Figure 1: The RWZ01 Disk Drive

Chapter 1
Overview
This chapter contains an overview of the features and functions of the
RWZ01 Disk Drive (see Figure 1) and provides cautions on its use.

1.1 Features
The RWZ01 Disk Drive is an external storage device that uses large
capacity removable disks and has the following features:
•

A write/read disk using magneto-optical recording with a multiple
write capability.

•

A large capacity disk (590 MB, 512 bytes/sector, excluding alternate
areas).

•

A disk format that complies with the Continuous/Composite Servo
(CS) format (ISO/IEC DIS 10089) of International Standard Organization (ISO), which is the world standard.

•

A Small Computer System Interface (SCSI) which complies with
ANSI X3.131-1986, CCS Rev.4B. Up to eight units, including the
host computer, can be connected to one SCSI bus.

•

A high-speed transmission of data using a 2400 rpm spindle motor.

Overview 1–1

•

A fast seek time of 95 ms using the thin, light-weight optical pick-up.

•

An error correction using Long Distance Code.

1.2 System Configuration
The RWZ01 is Small Computer System Interface (SCSI) compatible and
therefore can be connected to the host computer SCSI bus or to any
SCSI unit in the system. Figure 1-1 shows a system configuration with
a VAXstation 3100 as the host computer.

Figure 1–1: System Configuration Using VAXstation 3100

A SCSI terminator (terminal resistance) is built into the RWZ01 Disk
Drive. With this, the RWZ01 can be connected as either an intermediate
or terminating device. When the RWZ01 is the last device (terminating
device) on the SCSI bus, set switches 3 and 4 to ENABLE (see Section
2.4, Setting Switchpack Switches).

1.3 RWZ01 External Components
The following sections describe the external components on the front and
the rear of the RWZ01.

1–2 Overview

1.3.1 Front
The names and functions of the parts on the front of the RWZ01 are (see
Figure 1-2):
Figure 1–2: Front of RWZ01 Disk Drive

1. Power supply indicator This indicator is lit when power is on.
2. BUSY indicator This indicator is lit when data is being read or written to the disk.
3. Disk insertion entrance This is where you insert a disk (see Figure 3-2).
4. Air intake duct for cooling This duct takes in air to cool the interior.
5. Emergency eject hole This is used for emergency ejection of a disk (see Chapter 4, How to
Handle Failures).
6. EJECT button This is the button to press when removing a disk from the RWZ01.

Overview 1–3

1.3.2 Rear
The names and functions of the components on the rear of the RWZ01
are described in the following (see Figure 1-3). See Chapter 2 for a
description of the use of these components.
Figure 1–3: Rear of RWZ01 Disk Drive

1. Interface connector This is the connecting point of the RWZ01 to the SCSI bus. Use a
SCSI cable (sold separately) to connect to the host computer or other
SCSI unit (see Section 2.2, Connections).
2. Switchpack Switches This set of switches controls the operation of the RWZ01 and its SCSI
ID number (see Section 2.4, Setting Switchpack Switches).
3. Air exhaust duct for heat release This is the cooling air exhaust duct.
4. F.GND pin This F.GND pin is not used by the RWZ01 because a 3-pin (with
ground) power cable is used.
1–4 Overview

5. AC Input Power Connector This connects to the ac input supply with the 3-pin (with ground)
power cable.
6. AC Power Switch This switch turns the ac power on or off.

1.4 Cautions on Use
Note the following points to use the RWZ01 safely.
•

AC Input Power — Use 100 to 120 Vac, 50/60 Hz supply voltage for USA, Japan, and
Canada.
Use 220 to 240 Vac, 50/60 Hz supply voltage for European
countries.
— Do not connect to an ac power line that includes a large power
consumption device such as a copier or shredder.

•

Shock and vibration The RWZ01 is susceptible to damage from shock or vibration.

•

Installation location Operate the RWZ01 in the horizontal position. A failure may occur
when it is not operated in the horizontal position.
Do not operate or store the RWZ01 in locations with the following
conditions (see Appendix A, Specifications):
— Severe temperatures changes
— Direct sunlight
— Strong magnetic field or gas
— Electrostatic or noise discharges
— High humidity
— Dust

•

Airflow Do not place the RWZ01 in a location with poor airflow. Do not cover
the cooling air intake or exhaust ducts.

