General Information
Thie chapter describes the KFQSA module and the enclosures into which
it can be installed.

1.1

KFQSA Module Overview

The KFQSA module is an adapter that allows Q-bus based host systems
like the MicroVAX system to communicate with Integrated Storage
Elements (ISEs) connected through the DSSI bus. ISEs are intelligent
storage peripherals such as disk and tape devices. In a DSSI single
host conifiguration, the KFQSA can connect up to seven ISEs to the host
compu‘er through the DSSI bus. In a DSSI VAXcluster configuration with
a dua’ host configuration two KFQSAs can connect up to six ISEs to the
two Losts through the DSSI bus. In a DSSI VAXcluster configuration with
a tiree host configuration and three KFQSAs, the DSSI bus can connect
up to five ISEs.
Each DSSI ISE has its own controller, which contains the intelligence and
logic necessary to control data transfers over the DSSI bus. The KFQSA
contains the addressing logic required to make a connection between the
host and a requested ISE on the DSSI bus.

The KFQSA module is supported by the following operating systems and
diagnostic utilities:

VMS Version 5.1 or later!

ULTRIX-32m Version 3.0 or later

VAXELN Version 3.0 or later

)'DM Version 3.0 or later

! KFQSA DSSI VAXcluster configurations must use VMS Version 5.1-1 or later.

BA440 System Enclosure

The BA440 pedestal enclosure (Figure 1-4) is used in VAX 4000 systems;
it is a free standing enclosure for use in an office environment.
Figure 1-4

BA440 Enclosure

MLO-004032

The BA440 enclosure has a 12-slot, quad-height backplane (Figure 1-5).
The backplane is a 21 x 16 inch assembly. The space between each
backplane slot varies. The backplane’s printed circuit board is an eightlayer, two-sided etch board.

From right to left, the first five backplane slots are for the MS670
memories and the KA670 CPU, while the other seven slots are Q-bus
or CD bus slots.

Modules installed in the BA400 and BA200 series enclosures that connect
to external devices have bulkhead handles with the I/O connector on the

handle. The handles replace the insert panels and internal cabling found
in other enclosures. This design is easier to maintain since it eliminates
problems caused by faulty internal cabling.

BA213 System Enclosure

The BA213 enclosure has a 12-slot, Q-bus backplane and two modular
power supplies. Figure 1-6 shows the BA213 enclosure.

The backplane implements the Q@-bus on the AB rows of each slot. The
CD interconnect is implemented in all slots. MicroVAX systems use the
CD rows of slots 1 through 5 for their high-speed memory interconnect.
Figure 1-6

Ceneral Information

Bus grant signals pass through each installed module through the A
connectors of each slot. Figure 1-7 shows the bus grant routing for the
BA213 backplane. Use bus grant continuity cards (M9047) in vacant
backplane slots {0 ensure bus continuity.
The BA213 enclosure holds up to four standard 5.25-inch storage devices.
Fixed disk drives face the rear of the enclosure, providing easy access
to the drive signal and power cables. Tape drives face the front of the
enclosure.

The major difference between the BA213 and other microsystem
enclosures is in the way you connect modules to external devices. Other

enclosures have an I/O panel in the rear of the enclosure. The BA213
uses bulkhead handles or covers that fit over the front of the module.
Standard modules have bulkhead handles that are an integral part of the
module. Option modules, such as the KFQSA, have a bulkhead cover that
performs the same function, but are not attached to the module.
The bulkhead handles and covers form an electrical seal that complies
with FCC regulations for keeping radio frequency interference (RFI)
generated by the system inside the enclosure, and for keeping externally
generated RFI out of the enclosure. They also help guarantee proper
airflow through the system for module cocling.

BA123 System Enclosure

The BA123 enclosure has a 13-slot, @-bus backplane and holds up to five
5.26-inch storage devices. Figure 1-8 shows the BA123 enclosure.

The first 12 slots are for dual or quad-height modules. The CD rows of
slot 13 are for the signal distribution board. If needed, a second signal
distribution board can be installed in the AB rows of slot 13.

