tape unit is possible after the disk controller or
tape controller to be used is loaded with the proper
controlware and the controlware
is functioning. Warmstart
is always possible from 677/679 tape units.
There are three preliminary procedures that might be
required before performing
warmstart.
1. Coldstart
2.
Loads the tape and/or disk controlware to their
respective controllers.
Loading CTI module to disk
Loads the common
testing and initialization (CTI)
module to disk. Doing this procedure enables you
to perform warmstart from mass storage and to
run
the off-line maintenance system.
3. Loading DDS module to disk
Loads the
deadstart diagnostic sequencer (DDS)
module to disk. Doing this procedure enables you
to run the
DDS tests at deadstart time.
If
coldstart is required, you must do it before any other
procedure. Loading the CTI module and the DDS module to
disk
are optional procedures which each installation may
decide to perform in order to enable the
features they
provide.
I NOTE I
A ttempts to perform deadstart from mass
storage could be unsuccessful in
configurations with shared access to
controllers and drives. Conflicts can
arise
in both single and multiple mainframe
configurations. In a multimainframe
configuration, if another mainframe has
reserved the controller or drive,
deadstart
delays momentarily until the reservation
is released. In a single mainframe
configuration, if another channel has
reserved the drive,
deadstart will be
unsuccessful.
In this case, set the
deadstart panel for the other channel.
60435600 L
The following sUbsections explain
these procedures in more
detail. If the procedures
are not required, skip to the
subsection entitled Warmstart.
COLDSTART
The coldstart procedures outlined here load the tape and
disk controllers with
controlware. The tape controlware
can be loaded from a card reader or a tape unit depending
on the type
of controller.
The 7021 tape controller for a 667 or 669 tape unit requires
controlware loaded from a
card reader. The 7152 tape
controller requires controlware loaded from either a card
reader or a tape uni t.
The 7054 and 7154 disk controllers require controlware
loaded from a
card reader. The controlware for a 7152 disk
controller and
the 7155 disk controller (844-4x and 885 disk
drives) can be loaded from
either a card reader or a disk
unit.
The following paragraphs
summarize the procedures needed
to perform coldstart. You can use the appropriate
summary as a checklist during deadstart. Detailed
descriptions of all procedures in the deadstart process are
provided throughout the remainder of this section.
This manual assumes that power is applied on all required
equipment and
that the equipment is functioning properly.
If at any time the system loses power or the equipment
fails, consult the
site analyst or customer engineer.
COLDSTART OF CONTROLLERS FOR 667 OR
669 TAPE UNITS
Coldstart is necessary when deadstarting from 667 or 6691
magnetic tape units if the controlware has not yet been
loaded
to the controller. The coldstart procedure contains
a special program
that reads the tape controller
controlware, loads it to the controller, and then loads the
deadstart tape.
The following procedure, Coldstart 7021/7152 Tape
Controller from
Card Reader, can be used to load either
.the 7021 or the 7152 controller. The procedure coldstart
from tape unit can be used to load only the 7152 controller.
Use the warmstart procedure once the controlware has
been loaded and is functioning properly. Following
coldstart from a card reader, the system loads the
deadstart tape automatically, and warmstart is used for
subsequent
deadstarts only. However, following coldstart
from a tape unit, a warmstart must be performed to load
the system
deadstart tape.
It is advisable to reset the deadstart panel (refer to Setting
the Deadstart Panel) for a warmstart immediately after a
coldstart if the controlware has been loaded successfully.
After initial loading of the controlware, there is no reason
to p~rform a coldstart again if the tape subsystem is
operating
correctly.
2-1

I Coldstart 7021/7152 Tape Controller from Card Reader
The following steps summarize the procedures necessary to
coldstart a 7021 or 7152 tape controller from a card
reader. Use this as a checklist during coldstart. Ensure
that the tape unit on which the deadstart tape is to be
mounted and the
card reader are on different channels.
The card
reader must be on a channel without a PP (for
example, channel
12 or 13).
I
I
I
1. Ensure that required mass storage devices have
packs mounted and/or
are available.
2. Mount the deadstart tape (refer to appendix D
for operating instructions).
a. Ensure that the write enable ring is not on
the reel.
b. Mount the tape and ready the unit.
3. Set the deadstart panel for a coldstart from a
card reader (refer to figure 2-3). Set MODE
switch to LOAD.
4. Press the deadstart switch.
5. Insert card deckt in card reader and activate
card reader as follows:
a. Press
MOTOR POWER.
b. Select AUTO MODE.
c. Press RELOAD MEMORY.
d. Press READY.
6. Continue with the deadstart process by selecting
CTI options as described under Selecting CTI
Initial Options (*A*) Display later in this section.
I Cold.tort 7152 Tope Controller from Tope Unit
I
The following steps summarize the procedures necessary to
coldstart a 7152 tape controller from a 669 tape unit.
(Coldstart from a 667 tape unit is not possible.) Use this as
a checklist during coldstart. Ensure that the 669 tape unit
is
set to a unit number between 10 and 17. The unit must
be
on a channel without a PP (for example, channel 12 or
13).
1. Mount the controlware tape on the tape unit to
be specified on the deadstart panel (refer to
appendix D for operating instructions).
a. Ensure that write enable ring is not on reel.
b. Mount the
tape and ready the unit.
2. Set the deadstart panel for a coldstart from tape
unit (refer to figure 2-4). Set MODE switch to
LOAD.
3. Press the deadstart switch. No display appears
on the console. Unloading of the controlware
tape indicates the controlware has been loaded
successfully.

COLDSTART OF DISK CONTROLLERS FOR 844 OR
885 DISK UN ITS
Coldstart is necessary when deadstarting from 884 or 885
disk units if the controlware has not yet been loaded to the
controller. The coldstart procedure contains a special
program
that reads the disk controller control ware, loads it
to the controller, and then loads the deadstart file.
The following procedure, Coldstart 7054/7154/7152/7155
Disk
Controller from Card Reader, can be used to load all
disk controllers.
If the maintenence software library (MSL)
is available at your si te, the next procedure, Coldstart
7152/7155 Disk Controller from Disk Unit, can be used to
load the 7152 disk controller and the 7155 disk controller.
Use the warmstart procedure once the controlware has
been loaded and is functioning properly.· Following
coldstart from a card reader, the system loads the
deadstart tape automatically, and warmstart is used for
subsequent
deadstarts only.
It is advisable to reset the deadstart panel (refer to Setting
the Deadstart Panel) for a warmstart immediately after a
coldstart if the controlware has been loaded successfully.
After initial loading of the controlware, there is no reason
to perform a colds tart again if the disk subsystem is
operating correctly.

The following steps summarize the procedures necessary to
coldstart a disk controller from a card reader. Use this as I
a checklist during coldstart. Ensure that the card reader
and disk unit on which the deadstart device is mounted are
on different channels. The card reader must be on a
channel without a PP (for example, channel
12 or 13).
1. Ensure that required mass storage devices have
packs mounted and/or
are available.
2. Mount the deadstart disk unit if using an 844 disk
unit (refer to appendix D for operating
instructions).
3. Set the deadstart panel for a colds tart from a
card
reader using 844 or 885 disk units (refer to I
figure 2-5). Set MODE switch to LOAD.
4. Press the deadstart switch.
5. Insert card deckt in card reader and activate I
card reader as follows:
a. Press
MOTOR POWER.
b. Select AUTO MODE.
c. Press RELOAD MEMORY.
d. Press READY.
6. Continue with the
deadstart process by selecting
CTI options as described under Selecting CTI I
