The OpenVMS Alpha Galaxy Guide assumes that readers are familiar with OpenVMS concepts and operation, and it does not cover basic OpenVMS information.

How to Use this Book

The OpenVMS Alpha Galaxy Guide contains the following four parts:

Compaq recommends that you read Part I to learn about OpenVMS Galaxy concepts, features, benefits, configuration alternatives, and licensing information.

When you are ready to set up an OpenVMS Galaxy computing environment, read the chapter in Part II that is appropriate to your system. Be sure to refer to Chapter 10 to learn additional information that might be useful for your environment.

When your OpenVMS Galaxy system is running, see Part III for information about how to manage and use it.

If you want to develop applications that take full advantage of OpenVMS technology, see Part IV. Note that Appendix A is an example program that demonstrates many of the programming interfaces referenced in Part IV.

Conventions

In this manual:

The following conventions are used in this manual:
Ctrl/ x A sequence such as Ctrl/ x indicates that you must hold down the key labeled Ctrl while you press another key or a pointing device button.
PF1 x A sequence such as PF1 x indicates that you must first press and release the key labeled PF1 and then press and release another key or a pointing device button.
[Return] In examples, a key name enclosed in a box indicates that you press a key on the keyboard. (In text, a key name is not enclosed in a box.)

In the HTML version of this document, this convention appears as brackets, rather than a box.

... A horizontal ellipsis in examples indicates one of the following possibilities:
  • Additional optional arguments in a statement have been omitted.
  • The preceding item or items can be repeated one or more times.
  • Additional parameters, values, or other information can be entered.
.
.
.
A vertical ellipsis indicates the omission of items from a code example or command format; the items are omitted because they are not important to the topic being discussed.
( ) In command format descriptions, parentheses indicate that you must enclose the options in parentheses if you choose more than one.
[ ] In command format descriptions, brackets indicate optional elements. You can choose one, none, or all of the options. (Brackets are not optional, however, in the syntax of a directory name in an OpenVMS file specification or in the syntax of a substring specification in an assignment statement.)
[|] In command format descriptions, vertical bars separating items inside brackets indicate that you choose one, none, or more than one of the options.
{ } In command format descriptions, braces indicate required elements; you must choose one of the options listed.
bold text This text style represents the introduction of a new term or the name of an argument, an attribute, or a reason.
italic text Italic text indicates important information, complete titles of manuals, or variables. Variables include information that varies in system output (Internal error number), in command lines (/PRODUCER= name), and in command parameters in text (where dd represents the predefined code for the device type).
UPPERCASE TEXT Uppercase text indicates a command, the name of a routine, the name of a file, or the abbreviation for a system privilege.
Monospace text Monospace text indicates code examples and interactive screen displays.

In the C programming language, monospace type in text identifies the following elements: keywords, the names of independently compiled external functions and files, syntax summaries, and references to variables or identifiers introduced in an example.

- A hyphen at the end of a command format description, command line, or code line indicates that the command or statement continues on the following line.
numbers All numbers in text are assumed to be decimal unless otherwise noted. Nondecimal radixes---binary, octal, or hexadecimal---are explicitly indicated.

OpenVMS Galaxy Version 7.2--1 Release Notes

This chapter contains OpenVMS Galaxy release notes for OpenVMS Version 7.2--1 and notes from OpenVMS Version 7.2 that still apply to this release.

1.1 OpenVMS Galaxy Support on AlphaServer GS60/GS60E/GS140 Systems

V7.2--1 Release Note

OpenVMS Alpha Version 7.2--1 provides support for OpenVMS Galaxy configurations on AlphaServer GS60, GS60E, and GS140 systems.

For information about creating OpenVMS Galaxy computing environments on GS60, GS60E, and GS140 systems, see Chapter 5. Note that console firmware requirements for these systems is also included in this chapter.

OpenVMS Galaxy console firmware for AlphaServer 8400, 8200, and 4100 systems is located on the Alpha Systems Firmware Update Version 5.4 CD-ROM that is included with the OpenVMS Alpha Version 7.2--1 CD-ROM package.

For OpenVMS Alpha Version 7.2, OpenVMS Galaxy firmware files were included on the OpenVMS Alpha Version 7.2 kit.

1.4 OpenVMS Galaxy Operating Hints

V7.2--1 Release Note

Chapter 10 contains operating hints that OpenVMS Engineering has found useful in creating and supporting OpenVMS Galaxy environments.

1.5 Changes to the OpenVMS Alpha Galaxy Guide

V7.2--1 Release Note

This section describes OpenVMS Galaxy documentation changes and enhancements since OpenVMS Version 7.2.

1.5.1 KFE72-DA Installation Procedures Added

The procedures that describe how to install KFE72-DA modules in OpenVMS Galaxy systems have been expanded. For the correct procedures, see Chapter 6.

1.5.2 Additional SDA Information Published

The System Dump Analyzer (SDA) Galaxy-specific documentation in this book has been enhanced to include:

1.5.3 Running the CPU Load Balancer Program

Instructions for running the CPU load balancer program from the Galaxy Configuration Utility have been made more visible in Appendix A, and a new section about running the load balancer has been added to Chapter 10.

1.5.4 Enhancements to Galaxy-specific System Services Documentation

As of OpenVMS Version 7.2--1, documentation for the following Galaxy-specific systems services is included in DCL online help:

1.6 MOP Booting Restrictions

V7.2 Release Note

In an OpenVMS Galaxy computing environment, MOP Booting is only supported on Instance 0. This restriction will be removed in a future release.

1.7 Restriction on KFMSB and CIXCD Adapters in Galaxy Configurations

Permanent Restriction

Due to firmware addressing limitations on driver-adapter control data structures, KFMSB and CIXCD adapters can only be used on hardware partitions based at physical address (PA) = 0. In OpenVMS Galaxy configurations, this restricts their use to instance 0.

1.8 Compatibility of Galaxy Computing Environment and Non-Galaxy Cluster Members

V7.2 Release Note

OpenVMS Version 7.2 introduces new security classes that are used in an OpenVMS Galaxy computing environment. The new security classes are not valid on non-Galaxy systems. If your OpenVMS Galaxy is configured in an existing OpenVMS Cluster, you must ensure that all the nodes in the cluster recognize the new security classes as described in this release note.

This situation applies if all of the following conditions are met:

OpenVMS VAX and Alpha systems running OpenVMS Version 6.2 or Version 7.1 will crash if they encounter an unknown security class in the VMS$OBJECTS.DAT file.

To allow VAX and Alpha systems running older versions of OpenVMS to cooperate with Version 7.2 Galaxy instances in the same OpenVMS Cluster environment, a SECURITY.EXE image is provided for each of these versions. The appropriate remedial kit from the following list must be installed on all system disks used by these systems. (Later versions of these remedial kits may be used if available.)
Alpha V7.1 and V7.1-1xx ALPSYSB02_071
Alpha V6.2 and V6.2-1xx ALPSYSB02_062
VAX V7.1 VAXSYSB01_071
VAX V6.2 VAXSYSB01_062

Before you create any galaxywide global sections, you must reboot all cluster members sharing one of the updated system disks.

See Section 3.7.1 the installation questions that relate to this topic.
