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.

Use this guide along with the Guardian User’s Guide and the written policies and procedures of your company regarding:

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:

•

OSM Service Connection User’s Guide (available in NTL and as online help within

•

the OSM Service Connection)

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 Planning and Installation Guide

•

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.

error := NEXTFILENAME ( file-name ) ; LISTOPENS SU $process-name.#su-name

Quotation marks around a symbol such as a bracket or brace indicate the symbol is a required character that you must enter as shown. For example:

"[" repetition-constant-list "]"

Item Spacing. Spaces shown between items are required unless one of the items is a

punctuation symbol such as a parenthesis or a comma. For example:

CALL STEPMOM ( process-id ) ;

If there is no space between two items, spaces are not permitted. In the following example, there are no spaces permitted between the period and any other items:

$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

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

About This Guide

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

•

1-6

Make copies of this worksheet and use it to collect and analyze facts regarding a problem you are experiencing. The results might not tell you exactly what is occurring, but they will narrow down the number of possible causes.

You are authorized by HP to reproduce this worksheet only for the purpose of operating your system.

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.

1-6

Page 31

Introduction to Integrity NonStop NS-Series Operations

Task 2: Find and Eliminate the Cause of the Problem

After you collect the facts, you are ready to begin considering the possible causes of a problem. Using these facts and relying on your knowledge and experience, begin to list possible causes of the problem.

Task 2a: Identify the Most Likely Cause

To evaluate the possible causes of any problem, you must compare each cause with the problem symptoms. The problem-solving worksheet gives you a guide for accomplishing this task. In the following example:

Possible causes become column headings

•

Entries made in the worksheet’s rows indicate whether the cause in that column

•

could have produced the problem symptoms you listed in that row.

Write yes in the appropriate box if that cause could explain that symptom.

Write no in the appropriate box if a possible cause does not explain a fact.

The most likely cause is the one that best explains all the facts; that is, the cause that contains the most yes answers.

For example, possible causes of a hung terminal problem could be:

A terminal hardware problem

•

A stopped or suspended TACL process

•

System security, which locks a user out after three unsuccessful logon attempts

•

This worksheet lists some possible causes of a hung terminal and illustrates further how to evaluate the possible causes:

Problem Facts Possible Causes

What? Terminal $JT 1. #C 02 is hung Yes Yes Yes

Where? Office of USER.BONNIE Yes Yes Yes

Page 32

Introduction to Integrity NonStop NS-Series Operations

Task 3: Escalate the Problem If Necessar y

Task 2b: Fix the Most Probable Cause of the Problem

For the example in the worksheet, the most likely cause of the hung terminal is a security problem. Ask yourself what would be the fastest, least expensive, safest, and surest way of verifying that this is the most probable cause of the problem.

Once you have determined the most likely cause, try to fix it. Follow through and implement the appropriate solution. If this solution does not fix the problem, continue trying other possible solutions that are reasonable considering time, expense, and safety.

Task 3: Escalate the Problem If Necessary

If the solutions you tried in the previous tasks do not solve the problem, you might consider escalating the problem to get additional help.

Task 3a: Determine Whether You Need to Escalate the Problem

After you complete each task i n the pro blem- solvi ng pro cess, you must decide whe ther you can continue by yourself or if you must ask for help. Ask yourself these questions:

Do I have the authority to resolve this problem?

•

Do I have the necessary knowledge?

•

Do I have the skill?

•

Do I have the time?

•

What other people need to become involved, if any?

•

Who needs to be informed about the problem’s status?

•

Task 3b: Provide Documentation

If you decide to escalate the problem, you might be required to document the problem by providing:

A problem identification number

•

A problem classification

•

A complete description and history of the problem

•

Diagnostic information such as copies of the event log, results of memory dumps,

•

and so on

You might also have procedures at your site for logging problems. If you have a shift log or problem log, make timely entries in the log.

Introduction to Integrity NonStop NS-Series Operations

Task 4: Prevent Future Problems

Solving problems that occur with your system can be exciting because it is active and stimulating. Preventing problems is often less dramatic. But in the end, prevention is more productive than solving problems. The more work you do to prevent problems before they arise, the fewer problems that will arise at potentially critical times.

These questions provide a framework for your problem-prevention efforts:

Why did this problem occur? What was the root cause? Were there any

•

contributing causes? How serious was the problem?

•

What is the likelihood that it will occur again?

•

Is it possible to eliminate the causes of this problem?

•

Is it possible to reduce the likelihood that this problem will occur in the future?

•

Can automation tools be used to detect and respond to preliminary symptoms of

•

this problem?

Task 4: Prevent Future Problems

Can anything be done now to minimize the damage that would result from a

•

reoccurrence of this problem? Can the problem resolution process be improved in any way?

•

Logging On to an Integrity NonStop Server

Many operations and troubleshooting tasks are performed by logging on to your Integrity NonStop server from a system console and using the TACL command interpreter or one of the OSM applications. For example, the TACL command interpreter allows you to access SCF, which you use to configure, control, and collect information about objects within subsystems. For examples of OSM tasks and functions, see Overview of OSM Applications

System Consoles

A system console is a personal computer approved by HP to run maintenance and diagnostic software for Integrity NonStop servers. New system consoles are preconfigured with the required HP and third-party software. When upgrading to the latest RVU, software upgrades can be installed from the HP NonStop System Console Installer CD.

on page 1-11.

System consoles comm uni cate with Inte gri ty Non Stop servers over a ded icated se rvi ce LAN (local area network). System consoles configured as the primary and backup dialout points are referred to as the primary and backup system consoles, respectively.

The OSM Low-Level Link and OSM Notification Director applications reside on the system console, along with other required HP and third-party software. OSM Service Connection and OSM Event Viewer software resides on your server, and connectivity

is established from the console through Internet Explorer browser sessions. For more information, see Launching OSM Applications on page 1-11.

