Introduction
This chapter provides an overview of the DECarray cabinet, and the SF3x and
SF7x series storage enclosures.

1.1 DECarray Overview
The DECarray is a storage rack cabinet designed to hold up to six SF-series
storage enclosures and one or two magazine tape ISEs.
The DECarray is intended to be installed on one or both sides of a system. All
operator control panels (OCPs) project through the front door of the storage
array to allow easy access.
The Digital Storage System Interconnect (DSSI) cables from the host cabinet
input/output (I/O) panel connect to the DSSI I/O panel at the bottom rear of
the storage array. The DSSI I/O panel supports as many as 16 individual DSSI
buses.

Introduction 1–1

Introduction
1.1 DECarray Overview
Viewing the DECarray from the front, note that the SF-series storage
enclosures and magazine tape ISEs are arranged in the DECarray cabinet as
follows (Figure 1–1):
•

The DECarray has four levels, each with two storage enclosure positions.
The levels are numbered from the bottom up. Looking from the front,
odd-numbered positions are on the left, and even-numbered positions are
on the right, as shown in Table 1–1

Table 1–1 DECarray Storage Positions
Level

Left Position

Right Position

•

Levels 1, 2, and 4 are reserved for SF-series storage enclosures only.
Storage enclosure upgrades are installed into these levels in the following
order: position 1, 2, 3, 4, 7, and 8.

•

Level 3 is reserved for magazine tape ISEs. Magazine tape ISE upgrades
are installed first in position 5, then in position 6.
Note
The position numbers are visible on the right and left chassis side rails
when the front and rear doors of the storage array are open.

Specifications for the DECarray are shown in Table 1–2.

Introduction
1.2 Storage Enclosure Overview

1.2 Storage Enclosure Overview
The SF-series storage enclosures come in two series: the SF3x enclosure that
contains up to 12 half-height, 3 1/2-inch ISEs, and the SF7x enclosure that
contains up to 4 full-height, 5 1/4-inch ISEs.
Each disk ISE within an SF-series enclosure is independently controlled
from the OCP on the front of the enclosure. A power supply in the enclosure
provides the dc power and cooling for all disk ISEs installed in the enclosure.
The SF3x storage enclosure (Figure 1–2) holds up to 12 RF3x series ISEs.
There are six slots in the front of the enclosure and six slots in the rear. Disk
ISEs installed in these slots plug directly into a backplane, which is cabled to
a connector tray on the top rear of the storage enclosure.
The SF3x enclosure can be configured in through-bus mode or split-bus mode.
In through-bus mode, the six ISEs in the front of the SF3x enclosure are
connected to a single DSSI bus, and the six ISEs on the rear of the SF3x
enclosure are connected to a second DSSI bus. In split-bus mode, each end
of the enclosure (front and rear) is further divided into left-side ISEs and
right-side ISEs, each connected to a separate DSSI bus. Thus, in split-bus
mode there are four DSSI buses, each with three drives connected to it.
The SF7x series storage enclosure (Figure 1–3) holds either two or four RF7x
series ISEs. The ISEs in the SF7x storage enclosure can also be configured
in split-bus or through-bus mode. In through-bus mode, all four disk ISEs
are connected to a single DSSI bus. In split-bus mode, the left-side ISEs are
connected to one DSSI bus, while the right-side ISEs are connected to a second
DSSI bus.
Both SF-series storage enclosures have the following features:
•

It can operate in one of two modes: through-bus or split-bus.

•

Each disk ISE has its own set of switches and indicators on the OCP.

•

The enclosure power supply provides operating power to all disk ISEs and
other subassemblies in the enclosure.

•

The drive dc power switches for the disk ISEs are on the front panel of the
storage enclosure.

Specifications for the SF3x series storage enclosure are shown in Table 1–3,
and Table 1–4 shows the specifications for the SF7x series storage enclosure.

DECarray Site Preparation
The DECarray cabinet is intended for installation in a Class A computer
room environment. Before installing the DECarray, make sure the following
conditions are met:
•

The DECarray cabinet requires 3-phase ac power. Each phase draws up to
7.2 amperes in a fully configured array.

•

Adequate space is provided around the DECarray cabinet for opening the
front and rear doors, for accessing cables, and for adequate airflow.

•

The installation site floor can safely bear the weight of the DECarray
cabinet. The DECarray cabinet with power controller weighs 180 kilograms
(396 pounds); a fully configured DECarray weighs 454 kilograms (1000
pounds).

