Introduction
This chapter provides an overview of the SF200 storage array and the
SF72 storage enclosure, with specifications. A related documents list
provides references to supplemental information.

1.1 SF200 Storage Array Overview
The SF200 storage array is a storage rack cabinet designed to hold SF72
storage enclosures and magazine tape subsystems.
The SF200 storage array is intended to be installed on one or both sides
of a host system. All operator control panels (OCPs) project through the
front door of the storage array to allow easy access. The DSSI (Digital
Storage System Interconnect) 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.
A fully configured single-host SF200 storage array uses four DSSI buses.
A fully configured dual-host SF200 storage array uses six DSSI buses.
The remaining unused DSSI buses are for future use.
Viewing the SF200 storage array from the front, note that the SF72
storage enclosures and magazine tape subsystems are arranged in the
storage array as follows (Figure 1–1):
•

Levels 1, 2, and 4 are reserved for SF72 storage enclosures only.
SF72 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 subsystems. Magazine tape
subsystem upgrades are installed into this level in the following order:
position 5 then 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 SF200 storage array are shown in Table 1–1.

1.2 SF72 Storage Enclosure Overview
The SF72 is a storage enclosure (Figure 1–2) designed to be installed into
an SF200 storage array or certain system cabinets. A single enclosure
holds two or four RF72 disk integrated storage elements (ISEs). Each
disk ISE is independently controlled by the SF72 OCP. The power supply
in the enclosure provides the dc power and cooling for the disk ISEs.

SF72 Storage Enclosure

1–6 Introduction

The SF72 storage enclosure has the following features:
•

The SF72 storage enclosure can operate in one of two modes: throughbus or split-bus.
–

When in through-bus mode, all of the disk ISEs connect to a
single common DSSI bus inside the SF72 enclosure. The DSSI
bus is terminated by connecting to one of the following: a DSSI
terminator (part number 12–31281–01), another SF72 storage
enclosure operating in the split-bus mode (while in singlehost configuration), or another host system (while in dual-host
configuration).
Host configurations are explained later in this guide. Refer to the
KFMSA Module Installation and User Manual (EK–KFMSA–IM)
for a more detailed explanation.

–

When in split-bus mode, the disk ISEs on the left side of the
enclosure connect to a different DSSI bus than the disk ISEs on
the right side. Also, both DSSI buses terminate inside the SF72
on the transition termination module (TTM) behind the OCP. By
connecting one SF72 enclosure (operating in through-bus mode)
to an SF72 storage enclosure (operating in split-bus mode), two
DSSI buses with six disk ISEs each are obtained. This mode of
operation is used in single-host configurations only.

•

Each RF72 disk ISE has its own set of switches and indicators on the
OCP.

•

The enclosure power supply provides operating power to the
subassemblies of the enclosure. The rear panel of the power supply
contains the ac power switch for the SF72.

•

Two DSSI connectors are at the top rear of the enclosure. The DSSI
bus runs to each disk ISE in the enclosure.

•

The drive dc power switches for the disk ISEs are on the front panel
of the SF72 enclosure. Each switch contains a symbol to indicate its
associated disk ISE and an LED that lights when power is applied to
that disk ISE.

Specifications for the SF72 storage enclosure are shown in Table 1–2.

SF200 Storage Array Site Preparation
The SF200 storage array is intended for installation in a Class A
computer room environment. It must be operated in an environment
that meets the conditions specified in Table 1–1.
Before installing the SF200 storage array, make sure the following
conditions are met:
•

The SF200 storage array requires 3-phase ac power. Each phase
draws up to 6 amperes in a fully configured array, and produces 6400
Btu of heat per hour.

•

Adequate space is provided around the storage array for opening the
front and rear doors, for accessing cables at the rear of the storage
array, and for adequate airflow.

•

The installation site floor can safely bear the weight of the storage
array. (The SF200 storage array with power controller weighs 179.62
kilograms [396 pounds]; a fully configured storage array weighs
442.25 kilograms [975 pounds].)

•

The system’s configuration sheet has been correctly filled out and is
up-to-date. Blank system configuration sheets can be found in Figures
2–1 and 2–2.

