Features and Components

This chapter describes the SCEA in detail. SCEA features, components, and specifications are described in each section.

Features

The SCEA is a SCSI to SCSI workstation adapter which allows you to connect hard disk drives, erasable optical drives (without any software patches or special drivers), and tape drives to a workstation such as the VAXstation™

3100, DECstation™ 5000/200, Sun SPARCstation™, IBM RISC System/6000™

series, or Silicon Graphics IRIS INDIGO systems.

For purposes of this manual, the port connecting to the host computer (Jl on the SCEA) is called the Host SCSI Port; the port connecting to the target devices (J2) is called the Device SCSI Port. These target devices may include disk, tape, optical drives, jukeboxes, and tape stackers.

The host computer plays the role of initiator to the SCEA and SCSI devices, and the SCEA plays the role of target to the host computer at Jl. The SCEA, in turn, plays the role of initiator to SCSI devices from J2, the Device SCSI Port.

Features and Components 2-1

Removable Media

When enabled, a removable drive is reported as removable. For the

V AXstation 3100, the VMS dismount drive will eject the media if the drive is removable. Place jumper shunt in W12-6 to enable this feature as shown in Table 2-1.

NOTE Do not use this feature with SCEAIJl or SCEAIJ2 for jukeboxes. When selected, the media will eject from the drive and you will not be able to access it inside the jukebox.

Multi-Hosting for VMS

CMD's multi-host solution can support disk, tape, and optical devices

including jukeboxes for VMS only. It gives you the ability to completely share an array of disks and tapes between multiple VAX systems running VAX

cluster software. Multi-hosting configuration instructions are given in Chapter 4. Refer to Appendix A for supported disk and tape devices.

SCSI Library Manager

The SCSI Library Manager (SLM or SLM/Unix) is an optional application software license that works exclusively with the SCEA for VAX/VMS and Unix systems.

SCEA

SCSI Library Manager was designed to work with multiple jukeboxes as well as a single jukebox with from one to five erasable optical or WORM drives installed. With just a few keystrokes, SLM controls all basic operations like inserting, removing, and flipping erasable or WORM cartridges from the drive unit.

In addition to giving you complete control of jukebox functions, SLM also has a build-in callable user interface allowing you to customize SLM to your requirements. This is especially useful for applications to support file

management. Refer to SLM or SLM/Unix Management Guides for installation and operation.

SCEA Models

The SCEA is sold in three basic versions: SCEA/E, SCEA/C and SCEA/J.

Although the basic SCEA is identical for each version, the function of the SCEA board is determined by the firmware installed by CMD during its final test. It is important that YOll understand the functions provided by each SCEA version as listed in this section. SCEA models and CMD model numbers are as listed in Table 2-3.

Devices Supported

Supports 2 drives (LUN 0 and 1)

Supports 7 drives (LUN 0, 1,2, 3, 4, 5, and 6) Supports a jukebox of one drive up to 32 slots (LUN 0, 1,2, 3,4, 5, and 6)

Supports a jukebox of more than one drive and more than 32 slots (LUN 0, 1,2,3,4,5, and 6)

The SCEA/E firmware is designed to provide a transparent hardware interface solution for erasable optical (MO) disks, 4-mm and 8-mm helical

Features and Components 2-3

scan tape drives, nonsystem-supported SCSI Winchester disk drives and other special SCSI peripheral devices without requiring patches or drivers to the host workstation operating system. SCEA/E does this by causing the SCSI peripheral to emulate a generic Winchester system disk or tape drive. The SCEA board and firmware recognizes the attached peripheral, then selects the .most appropriate device emulation type. SCEA/E supports up to two SCSI

peripherals.

The SCEA/C firmware provides expansion capabilities for your workstation's SCSI port. The SCEA/C provides SCSI LUN (Logical Unit Number) support for up to seven SCSI devices for each SCSI ID used. One SCEA/ C is required for each SCSI ID to be expanded. Multiple SCEA/Cs can be used to support up to a total of 49 SCSI devices per SCSI port. The SCEA/C also provides multi-hosting and peripheral sharing capabilities for DEC VMS-based V AXstations. The SCEA/ C also provides a "SCSI Pass-Through" mode for those applications where driverless operation is not desired or required; both

"pass-through" and SCEA/E hardware driver supported devices can be used on the same SCEA/C board (no additional SCEA board is required).

The SCEA/J firmware combines the capabilities of the SCEA/E and SCEA/C to provide a seamless integration solution for interfacing optical disk

jukeboxes, 4-mm and 8-mm tape cartridge handling systems, and most SCSI-based robotic devices when used in conjunction with CMD's SCSI Library Manager (SLM) software package.

Two versions of the SCEA/J firmware are available to support low-end (SCEA/Jl) and high-end (SCEA/J2) jukeboxes. SCEA/Jl supports one drive and 32 media slots or less and CMD's SLM Jl or SLM/lJnix Jl software license. SCEA/J2 supports up to six drives and 128 slots and CMD's SLM J2 or SLM/Unix J2 software license. The SCEA/Jl version will not accept commands from an SLM/Unix J2 software license, and vice versa. For more detail, refer to the SLM/Unix Management Guide.

The SCEA contains two 50-pin SCSI ports. One of the ports is connected to the host computer, the other to the target devices. When the SCEA and the SCSI devices are installed in the same cabinet which meets EMI/RFI shielding requirements, a 25-signal twisted-pair cable must be used for connecting the SCEA (J2) and the SCSI devices. When the SCEA and the SCSI devices are installed in separate cabinets, a shielded SCSI cable should be used to meet FCC requirements.