Opening a TACL Window

On a system console, you must open a TACL window before you can log on to the TACL command interpreter. For information about logging on to a TACL command interpreter, see the Guardian User’s Guide.

You can use any of the following methods to open a TACL window.

Opening a TACL Window Directly From OutsideView

If you know the IP address of the NonStop server (not that of OSM), use this method:

1. Select St art> Pro gram s>OutsideV iew32 7.1.

2. From the Session menu, select New. The New Session Properties dialog box

appears.

Opening a TACL Window

3. From the New Session Properties dialog box, Session tab, click IO Properties.

The TCP/IP Properties dialog box appears.

4. In the TCP/IP Properties dialog box:

a. In the Host name or IP address and port box, type the IP address, followed by

a space and the port number. For example:

172.17.22.187 23

The port number is 23 for a TACL prompt and 301 for a Startup TACL prompt. In general, you should use port number 23 to perform operations tasks.

b. Click OK.

5. From the New Session Properties dialog box, click OK. A TACL window appears.

6. Log on to the TACL prompt.

Opening a TACL Window From the Low-Level Link

You can also open a TACL window from the OSM Low-Level Link application as described in the Troubleshooting section in Opening Startup Event Stream and Startup

TACL Windows on page 15-22.

For more details on the functions of the TACL command interpreter, see Appendix B,

Tools and Utilities for Operations.

Overview of OSM Applications

HP NonStop Open System Management (OSM) applications perform a variety of functions, such as:

The OSM Low-Level Link Application is primarily used for down-system support,

•

such as Two startup event stream windows and two startup TACL windows are

automatically launched on the system console configured to receive them. on

page 15-6, Recovery Operations for Processors on page 9-9, and configuring IOAM, VIO, and P-switch modules (see the NonStop NSxxxx Hardware Installation Manual for your Integrity NonStop NS16000, NS14000, or NS1000 server).

The OSM Service Connection is used to monitor, inventory, and perform actions

•

on system and ServerNet Cluster components. See Using OSM to Monitor the

System on page 3-7 for an overview of how the OSM Service Connection is used

to monitor your system components. The OSM Event Viewer is used for Section 4, Monitoring EMS Event Messages.

•

The OSM Notification Director is used for Monitoring Pr oblem Inci dent Reports on

•

page 3-12 and dialing out information to your service provider.

Overview of OSM Applications

Launching OSM Applications

Several operations tasks in this guide require you to log on to one of the OSM applications. Assuming that all OSM client components have been installed on the system console, launch the desir ed ap plication as d escribed below, then see the online help (or default home page, for the browser-based OSM applications) for log-on instructions.

To launch OSM applications: Start>Pr ogram s> HP OSM. Then select the name of the application to launch:

OSM Service Connection

•

OSM Low-Level Link Application

•

OSM Notification Director>Start/Stop

•

OSM Event Viewer

•

OSM System Inventory Tool

•

The OSM Service Connection and the OSM Event Viewer are browser-based applications. Assuming that the OSM Console Tools component has been installed on the system console, the Start menu shortcuts launch a default web page for these two applications. From that page, you can select the system of your choice from the list of bookmarks displayed in the left column of the page (available bookmarks include those that were user-created during previous sessions and those converted automatically from an existing OSM system list). If no bookmarks are available, the web page also contains instructions on how to access these a pplications by e nterin g a system URL as an Internet Explorer address. The system console-based OSM Console Tools component is not required to use the OSM Service Connection and the OSM Event

Differences Between Integrity NonStop NS-Series Systems

NonStop System Architectures

Integrity NonStop NS-series systems offer of a variety of architecture and configuration options to suit different customer needs. Integrity NonStop NS16000 and Integrity NonStop NS14000 systems take advantage of NonStop advanced architecture (NSAA). For more information, see the NonStop NS16000 Planning Guide or NonStop NS14000 Planning Guide. Integrity NonStop NS1000 systems employ the NonStop value architecture (NSVA). For more information, see the NonStop NS1000 Planning Guide.

Integrity NonStop NS16000 Systems

In Integrity NonStop NS16000 systems, IOAM enclosures connect through ServerNet links to the processors via the processor switches. One IOAM enclosure provides ServerNet connectivity for up to 10 ServerNet I/O adapters on each of the two ServerNet fabrics. FCSAs and G4SAs can be installed in an IOAM enclosure for

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

2-2

Page 39

Determining Your System Configuration

communications to storage devices and subsystems as well as to LANs. Additional IOAM enclosures can be added to increase connectivity and storage resources.

Integrity NonStop NS16000 systems connect to NonStop S-series I/O enclosures by using fiber-optic ServerNet links to connect the p-switches of the Integrity NonStop system to IOMF2 CRUs in the I/O enclosures.

Integrity NonStop NS14000 Systems

In Integrity NonStop NS14000 systems, there are no p-switches. There are now two types of NS14000 systems:

A NonStop NS14000 system consisting of a single IOAM enclosure, with an I/O

•

adapter module on each ServerNet fabric — processor connections are made

through ports on 4-Port ServerNet Extenders (4PSEs), located in slot one and

optionally slot 2 of each I/O adapter module, to the processors via the LSUs. The

IOAM enclosure provides ServerNet connectivity for up to 8 ServerNet I/O

adapters on each of the two S erve rNet fab rics (FC SAs and G4SAs can be inst al led

in slots 2 through 5 of the two IOAMs in the IOAM enclosure for communications to

storage devices and subsystems as well as to LANs). Integrity NonStop NS14000

systems do not support connections to additional IOAM enclosures or NonStop

S-series I/O enclosures.