•

An adequate number of KFMSA modules exist in the XMI backplane
of the VAX 6000 series system to support all the disk ISEs in the
SF200 storage array. Refer to the KFMSA Module Installation and
User Manual (EK–KFMSA–IM) for more details.

•

The correct NEMA plug or plugs are available (Figure 2–3).

Installing the SF72 Storage Enclosure in an SF200 Storage Array

5–3

5.1 Steps to Install
The following procedures assume that the existing SF200 storage array is
correctly installed and configured.
The SF72 storage enclosure that you are installing may contain two
or four RF72 disk ISEs. To determine if the SF72 contains two or four,
simply look at the front of the enclosure. Open the front door of the SF200
storage array. If you can see two disk ISEs in the front of the SF72, then
the enclosure contains four ISEs (SF72–JK variant). If you do not see
two ISEs in the front of the enclosure, then that enclosure contains only
two ISEs (SF72–HK variant). If you wish to verify an enclosure that is
already installed in a cabinet or array, observe the number of 7-segment
displays that are lit on the operator control panel (OCP). If the top two
displays are lit, then the enclosure contains only two RF72 disk ISEs.
This section contains several major parts. The first part explains the
steps to:
•

Unpack, inspect for damage, and identify parts

•

Determine where to install the SF72 enclosures

•

Read and fill out the system configuration sheet

The next part explains the steps to install the SF72 enclosure itself:
•

Prepare the array cabinet to receive an SF72 storage enclosure

•

Install the supporting hardware and SF72, and set the DSSI ID
switches

•

Cable the SF72 storage enclosure to comply with the DSSI bus cabling
conventions

Power up the SF72 enclosure, run the power-on self-test, and run the
configuration programs

•

Label all cables and operator control panels

•

Verify the operation of the enclosure after a successful installation

Follow all the steps in each of these parts in the order they are presented
and do not skip any steps.
When the array is to operate in a single-host configuration, remember
that the enclosure in positions 1, 2, 4, and 7 operates in the through-bus
mode. To ensure that the SF72 storage enclosure you are installing is
in the through-bus mode after the installation is complete, observe the
bottom indicator on the OCP. It should be off. Positions 3 and 8 operate
in the split-bus mode and require you to reconfigure their transition
termination module (TTM). That same indicator should be on once the
enclosure is set for split-bus mode. The procedure to accomplish this is
presented later in this chapter.
When the array is to operate in a dual-host configuration, remember that
all enclosures operate in the through-bus mode.

5.1.1 Unpacking the SF72 Storage Enclosure
Unpack the SF72 shipping container. The enclosure is shipped in an
environmental barrier bag with desiccant.
NOTE
After unpacking, retain the container and all packing materials.
At this time, examine the enclosure for physical damage. If you find
any damage, do not attempt to install the enclosure. Notify your office
immediately.
If there is no damage, then unpack all the boxes and bags, and identify
all the parts by using Table 5–2.

5.1.2 Where to Install the SF72 Storage Enclosure
The SF72 storage enclosures install in numerical order (Figure 5–1). For
your reference, the 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 SF200 storage array are open,
SF72 storage enclosures occupy positions 1, 2, 3, 4, 7, and 8 only.
In split-bus mode, the following drives are part of the same DSSI bus
(note that split-bus mode is supported in the single-host configuration):
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
All SF72 storage enclosures must be in through-bus mode when the
SF200 storage array is in the dual-host 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

Installing the SF72 Storage Enclosure in an SF200 Storage Array

5–11

5.1.4 Installation Procedure
Before attempting any of the following steps, ensure that the SF72
enclosures installed in the array cabinet contain four disk ISEs.
To determine if the SF72 contains two or four drives, simply look at the
front of the enclosure. If you can see two drives in the front of the SF72,
then the enclosure contains four drives (SF72–JK variant). If you do not
see two drives in the front of the enclosure, then that enclosure contains
only two drives (SF72–HK variant). If you wish to verify an enclosure
that is already installed and running in a cabinet or array cabinet,
observe the number of 7-segment displays that are lit on the operator
control panel (OCP). If the top two displays are lit, then the enclosure
contains only two RF72 disk ISEs.
The procedure for installing the upgrade kit is in Appendix B.
This section describes the step-by-step procedures for installing an SF72
storage enclosure in SF200 storage array positions 1, 2, 3, 4, 7, or 8.
Be sure to:
•

Follow each step in order, and do not skip any steps

•

Leave sufficient room to perform the installation (approximately 1.5
meters to 1.8 meters [5 feet to 6 feet] front and rear of the array)

CAUTION
Observe all ESD precautions and procedures.
An antistatic wrist strap is inside the front and rear doors.
CAUTION
Do not attempt to pick up or support the SF72 by the handle
in the rear of the enclosure. Doing so will injure the person
attempting the installation or damage the power supply.
To maintain stability, only one SF72 storage enclosure or
magazine tape subsystem should be extended on the slide mounts
at a time.

