Preface

This manual describes how to use VAX 4000 Model 300 timesharing and

VAXserver 4000 Model 300 server systems. The hardware and software for each of these systems differs slightly, according to the function of the system. The VAX 4000 is a multiuser system that uses the VMS operating system. The VAXserver 4000 system is a single-user system that uses VMS or VAXELN operating systems. Both systems can function as an end- or full-function node on an Ethernet network.

The manual is structured as follows:

• Chapter 1 provides an overview of the systems.

• Chapter 2 describes how to use each system.

• Chapter 3 describes how to use options installed in the systems.

• Appendix A lists related documentation.

• Appendix B describes how to set and examine DSSI device parameters from console mode.

• Appendix C describes procedures for creating backup files.

• Appendix D describes how to use VMSTAILOR to remove unwanted

VMS files from the system disk.

• A glossary explains key terms.

NOTE:

VAXserver systems are designed to offer maximum performance for applications that do not require timesharing. Some of the devices referred to in this manual are designed for multiuser systems and may not be suitable for server systems. Contact your Digital service representative if you have any questions about whether use of a specific device is appropriate for your server system.

The SCP has two indicators: the Over Temperature Warning light and the

DC OK indicator. The red Over Temperature Warning indicator flashes to indicate that the system’s internal temperature is approaching a level that may cause system components to overheat. In addition to the flashing Over

Temperature Warning light, an audible alarm also provides warning of a possible over temperature condition. If the components continue to heat, the system will automatically shut down to prevent components from being damaged. Chapter 2 provides instruction for turning on the system after a preventive shutdown due to overheat conditions.

The green DC OK indicator shows that the power supply voltages are within the correct operating range. If the DC OK indicator is not lit when the system power is on, refer to the VAX 4000 Troubleshooting and Diagnostics manual included in the Customer Hardware Information Kit.

Below the indicators are the Halt and Restart buttons. The Halt button is a two-position button. When you press the button, the system halts. A red indicator on the Halt button lights when the button is set to the in position.

Before you can enter console commands, press the Halt button again to

VAX 4000 Model 300 Operation

return it to the out position. When the Halt button is returned to the out position, the console mode prompt >>> is displayed on the console terminal screen. Now you can enter console commands. If you inadvertently press the Halt button, type ‘‘c

Return

’’ to continue. Chapter 2 describes halting the system in more detail.

CAUTION:

Pressing the Halt button halts the system regardless of the setting of the Break Enable/Disable switch on the console module.

Below the Halt button is the Restart button. The Restart button has a green indicator. When you press the Restart button, the system returns to a power-up condition and self-tests are run. If you have specified a device as the boot device and if the Break/Enable Disable switch is set to disable, the system will reboot system software. Further instructions on restarting your system are in Chapter 2.

NOTE:

The Halt and Restart buttons can be disabled to prevent accidental activation. Contact your Digital service representative if you want to disable the controls on the SCP.

The first four slots are reserved for memory modules. The fifth slot is reserved for the central processing unit (CPU). A console module with system controls and connectors covers these first five slots. Slots 6 through

12 are available for Q-bus option modules.

The number and type of modules installed in your system depend on your configuration. Each Q-bus slot, even an empty one, is protected by a module cover. Together the covers form a shield with a three-fold purpose:

• To protect external devices from electrical interference generated by the system

• To protect the system from electrical interference generated by external devices

1–10

VAX 4000 Model 300 Operation

• To maintain air flow integrity

CAUTION:

Do not operate the system without Digital-supplied module covers.

The covers are required to protect the equipment and to meet international regulatory standards. Do not substitute other module covers as they may not meet the required specifications.

Operating the system without the module covers has the following consequences:

• The system may overheat due to improper air circulation.

• The system will not comply with FCC and VDE requirements for electrostatic shielding and may produce electrical interference that affects other equipment.

• The system is susceptible to electrical interference or damage from external sources.

The design of the module covers varies, depending on the type of module installed in the slot. Modules requiring external cable connections, such as communications controllers, have recessed covers that are riveted directly to the module.

The recessed module covers allow space for connecting cables. Modules requiring no external cable connections, such as mass storage controllers, are covered by flush covers.

Empty slots are also covered by flush covers which may be single or double width. All covers, except those covering empty slots, have a label identifying the module installed in the slot.

Cables connecting your system to peripheral devices (such as terminals, modems, and printers) are attached to communications controllers. Each cable can contain multiple lines. The cables run under the BA440 enclosure and out the back or side of the enclosure, where the cables are split into individual lines. Chapter 3 describes these connections in more detail.

1.1.1.3 Console Module

Your system can have up to four memory modules. The memory modules occupy the first four slots of the card cage and are followed by the CPU. The memory and CPU modules are behind the console module that covers the first five slots. The console module, shown in Section 1.1.1.3, has several system controls and connectors.

The console module has the following components:

Power-Up Mode switch — This three-position rotary switch determines how the system responds at power-up:

Language Inquiry Mode (in the top position, indicated by a profile of a face) causes the system to display a language selection menu at power-up if your console terminal supports multiple languages. Also, if a default boot device has not been selected, this mode causes the system to issue a list of bootable devices and prompts you to select a device from the list. Once a device is selected, the system autoboots from that device each time you turn it on.

1–12

VAX 4000 Model 300 Operation

Run Mode (in the middle position, indicated by an arrow) is the normal operating setting.

Loop Back Test Mode (in the bottom position, indicated by a T in a circle) causes the system to run loopback tests on the console serial line at power-up. This setting requires special loopback connectors and is for Digital Customer

Services use only.

Baud Rate Select switch — The Baud Rate Select switch is used to set the system’s baud rate to match that of the console terminal. The factory setting is position 5 (9600).

Modified modular jack (MMJ) — This console terminal connector provides the connection for the console terminal.

The light-emitting diode (LED) display shows the testing sequence during power-up.

Break Enable/Disable switch — When the switch is down

(position 0), breaks are disabled. When the switch is up (position

1), breaks are enabled.

When breaks are enabled, pressing

Break on the console terminal halts the processor and transfers control to the console program. Using the console command

SET

CONTROLP

, you can specify the control character,

Ctrl/P

, rather than

Break to initiate a break signal.

The Break Enable/Disable switch also controls what happens at power-up.

When breaks are disabled (down, position 0), the system attempts to automatically boot software at power-up.

When breaks are enabled (up, position 1), the system enters console mode (indicated by the >>>prompt) at power-up.

Using the console command,

SET HALT REBOOT or

SET HALT

RESTART_REBOOT

, you can set your system to automatically boot software after the system is halted due to pressing

Break

.

Bus node ID plugs — VAX 4000 systems have two separate

Digital Storage System Interconnect (DSSI) busses. Two DSSI bus node ID plugs, one for the internal DSSI bus, Bus 0, and one for the external bus, Bus 1, identify the bus node of the

System Overview

1–13

CPU. These plugs are configured at the factory. For single-host systems, Bus 0 is identified as bus node 6, bus 1 is identified as bus node 7; for dual-host systems, both busses on the first host are identified as bus node 7, and both busses on the second host are identified as bus node 6.

DSSI connectors (DSSI Bus 1) — Two Digital Storage System

Interconnect (DSSI) connectors, labeled X and Y, on the console module allow you to expand your system by connecting additional mass storage devices to the second DSSI bus.

Ethernet connectors — The console module has two Ethernet connectors: a BNC-type connector for ThinWire Ethernet, and a 15-pin connector for a standard Ethernet transceiver cable.

The Ethernet connector switch allows you to set the type of connection. To use the standard transceiver cable connection, set the switch to the up position. To use the ThinWire cable connection, set the switch to the down position. A green indicator light (LED) for each connector indicates which connection is active.

1.1.1.4 DSSI Connector (DSSI Bus 0)

To the left of the card cage is the DSSI connector for DSSI Bus 0. Bus 0 provides the DSSI bus for DSSI devices installed in the system enclosure.

The connector allows you to expand your system by connecting additional mass storage devices to the bus. You can also share mass storage devices with a second system by forming a dual-host configuration. Figure 1–9 shows the location of the DSSI connector for DSSI Bus 0.

1.1.1.5 Power Supply Controls and Indicators

To the right of the card cage is the power supply. The power supply provides power to the mass storage devices, the modules installed in the card cage, and the fans.

To prevent damage due to overheating, the power supply monitors the internal temperature and the speed of the fans. If the power supply detects overheating or a fan failure, the power supply will shut down the system.

The controls and indicator lights function as follows:

Power switch — The power switch is used to turn system power on and off. The off position is indicated by a 0; the on position is indicated by a 1.

The power switch also functions as the system circuit breaker.

In the event of a power surge, the breaker will trip, causing the power switch to return to the off position (0). Turning the system on resets the circuit breaker. If the circuit breaker trips, wait one minute before turning on the system back on.

AC Present Indicator — The orange AC Present indicator lights when the power switch is set to on and voltage is present at the

VAX 4000 Model 300 Operation

input of the power supply. If the AC Present indicator does not light when the power switch is set to on, refer to your VAX 4000

Troubleshooting and Diagnostics manual.