Differences Between Integrity NonStop NS-Series

Systems

A NonStop NS14000 system consisting of two VIO enclosures, one on each

•

ServerNet fabric — processor connections for processors 0-3 are made through

ports 1-4 of the VIO Logic Board in slot 14 of each VIO enclosure, via the LSUs.

An optional Optical Extender PIC in slot 2 provides for additional processor

connectivity (processors 4-7). VIO enclosures have embedded ports and allow for

optional expansion ports to supply the equivalent functionality provided by FCSAs

and G4SAs in NS14000 systems with IOAMs. Integrity NonStop NS14000 systems do not support connections to additional IOAM

enclosures or NonStop S-series I/O enclosure For more information on Integrity NonStop NS14000 systems, see the Versatile I/O

(VIO) Manual, the NonStop NS14000 Planning Guide, or the NonStop NS14000 Hardware Installation Manual.

Integrity NonStop NS1000 Systems

Integrity NonStop NS1000 systems have no processor switches or LSUs. Like Integrity NonStop NS14000 systems, there are now two types: those consisting of a single IOAM enclosure (two IOAMs) and those consisting of one VIO enclosure for each fabric. ServerNet connectivity for each type is accomplished as described for the

Integrity NonStop NS14000 Systems, except for the absence of the LSUs.

Integrity NonStop NS1000 systems do not support connections to NonStop S-series I/O enclosures. Besides the architectural differences, Integrity NonStop NS1000 systems also utilize different NonS t op Bl ade Element s t han I ntegr ity NonStop NS16000 or NS14000 systems. For more information on Integrity NonStop NS1000 systems, refer to the NonStop NS1000 Planning Guide and the NonS top NS10 00 Hardware Installation Manual.

Terms Used to Describe System Hardware

Terms Used to Describe System Hardware Components

The terms used to describe system hardware components vary. These terms include:

Device

•

System resource or object

•

Device

A device can be a physical device or a logical device. A physical device is a physical component of a computer system that is used to communicate with the outside world or to acquire or store data. A logical device is a process used to conduct input or output with a physical device.

System Resource or Object

The term “system resource” is used in OSM documentation to refer to server components that OSM software displays, monitors, and often controls. The term “object” is often used when referring to a specific resource, such as “the Disk object.” All system resources are displayed in hierarchical form in the tree pane of the OSM Service Connectio n; man y are also d isplayed in P hysical or In ventor y view s of the view pane. The effe ct of sele cting an object in ei ther pa ne is the same: for example, you can view attributes for the selected system resource in the Attributes tab, view alarms for that resource (if any exist) in the Alarms tab, or right-click on the resource object and select Actions, to display the Actions dialog box (from which you can select and perform actions on the selected system resource). Besides physical hardware components, such as IOAM enclosures, power supplies, ServerNet adapters, and disk and tape drives, system resources also include logical entities that OSM supports, such as logical processors, ServerNet fabrics, and LIFs (logical interfaces).

Components

Recording Your System Configuration

As a system operator, you need to understand how your system is configured so you can confirm that the hardware and system software are operat ing norma lly. If problems do occur, knowing your configuration allows you to pinpoint problems more easily. If your system configuration is corrupted, documentation about your configuration is essential for recovery. You should be familiar with the system organization, system configuration, and naming conventions.

Several methods are available for researching and recording your system configuration:

Maintaining records in hard-copy format

•

Using the OSM Service Connection to inventory your system

•

In the OSM Service Connection tree pane, select the System object. From the

View pane drop-down menu, select Inventory to display a list of the system’s

hardware resources. Click Save to save this list to a Microsoft Excel file.

Determining Your System Configuration

For information on forms available that can help you record your system configuration, refer to the NonStop NSxxxx Planning Guide for your Integrity NonStop NS16000, NS14000, or NS1000 server.

Using SCF to Determine Your System Configuration

SCF is one of the most important tools available to you as a system operator. SCF commands configure and control the objects (lines, controllers, processes, and so on) belonging to each subsystem running on the Integrity NonStop NS-series server. You also use SCF to display information about subsystems and their objects.

SCF accepts commands from a workstation, a disk file, or an application process. It sends display output to a workstation, a file, a process, or a printer. Some SCF commands are available only to some subsystems. An overall SCF reference is the SCF Reference Manual for H-Series RVUs. Subsystem-specific information appears in a separate manual for each subsystem. For a partial list of these manuals, refer to

Appendix C, Related Reading.

More detai ls about the functions o f SCF appear in Subsystem Control Facility (SCF) on

page B-4.

SCF System Naming Conventions

SCF object names usually follow a consistent set of naming conventions defined for each installation. HP preconfigures some of the naming conventions to create the logical device names for many SCF objects.

System planning and configuration staff at your site likely will change or expand on the preconfigured file-naming conventions that HP provides, typically by establishing naming conventions for configuring such objects as storage devices, communication processes, and adapters. These conventions should simplify your monitoring tasks by making process or object functions intuitively obvious to someone looking at the object name. For example, in your environment, tape drives might be named $TAPEn, where n is a sequential number.

The SCF Reference Manual for H-Series RVUs lists naming conventions for SCF objects, as well as HP reserved names that cannot be changed or used for other objects or processes in your environment.

SCF Configuration Files

Your system is delivered with a standard set of configuration files:

The $SYSTEM.SYSnn.CONFBASE file contains the minimal configuration

•

required to load the system.

The $SYSTEM.ZSYSCONF.CONFIG file contains a standard system configuration

•

created by HP. This basic configuration includes such objects as disk drives, tape

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

2-5

Page 42

Determining Your System Configuration

drives, ServerNet adapters, the local area network (LAN) and wide area network

(WAN) subsystem manager processes, the OSM server processes, and so on.

You typically use this file to load the system.