•

The system’s configuration sheet has been correctly filled out and is
up-to-date. Blank system configuration sheets can be found in Appendix E.

•

An adequate number of DSSI adapter modules are installed in the system
to support all the DSSI devices in the DECarray.

•

The correct NEMA plug or plugs are available (Figure 2–1).

2–2 DECarray Site Preparation

DECarray Site Preparation

Proper grounding between the DECarray and any enclosures connected
through a common DSSI bus is required.
WARNING
If the enclosures are not connected to a common ground, there is a
potential for a personal safety hazard.

If the ground offset voltages generated in the power distribution system exceed
allowable limits, data transmission across the DSSI bus can be affected. In
this case, the system(s) could experience significant performance degradation
or possible data corruption.
For a DSSI installation, the maximum ground offset voltage differential
allowed between enclosures is as follows:
DSSI Bus Length1

Allowable Offset

Meters

Feet

Up to 20

Up to 65

200 mv

70 mv
(rms)

20-25

65-82

40 mv

14 mv
(rms)

1 The total length includes all DSSI cable lengths, internal and external to the enclosures.

Ensure that the power distribution systems meet local codes prior to DSSI
system installation. In a properly wired power distribution system(s) with
properly functioning equipment (no ground faults) connected to it, there
is generally no need for any further attention to grounding. The power
distribution system provides a satisfactory path between enclosures.
To make sure that this is the case, perform a power system survey before
installation. Check for the following conditions:
1. Do any outlets being used not have power ground connections?
2. Is the grounding prong missing on any of the computer equipment power
cords?
3. Are any of the power outlet neutral connections actually ground
connections?
4. Are the grounds for any of the power distribution circuits (outlets) not
connected to the same power distribution panel?

DECarray Site Preparation 2–3

DECarray Site Preparation

5. Are any devices that are not UL or IEC approved connected to the same
breaker as any of the DSSI computer equipment?
If the previous conditions do not exist, then the grounding should be adequate
for DSSI operation. Digital recommends that the ground offset voltage between
any two enclosures be measured. However, this only provides data for that
particular moment in time. Ground offset values may change as additional
devices are connected to the same power source.
If the installation exhibits ground offset voltages between interconnected
enclosures that exceed the allowable limits, use one of the following solutions:
1. Have an electrician correct any deficiencies detected during the power
system survey. This is the recommended solution.
2. Install grounding cables between enclosures. Grounding cables are
available from Digital, and come with the necessary hardware for
installation.
Installing additional grounding cables normally reduces the ground voltage
offset sufficiently to meet the requirements. In severe cases, however,
the cables may not be large enough. This is revealed by the ground
offset voltage measurements. If the additional grounding cables are not
adequate, the source of the ground offset voltage must be traced and either
reduced or eliminated.

3.1 Unpacking

3.1 Unpacking
The DECarray cabinet is packed in a cardboard carton attached to a wooden
shipping pallet and covered with plastic protection.
Note
Before unpacking the equipment, inspect the shipping carton for signs
of external damage. Report any damage to the local carrier and either
Digital Services or the sales office.

Note
Retain the shipping container and all packing materials.

CAUTION
Failure to stabilize the equipment thermally may damage the drive
media or associated electronics when the unit is powered up.
Remove the outer shipping carton, but leave the unit in place for at
least 24 hours (thermal stabilization time). Thermal stabilization
begins when the equipment is placed in the room where it is to be
installed.

WARNING
Adhere to electrostatic discharge (ESD) procedures at all times. Use
the ESD straps available with every array. The straps are inside the
front and rear doors.

Once the DECarray cabinet is unpacked, examine the front and rear doors,
the right and left side panels, and the undercarriage for any apparent damage.
Report any damage.

5.2 Where to Install the SF3x Storage Enclosure

5.2 Where to Install the SF3x Storage Enclosure
Storage enclosures must be installed in the DECarray cabinet in ascending
numerical order (see Figure 5–1). Storage enclosure positions are numbered
from 1 to 8 on the left and right chassis side rails. These numbers are visible
only when the front or rear doors of the DECarray cabinet are open.
SF3x storage enclosures can only occupy positions 1, 2, 3, 4, 7, and 8.
In split-bus mode the ISEs occupying the left-side slots share a DSSI bus, and
the ISEs occupying the right-side slots a different DSSI bus. This is true for
the front six ISEs and the rear six ISEs. Therefore, a fully-populated SF3x
enclosure in split-bus mode will have four DSSI buses, each with three ISEs
connected to it. Four DSSI adapter ports are required for each SF3x storage
enclosure.