5–12 Installing the SF72 Storage Enclosure in an SF200 Storage Array

the center threaded hole of the slide mount.
e.

Install the opposite end of the slide mount into the rear cabinet
side rail. Again, align the guide pins with the X on the rail.

Install one 7/16-inch shoulder screw and washer (hand-tighten) in
the center threaded hole of the slide mount.

g. At the rear of the cabinet, install two 1/2-inch shoulder screws
with washers and the DSSI cable retainer clip. Note that the
DSSI cable retainer clip must always point away from the center
of the cabinet.
•

Place a 1/2-inch shoulder screw with a washer through the
upper hole of the DSSI cable retainer clip and install the
screw (hand-tighten) in the top threaded hole in the slide
mount.

•

Place the other 1/2-inch shoulder screw with a washer through
the lower hole of the DSSI cable retainer clip and install the
screw (hand-tighten) in the threaded hole in the slide mount.

Use the following procedures for cabling an SF72 storage enclosure in an
existing SF200 storage array configured for single-host.
The following procedures assume that all devices installed previous to a
new installation of an SF72 storage enclosure are cabled in the single-host
configuration.
5.2.1.1 Identifying DSSI Connectors on the System I/O Panel
The following procedure explains how to locate and identify the DSSI
connections on the VAX 6000 system I/O panel.
WARNING
Before performing the following steps, refer to the system
documentation for the correct steps to perform an orderly
shutdown of the systems that the SF200 storage array is
connected to.
NOTE
This procedure assumes that no SF72 storage enclosures are
installed internally in the system cabinet. If SF72 storage
enclosures are in the system cabinet, then one of the KFMSA
modules in the system XMI backplane must be connected to those
SF72 storage enclosures. DO NOT USE this KFMSA module or
its DSSI connections to connect the system to the SF200 storage
array. DO NOT COUNT this KFMSA module in the following steps.
1. Open the system I/O panel on the system by removing the six 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 the
system. It will be 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.
5. Find the next KFMSA module installed in the XMI backplane of the
system. It will be 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.

5.5 Final Verification
Now that all 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 (EK–KFMSA–
IM) and the TF837 Magazine Tape Subsystem Service Manual (EK–
TF837–SM) for detailed information and how to proceed with verifying the
correct operation of each ISE that has been installed. In these manuals,
you will find the procedure for establishing the communications between
the ISEs, the adapter module, and the system. You will also find the stepby-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 SF72 enclosure can contain two or four disk ISEs. Each
magazine tape subsystem contains one tape ISE. A fully configured
storage array contains 24 disk ISEs and 2 tape ISEs.
If at any time you detect a failure, refer to Chapter 7.
Once the verification is complete, close the cabinet doors; turn the hexAllen fasterners one quarter turn clockwise to lock. The system is ready
to be turned over to the system manager.

6.5 Final Verification
Now that all 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 (EK–KFMSA–
IM) and the TF837 Magazine Tape Subsystem Service Manual (EK–
TF837–SM) for detailed information and how to proceed with verifying the
correct operation of each ISE that has been installed. In these manuals,
you will find the procedure for establishing the communications between
the ISEs, the adapter module, and the system. You will also find the stepby-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 SF72 enclosure can contain two or four disk ISEs. Each
magazine tape subsystem contains one tape ISE. A fully configured SF200
storage array contains 24 disk ISEs and 2 tape ISEs.
If at any time you detect a failure, refer to Chapter 7.
Once the verification is complete, close the cabinet doors; turn the hexAllen 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 during the
installation of the SF72 storage enclosure.
The procedures in this chapter involve taking devices on- and off-line.
This causes a failure in the communications with the devices 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
device.