The $SYSTEM.ZSYSCONF.CONFIG file is also saved on your system as the

•

ZSYSCONF.CONF0000 file. All subsequent changes to the system configuration are made using SCF. The system

saves configuration changes on an ongoing basis in the ZSYSCONF.CONFIG file. You have the option to save a stable copy of your configuration at any time in ZSYSCONF.CONFxxyy using the SCF SAVE command. For example:

-> SAVE CONFIGURATION 01.02

You can save multiple system configurations by numbering them seq uentially ba sed on a meaningful convention that reflects, for example, different hardware configurations. Each time you load the system from CONFBASE or CONFxxyy, the system automatically saves in a file called ZSYSCONF.CONFSAVE a copy of the configuration file used for the system load.

Using SCF to Display Subsystem Configuration

Information

For guidelines on how to recover if your system configuration files are corrupted, refer to Troubleshooting and Recovery Operations on page 15-18.

For certain SCF subsystems, configuration changes are persistent. The changes persist through processor and system loads unle ss you load the system with a dif ferent configuration file. Examples of these subsystems are the Kernel, ServerNet LAN Systems Access (SLSA), the storage subsystem, and WAN. For other SCF subsystems, the changes are not persistent. You must reimplement them after a system or processor load. Examples of these subsystems are General Device Support (GDS), Open System Services (OSS), and SQL communication subsystem (SCS).

Using SCF to Display Subsystem Configuration Information

SCF enables you to display, in varying levels of detail, the configuration of objects in each subsystem supported by SCF. For example, you can use the LISTDEV command to list all the devices on your system or to list the objects within a given subsystem. Then you can use the INFO command with a logical device name or device type to obtain information about a specific device or class of devices.

Another useful command when displaying information is the ASSUME command. Use the ASSUME command to define a current default object and fully qualified object name. Then you can use INFO to display information just for that object. For example, if you type this command and then enter the INFO command without specifying an object, SCF displays only the information for the workstation called $Ll.#TERM1:

> SCF ASSUME WS $L1.#TERM1

Overview of Monitoring and Recovery

Functions of Monitoring

You must monitor a system to ensure that it is operating properly and to recognize when corrective action is required. By monitoring a system, you can:

Verify whether components are currently up or down

•

Be quickly notified of error conditions, state changes, and threshold conditions that

•

have been exceeded or are reaching their limits

View a chronological list of events that can help with problem diagnosis and

•

resolution

Determine how much of a particular resource is being used; for example,

•

processor capacity, disk or file space, or communications line bandwidth

Find performance problems that can affect the users of the system

•

Make better use of existing resources

•

Ensure that products such as HP NonStop SQL/MP, HP NonStop SQL/MX, HP

•

NonStop Transaction Management Facility (TMF), and Pathway are available

Functions of Monitoring

Prevent many problems and outages from occurring

•

Monitoring Tasks

Regardless of the shift you work, certain areas of your hardware and software environment need to be checked on a regular basis. This subsection provides guidelines that will enable you to determine the general areas you should monitor.

Working With a Daily Checklist

A good method for ensuring that certain areas of your operations environment are monitored is to develop a checklist. Monitor these items on a system frequently. At least daily, monitor:

OSM Service Connection GUI

•

Event messages

•

Alarms

•

Problem incident reports

•

The status of all system components

•

The status of processes

•

The status of all applications

•

The performance of processors, disks, and communications lines (Monitoring

•

performance is not discussed in this guide.)

Monitoring and Resolving Problems—An Approach

A useful approach to identifying and resolving problems in your system is to first use OSM to locate the focal point of a hardware problem and then use SCF to gather all the related data from the subsystems that control or act on the hardware. In this way, you can develop a larger picture that encompasses the whole environment, including communications links and other objects and services that might be contributing to the problem or affected by it.

To get comprehensive online descriptions of all the available SCF commands, use the SCF HELP command.

The following subsections give instructions for using OSM and SCF to monitor and resolve problems.

Using OSM to Monitor the System

This section deals mostly with the OSM Service Connection, the primary OSM interface for system monitoring and serviceability.

See Overview of OSM Applications on page 1-11 for examples of how the other OSM applications are used for monitoring-related functions.

Using the OSM Service Connection

The OSM Service Connection can be used in a variety of ways to monitor your system, including:

Use of colors and symbols to direct you to the source of any problems

•

Attribute values for system resources, displayed in the Attributes tab and in many

•

dialog boxes. Alarms, displayed in the Alarms tab and Alarm Summary dialog box.

•

The following section presents one model for using the OSM Service Connection to monitor your system, along with a few other options.

A Top-Down Approach

The Management (or main) window of the OSM Service Connection uses a series of colors and symbols to notify you that pr oblems exist within the system. You can tell at a high-level glance when problem conditions exist, then drill-down, or expand the tree pane to find the component reporting the problem. Figure 3-1 illustrates how both the the rectangular system icon (located at the top of the view pane) and the system object in the tree pane indicate problems within the system. The system icon, which is green when OSM is reporting no problems on the system, has turned yellow. The system icon in the tree pane is displaying a yellow arrow to indicate a problem within.

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

3-7

Page 60

Overview of Monitoring and Recovery

Figure 3-1. OS M Management: System Icons Indicate Problems Within

Using the OSM Service Connection

VST310.vsd

Note. In the OSM Service Connection Management window, the tree pane is located on the far left. In the lower right is the Overview pane. Located between them is the details pane, from which you can choose to view the Attributes or Alarms tab. Directly above the details pane is the view pane, from which you can choose a Physical or Inventory view of your system or ServerN et C lus t er. The gray bar directly above the view pane is an OSM -s pecific toolb ar (as opposed to the standard Internet Explorer menu bar at the top of the browser window).