Installing the SF3x Storage Enclosure in a DECarray Cabinet
5.5 Cabling the SF3x in the DECarray Cabinet

5.5.1 Through-Bus Configuration
Use the following procedures for cabling an SF3x storage enclosure in
a DECarray cabinet configured for single-system or DSSI VAXcluster
configurations in through-bus mode.
The following procedures assume that all devices installed previous to a new
installation of an SF3x storage enclosure are cabled in the single-system
configuration.
5.5.1.1 Identifying DSSI Connectors on the System I/O Panel
The following procedure explains how to locate and identify the DSSI
connections on the host system I/O panel.
Note
Before performing the following steps, refer to the system documentation for the correct procedure to perform an orderly shutdown of the
systems that the DECarray is connected to.

Note
This procedure assumes that no SF3x storage enclosures are installed
internally in the system cabinet. If SF3x storage enclosures are in the
system cabinet, then one of the KFMSA modules in the system XMI
backplane must be connected to those SF3x storage enclosures. Do
NOT use this KFMSA module or its DSSI connections to connect the
system to the DECarray. Do NOT count this KFMSA module in the
following steps.

Installing the SF7x Storage Enclosure in a
DECarray Cabinet
This chapter describes the add-on installation of the SF7x storage enclosure
into a DECarray cabinet. These procedures assume that the DECarray cabinet
previously has been correctly installed and configured.
The SF7x storage enclosure that you are installing may contain two or four
RF7x disk ISEs. To determine if the SF7x contains two or four ISEs, open the
front door of the DECarray cabinet and look at the front of the SF7x enclosure.
If both sides of the enclosure contain an ISE, then the enclosure contains
four ISEs (SF7x–JK variant). If there is an ISE on only one side of the SF7x
enclosure, then that enclosure contains only two ISEs (SF7x–HK variant).
The following procedures are described in this chapter:
•

Installing the SF7x Storage Enclosure (Section 6.1)

•

Cabling the SF7x (Section 6.6)
Single-system configuration (Section 6.6.1)
DSSI VAXcluster configuration (Section 6.6.2)
Stripeset configuration (Section 6.6.3)

•

Powering up the SF7x (Section 5.6)

•

Labeling the DSSI cables and OCP (Section 5.7)

•

Final verification (Section 6.9)

Only Digital Services or customer personnel that have been trained in ESD
procedures should perform the installation.

Installing the SF7x Storage Enclosure in a DECarray Cabinet 6–3

Installing the SF7x Storage Enclosure in a DECarray Cabinet
6.1 Installing the SF7x Storage Enclosure
When the DECarray will operate in a single-system configuration, the SF7x
enclosures in positions 1, 2, 4, and 7 operate in the through-bus mode. To
check if the SF7x enclosure is in through-bus mode, look at the lower of the
two LEDs on the OCP (labeled LED 2: SPLIT-BUS MODE). It should be off.
When the DECarray will operate in a DSSI VAXcluster configuration, all
enclosures must be configured in the through-bus mode.
Positions 3 and 8 operate in the split-bus mode and require you to reconfigure
their transition termination module (TTM). The procedure for doing this is
presented later in this chapter.
To check if the SF7x enclosure is in split-bus mode, look at the lower of the two
LEDs on the OCP (labeled LED 2: SPLIT-BUS MODE). It should be lit.

6.2 Unpacking the SF7x Storage Enclosure
Unpack the SF7x shipping container. The enclosure is shipped in an
environmental barrier bag with desiccant.
Note
After unpacking, retain the container and all packing materials.

6.3 Where to Install the SF7x Storage Enclosure

6.3 Where to Install the SF7x Storage Enclosure
Storage enclosures must be installed in the DECarray cabinet in ascending
numerical order. Storage enclosure positions are numbered from 1 to 8 on the
left and right chassis side rails. These numbers are visible only when the front
or rear doors of the DECarray cabinet are open.
SF7x storage enclosures can only occupy positions 1, 2, 3, 4, 7, and 8.
In split-bus mode, the following drives are part of the same DSSI bus (note
that split-bus mode is supported in the single-system configuration only):
1. Four drives in position 1 with the two left drives of position 3
2. Four drives in position 2 with the two right drives of position 3
3. Four drives in position 4 with the two left drives of position 8
4. Four drives in position 7 with the two right drives of position 8
Note
In a stripeset configuration, all SF7x storage enclosures must be in
split-bus mode. Each DSSI bus is connected to two ISEs in each SF7x
enclosure. Two DSSI adapter ports are required for each SF7x storage
enclosure.