The backplane implements the Q-bus modules on the AB rows of each
slot. MicroVAX systems use the CD rows of slots 1 through 4 for their
high-speed memory interconnects. Figure 1-9 shows the bus grant
continuity path for the BA123 backplane.
You can install the KFQSA and other Q-bus modules in slots 5 through
12. As a rule, if you install a dual-height module in either the AB rows or
the CD rows of & slot, you must install another dual-height module or a
bus grant continuity card in the other two rows of the slot. The exception
to this rule occurs when the dual-height module is installed in the last
occupied slot in the card cage.

Genera: Information

1-13

The backplane implements the Q-bus module on the AB rows of each
slot. The CD rows of slots 1 through 3 form the MicroVAX memory
interconnect. You should install only MS630 memory modules in the CD
mws of slots 2 and 3. You can install any dual-heignht modules in the AB
rows of slots 2 and 3. Slot 1 is reserved for the CPU module. Figure 1-11

shows the bus grant continuity path for the BA23 backplane.

You cax install the KFQSA and other Q-bus modules in slots 4 through
8. As a rule, if you install a dual-height module in either the AB rows or
the CD rows of a slot, you must install another dual-height module or a

bus grant continuity card in the other two rows of the slot. The exception
to this rule occurs when the dual-height module is installed in the last
occupied slot in the card cage.

DSSI VAXcluster Configurations

DSSI ISEs have a capability built into their firmware that allows the ISE
to maintain simultaneous connections with more than one host system.
A DSSI VAXcluster configuration uses DSSI cables as the interconnect.
Q-bus modules for VAX or MicroVAX systems interface to DSSI cables
by means of a DSSI adapter, such as a KFQSA module. Some adapter
modules are embedded in the processor module.

As many as 8 DSSI nodes may use the same interccnnect. A DSSI node
is any device {0 which DSSI transports information and for which DSSI
therefore needs an address, including ISEs and XFQSA modules on VAX
or MicroVAX systems.

In a DSSI VAXcluster configuration, the host systems (and possibly an
expansion cabinet such as the R215F) are connected together through
an external DSSI cable. Each system is a boot server in a Local Area
VAXcluster configuration. The host systems may share a common system
disk ISE or may have independent system disk ISEs. Each system has
direct and equal access to the common system disk ISE through its
KFQSA module, and to any other ISE in either enclosure.

Figure 1-12, Figure 1-13, and Figure 1-14 are examples of DSSI
VAX ~luster configurations using the KFQSA module.

The benefits of a KFQSA-based DSSI VAXcluster configurations are:
*

VAXcluster features, such as shared data across systems and satellite
nodes

Simplified system management due to .: shared system disk (see the

following page)

Shared batch and print queues

Higher system availability

General Information

1-15

NOTE
Systems that use the KFQSA module can only form DSSI
VAXcluster configurations with other KFQSA-based systems.
NOTE
DSSI VAXcluster configurations are only supportad under VMS
Version 8.1-1 and later, and only when the systems are configured
into the same Local Area VAXcluster configuration.
NOTE
Due to limitations in the Mic:oVAX II boot ROMs, two MicroVAX I
systeins in a DSSI VAXcluster configuration cannot automatically
boot from a common system disk ISE. If a common system disk is
used, each node in the DSSI VAXcluster configuration must boot
from a different root (SYS0, SYS1). But the MicroVAX Il system
can oiily boot automaticaliy from SYS0. It is recoinmended that
each MicroVAX II system have its own locally connected system
disk {such as an RD54 or RAS2). When a common system disk ISE
is a requirement, one MicroVAY II gystem may automatically boot

from SYSO0 but the other must oe booted manually from SYS]1.
When a MicroVAX 71 system is clustered (DSSI VAXcluster

configuration) with a MicroVAX 300 series system, the MicroVAX I
system sheuld booi from SYS0 and the MicroVAX 300 series system
should boot from an alternate root.