A minimum conductor size of 28 AWG shall be used to minimize noise effects and ensure proper distribution of optional terminator power. The maximum cable length is 6.0 meters or 20 feet in single-ended mode.

Features and Components 2-7

Host SCSI Port

The Host SCSI Port, J1, on the SCEA is a 50-pin single-ended SCSI connector which connects to the SCSI port of the host computer (workstation). To the host computer, the SCEA looks very much like an ordinary target device.

Each device (initiator or target) on the SCSI bus requires a unique SCSI Identification address (specifically SCSI ID 0-7). SCSI ID 7 has the highest priority on the bus and SCSI ID 0 has the lowest priority. The SCEA is factory configured to SCSI ID 0 at J1. You can change this ID by selecting a SCSI ID for the SCEA that is not currently being used on the system (to check SCSI ID number perform show dev dk, for example, on V AXstation 3100). See

Chapter 3 for SCSI ID selections from on-board jumpers.

For example, if the target device is to be seen as SCSI ID 2 by the host, set the SCEA to SCSI ID 2 (by configuring the SCEA described in Chapter 3) and the target device to SCSI ID

o.

The SCEA and target device will be seen by the host as one device, SCSI ID 2 or DKA200 on the V AXstation 3100 (using show dev dk).

Host SCSI Port Termination

Terminator resistors, RN1, RN3, and RN4, are removable 220/330-ohm terminator resistor packs for the J1 Host SCSI Port. SCSI bus specifications require the cable to be terminated at both physical ends. Termination is usually required at J1 on the SCEA except in the V AXstation 3100 and DECstation™

5100. See Chapter 3 for proper installation instructions.

The SCEA can supply power to the TERMPWR (pin 26) of the SCSI connector J1 through a diode, a fuse (F1), and a jumper (WI). Since the SCEA plays the target role, it should not have to supply TERMPWR, therefore, WI should be out. However, if the host computer does not supply termination power, place jumper shunt on WI (see Chapter 3 for installation instructions).

Device SCSI Port

The Device SCSI Port, J2, on the SCEA is a 50-pin single-ended SCSI connector which connects to the target devices. The SCEA is factory configured to SCSI ID 7 at J2. See Chapter 3 for Device SCSI Port ID settings from on-board jumpers.

Since the SCEA is factory configured to SCSI ID 7 (at J2), the SCSI ID of the target devices connected to the SCEA should be set from SCSI ID 0 to 6 starting at SCSI ID O. For the V AXstation 3100, only one drive is initially

SCEA

supported, and the drive SCSI ID must be 0; others may be manually set using the Sysgen Connect Statement. For the Sun SP ARCstations and SPARCservers, the SCSI ID should start at O. Up to 7 drives are supported.

Device SCSI Port Termination

Terminator resistors, RN17, RN18, and RN19, are removable 220/330-ohm terminator resistor packs for the J2, Device SCSI Port. The SCSI bus

specifications requires the cable to be terminated at both physical ends of the SCSI bus. It is recommended that these resistors remain in place if this connector is at one physical end of the cable.

The SCEA supplies terminator power to the TERMPWR pin (pin 26) of SCSI connector (2) through a fuse (F2), a diode, and jumper block W19. To install terminator power, install W19. W19 should remain installed since the J2 SCSI port acts like an initiator to the target devices on the bus.

Any SCSI terminator (on-drive or external) needs to be powered by at least one SCSI device, otherwise the SCSI signals will be pulled down. Typically, an initiator (SCSI host adapter) provides the power to the on-board

terminator, the external SCSI terminator, or the on-drive terminator when the drive is powered ^OFF.

Anytime an external SCSI terminator (instead of an on-drive SCSI terminator) is used, the SCSI terminator power option of the SCEA has to be enabled at jumper shunt W19.

Installation

Installation of the SCEA may vary with each application. The SCEA may be installed inside the chassis of the SCSI device if space constraints allow, inside a storage box like the DEC BA42 Storage Expansion Box, inside a jukebox like the IDE 9000 or inside a dedicated peripheral enclosure. This section details installing the SCEA and its respective SCSI devices.

Installing the SCEA into a Storage Box, Shoebox, or System

To install the SCEA follow these instructions carefully.

1 Turn the host computer completely OFF and unplug the power cord from the wall.

2 Carefully unpack the SCEA and place on a non-metallic surface.

WARNING Be sure to wear anti-static wrist straps or equivalent to protect the SCEA from electro-static damage.

Installation 3-1

3 Carefully install the SCEA into an assigned slot inside a storage box, shoebox, or system, see Figure 3-1 for an example.

WARNING 0 Make sure the SCEA or any of its components are NOT directly connected to or touching metal surfaces; attach plastic washers on BOTH sides of the mounting screws.

Configuration

This chapter details software configuration for the system to recognize devices located on the SCSI bus, the On-Board Utility to assist you in setting up the SCEA and your system and multi-hosting configuration for VMS. Remember, each device on each SCSI bus must have a unique SCSI ID number.

VMS, VAXstation Configuration

Your VMS system will auto-configure only LUN 0 for each SCSI ID; through the SCEA VMS recognizes the target device with SCSI ID 0 as LUN O. Other devices LUN 1 to LUN 7 connected to the SCEA must be manually configured to the system using the VMS Sysgen Connect Statement.

Follow these instructions to configure your system for more than one LUN:

1 Be sure all cables are securely connected and termination is correct. See Sections "Installing the SCEA" and "Installing SCSI Devices."

2 Power "ON" and boot the system.