All SF7x storage enclosures must be in through-bus mode when the DECarray
is in the DSSI VAXcluster configuration:
1. Four drives in position 1
2. Four drives in position 2
3. Four drives in position 3
4. Four drives in position 4
5. Four drives in position 7
6. Four drives in position 8

6.6 Cabling the SF7x in a DECarray Cabinet

6.6.1 Single-System Configuration
Use the following procedures for cabling an SF7x storage enclosure in a
DECarray configured for single-system.
The following procedures assume that all devices installed previous to a new
installation of an SF7x storage enclosure are cabled in the single-system
configuration.
6.6.1.1 Identifying DSSI Connectors on the System I/O Panel
The following procedure explains how to locate and identify the DSSI
connections on the host system I/O panel.
Note
Before performing the following steps, refer to the system documentation for the correct procedure to perform an orderly shutdown of the
systems that the DECarray is connected to.

Note
This procedure assumes that no storage enclosures are installed
internally in the system cabinet. If storage enclosures are in the
system cabinet, then one of the KFMSA modules in the system XMI
backplane must be connected to those storage enclosures. Do NOT use
this KFMSA module or its DSSI connections to connect the system to
the DECarray. Do NOT count this KFMSA module in the following
steps.

1. Open the system I/O panel on the system by removing the screws that
secure the I/O panel to the system chassis. Let the panel swing down to its
resting position.
2. Find the first KFMSA module installed in the XMI backplane of the
system. It is the KFMSA module in the lowest numbered slot of the XMI
backplane.
3. Follow the cabling from the backplane to the system I/O panel.
4. While viewing the front of the I/O panel, note that the DSSI connector
on the left is KFMSA DSSI bus 2 and the DSSI connector on the right is
KFMSA DSSI bus 1. These connectors should be labeled BLUE for bus 1
and RED for bus 2.

6–34 Installing the SF7x Storage Enclosure in a DECarray Cabinet

Installing the SF7x Storage Enclosure in a DECarray Cabinet
6.6 Cabling the SF7x in a DECarray Cabinet
5. Find the next KFMSA module installed in the XMI backplane of the
system. It is the next KFMSA module after the KFMSA module in the
lowest numbered slot of the XMI backplane.
6. Follow the cabling from the backplane to the system I/O panel.
7. While viewing the front of the I/O panel, note that the DSSI connector
on the left is KFMSA DSSI bus 2 and the DSSI connector on the right is
KFMSA DSSI bus 1. These connectors should be labeled YELLOW for bus
1 and GREEN for bus 2.
If these connectors are not labeled, label them now with the small colored
labels in the SF Family Label Booklet.
For the single-system configuration, use the BLUE, RED, YELLOW, and
GREEN labels only.
6.6.1.2 Cabling Position 1 or 2 with a Magazine Tape ISE
WARNING
Before performing the following steps, refer to the system documentation for the correct procedure to perform an orderly shutdown of the
system that the DECarray is connected to.

The following steps are for cabling a storage enclosure in position 1 with a
magazine tape ISE in position 5, or for cabling a storage enclosure in position
2 with a magazine tape ISE in position 6.
CAUTION
Use care not to disturb or damage power cords and DSSI cables that
are already connected to the DSSI I/O panel.

1. Tighten the shipping screw in the rear, upper right corner of the magazine
tape ISE.
2. Remove the DSSI terminator from the bottom DSSI connector on the rear

6.6.2 DSSI VAXcluster Configuration
Use the following procedures for cabling an SF7x storage enclosure in an
existing DECarray cabinet configured for DSSI VAXcluster systems.
The following procedures assume that all devices installed previous to a new
installation of an SF7x storage enclosure are cabled in the DSSI VAXcluster
configuration.
6.6.2.1 Identifying DSSI Connectors on the System I/O Panel
The following procedure explains how to locate and identify the DSSI
connections on the system I/O panel.
CAUTION
Before performing the following steps, refer to the system documentation for the correct procedure to perform an orderly shutdown of the
systems that the DECarray is connected to.

Note
This procedure assumes that no storage enclosures are installed
internally in the system cabinet. If there are storage enclosures
installed in the system cabinet, then one of the KFMSA modules
installed in the system XMI backplane must be connected to those
storage enclosures. Do NOT use this KFMSA module or its DSSI
connections to connect the system to the DECarray. Do NOT count this
KFMSA module in the following steps.