DC OK — When the green DC OK indicator is lit, the power supply voltages are within the correct operating range. If the

DC OK indicator does not light when the power switch is set to on, refer to your VAX 4000 Troubleshooting and Diagnostics manual.

Fan Failure indicator — The amber Fan Failure indicator lights if either of the two cooling fans stop working. The power supply will automatically shut down the system as a precautionary measure when a fan failure is detected. Call your Digital service representative if a fan failure occurs.

Over Temperature Condition indicator — The amber Over

Temperature Condition indicator lights if the enclosure has shut down due to an over temperature condition. Section 2.9 provides instructions on recovering from an over temperature condition.

Power bus connectors — Three power bus connectors allow you to configure a power bus for systems expanded with the R400X or B400X expander. The power bus allows you to turn power on and off for one or more expanders through the power supply designated as the main power supply: this way, one power switch can control power for an entire expanded system. Figure 1–11 illustrates a possible power bus configuration for an expanded system.

NOTE:

Dual-host systems should not be configured with a power bus. Inadvertently shutting off a host system defeats the added reliability of a dual-host system.

The main out (MO) connector sends the power control bus signal to the expander.

One end of a power bus cable is connected here, the other end is connected to the secondary in (SI) connector of an expander power supply.

The secondary in (SI) connector receives the power bus control signal from the main power supply. In a power bus with more than one expander, the power control bus

System Overview

1–17

signal is passed along, using the secondary in and out connectors as shown in Figure 1–11.

The secondary out (SO) connector sends the signal down the power bus for configurations of more than one expander.

Figure 1–11: Sample Power Bus Configuration

1.1.1.6 Fans

Two fans located under the card cage draw air in through the top of the enclosure, down through the card cage, and out the bottom. The speed of the fans varies, depending on the surrounding room temperature. To reduce the load on the fans, keep the system away from heat sources. Figure 1–12 shows the air flow through the system enclosure.

NOTE:

The power supply monitors the fans. If either fan stops working, the Fan Failure indicator on the power supply lights, and the system automatically shuts down as a precautionary measure. Call your Digital service representative if a fan fails.

1–18

VAX 4000 Model 300 Operation

NOTE:

The fan speed control can be set so that the fans will run at their maximum speed. This setting is recommended if you want potentially higher system module reliability, and do not object to the increased fan noise.

Contact your Digital service representative to override the fan speed control.

1.2 Functional Description of Base System

Each VAX 4000 system includes base system components common to all systems. Your system may have optional components as well. Your system was configured at the factory, based on your order.

The following sections describe base system components and options, in turn.

1.2.1 Base System Components

Base system components include the following:

• Central processing unit (CPU)

• Console serial line unit (SLU)

• Main memory

System Overview

1–19

• Network controller

• Embedded DSSI host adapters

1.2.1.1 Central Processing Unit (CPU)

The central processing unit (CPU) controls the execution of all instructions and processes. The CPU circuits contain the logic, arithmetic, and control functions used by the system.

1.2.1.2 Console Serial Line Unit (SLU)

Each system has a serial line unit connecting the console terminal to the system. The SLU connector (a modified modular jack) is located on the console module. The console serial line provides a means of communicating with the CPU.

1.2.1.3 Main Memory

Main memory provides the electrical storage area for data and instructions used by the CPU. When you start your system, the operating system is loaded into main memory. Application programs must also be loaded into memory.

When the system cannot load everything into memory at once, it reads in units of data called pages (512 bytes of data) from disk. A large main memory increases the efficiency of processing, since fewer pages must be copied to and from the disk. Each configuration comes with a standard memory option. There is room for up to four memory modules. By adding more main memory, you can increase efficiency.

The contents of memory are volatile.

This means they are lost when you turn off power to the system.

Use mass storage devices, such as integrated storage assemblies and tape cartridges, to store software and data permanently.

1.2.1.4 Network Controller

Network communications controllers allow you to connect to an Ethernet network. With a network connection and appropriate DECnet software, you can use network services, such as mail; access data stored on other systems; perform operations, such as editing and printing on remote systems; and share resources, such as laser printers. Your system comes with an onboard

Ethernet controller that is part of the CPU. The system can connect to an Ethernet network through either standard Ethernet cable or ThinWire

Ethernet cable. Connectors for both types of cables are on the console module.

1–20

VAX 4000 Model 300 Operation

1.2.1.5 Embedded DSSI Host Adapters

Your system has two Digital Storage Systems Interconnect (DSSI) adapters built into the CPU. The DSSI adapters provide a path to two separate DSSI busses (Bus 0 and Bus 1) through which the CPU can communicate with

DSSI devices. Each DSSI adapter can support seven DSSI devices.

The DSSI host adapters also allow you to link one of the DSSI busses to a second host to form a dual-host configuration. When a DSSI bus is extended to a second system, both systems can share up to six DSSI devices. Refer to

Section 1.3 for further discussion of DSSI VAXcluster or dual-host systems.

1.2.2 Optional Components

System options can include multiples of components that are part of the base system (for example, additional memory modules or ISEs) and the following kinds of options:

• Mass storage devices and controllers

• Mass storage subsystems

• Mass storage expanders

• Communications controllers and adapters

• Real-time controllers

• Printer interfaces

1.2.2.1 Mass Storage Devices and Controllers

Mass storage devices record data on magnetic media. The data recorded is not lost when you turn off the system, but can be altered or erased if you record over the data. Use mass storage devices to store data and software permanently. When the data or software is needed, the CPU transfers it from the mass storage device into main memory. The two primary types of mass storage devices are the RF-series ISEs and devices with removable media, such as tape cartridges and compact disks.

Integrated Storage Elements

Up to four RF-series ISEs can be installed in your system. An ISE is an intelligent storage device that contains its own controller and server.

Special mounting hardware allows the device to plug directly into the

BA400-series backplane.

Devices with Removable Media

Devices with removable media, such as tape cartridges, are used as both input and output devices. In addition, compact optical disks are used as

System Overview

1–21

input devices when you install software or copy data to your system. You use tape cartridges and tapes as output devices when you copy software or data from your system. You can copy individual files or programs, or you can copy (back up) the contents of an entire fixed disk. Tapes are commonly used to archive data.

Mass Storage Controllers and Adapters

All mass storage devices require a controller, a device that controls activity between the CPU and the mass storage devices. While the controller for a

DSSI device is built into the storage device, other storage options require a controller module located in your system’s card cage. The controller for the

TK70 tape drive is the TQK70; the KDA50 is a controller for RA-series disk drives. Each KDA50 controller supports up to four RA-series disk drives.

The KZQSA adapter allows the CPU to communicate with the TLZ04 tape drive or RRD40-series digital compact disk drive. Each KZQSA adapter can support up to two drives.

The CPU communicates with DSSI devices through a Digital Storage

Systems Interconnect (DSSI) adapter, which is built into the CPU. Your

VAX 4000 system has two DSSI adapters and, hence, two separate DSSI busses. Each DSSI bus is capable of supporting seven DSSI devices. A third and fourth DSSI bus can be added to your system by using up to two

KFQSA DSSI storage adapter modules. Each KFQSA storage adapter can support up to seven DSSI devices.

NOTE:

As of this printing, the KFQSA storage adapter does not yet support the TF85 tape drive.

1.2.2.2 Mass Storage Subsystems

Several optional mass storage subsystems are available for VAX 4000 systems. Such subsystems include RRD42 compact disc subsystem, the

RV20 Optical Disk Subsystem, TSZ07, TS05, and TU81 tape drives, and the

SA600 Storage Array (with up to eight RA90 disk drives). If your system includes an optional mass storage subsystem, refer to the user’s guide or owner’s manual for that subsystem for instructions on how to operate the device.

1.2.2.3 Mass Storage Expanders

You can expand the mass storage and Q-bus capacity of your VAX 4000 system by using the following expanders:

• The R400X mass storage expander provides space for up to seven additional RF-series ISEs or up to six RF-series ISEs and a tape drive

(TF85 or TLZ04). Using R400X expanders, you can fill both DSSI busses for a total of 14 DSSI devices.

1–22

VAX 4000 Model 300 Operation

• The R215F expander provides space for up to three RF-series ISEs.

• The B400X expander provides 11 additional Q-bus slots for a system total of 18 Q-bus slots.

The B400X also has space for up to four additional RF-series ISEs or up to three ISEs and a tape drive (TF85,

TK70, or TLZ04).

• The B213F expander also provides 11 additional Q-bus slots and provides space for up to four RF-series ISEs or up to three ISEs and a TK70 tape drive. Contact your Digital representative for more information on these and other expander products.

1.2.2.4 Communications Controllers

Besides the console serial line, most systems have additional communications controllers for connecting additional terminals, and for communicating with other systems over telephone or network lines. Communications controllers provide standard interfaces between peripheral devices and the system.

Many communications controllers provide support for multiple data lines.