Overview 1–5

•

Condensation — Avoid sudden temperature change to avoid condensation.
— Remove a disk as soon as condensation is suspected. To remove
condensation within the unit turn the RWZ01 power on without
inserting a disk.

•

Moving Do not move the RWZ01 during operation because the disk is rotating
at a high speed and may be damaged. Stop the operation, remove
the disk and then move the RWZ01.

•

Handling failure If a failure occurs, remove the ac power cable from the power source
and contact the Digital Equipment Corporation service representative.

•

Cleaning an optical head Dirt on the lens of the optical head can cause a read or write error.
Clean the lens once a month using a lens cleaning cartridge. See
Chapter 4 for information on using a lens cleaning cartridge.
Notes
1. Use an RWX1K-01 disk with the RWZ01.
2. Execute the DISMOUNT (unmount) command before removing a disk (see Section 3.4, Dismounting and Removing a Disk).
Removing a disk while data is being written to the disk interrupts the operation.
3. In the RWZ01, new data is written after old data is erased.
Therefore, the time required for reading is different from that
required for writing.

1–6 Overview

1.5 Laser Radiation
The RWZ01 Disk Drive is a Class 1 laser product. Since the laser beam
is completely enclosed, no harmful light is emitted during operation or
normal maintenance. However, when any operation or adjustment is
performed outside of the methods specified in this manual, exposure to
dangerous laser emissions may occur.

1.6 Disk
The RWZ01 treats each side of the disk as a separate volume (file area).
Use side A and side B of a disk as separate volumes. The disk is inserted
with the label of the side used facing up.

1.6.1 Data Protect Switch (Tab)
The DATA PROTECT (red) switch (see Figure 1-4) on the disk prevents
the inadvertent writing of data. To write protect the disk, move the red
switch in the direction of the arrow. To write enable the disk, move the
red switch in the opposite direction of the arrow.
Figure 1–4: Disk Data Protection Switch (Tab)

Overview 1–7

1.6.2 Condensation
Do not use the disk in a location with great temperature variation or
high humidity—condensation may prevent the writing and reading of
data.

1.6.3 Disk Maintenance
Use the following guidelines for proper disk maintenance.
•

Store disks in the plastic case provided.

•

Do not store disks in a dusty area, in direct sunlight, near a heater,
or in a humid area.

•

Do not place disks on a dashboard or tray in a car.

•

Do not place disks in a location affected by strong magnetic fields or
volatile gas.

•

Do not leave a disk inside the drive unit when not being used.

Figure 2–2: Connecting the RWZ01 Disk Drive

Installation 2–3

When the RWZ01 is connected to the host computer SCSI bus the side of the
RWZ01 connected to the cable is automatically the SCSI IN connector and the
other side is the SCSI OUT connector. To connect the RWZ01 Disk Drive to
the SCSI bus, perform the following:
1. Disconnect power to the host computer and the RWZ01.
Notes
1. Up to eight SCSI devices, including the host computer,
can be connected to one SCSI bus.
2. The total cable length connecting the SCSI devices on a
SCSI bus cannot exceed 6 m.

2. Make sure that the SCSI ID for the RWZ01 is unique for that SCSI
bus (see Section 2.4, Setting Switchpack Switches).
3. If the RWZ01 is the last SCSI device on the SCSI bus, set the
switches of the TERMINATOR and TERMINATOR POWER switches
to ENABLE (see Section 2.4, Setting Switchpack Switches).
4. Connect the SCSI cable to the connector and secure it with the
connector latches (wire loops).

2.3 Checking a SCSI ID Number
Check to ensure that the SCSI ID number set by the switchpack switches
is recognized by the host computer. The following sections have examples
for VMS and ULTRIX operating systems.
In these examples, the SCSI ID number is set to 3 of the SCSI bus
(external bus). See the host computer manual for a description of the
SCSI bus.

2.3.1 Operation for VMS
For VMS systems, use the console command mode SHOW DEVICES
command.
>>> SHOW DEVICES

The system will display a list of the devices connected to the host and
their ID numbers. If the RWZ01 is not displayed with the SCSI ID
number that was set, set the SCSI ID number of the RWZ01 again. First
turn off the ac power to all the devices on the SCSI bus.
2–4 Installation

2.3.2 Operation for ULTRIX
Confirm the connected device. See the appropriate ULTRIX System
Manual for the console command.