1. Open the system I/O panels on both systems by removing the screws that
secure the I/O panel to the system chassis. Let the panel swing down to its
rest position.
2. Find the first KFMSA module installed in the XMI backplane of each
system. It is the KFMSA module in the lowest numbered slot of the XMI
backplane.
3. Follow the cabling from the backplane to the system I/O panel.
4. While viewing the front of the I/O panel, note that the DSSI connector
on the left is KFMSA DSSI bus 2 and the DSSI connector on the right is
KFMSA DSSI bus 1. These connectors should be labeled BLUE for bus 1
and RED for bus 2.

8.5 Final Verification

8.5 Final Verification
Once the hardware installation, cabling and labeling, and the powering up
steps are complete, you are ready to configure the DSSI subsystem and verify
the correct operation of each ISE in the array with the host system.
Refer to the KFMSA Module Installation and User Manual for detailed
information on the correct operation of each ISE. These manuals contain
procedures for establishing the communications between the ISEs, the adapter
module, and the system. They also contain step-by-step procedures for
reconfiguring the system with its newly installed DSSI devices.
Refer to the manuals for the disk ISE and magazine tape ISE for detailed
information on the local programs in the ISEs.
If at any time you detect a failure, refer to Chapter 9.
Once the verification is complete, close the cabinet doors; turn the hex-Allen
fasteners one quarter turn clockwise to lock. The system is ready to be turned
over to the system manager.

Installation Troubleshooting
This chapter explains what to do if you detect problems with one or more
SF-series storage enclosure(s) during the installation of the DECarray cabinet.
The procedures in this chapter involve taking ISEs on- and off-line. This
causes a failure in the communications with the ISEs affected, resulting in
potential user problems. For this reason, the system manager should perform
an orderly shutdown of all DSSI ISEs before any troubleshooting. Refer to the
service or maintenance manuals for the affected ISEs.

Installation Troubleshooting 9–1

Installation Troubleshooting
9.1 Troubleshooting the Storage Enclosure

9.1 Troubleshooting the Storage Enclosure
This section presents symptoms of a failed device, the probable cause or causes
of the failure, and the action to take for correcting the failure. Much of the
corrective action calls for taking a device or devices off-line or for removing
power from the enclosure containing the failed device.
WARNING
Take all ESD and safety precautions when handling the devices, more
specifically, when taking a device off-line or when removing a device.
Failure to do so may damage the device.

Use the following basic steps for all troubleshooting that you perform for a disk
ISE in an SF-series storage enclosure, as it resides in a DECarray cabinet:
1. Inspect the ISE’s operator control panel (OCP). Is a Fault indicator lit? In
the case of an SF7x storage enclosure, press the Fault button and read the
error code.
2. Access the ISE in question. Gain access to the ISE’s various cables and
check that they are seated correctly.
3. Run DRVTST or DRVEXR on the ISE by using DUP.
4. According to the findings from the error codes and results from DUP, repair
or replace the ISE.
5. Run EVCXE or EVCXF configuration programs.
6. Verify the repair or replacement of the ISE with DRVTST and DRVEXR
under DUP.
7. Return the system to the user.

9.4 Bringing the RF Disk ISE On-Line

9.4 Bringing the RF Disk ISE On-Line
This section describes the procedure for bringing the ISEs in the storage
enclosure on-line.
1. Ensure that the DSSI node ID switches are set correctly, if applicable.
2. Place the ac power switch at the rear of the storage enclosure to the 1 (on)
position.
3. Press all drive dc power switches.
4. Press all Ready buttons on the OCP, one at a time.
5. If no Fault indicators are lit, then continue. If a Fault indicator is lit,
recycle the dc power once. If the failure appears again, refer to the
previous section.
6. Run the EVCXE or EVCXF programs to add the new disk ISE to the
configuration and to change any disk ISE internal parameters, if necessary.
7. Update the system configuration sheet.
8. Run DRVTST and DRVEXR (under DUP) to verify the correct operation of
the new disk ISEs.
9. Return the system to the user.

9.5 Troubleshooting the Magazine Tape ISE
Refer to the magazine tape ISE documentation for troubleshooting information.

A
DECarray Cabling Information
This appendix consists of tables containing cabling information for the
DECarray variations.