The following types of communications controllers are available:

• Asynchronous serial controllers

• Synchronous serial controllers

• DECservers

• Network controllers

Serial controllers transmit data one character at a time. A device at the transmitting end breaks bytes of data into bits. A device at the receiving end assembles incoming bits into bytes of data.

Asynchronous Serial Controllers

Asynchronous serial controllers provide low-speed connections between peripheral devices and the system. Asynchronous communication between the system and the peripheral depends on recognition of a pattern of start and stop bits, not on a time interval.

Asynchronous serial controllers may be divided into those without modem support and those with modem support.

You use serial controllers without modem support to connect additional terminals and printers to your system. For example, the CXA16 module provides connections for up to 16 serial lines with no modem support.

System Overview

1–23

NOTE:

Printers equipped with a microprocessor (intelligent printers) may require modem control signals to function correctly. Do not attach a printer requiring modem control signals to a controller with no modem support.

Check your printer documentation to determine the proper communications interface for your printer.

Communications controllers with modem support allow you to communicate over telephone lines. With a modem connected to your system, you can access other computers and you can dial into your system from a remote terminal or computer.

Computers transmit digital signals, while telephone lines (with the exception of digital leased lines) transmit analog signals.

When two computers communicate over telephone lines, a modem is required at both the transmitting and receiving ends of the line. At the transmitting end, the modem converts digital signals from the computer (or terminal) to analog signals prior to transmission. At the receiving end, another modem converts the analog signals back into digital signals the computer can process.

The degree of modem support depends on the number of modem control signals recognized by the device. Full modem support (according to Digital standards) requires recognition of eleven signals.

The CXY08 module supports up to eight serial lines with full modem support.

Synchronous Serial Controllers

Synchronous serial controllers provide high-speed connections between systems. Communication between synchronous devices depends on time intervals that are synchronized before transmission of data begins.

Synchronous devices can also have modem support.

DECservers

DECservers are terminal servers (a combination of hardware and software) that allow you to connect multiple terminals or printers to hosts in an

Ethernet Local Area Network (LAN).

Terminal servers perform the functions of traditional data terminal switches but multiplex the lines over the Ethernet. Using a DECserver offloads communications processing from the host system.

Network Controllers

Network communications controllers allow you to connect to an Ethernet

LAN or other network type. With a network connection and appropriate

DECnet software, you can use network services, such as mail; access data stored on other systems; perform operations, such as editing and printing on remote systems; and share resources, such as laser printers. The network

1–24

VAX 4000 Model 300 Operation

controller function for your system is implemented on the CPU module, but a second network controller, the DESQA Ethernet adapter module, can be added to your system.

1.2.2.5 Real-Time Controllers

Real-time controllers interface with devices that monitor or control particular processes, for example, laboratory equipment or manufacturing equipment connected to the system. Typically, real-time controllers are parallel devices, not serial devices.

1.2.2.6 Printer Interfaces

Some printers require specific interfaces to communicate with the system.

For example, the LG01, LG02, and LP29 and LP37 printers require the

LPV11–SA interface module.

1.2.2.7 Other Available Options

Your system arrives configured with the options you ordered. As your needs change, you can add more options. Your Digital sales representative can advise you on available options. VAX 4000 Model 300 Technical Information describes the options currently available for VAX 4000 systems. Digital provides installation for additional options that you order.

1.3 Dual-Host Capability (VMS Systems Only)

A dual-host system consists of two systems in a DSSI VAXcluster sharing their DSSI devices through a Digital Storage Systems Interconnect (DSSI) bus. Each system can have direct access to any of the devices in either system; this can include a shared common system disk.

The primary application for such a configuration is a DSSI VAXcluster system. The simplest dual-host configuration, for example, is to configure one system disk to be used as the system disk by both systems. The system disk physically resides in one enclosure, however, both systems have equal access to the system disk and to any other DSSI mass storage device in either enclosure.

A DSSI device, such as the RF72, has a built-in dual-host capability that allows it to connect to two DSSI host adapters. The DSSI storage adapter, embedded in the system’s CPU, allows you to extend a DSSI bus by physically connecting it to another system.

Using an external DSSI cable, any two DSSI-based systems can be connected to form a DSSI VAXcluster or dual-host configuration.

Figure 1–13 shows a dual-host configuration with two VAX 4000 systems.

System Overview

1–25

NOTE:

Dual-host capability for VAX 4000 systems is only supported under

VMS (Version 5.3–2 and later) when the two systems are configured into the same VAXcluster.

The benefits of a dual-host configuration are:

• VAXcluster features such as shared data across systems and satellite nodes.

• Higher system availability — If one of the DSSI-based systems is unavailable, for example, due to a system malfunction, the satellites booted through it are able to continue operating through the other system.

If one of the DSSI-based systems fails, all satellite nodes booted through that system lose connections to the system disk. Each satellite node knows, however, that the system disk is also available through a second path. The satellite nodes establish a new connection through the other system and continue operation.

To increase system availability, a second system disk may be added to each boot node. In the event of one system disk failure, the remaining system disk would continue to serve one DSSI-based system and the satellite nodes booted through it. As with any VAXcluster, however, a second system disk improves availability while increasing system management tasks.

Chapter 2

Operating the System

This chapter describes how to operate your VAX 4000 system once the system software has been installed or you have completed startup procedures for factory-installed VMS.

2.1 Before You Operate the System

This chapter assumes that your system has been properly installed.

Installation includes running the diagnostic software shipped with your system and installing the base operating system, or completing the first time startup procedures for factory-installed VMS. Refer to Appendix A of the VAX 4000 Model 300 Installation manual for instructions on starting up factory-installed VMS. To install other operating system options or layered products, see the instructions in your system software installation manual or layered product installation manual.

Some of the instructions may require you to open the front door of the system to change switch settings on the console module.

The remainder of this chapter assumes that system software has been installed and first time startup procedures for factory-installed VMS have been completed.

2.2 Switch Settings

Switch settings vary, depending on the operation being performed. The next two sections describe switch settings for normal and for special operations.

Set the switches according to your needs.

2.2.1 Normal Operation

Switch settings for normal operation are the following:

• The Break Enable/Disable switch on the console module is set to disable

(down, position 0). Digital recommends you run the system with breaks disabled to prevent the user from inadvertently halting the system by pressing

Break on the console terminal. Halting the system causes all activity to stop.

Operating the System

2–1

With breaks disabled, the system automatically boots system software when powered on.

NOTE:

You can use the console command SET CONTROLP to specify the control character,

Ctrl/P

, rather than

Break

, to initiate a break signal.

Using the console command, SET HALT REBOOT or SET HALT

RESTART_REBOOT, you can set your system to automatically boot software after the system is halted due to pressing

Break

.

• The Power-Up Mode switch on the console module is set to Run

(indicated by an arrow).

• The Baud Rate Select switch on the console module is set to 9600

(indicated by a switch setting of 5).

• The Write-Protect button for each RF-series ISE is set to out (not lit).

This setting allows system software to write to the storage element.

• The Run/Ready button for each RF-series ISE is set to in (glows green when the storage element is not being used). This setting makes the storage element available for use.

• The Halt button on the SCP is set to out (not lit).

• For expanded systems using power bus cables to link the R400X or

B400X expander, the power switches on all expander power supplies should remain on (set to 1) at all times. The system power supply sends the power bus signal needed to turn the expanders on or off.

2.2.2 Special Operation

Certain operations require that you change some of the normal operating settings.

• If you need the ability to halt the system from the console terminal, for example, when installing system software or performing certain types of backup, set the Break Enable/Disable switch to enable (up, position

1). This allows you to halt the system by pressing

Break on the console terminal.

NOTE:

You can use the console command SET CONTROLP to specify the control character,

Ctrl/P

, rather than

Break

, to initiate a break signal.

Using the console command, SET HALT REBOOT or SET HALT

RESTART_REBOOT, you can set your system to automatically boot software after the system is halted due to pressing

Break

.

2–2

VAX 4000 Model 300 Operation

• If you want data on a particular ISE to be write-protected, you must set the Write-Protect switch to in (glows).

NOTE:

ISEs containing system software and user accounts must remain write-enabled. ISEs containing applications or sensitive data may be write-protected.

• If you want to use the Language Selection Menu to select a new language for the console program, before you turn on your system, set the Power-Up Mode switch to Language Inquiry Mode. A human profile indicates the language inquiry mode. When you turn on your system, a Language Selection Menu appears, as shown in Figure 2–1.

Save the language you have selected by rotating the Power-Up Mode switch to Run Mode, indicated by an arrow.

NOTE:

If you do not select a language within 30 seconds, the system defaults to English (United States/Canada).

If the Power-Up Mode switch is set to Run Mode (indicated by an arrow), then the language selected is saved and is automatically used during subsequent reboots of the system.

Operating the System

2–3

NOTE:

If the Power-Up Mode switch is set to Language Inquiry Mode

(indicated by the human profile), the system will prompt for the language at each power-up.