Planning the System Installation

It is important to carefully plan the system installation before putting any
new modules into the system. This involves checking the power and bus
load requirements, and checking to make sure you have everything yoa
need to make the configuration work.
Fill out a configuration worksheet before proceeding with the installation
A configuration worksheet lets you track the parameters that limit system
configuration such as space, power requirements, and bus loads.
Figure 3-1, Figure 3-2, Figure 3-3, and Figure 3—4 are examples of

a configuration worksheets for the BA440, BA213, BA123, and BA23
enclosures, respectively. Table 3—1 lists power and bus load data for all
currently supported modules and storage devices

Complete the configuration worksheet by performing the following steps:
1.

List all devices already installed in the system.

List all devices you plan to install in the system.

Fill in the power and bus load data from Table 3-1 for each device you
have listed.

Add the columns and make sure the totals are within the hmits

specified for the enclosure.

KFQSA Switches
Before installing the KFQSA, you must choose a control and status
register address (CSR) that will allow the host to access the adapter. A
four-position DIP switchpack is provided for this purpose. Figure 4-1
shows the location of the switchpack. Table 4-1 explains the function of
each switch.

In most cases you should use one of the dedicated CSR addresses, as this
allows a programming address to be selected without the possibility of
conflict with other modules in the system. To do this. set the switches as
follows:

Switch 1—ON

Switch 2—OFF

KFQSA Switch Settings

Switch

Position

Function

OFF

With Switch 1 in the OFF position (toward the number 1,,
the other switches are ignored and CSR addresses are read
from the configuration table. After the configuration table
has been programmed (Chapter 7), the system should be
powered down and this switch should be set to the OFF
position, where it should remain unless the configuration
table is corrupted and needs to be reprogrammed.

Putting Switch 1 in the ON position enables the selection
of a CSR address for programming the configuration table.
This is the switch pesition for the initial installation. The
CSR address selected for programming depends on the
position of the other three switches.

OFF

Putting Switch 2 in the OFF position enables the selection
of one of four CSR addresses that have been dedicated

for programming the KFQSA. Table 4-2 shows how the

remaining two switchee are used to select one of these
addresses. These addreases should be used only for initially
accessing the KFQSA to program the EEROM.
ON

Putting Switch 2 in the ON position enables the selection

of one of four addresses normally reserved for MSCP or
TMSCP devices. Table 4-3 shows how the remaining two

switches are used to select one of these addresses.’

3and 4

When Switches 1 and 2 are ON and OFF, respectively,
these switches are used to select one of four dedicated CSR
addresses (Table 4-2).
When Switches 1 and 2 are both ON, these switches are
used to select either a disk (MSCP) address or a tape
(TMSCP) address (Table 4-3).

1Avoid using these addresses at this time; thev may conflict with other modules in the

aystem. They are provided for future use.

installation Procedures
This chapter explains how to install the KFQSA module into a host
enclosure.
CAUTION
Only qualified Digital Service personnel should attempt to install
the KFQSA module. Before starting the procedure, make sure
that the system manager has backed up all files. Have the system

manager perform a system shutdown of the operating system
before turning off power. idake sure the customer has taken these
steps before removing any panels from the enclosure.

CAUTION
Static electricity can damage integrated circuits. Always wear a
grounded wrist strap and use a grounded work surface, such as
the one found in the: Antistatic Kit (PN 29-26246) when installing
modules.
Before beginning the KFQSA module installation, the system should be
tested to verify that it is working correctly. The following procedure is
recommended, but may be altered due to on-site circumstances at the
discretion of the installer
1.

Have the system manager halt the operating system.

CAUTION
Ensure that 2ll necessary system software is backed up at this
time.
2.

Initiate the system power-on self-test (POST), and venfy that
these run successfully. Refer to your system documentation for the
appropriate procedures.

5-1

5-2

Installation Procedures

Boot the appropriate diagnostic monitor, and perform a complete
system level diagnostic test. Verify that these run successfully.