Expanding the system object in the tree pane, you can see a yellow arrow on the Group 110 object, indicating that the problem is located somewhere within that group.

Expanding the tree pane further, as illustrated in Figure 3-2, yellow arrows on the IOAM Enclosure 110 and IOAM 110.3 objects reveal that the problem exists on a ServerNet adapter in slot 3 of that I/O module. The red bell-shaped icon by that resource object (in the tree pane) indicates that there is an alarm on the object. To obtain information about the alarm:

1. Click to select the object displaying the red triangular and bell-shaped symbols.

2. Select the Alarms tab from the details pane.

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

3-8

Page 61

Overview of Monitoring and Recovery

3. Click to select the alarm, then right-click and select Details.

Figure 3-2. Expanding the Tree Pane to Locate the Source of Problems

Using the OSM Service Connection

VST311.vsd

Check the Attributes tab (Figure 3-3) also, as a yellow or red triangular symbol indicates problem attribute values exist. In this case, the degraded Service State attribute was caused by an alarm. However, when a resource displays a yellow or red triangular object but no bell-shaped icon, it has no alarms but is reporting problem or degraded attribute values.

Using System Status Icons to Monitor Multiple Systems

When you are monitoring multiple systems, you can create a System Status Icon for each system, allowing you to keep a high-level eye on each system while saving screen space. Figure 3-4 shows three separate System Status icons, each created by:

1. Establishing an OSM Service Connection session to the system.

2. From the Summary menu on the OSM toolbar, selecting System Status. You can then minimize, but not close, the OSM Service Connection Management

window for each system. If the System Status icon for a system turns from green to yellow, as illustrated in Figure 3-4, open the Management window for that system and locate the problem as described in A Top-Down Approach on page 3-7.

Using Alarm and Problem Summaries

Other options for monitoring your system with the OSM Service Connection include using the Alarm Summary (Figure 3-5) or Problem Summary (Figure 3-6) dialog boxes to quickly view all alarms and problem conditions that exist on your system.

Overview of Monitoring and Recovery

Recovery Operations for Problems Detected by

Suppressing Problems and Alarms

In certain cases, you might want to acknowledge or suppress a particular problem, to stop it from propagating a known problem all the way up to the system level. That way, it will be easier to identify other problems that might occur. For more information on OSM problem management features such as deleting or suppressing alarms and suppressing problem attributes, see the OSM Service Connection User’s Guide (also available as online help within the OSM Service Connection).

Recovery Operations for Problems Detected by OSM

Recovery operations depend on the particular problem, of course. Methods of determining the appropriate recovery action include:

Alarm Deta ils, avai lable for each al arm displaye d i n O SM, pr ovide su ggested repair

•

actions. The value displayed by problem attributes in OSM often provide clues to recovery.

•

EMS events, retrieved and viewed in the OSM Event Viewer, include cause, effect,

•

and recovery information in the event details.

OSM

Check the section in this guide that covers the system resource—for example,

•

Section 11, Tape Drives: Monitoring and Recovery— for information on using the

SCF and other tools to determine the cause of a problem. Then follow the directions in the Recovery Operations subsection in the relevant section.

Replacing a system component that has malfunctioned is beyond the scope of this guide. For more information, contact your service provider, or refer to the Support and

Service Library on page 1-12.

Monitoring Problem Incident Reports

The OSM Notif ication D ire ctor g ener ates pr oblem i ncident r epor t s when changes occur that could directly affect the availability of resources on your Integrity NonStop server. The Incident Report List tab on the Notification Director dialog box allows you to view, sort, authorize, and reject incident reports. The Notification Director allows you to forward notifications to your service provider if your system is configured for remote dial-out.

Using SCF to Monitor the System

Use the Subsystem Control Facility (SCF) to display information and current status for all the devices on your system known to SCF. Some SCF commands are available only to some subsystems. The objects that each command affects and the attributes of those objects are sub system sp ecific. This subsystem -spe cific inform ation a ppear s in a separate manual for each subsystem. A partial list of these manuals appears in

Appendix C, Related Reading.

Determining Device States

This subsection explains how to determine the state of devices on your system. For example, to monitor the current state of all tape devices on your system, at an SCF prompt:

-> STATUS TAPE $*

Example 3-1 shows the results of the SCF STATUS TAPE $* command:

Example 3-1. SCF STATUS TAPE Command

Automating Routine System Moni toring

Automating Routine System Monitoring

You can automate many of the monitoring procedures. Automation saves you time and helps you to perform many routine tasks more efficiently.

Your operations environment might be using TACL macros, TACL routines, or command files to perform routine system monitoring and other tasks. These items allow you to run many procedures so that you can quickly determine system status, produce reports, or perform other common tasks. The TACL Reference Manual contains an example that you can adapt to automate system monitoring.

Example 3-2 contains an example of a command file you can use or adapt to check

many of the system elements:

1. To create a command file named SYSCHK that will automate system monitoring, type the text shown in Example 3-2 into an EDIT file.

Example 3-2. System Monitoring Command File

COMMENT THIS IS THE FILE SYSCHK COMMENT THIS CHECKS ALL DISKS: SCF STATUS DISK $* COMMENT THIS CHECKS ALL TAPE DRIVES: SCF STATUS TAPE $* COMMENT THIS CHECKS THE SPOOLER PRINT DEVICES: SPOOLCOM DEV COMMENT THIS CHECKS THE LINE HANDLERS: SCF STATUS LINE $* COMMENT THIS CHECKS THE STATUS OF TMF: TMFCOM;STATUS TMF COMMENT THIS CHECKS THE STATUS OF PATHWAY: PATHCOM $ZVPT;STATUS PATHWAY;STATUS PATHMON COMMENT THIS CHECKS ALL SACS: SCF STATUS SAC $* COMMENT THIS CHECKS ALL ADAPTERS SCF STATUS ADAPTER $* COMMENT THIS CHECKS ALL LIFS SCF STATUS LIF $* COMMENT THIS CHECKS ALL PIFS SCF STATUS PIF $*

2. After you create this file, at a TACL prompt, type this command to execute the file and automatically monitor many elements of your system:

> OBEY SYSCHK

For an example of the output that is sent to your home terminal when you execute a command file such as SYSCHK, refer to Example 3-3. This output shows that all elements of the system being monitored are up and running normally.