In addition to the Language Selection Menu, the system may issue a list of bootable devices and prompt you to select a device from the list.

If this happens, refer to Section 2.4.1 for more information.

If your system has been powered off for more than 10 days, the battery unit that saves the system clock and the language selection may have run down. The Language Selection Menu will be automatically displayed when you power on your system, regardless of the Power-Up

Mode switch setting. Once the system is booted, reset the system clock as described in your system software manual.

2.3 Turning On the System

Once you have set the switches correctly, you are ready to turn on the system. Use the following procedure:

1.

Turn on the console terminal and wait for it to complete its self-tests.

2.

Turn on the system by setting the Power switch to 1.

NOTE:

For systems using the R400X or B400X expander linked by a power bus cable, the Power switch on the VAX 4000 provides the power control bus signal to the expander(s). Setting the Power switch to on (1) on the VAX 4000 will cause the expander(s) to power up as well. The

Power switch on the expander(s) should always remain in the on position

(1).

When you turn on the power, you should see the indications listed in Table

2–1.

Troubleshooting and Diagnostics.

Every time you turn on your system, it runs a series of self-tests on the

CPU and memory. Your console terminal first displays a line of information identifying the CPU, the version of the firmware, and the version of VMB— the primary bootstrap program. In the sample screens provided in this chapter, the CPU is identified as a KA670–A, and the versions of the firmware and primary bootstrap are indicated as n.n. Your system will display actual version numbers.

The console terminal then displays a countdown as the system tests itself. When the self-tests are successful, the system either autoboots system software or goes into console mode, as described in Sections 2.4.1 and 2.4.2.

If your system detects an error during its self-tests, it displays an error summary consisting of several lines of hexadecimal numbers. A Digital service representative can use the error summary to diagnose the system.

Depending on the type of error, one or more error summaries may display on the console terminal. A sample error summary is shown in Figure 2–2.

2.4 Booting the System

VAX 4000 systems boot in one of two ways. You can configure the system to autoboot on power-up or you can manually boot the system from console mode. The Break Enable/Disable switch setting determines how the system boots.

2.4.1 Autobooting the System

When the Break Enable/Disable switch is set to disable (the normal operating setting), the system runs self-tests and, on completion, attempts to load system software. Additionally, if the Break Enable/Disable switch is set to enable, and the halt action

REBOOT or

RESTART_REBOOT has been defined using the SET HALT command, the system will automatically attempt to load system software.

Depending on whether or not a boot device has been selected, the system loads system software or prompts you to select a boot device.

Loading System Software (With Boot Device Selected)

When a boot device has been selected, the system identifies the boot device and the number ‘‘2’’ displays on the screen. As the system begins booting, the countdown continues from 1 to 0.

Changing the Boot Device

Once a boot device is identified, the system autoboots from that device each time you turn it on, until you do one of the following:

• Change the setting of the Break Enable/Disable switch to enable (up, position 1). If you do so, the system will not autoboot but will enter console mode after completing self-tests (assuming you have not defined a halt action of

REBOOT or

RESTART_REBOOT using the

SET HALT console command).

Refer to Section 2.4.2 for instructions on booting from console mode.

• Change the boot device by using the SET BOOT command.

2–8

VAX 4000 Model 300 Operation

Using the SET BOOT Command

To direct the system to boot automatically from a specific device or to change the setting of the default boot device, put the system into console mode and at the >>> prompt, enter ‘‘SET BOOT device-name’’. For example,

>>>

SET BOOT EZA0

sets the system default boot device to be the Ethernet controller.

Once you have selected a boot device, the system autoboots from that device each time you turn it on.

Using ‘‘SET BOOT device-name,device-name,device-name’’, you can also specify a string of default boot devices (up to 32 characters, with devices separated by commas and no spaces) for which the system will check for bootable software. The system checks the devices in the order specified and boots from the first one that contains bootable software. For example,

>>>

SET BOOT DUA0,DIA0,MIA0,EZA0

directs the system to use DUA0, DIA0, MIA0, and EZA0 as the default boot devices. When the system autoboots, or if the BOOT command is used without specifying a device, the system will boot from the first default boot device that contains bootable software.

NOTE:

If included in a string of boot devices, the Ethernet device, EZA0, should only be placed as the last device of the string.

The system will continuously attempt to boot from EZA0.

To determine the name of the device from which to boot the system, refer to Table 2–2, or enter the SHOW DEVICE command at the console prompt

>>>. Figure 2–6 shows a sample list of devices. The system displays the logical device name, preceded by a dash (–), for each device.

NOTE:

Selecting a default boot device other than the Ethernet device, EZA0, is not appropriate for diskless and tapeless systems which must boot software over the network.

Loading System Software

To load system software from console mode, enter the BOOT command,

‘‘BOOT device name’’. For example,

>>>

BOOT MUA0

tells the system to boot software from a cartridge in the TK70 tape drive.

If you enter the BOOT command without specifying a device, the system will attempt to boot from the default boot device, or string of devices defined by the SET BOOT command.

Using ‘‘BOOT device-name,device-name,device-name’’, you can also specify a string of boot devices (up to 32 characters, with devices separated by commas and no spaces) for which the system will attempt to boot software.

The system checks the devices in the order specified and boots from the first one that contains bootable software. For example,

>>>

BOOT DUA0,DIA0,MUA0,EZA0

directs the system to boot from the first device in the list that contains bootable software.

NOTE:

If included in a string of boot devices, the Ethernet device, EZA0, should only be placed as the last device of the string.

The system will continuously attempt to boot from EZA0.

Operating the System

2–11

NOTE:

To determine the name of the device from which to boot the system, refer to Table 2–2.

Software manuals may instruct you to power on with break enabled and to use the BOOT command.

2.5 Using the System

Once the system software is loaded, the first display for the system software appears on the console terminal after a few seconds.

That display is described in the system software documentation.

You are now ready to use the system. Refer to the system software manuals and application manuals for more specific instructions on using the system.

Your system software manuals cover the following:

• Installing software on your system

• Running software to perform tasks

• Making and restoring backup copies of system software or data files

• Accessing devices and utilities in your system

2.6 Halting the System

Halting the system interrupts all processes and returns control to the console program.

You may need to halt the system during software installation. Or, you may want to boot the system from another device, for example, a tape cartridge containing MicroVAX Diagnostic Monitor (MDM) software.

CAUTION:

Halting your system without following the shutdown procedure described in your system software manuals may result in loss of data.

You can halt the system in two ways:

• You can press the Halt button twice — in to halt the system, and out to enter console mode.

• If the Break Enable/Disable switch on the console module is set to enable (indicated by 1) you can press the

Break key on the console terminal. If the Break Enable/Disable switch is not set to enable and you wish to halt the system by pressing

Break

, change the setting of the

Break Enable/Disable switch from disable to enable.

2–12

VAX 4000 Model 300 Operation

NOTE:

You can use the console command SET CONTROLP to specify the control character,

Ctrl/P

, rather than

Break

, to initiate a break signal.

CAUTION:

If you shut off your console terminal while breaks are enabled, the system interprets the action as a break, and the system halts.

If you are using a system that is part of a VAXcluster, do not halt, restart, or turn off the system without consulting the cluster manager. Performing any of these activities will interrupt the processes of the entire cluster.

When the console mode prompt (>>>) is displayed on your screen, the system is halted.

If you inadvertently halt the system, type ‘‘c

Return

’’ at the console prompt.

The processes interrupted by the halt will continue.

2.7 Restarting the System

NOTE:

Restarting the system aborts all current and pending operations. To prevent loss of data, warn all users to log off prior to restarting the system.

Follow the shutdown procedure described in your system software manuals before restarting the system.

Restarting returns the system to a power-up condition. All current and pending operations are aborted and the usual power-up tests are run.

You restart the system by pressing the Restart button on the system control panel.

NOTE:

The Halt button must be out (not lit) to effect a restart operation.

2.8 Turning Off the System

CAUTION:

Turning off your system without following the shutdown procedure described in your system software manuals may result in loss of data.

Once you have completed the recommended procedure, you can turn off your system by setting the Power switch to 0.

NOTE:

For systems expanded with the R400X or B400X expander and linked by a power bus cable, you need only turn off the system unit: The expander(s) will power down when you set the system Power switch to off

(0). Note that the orange ac indicator on the expander power supply should remain lit even though the system Power switch set to off (0).

Operating the System

2–13

2.9 Recovering from an Over Temperature

Condition

If your system’s internal temperature approaches a level that may cause components to overheat, an audible alarm will sound and the Over

Temperature Warning indicator on the SCP will flash. If the temperature continues to increase, the system will automatically shut down.

If the overheat warnings are activated, the alarm sounds and the Over

Temperature Warning indicator flashes.

When the system shuts down due to overheating, the Over Temperature

Condition indicator on the power supply remains lit. To recover from a shutdown, set the Power switch to off (0) and wait five minutes before turning on the system.

To prevent an over temperature condition, use the following precautions:

• Make sure your system is away from heat sources.