A.1 Single-System Configurations for DECarray with SF7x
Enclosures
Table A–1 contains cabling information for DECarray variations containing
SF7x enclosures in the single-system configuration.
Note the following:
•

DSSI bus termination is supplied by the TTM module inside the SF7x
storage enclosures in position 3 and 8.

•

The SF7x storage enclosures in positions 3 and 8 must be operating in
split-bus mode.

•

If a DSSI bus is not connected to a SF7x storage enclosure in position 3 or
8, then DSSI bus termination is accomplished by using a DSSI terminator
(PN 12–31281–01).

•

Split-bus mode is supported only in the single-system configuration.

A.3 Stripeset Configurations with SF7x Enclosures

A.3 Stripeset Configurations with SF7x Enclosures
Table A–3 contains cabling information for DECarray stripeset configurations
using SF7x enclosures.
Note the following:
•

The SF7x storage enclosures must be operating in split-bus mode.

•

DSSI bus termination is supplied by the TTM module inside the SF7x
storage enclosures.

•

If a DSSI bus is not connected to a SF7x storage enclosure, then DSSI bus
termination is accomplished by using a DSSI terminator (PN 12–31281–
01).

•

Stripesets are supported only in a single-system configuration.

Installing an SF3x-HK and SF7x-UK
Upgrade Kit
This appendix describes how to install the SF7x-UK and SF3x-UK upgrade
kits while the host system and the disk ISEs storage enclosure are off-line.
Refer to Section B.1 for instructions on how to take a disk ISE off-line.
To ensure the integrity of the host system, follow the steps in this procedure in
order and exactly as instructed.
Note
You must upgrade the two-drive SF7x-HK storage enclosure to contain
four drives before adding any other SF7x storage enclosures on that
bus of the DECarray.
Only one SF7x-HK storage enclosure can exist in a DECarray at one
time.

The following procedure assumes that the DECarray, and the SF7x storage
enclosures and magazine tape ISEs in the array, have been correctly installed
and configured.
Locate the system configuration sheet and ensure that it is filled out properly.
If the system configuration sheet reflects a configuration other than what is
recommended in this guide, you must maintain that particular configuration
throughout this procedure and work to ensure that no two devices on a DSSI
bus have the same DSSI ID number.
If this upgrade is to be followed by the installation of another SF7x storage
enclosure, a magazine tape ISE, or both, the host system must be brought
down according to the system documentation.

Converting a Single-System Configuration
to a DSSI VAXcluster Configuration
This appendix describes how to convert a DECarray, SF7x storage enclosure, or
magazine tape ISE that is configured according to single-system configuration
guidelines to DSSI VAXcluster configuration guidelines.
Note
This procedure is not necessary for DECarray cabinets using SF3x
storage enclosures. In this case, the DSSI VAXcluster configuration
only requires the addition of more than one host system to the already
existing DECarray configuration.

Ensure that you have the following before starting any procedure:
•

A #1 Phillips screwdriver (PN 29–11001–00)

•

A 1/8-inch hex key (PN 29–26115–00)

•

The KFMSA Module Installation and User Manual (EK–KFMSA–IM)

•

The SF Family Label Booklet (PN 36–32882–01)
Note
The host systems must be taken down to perform any of the steps in
this procedure, unless otherwise stated. Before cabling the DECarray
to the second host system, run the EVCXF configuration program
under VAX/DS and set the DSSI ID number of all KFMSA modules in
the second host system to 6. Refer to the KFMSA Module Installation
and User Manual for instructions on changing the KFMSA module
DSSI ID number.

Converting a Single-System Configuration to a DSSI VAXcluster Configuration C–5

Converting a Single-System Configuration to a DSSI VAXcluster Configuration
C.2 Conversion Procedure

C.2.1 Split-Bus to Through-Bus Conversion
Use the following steps only if you are converting an SF7x storage enclosure
in position 3 or 8 of an DECarray from single-system to DSSI VAXcluster
configuration. SF7x storage enclosures in position 3 and 8 must be converted
to through-bus mode.
CAUTION
Maintain ESD precautions at all times. Before performing the following
steps, locate the ESD strap in the ESD pouch at the bottom of the front
door.
To maintain stability, extend only one SF7x storage enclosure or
magazine tape ISE on the slide mounts at a time.

1. Remove the OCP by firmly grasping the right and left side of the OCP and
pulling the OCP straight off.
2. Loosen the four captive slide assembly screws. At the rear, push the inner
assembly out until the drawer locks in the service position.
Note
Do NOT completely remove the SF7x inner drawer assembly from the
extrusion tube.