Once the previous tests have run successfully, power down the system
and proceed to the appropriate section for KFQSA module installation
procedures.

5.1

BAA440 Installation Procedure Using the
KFQSA-SG Option Kit

To gain access to the BA440 enclosure, there is a three-position lock
that determines which controls you can access. The level of access is as
follows:

Top position opens the upper door only.

Middle position locks both doors.

Bottom position opens both doors together.

To install the KFQSA adapter module, do the following:
1.

Insert the key into the lock on the front door. Turn the key to the
bottom position.

Installing DSSI VAXcluster Configurations

A DSSI VAXcluster configuration is a highly integrated organization
of VAX computers. As members of a DSSI VAXcluster, computers can
share processing resources, disks and queues under single VMS security
and management software, and can boot and fail independently. DSSI
VAXcluster configurations provide a high level of processing and data
access.

5.5.1 Types of DSSI Bus Configurations
DSSI Single Host Conflguration uses DSSI bus as the interconnect.
Q-bus or MicroVAX systems interface to a DSSI bus by means of a
DSSI adapter (KFQSA). As many as 8 DSSI nodes may use the same
interconnect. A DSSI node is any device to which DSSI transports
information, and therefore needs an address. In a DSSI single host
configuration, the node number for the KFQSA is usually 7.
Two-System DSSI VAXcluster configurations use two host systems

to share RF-series ISEs. The maximum number of ISEs that can be
accessed by the hosts is 6. The ISEs can be located within each host,
within an expander enclosure, or both. A two-ho:t system provides
high disk availability for critical applications. In a two-system DSSI
VAXcluster configuration, the node numbers for the I{F'QSAs are 7 and 6.
Three-System DSSI VAXcluster configurations allow the common DSSI
bus ¢o share all the resources among the three hosts. In a three host
configuration, the middle node (KFQSA6), all the internal terminators are
removed from the board (Figure 4-1). The unterminated KFQSA adapter
has both an IN and OUT bulkhead connector that allows DSSI bus signals
to travel through the adapter to the other hosts. The maximum number
of ISEs to be accessed in this configuration is 5.

5-18

Installation Procedures

5.6

Rules for Installing DSSI VAXcluster Systems

There are some restrictions that apply to DSSI VAXcluster systems using
the KFQSA module:

Adapter modules connected to the same DSSI bus when running VMS

The host systems must be in close proximity to each other, due to
DSSI bus cable length limitations (measured from end terminator

Version 5.3-1 and earlier must be of the same type.

to end terminator). The maximum distance in a three-system
configuration is 82 feet in a computer room environment and 656

feet in an office environment.

All enclosures in a DSSI VAXcluster configuration must be powered
from the same ac feed. That is, they must either be powered from
the same ac circuit, or if they are powered from different ac circuits,
then those circuits must not power any other equipment, must share a
single ground point, and must have a dedicated ground wire between
the outlet and the single point ground.

Terminators must reside at the ends of the DSSI bus when configured

All systems must be using VMS Version 5.1-1 or later.

The maximum of 5 enclosures can be configured on a DSSI
VAXcluster; for example, two VAX or MicroVAX systems and three
expansion enclosures or three VAX systems and two expansion
enclosures.

Each ISE on a DSSI VAXcluster configuration must appear with the
same device name and address on all host nodes.

A maximum of 3 Q-bus VAX or MicroVAX systems can be present on

for multiple hosts.

a DSSI VAXcluster configuration. The middle KFQSA adapter board

is unterminated.

Each node on a single DSSI interconnect must have a unique DSSI ID
number, which allows the software to communicate with the storage
devices. Numbers must be between 0 and 7; these numbers are
permanently associated with the hardware. Node numbers may be
repeated on different DSSI interconnects that are connected to the
same host systems.

installation Procedures

5-19

The length of any single cable between the connectors on DSSI

VAXcluster buses is 25 feet.