• Check that the system’s air vents are not blocked.

• Check that the room temperature is within acceptable limits as specified in your VAX 4000 Site Preparation manual.

Chapter 3

Operating the System Options

This chapter describes how to use options that may already be part of your system, or that you can add to your system. The following types of options are covered:

• Mass storage devices and controllers

• Communications controllers

• Real-time controllers

• Printers

NOTE:

Some of these options may not be appropriate for VAXserver 4000 systems. Contact your Digital representative if you have any questions about whether a specific option is appropriate for your system.

3.1 Mass Storage Options

The following mass storage options may be included with VAX 4000 systems:

• RF-series Integrated Storage Element (ISE)

• TF85, TK70, or TLZ04 tape drive

NOTE:

In addition, the RV20 Optical Disk Subsystem, RRD4x Digital Disc

Subsystem, TSZ07, TSV05, and TU81 tape drives can be attached to the

VAX 4000 system. If your system contains one of these options, refer to the user’s guide or owner’s manual for instructions on how to operate the device.

This chapter describes how to use the controls for the RF-series ISEs and the TF85, TK70, and TLZ04 tape drives. In the case of the tape drives, it also describes how to insert and remove the tape cartridge. To use any mass storage device, you must properly identify the device to the operating system and use appropriate operating system commands. Refer to your system software documentation for details.

Operating the System Options

3–1

3.1.1 RF-Series Integrated Storage Elements

Your system may have up to four RF-series ISEs or up to three RF-series

ISEs and a tape drive.

When your system has multiple ISEs, Digital recommends that you separate them according to function. For example, if your system has two ISEs, you may want to use them as follows:

• ISE 0 contains the operating system and applications installed on the system.

• ISE 1 contains work areas for each user with an account on the system.

The storage capacities and other specifications for RF-series ISEs are listed in VAX 4000 Model 300 Technical Information.

NOTE:

Refer to Appendix B for information on setting or examining parameters for DSSI devices.

3.1.1.1 RF-Series Controls and Indicators

Each RF-series ISE has controls and indicators on its front panel. To access the ISE controls you need only open the upper door (top key position).

Figure 3–1 shows the front panel of an RF-series ISE.

NOTE:

If your system has less than the maximum number of ISEs: three if you have a tape drive, or four without the tape drive, a blank ISE front panel with no controls or indicators is used to cover the empty ISE cavities.

The front panels are required to meet international regulatory standards.

3.1.1.2 Changing the Bus Node ID Plugs

Spare bus node ID plugs are supplied with your system. Use the spare plugs to renumber your ISEs if you reconfigure your system with an expander, or if you create a dual-host configuration.

The bus node ID plugs have prongs on the back that indicate the bus node number (and by default, the unit number) of the ISE. To remove a bus node

ID plug, grasp it firmly and pull straight out. To insert a bus node ID plug, align the two center prongs with the two center slots and press the plug into the slots. See Figure 3–2.

Figure 3–2: Inserting Bus Node ID Plugs

Bus Node

ID Plug

MLO-004045

Use the rules below for renumbering your storage elements:

• For each DSSI bus, do not duplicate bus node numbers for your storage elements. You can only have one storage device identified as bus node

0, one storage device as 1, and so on.

• By convention, the ISEs are numbered in increasing order from right to left.

NOTE:

If you change the bus node ID plugs while the system is operating, you must turn off the system and then turn it back on for the new plug positions to take effect.

3.1.2 TF85 Tape Drive

The TF85 tape drive is located behind the upper door of the system. To use the drive, move the key to the top position and open the door.

The TF85 tape drive holds one removable magnetic tape cartridge. The drive can read data written on either a CompacTape III, CompacTape II, or

CompacTape cartridge; but cannot write to a CompacTape II or CompacTape cartridge. You must use a CompacTape III cartridge to make copies or backups of software or data. You can identify the type of cartridge by the label on the cartridge. Table 3–2 shows cartridge compatibility with the

TF85 tape drive.

NOTE:

The TF85 can read cartridges recorded by TK-series tape drives.

TF85 Tape Drive Controls and Indicators

The tape drive has two primary controls: the cartridge insert/release handle

(subsequently referred to as the ‘‘handle’’) and the Unload button. You use the handle to insert or remove cartridges and lock them into position. Pull the handle open to insert or remove a tape cartridge. Push the handle closed to lock a tape cartridge into position and load the tape.

You use the Unload button to rewind and unload the tape. Rewinding and unloading can also be controlled by software. Refer to your system software manuals for appropriate commands.

A bus node ID plug on the drive’s front panel identifies the bus node number of the device to the system as well as the unit number by default.

NOTE:

Refer to Appendix B for information on setting or examining parameters for DSSI devices.

The drive also has four indicator lights that show the status of the drive.

3.1.2.1 Design of the Drive

The TF85 tape drive operates like a reel-to-reel tape deck. Inside the drive is a take-up reel with a leader attached. Inside the cartridge is a single reel containing the magnetic tape. When you insert the cartridge and push in the handle, the leader in the drive automatically couples with the leader in the cartridge, and the tape winds onto the take-up reel. The coupling and winding process is called loading. When the automatic loading process is complete, the tape is ready to use.

Once the cartridge is loaded, you cannot remove it without rewinding and uncoupling the leaders, a process called unloading. Even if you have not used the tape, you must unload it before you can remove the cartridge.

When you press the Unload button, the tape rewinds into the cartridge and the leaders uncouple.

3.1.2.2 Labeling a Tape Cartridge

When recording data on a cartridge, label its contents.

For your convenience, a slot for the label is provided on the front of the cartridge.

Write the identification on the label and insert the label in the slot on the front of the cartridge, as shown in Figure 3–4. The label is visible when the tape is in the drive.

NOTE:

Do not write on the tape cartridge or attach labels to the top, bottom, or sides of the cartridge.

3.1.2.3 Write-Protecting a Tape Cartridge

Write-protecting a tape cartridge prevents accidental erasure of information stored on the tape. You can write-protect a tape cartridge in two ways:

• Set the write-protect switch on the cartridge to the write-protect position.

• Write-protect the cartridge by using operating system commands described in your system software manuals.

Operating the System Options

3–9

Your system can read information on the tape regardless of the position of the write-protect switch or whether writing is software disabled. However, the system cannot write data to the tape when the write-protect switch is set to the write-protect position, or when writing is software disabled.

When you use a cartridge to install software, make sure the cartridge is write protected. Two icons on the switch indicate the write-protect status, as shown in Figure 3–5. An orange rectangle is visible when the switch is in the write-protect position. If you do not see an orange rectangle, slide the switch toward the label slot.

When you insert a write-protected cartridge into the drive, the orange writeprotect indicator lights. The system recognizes the tape as being writeprotected under any one of the following conditions:

• The write-protect switch on the cartridge is set to the write-protect position.

• An operating system command has write-protected the tape.

• A tape recorded on a TK-series tape drive is inserted into the drive.

Removing write-protection depends on how the tape was recorded and how it is write protected. You cannot write-enable a tape recorded on a TK50

/TK70 tape drive either by moving the write-protect switch on the cartridge or by using software commands. The TF85 tape drive always recognizes a tape recorded on a TK50/TK70 drive as write-protected. You can remove write-protection on tapes recorded on a TF85 tape drive as follows:

• If the cartridge is write protected only by the write-protect switch on the cartridge and not the operating system, moving the switch to the writeenabled position causes the write-protect indicator light to go out.

• If the cartridge is write protected only by a software command and not the write-protect switch, removing the operating system restriction causes the write-protect indicator to go out.

• If the cartridge is write protected by both the switch on the cartridge and a software command, you must change the switch setting and remove the operating system restriction.

Operating the System Options

3–11

When you use a CompacTape III cartridge to make a backup copy of files, make sure the orange write-protect indicator on the TF85 is off. If the indicator is not off, check for any of the write-protect conditions described above. Change the switch setting and/or operating system restriction as necessary. Do not begin your operation until the write-protect indicator goes off.

3.1.2.4 Tape Cartridge Handling and Storage Guidelines

• Do not touch the exposed surface of the tape.

• Do not drop the tape cartridge. The impact from a fall can damage the tape cartridge.

• Allow new tapes to stabilize at room temperature for 24 hours before using them.

• Place an identification label only in the label slot on the front of the tape cartridge.

• Store tape cartridges in a dust-free environment.

• Keep tape cartridges away from direct sunlight, heaters, and other sources of heat. Store tape cartridges in a stable temperature between

10° and 40°C (50° and 104°F).

• Store tape cartridges where the relative humidity is between 20 and 80 percent.

• Keep tape cartridges away from magnets and equipment that generate magnetic fields, such as motors, transformers, terminals, and audio equipment.

• Keep tape cartridges away from x-ray equipment.

3.1.2.5 Inserting a Tape Cartridge

Before you use the tape drive, make sure the system is turned on. During power-up, the TF85 drive runs self-tests that last a few seconds.