When to Use This Section

Use this section for a brief description of the Event Management Service (EMS) and the tools used to monitor EMS event messages.

What Is the Event Management Service (EMS)?

The Event Management Service (EMS) is a collection of processes, tools, and interfaces that support the reporting and retrieval of event information. Information retrieved from EMS can help you to:

Monitor your system or network environment

•

Analyze circumstances that led up to a problem

•

Detect failure patterns

•

Adjust for changes in the run-time environment

•

Recognize and handle critical problem s

•

Perform many other tasks required to maintain a productive computing operation

•

Tools for Monitoring EMS Event Messages

To view EMS event messages for an Integrity NonStop server, use one of these tools:

OSM Event Viewer

•

EMSDIST

•

ViewPoint

•

Web ViewPoint

•

Monitoring EMS Event Messages

OSM Event Viewer

The OSM Event Viewer is a browser-based event viewer. The OSM Event Viewer allows you to retrieve and view events from any EMS formatted log files ($0, $ZLOG, or an alternate collector) for rapid assessment of operating system problems.

To access the OSM Event Viewer, refer to Launching OSM Applications on pa ge 1-11. For details on how to use the OSM Event Viewer, refer to the online help.

EMSDIST

The EMSDIST program is the object program for a printing, forwarding, or consumer distributor, any of which you can start with a TACL RUN command. This guide does not describe using EMSDIST. For more information, see the Guardian User’s Guide.

ViewPoint

ViewPoint displays event messages about current or past events occurring anywhere in the network on a set of block-mode events screens. The messages can be errors, failures, warnings, and requests for operator actions. The events screens allow operators to monitor significant occurrences or problems in the network as they occur. Critical events or events requiring immediate action are highlighted.

OSM Event Viewer

Web View Po i nt

Web ViewPoint, a browser-based product, accesses the Event Viewer, Object Manager, and Performance Monitor subsystems. Web ViewPoint monitors and displays EMS events; identifies and lists all supported subsystems; manages NonStop server subsystems and user applications in a secure, automated, and customizable way; monitors and gr aphs pe rfor mance attribu tes and tr ends; investi gates a nd displays most active system processes; and offers simple navigation and a point-and-click command interface.

When to Use This Section

This section provides basic information about the different types of processes for Integrity NonStop servers. It gives a brief example of monitoring each type of process and provides information about the commands available for recovery operations.

Types of Processes

Three types of processes are of major concern to a system operator of an Integrity NonStop NS-series server:

System processes

•

I/O processes (IOPs)

•

Generic processes

•

System Processes

A system process is a privileged process that is created during system load and exists continuously for a given configuration for as long as the processor remains operable. Examples of system processes include the memory manager, the monitor, and the I/O control processes.

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

Page 78

Processes: Monitoring and Recovery

I/O Processes (IOPs)

An I/O process (IOP) is a system process that manages communications between a processor and I/O devices. IOPs are often configured as fault-tolerant process pairs, and they typically control one or more I/O devices or communications lines. Each IOP is configured in a maximum of two processors, typically a primary processor and a backup processor.

An IOP provides an application program interface (API) that allows access to an I/O interface. A wide area network (WAN) communications line is an example of an I/O interface. IOPs configured using the SCF interface to the WAN subsystem manage the input and output functions for the ServerNet wide area network (SWAN) concentrator. Examples of IOPs include, but are not limited to, line-handler processes for Expand and other communications subsystems.

Generic Processes

Generic processes are configured by the SCF interface to the Kernel subsystem. They can be configured in one or more processors. Although sometimes called systemmanaged processes, generic processes can be either system processes or usercreated processes. Any process that can be started from a TACL prompt can be configured as a generic process. Generic processes can be configured to have persistence; that is, to automatically restart if stopped abnormally.

I/O Processes (IOPs)

Examples of generic processes:

The $ZZKRN Kernel subsystem manager process

•

Other generic processes controlled by $ZZKRN; for example:

•

The $ZZSTO storage subsystem manager process

The $ZZWAN wide area network (WAN) subsystem manager process

QIO processes

OSM server processes

The $ZZLAN ServerNet LAN Systems Access (SLSA) subsystem manager

process The $FCSMON fibre channel storage monitor

For more information, refer to the SCF Reference Manual for the Kernel Subsystem.

Processes: Monitoring and Recovery

Monitoring Processes

This subsection briefly provides examples of some of the tools available to monitor processes. For some processes, such as IOPs, monitoring is more fully discussed in other manuals. In general, use this method to monitor processes:

1. Develop a list of processes that are crucial to the operation of your system.

2. Determine how each of these processes is configured.

3. Use the appropriate tool to monitor the process.

Monitoring System Processes

Check that the system processes are up and running in the processors as you intended. At a TACL prompt:

> STATUS *

This example shows partial output produced by the TACL STATUS * command:

Monitoring IOPs

For a list of manuals that provide more information about monitoring I/O processes (IOPs), refer to the WAN Subsystem Configuration and Management Manual, the

SWAN Concentrator and WAN Subsystem Troubleshooting Guide, and the Expand Configuration and Management Manual.