NOTE
Due to limitations in the MicroVAX II boot ROMs, two MicroVAX I

systems in a DSSI VAXcluster configuration cannot automaticaily
boot from a common system disk ISE. If a common system disk is

used, each node in the DSSI VAXcluster configuration must boot

from a different root (8YS0, SYS1). But the MicroVAX Il system
can only boot automstically from SYS0. It is recommended that
each MicroVAX Il system have its own locally connected system
diek (such as an RD54 or RA82). When a common system disk ISE
is a requirement, one MicroVAX II system may automatically boot
from SYSO0 but the other must be booted manually from SYS]1.
When a MicroVAX Il system is in a DSSI VAXcluster configuration
with a MicroVAX 3000 or higher series system, the MicroVAX II
system should boot from SYS0 and the MicroVAX 3000 or higher
series system should boot from an alternate root.
If you are insgtalling more than one system into a DSSI VAXcluster
configuration, install each system individually and test it to make sure it
is working correctly. When you complete the installation and testing of
each system, then reconfigure each system using the procedures in either
Chapter 6 or Chapter 7.

This includes:
¢

Determining correct CSR addresses for all modules in each system

Reprogramming the KFQSA configuration table for the new
configuration

Reconfiguring any modules whose CSR addresses changed as a result
of the new configuration

Changing the allocation class of the ISEs so they are the same as both
hosts

After reconfiguring, remove the terminators and connect the DSSI
extension cables between the hosts or expansion cabinets.

Programming the DSSI Subsystem Using
Console Commands
The KFQSA configuration table may be programmed in two ways, either
by using console commands or by using the MicroVAX Diagnostic Monitor
(MDM). Using the console commands is the recommended choice if your
system has this capability.

To find out if you can use console commands for programming the
configuration table, reinitialize the system and read the microcode
version that is displayed on the console. If the microcode version is
4.1 or later, the console commands may be used for programming the
KFQSA configuration table.

If your system does not have this capability, refer to Chapter 7 for the
MDM procedure. If your system does have console commands, perform
the procedure described in this chapter.
To find the console commands available, type HELP at the consoie prompt
(>>>). To program the KFQSA configuration table, use these commands.

6.1

Determining CSR Addresses

Each module in a Q@-bus based syetem must use a set of unique Q-bus
address2s and interrupt vectors. One of these, generally the lowest of
the set, is known as the CSR address. The KFQSA emulates an SSP

controller! for each ISE connected, and presents a separate CSR address
for each emulated controller. You must program the KFQSA with a
correctly chosen CSR address for every ISE on the DSSI bus. Interrupt

1 SSP controllers also include the RQDX3, KDAS0, RRD50, RQC25, TQKS50, and
TQK70 controllers. All such ports are identical, and are operated by the same
PUDRIVER.

6~1

6-2

Programming the DSSI Subsystem Using Console Commands

vectors for the KFQSA (and other SSP controllers) are programmed
automatically by the operating system.
Unlike most other @--bus controllers, KFQSA CSR addresses are not set
with switches or jumpers. They are contained in nonvolatile memory on
the KFFQSA module in the form of a configuration table. To access the
configuration table, you must set the switches on the KFQSA to select
one of the dedicated addresses shown in Table 4-2. You must ensure the
KFQSA is terminated either through on-board SIP terminators or through
external DSSI terminators.
Before programming the configuration table, first determine what the
CSR addresses should be for all devices on the system. Calculating CSR
addresses is a complex procedure because some devices are assigned
floating addresses. Floating addresses vary with each module installed on
the system.

At the console prompt (>>>), type CONFIGURE.

The CONFIGURE console command is similar to the VMS SYSGEN
CONFIGURE utility. It permits the user to enter @-bus device names,
and then generates a table of recommended Q-bus CSR addresses.
After entering the command, the system prompts you {or a device and
a number. To find which responses are valid, type HELP. The system
displays:

Type EXIT. The Configure utility displays address/vector
assignments for all devices entered.