All four indicator lights come on momentarily, then the yellow (Tape in Use) indicator blinks during the self-tests. At the end of the tests, the yellow indicator goes off and the green (Operate Handle) indicator comes on, accompanied by a short beep. The green indicator and the beep indicate that you can move the cartridge release handle.

CAUTION:

Move the handle only when the green indicator light is on.

Moving the handle while the yellow indicator light is on could damage the drive. If all four indicators blink rapidly at any time, a fault condition exists.

Press the Unload button once. If the fault is cleared, the tape unloads. The

3–12

VAX 4000 Model 300 Operation

yellow indicator blinks during unloading, then the green indicator comes on. If the fault is not cleared, the four indicators continue to flash. Do not attempt to use the tape drive or to remove the tape cartridge. Call your

Digital service representative.

Use the following procedure to insert a tape cartridge (see Figure 3–6):

1.

Pull the handle open.

2.

Position the cartridge so the arrow on the cartridge faces left and points toward the drive. Insert the cartridge into the tape drive until you feel the cartridge lock into place.

3.

Push the handle closed.

The green indicator goes off and the yellow indicator blinks as the tape loads. When the yellow indicator glows steadily, the tape is ready to use.

NOTE:

If the green indicator blinks rapidly when you push the handle closed, the drive has detected a cartridge fault. Pull the handle open and remove the cartridge. Use another cartridge.

Refer to Appendix C for instructions on how to create backup files on a tape cartridge.

NOTE:

If a cartridge is new, the drive performs a calibration sequence that takes approximately 30 seconds when the drive receives the first command from the operating system. The yellow indicator blinks rapidly and irregularly during calibration.

3.1.4 TLZ04 Tape Drive

The TLZ04 tape drive is located behind the upper door of the system. To use the drive, move the key to the top position and open the door.

The TLZ04 tape drive is a backup device that uses digital data storage

(DDS) and digital audio tape (DAT) recording technologies. Digital audio tape, such as TLZ04 cassettes, takes advantage of the TLZ04 tape drive’s helical scan technology. This technology allows more data to be stored on tape by recording data diagonally.

DAT recording also minimizes

‘‘crosstalk,’’ providing you with higher data integrity.

Digital data storage uses a recording format that supports the use of digital audio tape for computer applications. The DDS/DAT format allows you to backup 1.2 gigabytes of data in approximately 2 hours with no operator intervention. In addition, this format has three levels of error correction, which ensures high data integrity.

3.1.4.1 Proper Handling of Cassette Tapes

Digital Equipment Corporation recommends that you use TLZ04 cassette tapes. To ensure optimal performance from your cassette tapes, observe the following guidelines when handling them.

• Avoid placing the cassette tapes near sources of electromagnetic interference, such as terminals, and video or X-ray equipment.

Emissions from such equipment can erase data on the tape.

• Keep cassette tapes out of direct sunlight and away from heaters and other sources of heat.

• Store cassette tapes (and cleaning cassette) where the room temperatures are between 5°C and 32°C (40°F and 90°F).

• Store cassette tapes in a dust-free environment where the relative humidity is 20% to 60%.

3.1.4.2 Setting the Write-Protect Tab on the Cassette Tape

If you wish to read or copy from a tape, set the write-protect tab on the cassette to write protect. This disables writing to tape, and ensures data integrity. Use a pen (not pencil) to set the write-protect tab (Figure 3–14) to the desired position.

Observe the following guidelines when setting the write-protect tab.

• If you are reading data (copying from tape), set the write-protect tab to write protected.

• If you are writing data, set the write-protect tab to write enabled.

• Write-protect tab position displays in front panel tape indicator.

3.1.4.5 Cleaning the Heads

Statistics show that over ninety percent of drive-related problems are associated with the media.

Therefore, Digital Equipment Corporation strongly recommends that you follow the instructions for handling cassette tapes and cleaning the heads of the drive.

This section shows you how to perform TLZ04 head cleaning. The heads are the components, in a drive, that magnetically read and write data to and from the media (in this case, a cassette tape).

NOTE:

Digital Equipment Corporation recommends that you perform the head cleaning procedure about every two weeks, or after every 25 hours of drive usage.

Under normal conditions, it should not be necessary to exceed this cleaning schedule. If a particular cassette causes problems, try changing to another cassette.

CAUTION:

Never attempt to clean the heads in a manner other than described herein. Doing so will void the product warranty.

To clean the heads, use the head cleaning cassette as follows:

1.

Observe that the drive indicator is lit solid green.

2.

Insert the head cleaning cassette (part number TLZ04–HA) into the drive as shown in Figure 3–16.

3.

With the head cleaning cassette inserted, the drive automatically cleans the head.

The drive ejects the head cleaning cassette after approximately 30 seconds.

4.

In the space provided on the card enclosed with the head cleaning cassette, place a check mark every time you use the head cleaning cassette.

Under normal conditions, the head cleaning cassette performs for approximately 25 cleanings. Additional cassettes are available from your Digital sales representative or DECdirect.

If the head cleaning cassette has been used more times than it was designed to be used, the drive will eject the cartridge in approximately

8 to 10 seconds. No cleaning action will occur.

CAUTION:

Do not exceed the recommended 25 uses of the cleaning cassette. After 25 uses, the cleaning cassette no longer cleans the heads.

You must use a new cassette.

3–38

VAX 4000 Model 300 Operation

3.2.1.1 Asynchronous Controllers Without Modem Support

Before using any peripheral device connected to a serial communications controller, check the following:

• Make sure the peripheral device is properly connected to the system.

• Make sure the peripheral device is properly installed, plugged into an appropriate power source, and turned on.

• Make sure the peripheral device is properly set up. Set-up involves choosing how the device operates. Some set-up choices are matters of personal choice, for example, the number of columns that display on a terminal screen. Others, like baud rate (a measure of the speed at which data is transmitted over a data line), must match the system setting if the peripheral device and system are to communicate. Refer to your terminal or printer manual for complete set-up instructions.

Generally, the default settings for your terminal are acceptable.

While most default settings are acceptable, you should perform the setup procedure for your terminal to ensure appropriate set-up values.

The two examples below provide set-up instructions for VT300-series and VT400-series terminals:

3.2.1.2 Asynchronous Controllers With Modem Support

Using serial devices with modem support requires that you install two modems: one connected to the system and one connected to the remote terminal. Both must be connected to phone lines.

Before using modems with your system, check the following:

1.

Make sure each modem is connected to the system.

2.

Make sure the modem is properly installed and connected to a phone jack.

3.

Set controls on the modem according to instructions in the modem user’s guide.

Before using the modem connected to the remote terminal, check the following:

1.

Make sure the modem is properly installed and connected to a phone jack.

2.

Set controls on the modem according to instructions in the modem user’s guide.

3.

Check the settings on the terminal attached to the modem. Depending on the type of modem and the type of lines used, the baud rate may be 300, 1200, or 2400. Other settings should be the same as those described in the previous section.

Before using a phone line with modem support, you must set certain parameters such as line speed.

See your system software manuals for details.

3.2.2 Synchronous Controllers

The following synchronous controllers are available for your VAX 4000 system:

• DIV32—DEC Integrated Services Digital Network (ISDN) controller

• DPV11—Single-line programmable controller

• DSV11—Dual-line controller

3–40

VAX 4000 Model 300 Operation

• KMV1A—Programmable communications interface, Q-bus controller

Before using a synchronous controller you must verify the following:

• The system you want to communicate with has an appropriate synchronous controller.

Synchronous communications require a synchronous controller on both the transmitting and receiving system.

• Both the transmitting and receiving systems must have supporting host software installed. Synchronous communications operate under specific protocols that define how data is interpreted. Two common protocols are X.25 and PSI. Appropriate host software is required to interpret the protocol.

3.2.3 Network Controllers

NOTE:

VAX 4000 systems contain an Ethernet controller embedded in the

CPU module.

You can have a second optional Ethernet controller, the

DESQA module, included with your system.

Before using a network controller you must do the following:

1.

Make sure the Ethernet cable (either standard transceiver cable or

ThinWire cable) is connected to the console module (or optional DESQA module). The light next to the connector should be lit, indicating an active connection. If not lit, move the Ethernet Connector switch to the proper position.

Operating the System Options

3–41

2.

Make sure the Ethernet cable is properly connected to the network. A transceiver cable can be connected in one of the following ways:

• To an H4000 or H4005 transceiver located on a traditional Ethernet

• To a local network interconnect (DELNI), which can be connected to a larger Ethernet or can serve to connect up to eight systems in a local area network

A ThinWire cable can be connected as follows:

• To a ThinWire Ethernet multiport repeater (DEMPR) or ThinWire single port repeater (DESPR), which can be connected to a larger

Ethernet or can serve to connect many systems in a local area network

• To an available connection on a T-connector of other ThinWire nodes

3.

Have the DECnet application installed on your system.

4.

Register your node with the network manager so that your node is recognized by other systems in the network.

Some software products, for example, Ethernet-based VAXcluster systems, use the Ethernet hardware address of other systems to operate properly.