Monitoring Generic Processes

Because generic processes are configured using the SCF interface to the Kernel subsystem, you specify the $ZZKRN Kernel subsystem manager process when monitoring a generic process. These SCF commands are available for monitoring $ZZKRN and other generic processes:

INFO Displays configuration information for the specified objects NAMES Displays a list of subordinate object types and names for the

specified objects

STATUS Displays current status in formati on about the specified obje ct s

Monitoring the Status of $ZZKRN

To monitor the status of the $ZZKRN Kernel subsystem manager process, at a TACL prompt:

> SCF STATUS SUBSYS $ZZKRN

This example shows the output produced by this command:

1 -> STATUS SUBSYS $ZZKRN NONSTOP KERNEL - Status SUBSYS \COMM.$ZZKRN Name State Processes

(conf/strd) \COMM.$ZZKRN STARTED ( 25/22 )

Monitoring the Status of All Generic Processes

To monitor the status of all generic processes controlled by $ZZKRN, at a TACL prompt:

> SCF STATUS PROCESS $ZZKRN.#*

In nearly all circumstances, items that are essential to system operations that must be running at all times restart automatically if they are stopped for any reason while the NonStop Kernel operating system is running.

Some OSM processes stop after executing a macro that runs during system load or during the reload of processor 0 or 1. Those processes include $ZOLHI.

Optionally, you can also configure other processes such as the Expand subsystem manager process, $ZEXP, and the Safeguard monitor process, $ZSMP, as generic processes.

Recovery Operations for Processes

For recovery operations on generic processes, use the SCF interface to the Kernel subsystem and specify the PROCESS object. These SCF commands are available for controlling generic processes:

ABORT Terminates operation of a generic process. This command is not

supported for the subsystem manager processes.

START Initiates the operation of a generic process.

Generic processes that are configured to be persistent usually do not require operator intervention for recovery. In most circumstances, persistent generic processes restart automatically.

Communications Subsystems

The software that provides users of Integrity NonStop systems with access to a set of communications services is called a co mmunications su bsystem . Because con nectivity is an important part of online transaction processing (OLTP), HP offers a variety of communications products that support a wide range of applications.

Communication between specific devices or networks is typically achieved using several communications products or subsystems. These products are related as component s in a layered structur e. To accomplish the required connection, higher-level components—for example, NonStop TCP/IP processes—use the services of lowerlevel components such as the ServerNet LAN Systems Access (SLSA) subsystem.

The same higher-level component can often use any of several lower-level components; thus, the Expand subsystem—which consists of multiple processes on a node—can use the NonStop TCP/IP subsystem, the X.25 Access Method (X.25 AM),

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

Communications Subsystems: Monitoring and Recovery

or other communication interface options to provide data transmissions over local area networks (LANs) or wide area networks (WANs), respectively. Similarly, multiple higher-level components can use the services of a single lower-level component.

Local Area Networks (LANs) and Wide Area

Networks (WANs)

Local Area Networks (LANs) and Wide Area Networks (WANs)

Two important communications interfaces for LANs and WANs on Integrity NonStop servers are the SLSA subsystem and the WAN subsystem.

The SLSA subsystem supports parallel LAN I/O operations, allowing Integrity NonStop NS-series servers to communicate across the ServerNet fabrics and access Ethernet devices through various LAN protocols. SLSA also communicates with the appropriate adapter type over the ServerNet fabrics. Adapters supported on Integrity NonStop systems include:

Gigabit Ethernet 4-port adapter (G4SA)

•

Fibre Channel ServerNet adapter (FCSA) (for the Storage subsystem)

•

I/O adapter module (IOAM) enclosures enable I/O operations to take place between Integrity NonStop servers and some Fibre Channel storage devices. See the Modular I/O Installation and Configuration Guide for more information.

Adapters supported on NonStop S-series servers that can be accessed through Expand over IP, include:

ATM 3 ServerNet adapter (ATM3SA)

•

Ethernet 4 ServerNet adapter (E4SA)

•

Fast Ethernet ServerNet adapter (FESA)

•

Gigabit Ethernet ServerNet adapter (GESA)

•

Gigabit Ethernet 4-Port ServerNet adapter (G4SA)

•

Multifunction I/O board (MFIOB) in the processor multifunction (PMF) customer-

•

replaceable unit (CRU) and I/O multifunction (IOMF) CRU

Token-Ring ServerNet adapter (TRSA)

•

For further information, refer to the Introduction to Networking for NonStop NS-Series Servers.

In addition to the adapters, the SLSA subsystem supports these objects:

Processes

•

Monitors

•

ServerNet addressable controllers (SACs)

•

Logical interfaces (LIFs)

•

Filters

•

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

Page 85

Communications Subsystems: Monitoring and Recovery

Physical interfaces (PIFs)

•

Processes that use the SLSA subsystem to send and receive data on a LAN attached to an Integrity NonStop server are called LAN service providers. Two service providers—the NonStop TCP/IP and NonStop TCP/IPv6 subsystems and the Port Access Method (PAM)—are currently supported. They provide access for these subsystems:

LAN Service Provider Subsystems Supported

Local Area Networks (LANs) and Wide Area

Networks (WANs)

NonSto p TCP/IP subsyste m, NonSto p TCP/IPv6 subsys tem

Port Access Method (PAM) Ethernet and token-ring LANs. The OSI/AS, OSI/TS,

The Expand subsystem, which provides Expand-overIP connections.

SNAX/XF, and SNAX/APN subsystems communicate with SLSA through the PAM subsystem.

Processes, user applications, and subsystems that use the SLSA subsystem and related LAN providers to connect to an FCSA or G4SA attached to an Integrity NonS top NS-series server are called LAN clients. For exam ple, the W A N subsystem is a client of the SLSA subsystem because the SLSA subsystem provides the WAN subsystem access to the ServerNet wide area network (SWAN) concentrator through the LAN.