Compare the addresses displayed from running the Configure utility
with those displayed from the SHOW QBUS display.
Adding the ISEs from the remaining systems in the DSSI VAXcluster
configuration may bump the address of another Q-bus device. Make
sure that all device addresses, other than those of the ISEs, have not
changed. If the device address differs between the two displays, you
must reconfigure your system.

Programming the DSSI Subsystem Using Console Commands

Program the KFQSA configuration table in System A by following
the procedures outlined in Section 6.2. Make sure to include all ISEs
connected to the DSSI bus in the configuration table. Assign a DSSI
node ID of 7 to this KFQSA.

Repeat Steps 1 through 4 for System B, and if applicable for System
C.

Program the KFQSA in System B and C by following the procedures
outlined in Section 6.2. Make sure to include all ISEs in all systems
in the configuration table. Assign a DSSI node ID of 6 to the KFQSA
in System B, and 5 to the KFQSA in System C.
Power down all systems.

Remove the KFQSA modules from all systems, and set Switch 1 to the
OFF position.

Connect the DSSI cable between all systems.
10. Replace any necessary DSSI unit ID plugs in the Operator Control

Panels of each system to make them match the DSSI node IDs
assigned to the ISEs for the DSSI VAXcluster configuration.

NOTE
Make sure all DSSI ID sockets in all Operator Control Panels
have plugs in them. Use blank plugs in any sockets that do not
have corresponding ISEs connected.

CAUTION

Make sure that the device name of each ISE is identical on all
nodes. Failure to do so can result in a partitioned cluster, and
consequently data corruption.

6.4

Setting the ISE Allocation Class

This section describes how to change the ISE allocation class. In a DSSI
VAXcluster configuration, you must assign the same nonzero allocation
class to both host systems and all connected ISEs. The ISEs are shipped
with the allocation class set to zero.

Change the allocation class by using the following procedure.

Determine the correct allocation class according to the rules on

clustering.

NOTE

In a DSSI VAXcluster configuration, the same allocation class
must be assigned to both systems and to all connected ISEs.
This allocation class must be different from that of other
systems or HSC controllers in a cluster.

Configuring the DSSI Subsystem Using
MDM Commands
This cha . discusses how to assign CSR addresses as a preparation for
programming the KFQSA configuration table.

7.1

Determining CSR Addresses

Each module in a Q-bus based system must use a set of unique Q-bus
addresses and interrupt vectors. One of these, generally the lowest of the
set, i8 known as the CSR address.

7.1.1

QOverview

The KFQSA emulates an SSP controller! for each connected ISE.

Therefore, you must program the KFQSA with a correctly chosen
CSR address for every ISE on the DSSI bus. Interrupt vectors for the
KFQSA (and other SSP controllers) are programmed automatically by the
operating system.

Unlike most other Q-bus controllers, Ki'QSA CSR addresses are not set
with switches or jumpers. They are contained in nonvolatile memory on
the KFQSA module in the form of a configuration table The configuration
table is programmed using an MDM program, as explained in Section 7.2.
NOTE
KFQSA modules installed in MicroVAX 3000 and 4000 series
systems are more easily configured using the procedures given
in Chapter 6.

! SSP controllers also include the RQDX3, KDA50, RRD50, RQC25, TQK50, and

TQK70. All such ports are identical and are operated by the same PUDRIVER.

7-1

7-2

Configuring the DSSI Subsystem Using MDM Commands

NOTE

To access the configuration table you must set the switches on
the KFFQSA to select one of the dedicated addresses shown in
Table 4-2.

Before you program the configuration table you must first determine
what the CSR addresses are going to be for all devices on the system.
Calculating CSR addresses is a complex procedur: because some devices
are assigned floating addresses. Floating addresses vary depending on
which modules are installed on the system.

Use an MDM utility called IOADDRES to determine what the CSR
addresses and interrupt vectors should be for all devices on the system.
This utility is supported in MDM Version 3.0, Release 125 or later. The
next section describes hew to use IOADDRES. You should already have a
working knowledge of MDM. If you need detailed information on how to
use MDM refer to the MDM User’s Guide (AA-FM7A-DM).

