About This Guide

This guide describes how to perform routine system hardware operations for HP Integrity NonStop NS-series servers on H-series release version updates.

This guide is primarily geared toward commercial type NonStop NS-series servers (see Differences Between Integrity NonStop NS-Series Systems on page 2-2 for high- level architectural and hardware differences between the various commercial models). While basic monitoring principles, such as Using OSM to Monitor the System on page 3-7, apply to Telco as well as commercial systems, refer to the NonStop NS-Series Carrier Grade Server Manual for hardware details and service procedures specific to Telco systems.

Note. NS-series refers to the hardware that makes up the server. H-series refers to the software that runs on the server.

The term, NonSto p s erv er, refers to both NonStop S-series servers and Integrity NonStop NS-series servers.

For comprehensive information about performing operations tasks for an Integrity NonStop NS-series server, you need both this guide and the Guardian User’s Guide. The Guardian User’s Guide describes some tasks not covered in this guide, such as supporting users of the system.

The Guardian User’s Guide describes routine tasks common to system operations on all NonStop servers. Instructions and examples show how to support users of the system, how to monitor operator messages, how to control the spooler, and how to manage disks and tapes. Numerous tools that support these functions are also documented. Some monitoring procedures in the Guardian User’s Guide have information about using only the Subsystem Control Facility (SCF). That guide does not generally describe any monitoring procedures using the OSM packages.

Where to Get More Info rma tion

Information about the use of OSM, such as how to migrate from TSM to OSM, how to install and configure OSM server and client components, and how to use the OSM Service Connection, appear in these manuals:

Servers that are connected in ServerNet clusters require special installation and operating procedures that are not documented in this manual. Such information is instead provided with the appropriate cluster documentation and the ServerNet Cluster Supplement for Integrity NonStop NS-Series Servers.

In the 6780 ServerNet cluster environment, installation and operating procedures are documented in these manuals:

•

ServerNet Cluster 6780 Operations Guide

•

Installation and operating procedures for earlier server clusters (those using 6770 switches) are documented in:

About This Guide

OSM is the required system management tool for servers that use 6780 switches in ServerNet clusters, but OSM also provides system management for earlier versions of ServerNet clusters.

$process-name.#su-name

Line Spacing. If the syntax of a command is too long to fit on a single line, each

continuation line is indented three spaces and is separated from the preceding line by a blank line. This spacing distinguishes items in a continuation line from items in a vertical list of selections. For example:

ALTER [ / OUT file-spec / ] LINE [ , attribute-spec ]…

Notation for Messages

The following list summarizes the notation conventions for the presentation of displayed messages in this manual.

Bold Text. Bold text in an example indicates user input entered at the terminal. For

example:

ENTER RUN CODE ?123 CODE RECEIVED: 123.00

Notation for Messages

The user must press the Return key after typing the input.

Nonitalic text. Nonitalic letters, numbers, and punctuation indicate text that is displayed or

returned exactly as shown. For example:

Backup Up.

lowercase italic letters. Lowercase italic letters indicate variable items whose values are

displayed or returned. For example:

p-register process-name

[ ] Brackets. Brackets enclose items that are sometimes, but not always, displayed. For

example:

Event number = number [ Subject = first-subject-value ]

A group of items enclosed in brackets is a list of all possible items that can be displayed, of which one or none might actually be displayed. The items in the list might be arranged either vertically, with aligned brackets on each side of the list, or horizontally, enclosed in a pair of brackets and separated by vertical lines. For example:

proc-name trapped [ in SQL | in SQL file system ]

{ } Braces. A group of items enclosed in braces is a list of all possible items that can be

displayed, of which one is actually displayed. The items in the list might be arranged either vertically, with aligned braces on each side of the list, or horizontally, enclosed in a pair of braces and separated by vertical lines. For example:

obj-type obj-name state changed to state, caused by { Object | Operator | Service }

process-name State changed from old-objstate to objstate { Operator Request. } { Unknown. }

| Vertical Line. A vertical line separates alternatives in a horizontal list that is enclosed in

brackets or braces. For example:

Transfer status: { OK | Failed }

% Percent Sign. A percent sign precedes a number that is not in decimal notation. The

% notation precedes an octal number. The %B notation precedes a binary number. The %H notation precedes a hexadecimal number. For example:

%005400 %B101111 %H2F P=%p-register E=%e-register

Determining the Cause of a Problem: A Systematic Approach

Continuous availability of your NonStop system is important to system users, and your problem-solving processes can help make such availability a reality. To determine the cause of a problem on your system, start by trying the easiest, least expensive possibilities. Move to more complex, expensive possibilities only if the easier solutions fail.

This subsection presents an approach you can use in your operations environment to:

Determine the possible causes of problems

•

Systematically fix or escalate such problems

•

Develop ways of preventing the same problems from recurring

•

The four basic steps in systematic problem solving are:

Task Page

Task 1: Get the Facts Task 2: Find and Eliminate th e C ause of the Problem 1-7 Task 3: Escalate the Problem If Necessary 1-8 Task 4: Prevent Future Problems 1-9

A Problem-Solving Worksheet

Table 1-1 is a worksheet that you can use to help you through the problem-solving

process. Use this worksheet to:

Get the facts about a problem

•

Find and eliminate the cause of the problem

•

Make any appropriate escalation decisions

•

Prevent future problems

•

Introduction to Integrity NonStop NS-Series Operations

Task 1: Get the Facts

The first step in solving any problem is to get the facts. Although it is tempting to speculate about causes, your time is better spent in first understanding the symptoms of the problem.

Task 1a: Determine the Facts About the Problem

To get a clear, complete description of problem symptoms, ask questions to determine the facts about the problem. For example:

Category Questi ons to Ask

What? What are you having trouble with?

What specifically is wrong?

Where? Where did you first notice the problem?

Where has it occurred since you first noticed it?

Which ap plic ations, components, de v ic es , and people ar e affec t ed?

When? When did the problem occur?

What is the frequency of the problem?

Has this problem occurred before this time?

Task 1: Get the Facts

Magnitude? Is the problem quantifiable in any way? (That is, can it be measured?) For

example , h ow m any people are affected? Is this problem getting wors e?

Task 1b: Determine the Facts About the Situation

Collect facts about the situation in which the problem arose. A clear description of the situation that led to the problem could indicate a simple solution. Examples of questions to ask are:

Who reported the problem and how can this person be contacted?

•

How critical is the situation?

•

What events led to the problem?

•

Has anything changed recently that might have caused the problem?

•

What event messages have you received?

•

What is the current configuration of the hardware and software products affected?

•

An example of information you might obtain from asking questions:

Question Answer

What is happening that indicates a problem?

Where is this problem occurring?

A terminal is h ung.

In the office of USER.BONNIE. The affected terminal is named $JT1.#C02.

When is this problem occurring? At 8:30 this morning and also at the same time two days

ago. Both times, this problem occurred after three unsuccessful attempts to log on.

What is the magnitude of this problem?

HP Integrity NonStop NS-Series Operations Guide—529869-005

Intermittent; the problem seemed t o disappear on its own when it first occurred two days ago.