7–1

7–2 Installation Troubleshooting

7.1 Troubleshooting the SF72 Storage Enclosure
This section presents symptoms of a failed device, the probable cause or
causes of the failure, and the corrective action to take for correcting the
failure. Much of the corrective action calls either 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 will damage the device.
Use the following basic steps for all troubleshooting that you perform for
the RF72 disk ISE in an SF72 storage enclosure, as it resides in an SF200
storage array:
1. Inspect the ISE’s operator control panel (OCP). Is a Fault indicator
lit? If so, press the Fault button and read the error code.
2. Access the ISE in question. Open the front or rear of the SF72
enclosure and gain access to the ISE’s various cables and check that
they are seated correctly.
3. Run various tests 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 configuration programs, EVCXF configuration programs,
or both.
6. Verify the repair or replacement of the ISE with DRVTST and
DRVEXR under DUP.
7. Return the system to the user.

7.1.2 Bringing the RF72 Disk ISE On-Line
This section provides the procedure for bringing all the ISEs in the SF72
enclosure on-line and for setting DSSI ID numbers.
1. Ensure that the DSSI ID switches (behind the door on the OCP) are
set correctly. For positions 1, 2, 4, and 7, they are LR:1, RR:4, LF:2,
RF:3. For positions 3 and 8, they are LR:6, RR:6, LF:5, RF:5.
2. Place the ac power switch at the rear of the SF72 enclosure to the 1
or ON position.
3. Press all drive dc power switches.
4. Press all four Ready buttons on that 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
Section 7.1.1.
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.

7.2 Troubleshooting the Magazine Tape Subsystem
Refer to the magazine tape subsystem documentation for troubleshooting
information.

SF200 Storage Array Cabling Diagrams
This appendix contains cabling diagrams for the SF200 storage
array variations, in both the single-host (Section A.1) and dual-host
(Section A.2) configurations.
Table A–1 explains the nomenclature used in the cabling diagrams.
Table A–1 Cabling Diagram Key
T and B
R and L

Represent the top and bottom, right and left DSSI connectors
in the rear of the magazine tape subsystems and SF72 storage
enclosures.

TFx1
SFx2

TF is the designation for a magazine tape subsystem.
SF is the designation for a SF72 storage enclosure.
The x refers to the number of that unit.

Refers to the port number on the DSSI I/O panel.

Cables

Three DSSI cables are used:
BC21Q–3F = 42-inch (unit to unit)
BC21R–5L = 70-inch (SF200 I/O panel to unit)
BC21Q–09 = 108-inch (SF200 to system)

T at a DSSI connector stands for a DSSI terminator
(12–31281–01).

1 There are only two magazine tape subsystems per SF200 storage array.
2 There are up to six SF72 storage enclosures per SF200 storage array.

A.1 Single-Host Configuration
This section contains cabling diagrams for SF200 storage array variations
in the single-host configuration.
Note the following:
•

DSSI bus termination is supplied by the TTM module inside the SF72
storage enclosures in position 3 and 8.

•

The SF72 storage enclosures in positions 3 and 8 must be operating in
split-bus mode.

•

If a DSSI bus is not connected to a SF72 storage enclosure in position
3 or 8, then DSSI bus termination is accomplished by using a DSSI
terminator (part number 12–31281–01).

•

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

Installation Procedures for an SF72-UK
Upgrade Kit
B.1 Introduction
This procedure allows the SF72-UK upgrade to be performed while the
host system and the disk ISEs in the SF72-HK storage enclosure are
off-line. Refer to Section B.2 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 SF72-HK to contain four drives
before adding any other SF72 storage enclosures on that bus of
the SF200 storage array.
Only one SF72-HK SF72 storage enclosure can exist in an SF200
storage array at one time.

B–2 Installation Procedures for an SF72-UK Upgrade Kit

WARNING
The following procedure assumes that the SF200 storage array,
and the SF72 storage enclosures and magazine tape subsystems in
the array, have been correctly installed and configured according
to the standard bus and configuration guidelines in this guide.
Locate the system configuration sheet and ensure that it is filled
out.
•

At this point, the host system must be brought down to
continue.

•

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. Should this situation exist, Do not
attempt to use this procedure while the system is on-line.