7.1.2 Using MDM to Determine CSR Addresses
1.

Boot MDM.

Enter the correct date and time.

Select the command line mode (Opticn 2). The system issues a caution
and instructs you to enter 1 for the menu mode or 2 to proceed with
the command line mode.

Enter 2 and press [Retun] The system displays the MDM>> prompt.

Type the command Run IOADDRES. The system: responds with:
Configuring

utility

for

IOADDRES

The display prompts you to enter a number for each class of devices it
supports. Table 7—1 shows the abbreviations for supported devices.
6.

At each query, enter the number of devices from that class that are
installed in the system. If no devices of that class are installed in the
gystem, press [Rsturn| (the default value of zero is entered)

After you have responded to all queries, the system displays a
summary of the classes and the number of devices in each class.
It then displays a table containing the following information.

note of it) for programming the configuration table.

Type EXIT and presr [Return].

Once the CSR values are determined for all modules in the svatem. the
addresses for the DSSI devices must be programmed into the KFQSA
configuration table using the procedure detailed in the next section. If
any other modules in the system require reconfiguration. refer to the
installation manual for that module, or to your system maintenance
documentation for the configuration instructions.

NOTE
Removing a device to the KFQSA configuration table may change
the CSR address of other devices in the Q-bus floating address
space.

When taking a DSSI device off the bus, you need to clear the information
in the configuration table for that device. As an example, let us remove
the ISE we added in Section 7.2.2.

7.3

Programming the KFQSA for a DSSI VAXcluster
Configuration

This section describes how to program the KFQSA modules in a DSSI
VAXcluster.
NOTE
In a DSS]I VAXcluster environment, a three-system configuration’s
maximum length of cable(s) (measured from the two end KFQSAs)
is 82 feet in a computer room environment and 65 feet in an office
environment.
The maximum number of enclosures in a DSSI VAXcluster
configuration is 5. For example, two VAX or MicroVAX systems
and three expansion enclosures.

Figure 7-1 is a diagram of a typical two-system DSSI VAXcluster
application, which will be used as an example during this procedure.
NOTE

The DSSI cable(s) should be connected between the two
systems, and power to both systems should be turned on before
programming.
Perform the following procedure on System A:
1.

Determine the correct CSR address for each device and module in the
system by performing the steps outlined in Section 7.1.2. Make sure
to include all devices residing in the system and all ISEs connected to
the DSSI bus.

Program the KFQSA configuration table to add the CSR addresses,
DSSI node ID, and model number for the ISEs, as detailed in
Section 7.2.
NOTE
Make sure all DSSI node IDs programmed into the
configuration table are sequential and in increasing order.
Do not skip any numbers.

Reprogram any modules whose CSR addresses were bumped as a
result of including the ISEs.

Assign a DSSI node ID of7 to the KFQSA in System A.

Repeat the pr
ure in Steps 1 through 3 for System B Assign a
DSSI node ID of 6 to the KFQSA in this system.

NOTE
Make sure that the ISEs have been assigned the same DSSI

node IDs in both KFQSA configuration tables.

Configuring the DSS| Subsystem Using MDM Commands

7-17

CAUTION

Make sure that the device name of each ISE is identical on
both nodes. Failure to do so can result in a partitioned cluster,
and censequently data corruption.

Replace any necess ry DSSI unit ID plugs in the Operator Control
Panel for each ISE to make them match the DSSI node IDs assigned
to the ISEs for a DSSI VAXcluster configuration.

Boot one node and note the device names reported by VMS software.

Shut down the node and boot the other one. Note the device names to
ascertain that both systems see the same set of device names.

7.4

Setting the ISE Allocation Class

This section describes how to change the ISE allocation class. In a DSSI
VAXcluster configuration, you must assign the same nonzero allocation
class to all host systems and to all ISEs on the DSSI bus.
NOTE

DSSI ISEs are shipped with the allocation class set to zero.

Change the allocation class by using the following procedure. This
procedure only needs to be performed from one of the host systems.
1.