To find the hardware address of your Ethernet device, use the command

SHOW ETHER from console mode. The hardware address of your Ethernet device displays on the terminal as shown in the following example:

>>>

SHOW ETHERNET

EZA0 (08-00-2B-03-50-5C)

Refer to your software manuals and DECnet manuals for other requirements and further instructions on using a network connection.

Appendix B

Programming Parameters for DSSI

Devices

This appendix describes the console mode procedures for setting and examining parameters for DSSI devices.

NOTE:

Before you reprogram DSSI devices, you should have a good understanding of DSSI architecture and VAXcluster software operation. If you do not have that understanding, you should read the VMS manuals listed in Appendix A or call your Digital service representative.

Two types of DSSI storage adapters are available for VAX 4000 systems: an embedded DSSI host adapter, which is part of the CPU, and the

KFQSA storage adapter. The KA670 CPU has two embedded DSSI storage adapters: bus 0 and bus 1.

Each storage adapter provides a separate DSSI bus that can support up to seven DSSI devices (six DSSI devices for a dual-host configuration). The adapters make a connection between the CPU and the requested device on their respective DSSI bus. Each DSSI device has its own controller and server that contain the intelligence and logic necessary to control data transfers over the DSSI bus.

B.1 DSSI Device Parameters

Six principal parameters are associated with each DSSI device:

• Bus Node ID

• ALLCLASS

• UNITNUM

• FORCEUNI

• NODENAME

• SYSTEMID

Programming Parameters for DSSI Devices

B–1

NOTE:

Each of the above parameters, with the exception of the Bus Node

ID, are programmed and examined using the console-based Diagnostic and Utility Program (DUP) driver utility. The Bus Node ID is physically determined by the numbered bus node ID plug that inserts into the device’s front panel.

A brief description of each parameter follows:

The Bus Node ID parameter is provided by the bus node ID plug on the device’s front panel. Each DSSI bus can support up to eight nodes, 0–7.

Each DSSI adapter and each device count as a node. Hence, a DSSI bus can support up to seven devices, bus nodes 0–6 (with node 7 reserved for the storage adapter); in a dual-host configuration up to six devices, 0–5

(with nodes 6 and 7 reserved for the storage adapters). Refer to Chapter 3 for instructions on changing bus node ID plugs.

The ALLCLASS parameter determines the device allocation class. The allocation class is a numeric value from 0 to 255 that is used by the VMS operating system to derive a path-independent name for multiple access paths to the same device. The ALLCLASS firmware parameter corresponds to the VMS SYSGEN parameter ALLOCLASS.

DSSI devices are shipped from the factory with a default allocation class of zero. Each device to be served to a cluster should have a nonzero allocation class that matches the allocation class of the system. Refer to the VMS

VAXcluster manual for rules for specifying allocation class values.

The UNITNUM parameter determines the unit number of the device. By default, the device unit number is supplied by the bus node ID plug on the device’s front panel. Systems with multiple DSSI busses, as described later in this section, require that the default values be replaced with unique unit numbers. To set unit numbers and override the default values, you use the console-based DUP driver utility to supply values to the UNITNUM parameter and to set a value of zero to device parameter FORCEUNI.

The FORCEUNI parameter controls the use of UNITNUM to override the default device unit number supplied by the bus node ID plug.

When

FORCEUNI is set to a value of zero, the operating system uses the value assigned to the UNITNUM parameter; when FORCEUNI is set to a value of one, the operating system uses the value supplied by the bus node ID plug.

The NODENAME parameter allows each device to have an alphanumeric node name of up to eight characters. DSSI devices are shipped from the factory with a unique identifier, such as R7CZZC, R7ALUC, and so on. You can provide your own node name.

B–2

VAX 4000 Model 300 Operation

The SYSTEMID parameter provides a number that uniquely identifies the device to the operating system. This parameter may need to be modified only when replacing a device. Only Customer Services representatives and qualified self-maintenance customers can remove devices.

B.2 How VMS Uses the DSSI Device Parameters

This section describes how the operating system uses the parameters to form unique identifiers for each device. Configurations that require you to assign new unit numbers for devices are also described.

With an allocation class of zero, the operating system can use the default parameter values to provide each device with a unique device name. The operating system uses the node name along with the device logical name in the following manner:

NODENAME$DIAu where:

NODENAME is a unique node name and u is the unit number.

With a nonzero allocation class, the operating system relies on unit number values to create a unique device name. The operating system uses the allocation class along with the device logical name in the following manner:

$ALLCLASS$DIAu where:

ALLCLASS is the allocation class for the system and devices, and u is a unique unit number.

Using mass storage expanders, you can fill multiple DSSI busses: busses 0 and 1 supplied by the KA670 CPU, and a third and fourth DSSI bus using the KFQSA storage adapter. Each bus can have up to seven DSSI devices

(bus nodes 0–6). When more than one bus is being used, and your system is using a nonzero allocation class, you need to assign new unit numbers for devices on all but one of the DSSI busses, as the unit numbers for all DSSI devices connected to a system’s associated DSSI busses must be unique.

Figure B–1 illustrates the need to program unit numbers for a system using more than one DSSI bus and a nonzero allocation class. In the case of the nonzero allocation class, the operating system sees three of the ISEs as having duplicate device names, which is an error, as all unit numbers must be unique.

NOTE:

Digital recommends that you configure your systems to have unique unit numbers even if you have a standalone system using an allocation class of zero. This practice will avoid problems with duplicate device names if you later decide to form a cluster.

B.3 Examining and Setting DSSI Device Parameters

The following instructions describe how to change DSSI parameters, using the DUP driver utility. In the example procedures, the allocation class will be set to 2, the devices for bus 0 (in the VAX 4000) will be assigned new unit numbers (to avoid the problem of duplicate unit numbers), and the system disk will be assigned a new node name.

B.3.1 Entering the DUP Driver Utility

To examine and change DSSI parameters, you must first activate the DUP driver utility by setting host to the specific device for which you want to modify or examine parameters.

Use the following command for embedded DSSI:

SET HOST/DUP/DSSI/BUS:<BUS_NUMBER> <NODE_NUMBER> PARAMS where:

<bus_number> is the DSSI bus number (0 or 1), and <node_number> is the bus node ID (0–6) for the device on the bus.

Use the following command for KFQSA-based DSSI:

SET HOST/DUP/UQSSP/DISK <controller_number> PARAMS where:

<controller_number> is the controller number (provided by the SHOW

UQSSP display) for the device on the bus.

B–8

VAX 4000 Model 300 Operation

Appendix C

Backup Procedures

This appendix describes the following procedures:

• Installing and booting standalone BACKUP on the system disk

• Installing and booting standalone BACKUP on a TK50 tape cartridge

• Backing up and restoring the system disk

C.1 Overview of Standalone BACKUP

The Backup utility lets you create and restore backup copies of files, directories, and user disks. Because the Backup Utility copies only what is on the disk and ignores sections of any open files contained in memory, you should use it to back up user disks, not the system disk. If you use the Backup Utility to back up the system disk, the portions of the files that were in memory and data about files not yet written back to the disk (cache) will not be recorded on the resulting backup copy.

Use standalone BACKUP to make a complete backup of the system disk.

Standalone BACKUP is a version of the Backup Utility that runs without the support of the entire VMS operating system. Before you use standalone

BACKUP, you must shut down the VMS operating system. The shutdown procedure sends the contents of the caches back to the disk and closes any open files. By shutting down the system and using standalone BACKUP, you can make an exact copy of the system disk.

You can keep standalone BACKUP on the system disk, a TK50 tape cartridge, or any other media the system supports. Digital recommends that you keep standalone BACKUP on the system disk and on a tape cartridge.

Usually you boot standalone BACKUP from the system disk because it saves time. You should, however, keep a copy of standalone BACKUP on a tape cartridge in case the system disk becomes damaged.

Backup Procedures

C–1

C.1.1 Installing Standalone BACKUP on the System Disk

You can install standalone BACKUP in any available root directory on the system disk from [SYS1] to [SYSE]. However, Digital has established

[SYSE] as the standard directory for standalone BACKUP.

To install standalone BACKUP in [SYSE] on the system disk, use the following procedure:

1.

Log in to the SYSTEM account.

2.

Enter the following command:

$ @SYS$UPDATE:STABACKIT SYS$SYSDEVICE:

Return

The procedure places the files in the directories [SYSE.SYSEXE] and

[SYSE.SYS$LDR] on the system disk. It lists the files as they are copied. When the procedure finishes, the system displays the following message:

The kit is complete.

3.

To boot standalone BACKUP from the system disk, see Section C.1.2.

C.1.2 Booting Standalone BACKUP from the System Disk

To boot standalone BACKUP from the system disk, use the following procedure:

1.

If the VMS operating system is not running, go to step 2.