3. Reconfigure the TTM for through-bus mode by first moving the small black
jumper to the through-bus terminals. Then move the cable connector from
J3 to J5, and the cable connector from J2 to J4 (Figure C–2).
4. Push the SF7x inner assembly back into the extrusion tube. To prevent
pinching any cables, be sure that all cables are dressed correctly.
5. Tighten the four captive slide assembly screws.
6. Set the DSSI ID number switches behind the OCP front door of positions 3
and 8 to match those in positions 1, 2, 4, and 7 (Table C–1).
7. Replace the OCP by lining up the taps on the back of the OCP with the
slots on the front of the storage enclosure. Firmly press the right and left
side of the OCP.

C.2 Conversion Procedure

C.2.2 Single-System to DSSI VAXcluster Cabling Conversion
Note
Ensure that both host systems and the DECarray are off-line and
powered down.

This procedure explains the steps to recable a DSSI bus configured for a
single-system application to a DSSI bus configured for a DSSI VAXcluster
application.
Figure C–3 shows the five possible single-system bus configurations.
Figure C–4 shows the three possible DSSI VAXcluster bus configurations.
The steps describe the conversion of each DSSI bus in the DECarray
individually. Follow each step for all DSSI buses present in the DECarray,
paying careful attention to all warnings, cautions, and notes.
The term DSSI bus n (where n = 1 to 6) refers to the DSSI buses used by the
host system, the DECarray, the SF7x storage enclosures, and the magazine
tape ISEs. In the single-system configuration, the four DSSI buses used are:
DSSI bus 1, color code blue
DSSI bus 2, color code red
DSSI bus 3, color code yellow
DSSI bus 4, color code green
In the DSSI VAXcluster configuration, the six DSSI buses used are:
DSSI bus 1, color code blue
DSSI bus 2, color code red
DSSI bus 3, color code yellow
DSSI bus 4, color code green
DSSI bus 5, color code blue with a white stripe
DSSI bus 6, color code red with a white stripe
Use Table C–2 to convert the existing DECarray from single-system configured
DSSI buses to the DSSI VAXcluster configuration and to Figures C–3 and C–4
for the actual bus configuration.

Installing a DECarray with a VAX 4000
System
This appendix describes how to install the DECarray correctly and safely with
VAX 4000 systems in two configurations:
•

Single-system installation (Section D.1) where one CK–SF200–LP cable kit
is required per DSSI bus.

•

DSSI VAXcluster installation (Section D.2) where two CK–SF200–LP cable
kits are required per DSSI bus.

Perform the steps in the appropriate section only after you have completed the
installation of the DECarray as described in previous chapters.
Ensure that all precautions for site preparation have been completed.
Digital Services or trained installers must perform the step described in the
following warning:
WARNING
Hazardous voltages are in the DECarray and in the components of the
DECarray.

Installing a DECarray with a VAX 4000 System D–1

Installing a DECarray with a VAX 4000 System
D.1 Single-System Installation of a DECarray

D.1 Single-System Installation of a DECarray
As many as four single-system configured VAX 4000 systems can connect with
a single DECarray.
The single DECarray requires connection to a DSSI adapter to support the
DSSI ISEs. The VAX 4000 Model 300 provides two embedded DSSI adapters
on the KA670 CPU module and also supports up to two KFQSA DSSI adapters
installed in the system Q-bus backplane. The VAX 4000 Model 200 provides
one embedded DSSI adapter on the KA660 CPU module and also supports up
to two KFQSA DSSI adapters installed in the system Q-bus backplane.
In a single-system configuration, up to seven ISEs and one adapter can be
supported on a single DSSI bus. That DSSI bus can consist of one tape ISE
and up to, six disk ISEs or up to seven disk ISEs (where one disk ISE is in the
system enclosure). For further information on single-system configurations,
refer to the customer hardware information kit.
Briefly, a fully configured single-system system could contain one of the
following:
•

Two TF857 magazine tape ISEs. 24 RF disk ISEs (in SF7x storage
enclosures) and no ISEs internal to the system enclosure.

•

One TF857 magazine tape ISE. 24 RF disk ISEs (in SF7x storage
enclosures) and one ISEs internal to the system enclosure.