Determine the correct allocation class for the ISEs according to the
rules on clustering.
NOTE
In a DSSI VAXcluster configuration, the same allocation class
must be assigned to all systems and to all connected ISEs. This
allocation class must be different from that of other systems or
HSC in a cluster.

Diagnostics

This chaj ter describes the diagnostics for testing the KFQSA module and
the conne« ted DSSI ISKs.

8.1

Power-On Self-Test Diagnostics

The KFQSA module has a power-on self-test (POST) that performs a
comprehensive set of logic Lests whenever power is applied to the module,
or when the host issues a Q-bus BUS INIT. POST tests about 95 percent
of the KFQSA module's logic and executes in less than ten seconds. It
executes whether or not any other DSSI devices are connected to the
KFQSA module.
The KFQSA module has one green and five red LEDs mounted on the

edge of the board (Figure 8-1). When power is applied, all five LEDs
light. The red LEDs go out as POST routines are executed successfully.
After the successful completion of all POST routines only the green LED
remains lit.
NOTE
In some cases, the red LEDs go out so quickly that you may think
they never came on. If the green LED is on when you look at the
module after applying power, POST ran successfully.

8-2

Diagnostics

8.2

LED Error Codes

The two types of errors detected by POST are fatal errors and nonfatal
errors. Fatal errors cause the adapter to abort service and wait for
reinitialization. Nonfatal errors are recoverable.

A POST failure also causes an error code to be sent to the SA registers.
When the error is fatal, the microprocessors are forced into an infinite

loop sequence that can only be broken by receiving an INIT from the host.
If a nonfatal error i detected, the green LED remains lit and the red
LEDs display an error code for approximately ten seconds. Table 8-1
shows the POST LED nonfatal error codes.

If a fatal error is detected, the green LED goes out and a sequence of red
LEDs remains lit. Table 8-2 shows the POST LED fatal error codes.

Using MDM to Run NAKFA Diagnostics

NAKFA is a KFQSA functional diagnostic that is executed using the

MicroVAX Diagnostic Monitor (MDM) utility. The MDM utility scans for
individual devices on the bus, and loads one image of NAKFA for each
device it sees on the DSSI bus. Like all MDM diagnostics, NAKFA is
menu driven.
NOTE

This section is written for users with a working knowledge of the
MDM utility.

8.3.1

Loading NAKFA

There are several! ways to load and execute MDM diagnostics. This
section describes one way in which only the device being tested is selected.
This allows more time for KFQSA module or DSSI device trouhleshooting.

Utility

The KFQSA configuration utility is used to program the KFQSA
configuration table, as described in Chapter 6.
You can use this utility to install DSSI add-on devices if at least one
DSSI device is attached and has a valid address in the configuration
table, and the KFQSA mc-ule is in its normal operating mode (that is,
Switch 1 on the KFQSA module is set to the OFF position). However,
if the configuration table is corrupted, you must set Switch 1 to the
ON position, reboot the KFQSA module, and reconfigure EEROM
using this utility.

KFQSA Troubleshooting
The tools used to diagnose the KFQSA modute and connected ISEs are:
e

POST, power-on self test, described in Section 8.1.

NAKFA, KFQSA module'’s functional diagnostic, described in
Section 8.3 or the SET HOST/DUP console command described in
Section 8.4.

Generally, KFQSA module failures fall into one of two categories:
°

The system fails to boot because of a KFQSA module problem.

The system boots, but the KFQSA module fails.

In the case of a boot failure, verify the installation again using the

procedures outlined in Chapter 5. Then verify the configuration using the
procedures outlined in Chapter 6 or Chapter 7. Most boot problems are
caused by incorrectly setting up the device configuration or addressing.
If the system boots but the KFQSA module fails, reapply power to cause
POST to run, and cireck for the presence of a LED error code.

Always perform a visual inspection of the KFQSA module and all
connected DSSI devices before troubleshooting. Some KFQSA module
problems that can be solved by visual inspection are listed in Table 9-1.