If the VMS operating system is running, enter the following command to shut down the system:

$ @SYS$SYSTEM:SHUTDOWN

Return

Answer the questions. When the procedure asks if an automatic system reboot should be performed, press Return for No. When the procedure is finished, the system displays the following message:

SYSTEM SHUTDOWN COMPLETE - USE CONSOLE TO HALT SYSTEM

2.

Stop the system by pressing the Halt button on the SCP.

3.

Enter the BOOT command in the following format:

>>>B/E0000000 device_name

Return

Substitute the device name of the system disk for device_name

19-APR-1991 13:00:00.00

$

9.

Remove the tape cartridge containing standalone BACKUP from the tape cartridge drive.

To back up the system disk, see Section C.2.

To restore the system disk, see Section C.3.

C.2 Backing Up the System Disk

The reasons to back up a system disk are:

• In case a problem occurs during a VMS upgrade or update, or during the installation of other software products: Before you attempt any of these procedures, you should back up the system disk. If a problem occurs, you can restore the backup copy of the system disk.

• To prevent loss of system files if they are deleted accidentally: After you install or upgrade the VMS operating system or any other software products, you should back up the system disk. If a system file is deleted and renders the system disk inoperable, you can restore the backup copy and continue to use the system.

• In case the system disk malfunctions: If you have a backup copy of the VMS operating system, you can restore it to a functioning disk and continue to use the system.

• To eliminate disk fragmentation: Fragmentation happens when files are not stored contiguously on the disk. Back up the system disk to a tape cartridge, diskettes, or another disk. Then restore the files to the original system disk. The BACKUP command creates a copy on which files are stored contiguously.

Digital recommends that you use standalone BACKUP, which uses a subset of Backup utility qualifiers, to back up and restore the system disk. It is especially important that you understand the functions of the /IMAGE and

/PHYSICAL qualifiers to the BACKUP command before using standalone

BACKUP. Table C–1 summarizes the standalone BACKUP qualifiers.

C–6

VAX 4000 Model 300 Operation

Table C–1: Standalone BACKUP Qualifiers

Qualifier Function

/IMAGE

/PHYSICAL

Allows you to create a functionally equivalent copy of the entire system disk

Copies, saves, restores, or compares the entire system disk in terms of logical blocks, ignoring any file structure

For a complete description of the Backup utility and its qualifiers, see the

VMS Backup Utility Manual.

To back up the system disk, use the following procedure:

1.

Decide whether you want to back up the system to another fixed disk or to a tape cartridge. If you are using a tape cartridge, obtain a scratch tape that you can use for the backup copy. A scratch tape cartridge is a tape cartridge that is either blank or contains files that you no longer need.

2.

If you are using a tape cartridge, write-enable it. To write-enable a tape cartridge, slide the write-protect switch away from the tape cartridge label. Insert the tape cartridge in the tape cartridge drive.

3.

Determine the device name of the drive holding the system disk and the drive holding the backup disk or tape cartridge. Enter the SHOW

DEVICE command at the console prompt (>>>).

4.

Boot standalone BACKUP as described in Section C.1.2 or Section C.1.4.

5.

Enter the BACKUP command in one of the following formats:

$ BACKUP/IMAGE/VERIFY source_drive: target_drive:

Return

$ BACKUP/IMAGE/VERIFY source_drive: target_drive:-

Return

-$ saveset.BCK/LABEL=volume_label/REWIND

Return where:

• source_drive is the location of the files that you want to back up.

Use the device name of the drive holding the system disk.

• target_drive is the destination. Use the device name of the drive holding the backup disk or tape cartridge.

• saveset.BCK

is the name of the saveset (the name should reflect the contents of the backup tape and cannot exceed 17 characters in length).

Backup Procedures

C–7

• volume_label is the volume label of the tape cartridge in the tape drive. If the tape has been initialized already, use the same volume label that was assigned by the INITIALIZE command. If the tape has not been initialized, you can assign a volume label at this time.

The volume label cannot have more than six characters.

The following example uses the BACKUP command to make a backup disk. You can use a backup disk as the system disk:

$ BACKUP/IMAGE/VERIFY DIA0: DIA1

Return

The following example uses the BACKUP command to make a backup tape cartridge.

The contents of the backup tape cartridge must be restored to a disk before you can use them. For more information, see Section C.3.

$ BACKUP/IMAGE/VERIFY DIA0: MUA0:-

Return

-$ APR_19_1991.BCK/LABEL=19APRF/REWIND

Return

6.

The system displays the following message:

%BACKUP-I-STARTVERIFY, starting verification pass

7.

If you are backing up the system disk to another disk, proceed to step

8.

If you are backing up your system disk to a tape cartridge and the contents of the system disk fit on one tape cartridge, remove the backup tape cartridge from the drive. Label the tape COMPLETE SYSTEM

BACKUP, number it, and include the date. Proceed to step 8.

If you are backing up your system disk to a tape cartridge and the system disk contains more data than one tape cartridge can store, the system displays the following messages:

%BACKUP-I-RESUME, Resuming operation on volume 2

%BACKUP-I-READYWRITE, Mount volume 2 on _MUA0: for writing

Enter "YES" when ready:

Do the following: a.

Remove the backup tape cartridge from the drive.

b.

Label the tape COMPLETE SYSTEM BACKUP, number it, and include the date.

c.

Write-protect the tape cartridge.

d.

Write-enable another scratch tape cartridge and insert it in the drive.

C–8

VAX 4000 Model 300 Operation

When you are ready to continue, enter Y (for Yes) and press Return.

The procedure displays the following message:

%BACKUP-I-STARTVERIFY, starting verification pass

Each time the procedure displays a mount request, follow steps a through e.

8.

When the procedure is finished, the system displays the following message:

%BACKUP-I-PROCDONE, operation completed. Processing finished at

19-APR-1991 15:00:00.00

If you do not want to perform another standalone BACKUP operation, use the console to halt the system.

If you do not want to perform another standalone BACKUP operation, ensure the standalone application volume is online and ready.

Enter "YES" to continue:

9.

Press the Halt button.

10. Reboot the system.

Store the backup tape cartridge in a safe place.

NOTE:

The BACKUP command creates a system disk that includes a

Digital-provided set of volume parameters, including a CLUSTER_SIZE

(disk access scheme) of value 1. (The CLUSTER_SIZE parameter refers to the way files are stored on the disk, NOT to VAXcluster environments.)

You can change most volume parameters later with the SET VOLUME command. However, to change the CLUSTER_SIZE parameter, you must back up the system disk that has been initialized previously with the

CLUSTER_SIZE value that you want. To prevent the BACKUP command from reinitializing the target disk, use the /NOINITIALIZE qualifier. For more information about initializing a disk, see the Guide to Maintaining a VMS System. For more information on the BACKUP command, see the

VMS Backup Utility Manual.

C.3 Restoring the System Disk

To restore the system disk from a tape cartridge, use the following procedure:

1.

Determine the device names of the drive holding the system disk and the drive holding the backup disk or tape cartridge. Enter the SHOW

DEVICE command at the console prompt (>>>).

Backup Procedures

Appendix D

Removing Unwanted VMS Files

D.1 Using VMSTAILOR

Read this appendix if you want to remove the VMS operating system and

DECwindows files that you do not need from the system disk. For example, if you are not running DECnet–VAX, you do not need the network support files. You can remove unwanted files with the VMSTAILOR program. Enter the following command to log in to the SYSTEM account:

$ RUN SYS$UPDATE:VMSTAILOR

Return

The VMSTAILOR program asks you if you want to tailor files ON or OFF.

Enter OFF to remove unwanted files.

CAUTION:

Do not delete files from the factory-installed software (FIS) system until you have backed up your software.

A VMS distribution kit is needed to return files to the system disk. Also, VMSTAILOR and

DECW$TAILOR procedures cannot restore files from a backup set. It may be necessary to reload the system software from a backup set if files are incorrectly deleted and if a VMS distribution kit is not available.

The VMSTAILOR program lists each group of files and its size in blocks.

Files are grouped according to their function. For example, all the files required for cluster support are in one group. A file group is made up of many small subgroups. You can eliminate an entire group of files or you can eliminate one or more of its subgroups.

Decide which file groups or subgroups you do not need to support your system. The VMSTAILOR program displays step-by-step instructions that are easy to follow.

VMSTAILOR displays the names of the files it deletes. After it finishes,

AUTOGEN runs automatically to make the adjustments that are necessary after system files are deleted.

NOTE:

You can use VMSTAILOR at any time to delete or add groups of

VMS files to the system disk. After adding files to the system disk, you should apply any updates that affect them.

Removing Unwanted VMS Files

D–1

For example, suppose you do not need the VMS Version 5.0 MAIL utility and you run VMSTAILOR to remove those files. Later on, if you decide you want to use mail, you can run VMSTAILOR to return the MAIL files to the system disk. You then apply any VMS upgrade or update that has occurred since Version 5.0 that affected the MAIL utility. To remove VMS

DECwindows files from the system disk, enter the following command:

$ RUN SYS$UPDATE:DECW$TAILOR

Return

The DECW$TAILOR program works just like the VMSTAILOR program.