•

24 RF disk ISEs (in SF7x storage enclosures) and two ISEs internal to the
system enclosure.

D.1.3 Single-System Final Verification
Once the hardware installation, cabling and labeling, and the powering up
steps are complete, you are ready to configure the DSSI subsystem and verify
the correct operation of each ISE in the array with the system.
Refer to the system installation manuals and TF857 Magazine Tape ISE
Service Manual for detailed information on the correct operation of each
ISE. These manuals contain procedures for establishing the communications
between the ISEs, the adapter module, and the system. They also contain
step-by-step procedures for reconfiguring the system with its newly installed
DSSI devices.
Refer to the manuals for the disk ISE and tape ISE for detailed information on
the local programs in the ISEs.
Remember, each SF7x storage enclosure can contain two or four disk ISEs.
Each TF857 magazine tape ISE contains one tape ISE. A fully configured
DECarray contains 24 disk ISEs and 2 tape ISEs.
If at any time you detect a failure, refer to Chapter 9.
Once the verification is complete, close the cabinet doors; turn the hex-Allen
fasteners one quarter turn clockwise to lock. The system is ready to be turned
over to the system manager.

D.2 DSSI VAXcluster Installation of a DECarray

D.2 DSSI VAXcluster Installation of a DECarray
As many as two pairs of DSSI VAXcluster configured VAX 4000 systems can be
used with a single DECarray.
A single DECarray requires connection to two DSSI adapters to support each
DSSI bus. The VAX 4000 Model 300 provides two embedded DSSI adapters on
the KA670 CPU module and also supports up to two KFQSA DSSI adapters
installed in the system Q-bus backplane. The VAX 4000 Model 200 provides
one embedded DSSI adapter on the KA660 CPU module and also supports up
to two KFQSA DSSI adapters installed in the system Q-bus backplane.
In a DSSI VAXcluster configuration, up to six ISEs and two adapters can be
supported on a single DSSI bus. That configuration can consist of one tape ISE
and up to five disk ISEs or six disk ISEs (where one disk ISE is in the system

D.2 DSSI VAXcluster Installation of a DECarray

Note
A DSSI VAXcluster bus can only be connected from a VAX 4000 to a
single DECarray and then to another VAX 4000.

For a VAX 4000 Model 200, DSSI bus 0 connects to ports 1 and 9 on the
DECarray. The first KFQSA adapter connects to port 2 and 10. The second
KFQSA adapter connects to port 3 and 11.
For a VAX 4000 Model 300, DSSI bus 0 and 1 connect to ports 1, 2 and 9, 10 on
the DECarray. The first KFQSA adapter connects to port 3 and 11. The second
KFQSA adapter connects to port 4 and 12.
This section provides the procedures for installing the DECarray in a DSSI
VAXcluster configuration correctly and safely. Digital Customer Services or
trained installing personnel must perform the procedures.
Ensure that all precautions for site preparation have been completed. Refer to
DECarray installation guide.
The following procedures describes how to:
•

Inspect the array for proper configuration (Section D.2.1)

•

Cable the DECarray with an existing VAX 4000 Model 300 system in the
DSSI VAXcluster configuration (Section D.2.2)

•

Check the DECarray for correct operation (Section D.2.3)

D.2 DSSI VAXcluster Installation of a DECarray

D.2.2 Cabling the DECarray (DSSI VAXcluster)
Start at the rear of the DECarray cabinet.
1. Plug the main power cable of the DECarray into its power receptacle.
WARNING
Hazardous voltages are in the DECarray and in the components of the
DECarray.
When performing any operation involving the power source, turn off
the power controls of all components and on the power controller.
Disconnect the power cable from the source outlet. Perform the
operation, then reconnect the power cable to the source.

2. Connect the 108–inch DSSI cable or cables (PN BC22Q–09) from the
DECarray DSSI I/O panel to the appropriate system DSSI connector.
a. At the system DSSI connector, remove the terminator or terminators
(part number 12–29258–01). See Figure D–9. Store these terminators
in the ESD pouch on the rear door of the DECarray cabinet.
b. The following is a list of system DSSI connectors (Figure D–9):
•

DSSI Bus 0 (embedded adapter, also connects to internal TF and
RF ISEs)

•

DSSI Bus 1, Model 300 only (embedded adapter, TF and RF ISEs)

•

KFQSA 1 (first installed adapter in the Q-bus backplane, RF ISEs
only)

•

KFQSA 2 (second installed adapter in the Q-bus backplane, RF
ISEs only)

Connect DSSI bus 0 of either DSSI VAXcluster system through the
DECarray and then to DSSI bus 1 on the other DSSI VAXcluster system.
This allows for the maximum number of embedded ISEs in a DSSI
VAXcluster configuration.