NOTE
Make sure that no two ISEs have the same DSSI ID number.
If this upgrade is to be followed by the installation of another
SF72 storage enclosure, a magazine tape subsystem, or both,
the host system must be brought down according to the system
documentation.

C.2.4 Power up the SF200 Storage Array
Now that the SF200 storage array has been converted to dual-host and
labeled you are ready to apply power.
CAUTION
Ensure that the ac power switch on each SF72 storage enclosure
and magazine tape subsystem installed is in the off position.
1. At the rear of the storage array, turn the 881 power controller on.
Ensure that the BUS/OFF/ON switch is in the down position.
2. At the rear of the storage array, turn on each magazine tape
subsystem installed (if present). Power up position 5 and then 6.
Observe the front panels for any fault indications.
3. At the rear of the storage array, turn on each SF72 storage enclosure
starting with position 1 and following in numerical order.
4. Depress each drive dc power switch for each SF72 storage enclosure.
Start with position 1 and continue in numerical order.
5. Observe the OCP indicators. Refer to Figure C–9.
a. Check that the TERM PWR LED (located behind the door of the
OCP) is on for all positions installed.
b. Check that the SPLIT LED (located behind the door of the OCP)
is off for all positions.
c.

Ensure that all DSSI ID switches on all OCPs are set to left-rear
(ID=1), left-front (ID=2), right-front (ID=3), and right-rear (ID=4).

6. Depress the Ready button on the OCP. Refer to Figure C–9. The green
Ready LED will flicker then light steady once the ISE is on-line.

C.2.5 Bringing a Newly Converted Dual-Host Conversion
On-Line
Refer to the sections in the KFMSA Module Installation and User Manual
that deal with configuring a dual-host configuration.
Note that you will be instructed by these sections to perform the following
tasks:
•

Boot VAX/DS on the host systems.

•

Attach the KFMSA modules in each system.

•

Select each KFMSA module in each system.

•

Run EVCXE or EVCXF.

•

Modify certain parameters in the disk ISEs.

•

Ensure that all modified parameters are recorded as permanent
values.

•

Verify the communication path with all ISEs on the DSSI buses.

After all of the above have been accomplished successfully, return the
systems and the SF200 storage array to normal operating mode.

C–22 Converting a Single-Host Configuration to a Dual-Host Configuration

C.2.6 Final Verification
Now that the SF200 storage array has been converted, cabling and
labeling, and the powered up, 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 Guide, EK–KFMSA–
IM, TF837 Magazine Tape Subsystem Service and Installation Manual,
EK–TF837–IM, and the RF31/RF72 Intregrated Storage Element User
Guide, EK–RF72D–UG) for the detailed information and how to proceed
with verifying the correct operation of each ISE that has been installed.
In these manuals you will find the procedure for establishing the
communications between the ISEs, the adapter module, and the system.
You will also find the 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 of the local programs contained within the ISEs.
REMEMBER, each SF72 enclosure can contain 2 or 4 disk ISEs. Each
magazine tape subsystem contains one tape ISE. A fully configured
storage array contains 24 disk ISEs and 2 tape ISEs.

Glossary
ADAPTER

A module that connects one or more device controllers to the host bus and
hides many of the host bus requirements from the controller. The KFMSA
module is an XMI to DSSI bus adapter.
ALLOCATION CLASS

A numerical value assigned to the ISE to indicate which host(s) on a
cluster it will be served by.
BAD BLOCK

An address on a disk or tape that is determined by the device controller
to be bad and, therefore, in need of replacement.
BAD BLOCK REPLACEMENT

The procedure used to locate a replacement block, mark the bad block as
replaced, and move the data from the bad block to the replacement block.
BLOCK

The smallest data unit addressable on a disk. Also called a sector. In
DSSI ISEs, a block contains 512 bytes of customer data, EDC, ECC, flags,
and the block’s address header.
DEVICE NAME

A unique name given to each device by the VMS operating system. The
device name generally includes either the allocation class and MSCP unit
number assigned to the device (if the allocation class is not zero), or the
node name and MSCP unit number (if the allocation class is zero).
DMA

Direct memory access.
DRVTST

A local program resident on the ISE. It is a comprehensive hardware test
used to verify ISE operation.