The WAN subsystem is used to control access to the SWAN concentrator. Depending on your configuration, it can be used to configure and manage both WAN and LAN connectivity for these communication subsystem objects:

Monitoring Communications Subsystem s and Their

Objects

Monitoring Communications Subsystems and Their Objects

Monitoring and recovery operations for communications subsystems can be complex. An error in any of the components—service providers, clients, objects, adapters, processes, and so on—can generate multiple error messages from many interdependent subsystems and processes. Analyzing and solving an error that originates in an object controlled by a LAN or a WAN often requires that you methodically gather status information about the affected services and then eliminate objects that are working normally.

Detailed monitoring and recovery techniques for devices and processes related to communications subsystems are discussed in detail in the manuals for each subsystem. For more information, refer to Related Reading on page 6-13.

This guide provides some basic commands you can use to identify and resolve common problems. Your most powerful tool for monitoring and collecting information about subsystem objects is the SCF facility. You can use SCF commands to get information and status for subsystem objects by name, device type, or device subtype.

Subdevices are defined if a subsystem potentially operates on numerous, separately addressable objects, such as stations on a multipoint line; the line is a device, and the stations are subdevices.

For a list of subsystems with their device type numbers and device subtypes, see

Using SCF to Determine Your System Configuration on page 2-5.

Monitoring the SLSA Subsystem

This subsection describes how to obtain the status of adapters, SACs, LIFs, and PIFs. For more information on the SLSA subsystem, refer to the LAN Configuration and Management Manual.

Tracing a Communications Line

Use the SCF TRACE command to trace the operation of a communications line. The line continues normal operation while being traced, but it passes all its message traffic to a trace procedure. Tracing enables you to see the hi story of a commun i cations li ne, including its internal processing.

You can display trace files by using the commands available in the PTrace program. For information about PTrace, refer to the PTrace Reference Manual. For information about configuring a trace by using the SCF TRACE command, refer to the configuration and manag emen t manu al for the comm unication s subsystem you want to trace.

When to Use This Section

Use this section to learn about monitoring and performing recovery operations for the internal and external ServerNet fabrics, and to understand how and when an Integrity NonStop NS-series system can be connected to legacy NonStop S-series I/O enclosures.

Notes. Integrity NonStop NS16000 systems support connectivity to NonStop S-series I/O enclosures, Integrity NonStop NS14000 and NS1000 systems do not. For more information, see Differences Between Integrity NonSto p NS-Series Systems on page 2-2.

An Integrity NonSto p NS16000 system can be part of the same ServerNet cluster as NonStop S-series systems, an Integrity NonStop NS14000 system cannot be. For more information, see the ServerNet Cluster Supplement for Integrity NonStop NS-Series Servers.

Integrity NonStop NS1000 systems do not support ServerNet clusters.

All Integrity NonStop system I/O is performed through the ServerNet system area network (SAN). LSU logic boards connect the SAN to the replicated four-way microprocessors on Integrity NonStop systems (except for Integrity NonStop NS1000 systems, which have no LSUs; see System I/O ServerNet Connections on page 7-4).

ServerNet Communications Network

The ServerNet communications network is a high-speed network within an Integrity NonStop system that connects processors to each other and to peripheral controllers. This network offers the connectivity of a standard network, but it does not depend on shared resources such as interprocessor buses or I/O channels. Instead, the ServerNet communications network uses the ServerNet architecture, which is wormhole-routed, full-duplex, packet-switched, and point-to-point. This network offers low latency, low software overhead, high bandwidth, and parallel operation.

In the ServerNet architecture, each processor maintains two independent paths to other processors, I/O devices, and ServerNet adapters. These dual paths can be used

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

simultaneously to improve performance, and to ensure that no single failure disrupts communications among the remaining system components.

A ServerNet adapter provides the interface between a ServerNet fabric and the Fibre Channel and Ethernet links. A ServerNet adapter contains a ServerNet bus interface (SBI) and one or more ServerNet addressable controllers (SACs).

Integrity NonStop NS16000 ServerNet Connectivity

An Integrity NonStop NS16000 system uses the ServerNet fabric for interconnections between the LSUs, p-switches, and IOAMs, enabling an Integrity NonStop system to be connected to legacy NonStop S-series enclosures. Figure 7-1 shows a logical representation of a complete system with the X and Y ServerNet fabrics.

System I/O ServerNet Connections

Integrity NonStop NS1000 ServerNet Connectivity

ServerNet connections between I/O devices and processors depend on whether the Integrity NonStop NS1000 system has an IOAM enclosure or VIO enclosures. For more information on Integrity NonStop NS1000 systems, see the NonStop NS1000

Planning Guide, NonStop NS1000 Hardware Installation Manual, or the Versatile I/O (VIO) Manual.

System I/O ServerNet Connections

For Integrity NonStop NS16000 systems, ServerNet connections to the system I/O devices (storage disk and tape drive as well as Ethernet communication to networks) radiate out from the p-switches for both the X and Y ServerNet fabrics.

ServerNet cables connected to the p-switch PICs in slots 10 through 13 come from the LSUs and processors. Cables connected to the PICs in slots 4 though 9 connect to one or more IOAM enclosures or to NonStop S-series I/O enclosures equipped with IOMF2 CRUs. Figure 7-3 shows the connections to the PICs in a fully populated p-switch.

For Integrity NonStop NS14000 systems, see Integrity NonStop NS14000 ServerNet

Connectivity on page 7-3. Like NS14000 systems, Integrity NonStop NS1000 systems

use 4PSEs to provide ServerNet connections between I/O devices and processors. However, there are no LSUs; the 4PSEs connect directly to the Blade Elements. For more information, see the NonStop NS1000 Hardware Installation Manual.