2.4 Setting Switchpack Switches
Switches 1 through 5 DISABLE (up) or ENABLE (down) the RWZ01
functions they control. Switches 6 through 8 set to 1 (up) or 0 (down) to
set the SCSI ID number of the RWZ01 (see Figure 2-3).
If the RWZ01 is connected to the SCSI bus, disconnect the ac power to all
the SCSI devices on that SCSI bus before changing the switch settings.
When delivered from the factory, switches 1 through 3 and 5 are set to
ENABLE (down) and switch 4 is set to DISABLE (up). The functions of
switches 1 to 5 are described in the following:

Figure 2–3: Setting the RWZ01 Switchpack Switches

1. AUTO SPIN UP (1) - The default is ENABLE.
When enabled, this switch sets the spindle motor (motor that rotates
the disk) so that it rotates automatically when you insert a disk.

Installation 2–5

2. MANUAL EJECT (2) - The default is ENABLE.
When enabled, this switch enables the EJECT button for removing
a disk.
3. TERMINATOR POWER (3) - The default is ENABLE (the RWZ01 is
the terminating SCSI bus device).
This switch controls whether the RWZ01 or some external device
supplies SCSI power to the SCSI terminator. (If the built-in RWZ01
terminator is used, an external SCSI terminator is not required.)
When the RWZ01 is the terminator unit, it supplies power to the
SCSI terminator.
•

Set the switch to ENABLE when the RWZ01 is the terminating
unit (see Figure 2–4).

Figure 2–4: When a Terminator is Used

2–6 Installation

•

Set the switch to DISABLE when the RWZ01 is not the terminating unit (see Figure 2–5).

Figure 2–5: When a Terminator is not Used

4. TERMINATOR - Default is DISABLE
This switch controls the use of the RWZ01 built-in terminator.
•

When the RWZ01 is the terminating unit (see Figure 2–4), set
the switch to ENABLE.

•

When the RWZ01 is not the terminating unit (see Figure 2–5),
set the switch to DISABLE.

5. PARITY - Default is ENABLE.
When set to ENABLE, the RWZ01 performs parity checking. This
switch must be set to ENABLE.

Installation 2–7

2.4.1 Setting a SCSI ID number
Use the three ID SELECT switches (6 through 8) to set the SCSI ID
number (0 through 7) of the RWZ01. For these switches, up (ID SELECT)
is on ( | ) and down is off (0) (see Figure 2-6). When delivered from the
factory, the SCSI ID number is set to 0 (switches 6, 7, and 8 down). The
switch settings for the allowable SCSI ID numbers are shown in Table
2-1.

Before using a new disk, you must first initialize the disk. The following
example shows how to initialize a disk when the RWZ01, with a SCSI
ID of 1, is connected to the SCSI Bus using VMS and ULTRIX.

3.2.1 For VMS Operation
1. Insert a disk into the RWZ01 (see Figure 3–2).

3–2 Operation

Figure 3–2: Inserting a Disk

2. Enter the INITIALIZE command.
$ INITIALIZE DKB100 (volume label)

Where: DK is the disk, B is SCSI port B, 100 is the SCSI ID (1), and
(volume label) is the appropriate volume label.
See the VMS User’s Manual for more information about the INITIALIZE
command.
Notes
1. The RWZ01 treats each side of the disk (A and B) as separate
volumes.
2. When a disk is initialized, the contents of the disk are lost.
3. Specify the SCSI ID number as the number set by switchpack
switches 6, 7, and 8.

Operation 3–3

3.2.2 Operation for ULTRIX
1. Insert a disk in the RWZ01 (see Figure 3–2).
2. Initialize a disk using the newfs(8) command.
# newfs /dev/rrz1c rwz01

For information about the ULTRIX newfs(8) command, see the ULTRIX
Guide to Disk Maintenance.

3.3 Mounting a Disk
Before using the disk, mount it on the host system. The following
examples show how to mount the RWZ01 with a SCSI ID of 1 using
VMS and ULTRIX.

3.3.1 Operation for VMS
Enter the MOUNT command.
$ MOUNT DKB100 (volume label)

For information about the VMS MOUNT command, see the VMS System
Manager’s Manual.
