- HELP
The Level 3 Exerciser for RUX50 (EVRNB) is a "parallel" diagnostic
designed to verify the integrity of one or several drives under test,
and to detect faults at the functional level only. Under the Multi-
drive Subtest, the program should give a clear indication as to how
an RUX50 controller will perform under stressful operating system
conditions.
The Multidrive Subtest simulates these conditions by issuing a heavy
load of MSCP I/O commands to all online units. The user can control
many of the I/O command parameters through the Manual Intervention
Test (/SEC:MANUAL) including function (write-only, read-only, writes
and reads, write-compares, read-compares), disk block selection
(random vs. sequential), track number limits, and the selection of
data patterns.
- DEVICES
EVRNB supports the following devices:
Device type Device name
----------- -----------
RUX50 - disc controller DUa
RX50 - disk drive DUan
RX31 - disk drive DUan
RX32 - disk drive DUan
RX180 - disk drive DUan
- ATTACH
The ATTACH command is used for specifying descriptions of devices
existing on the system under test. A device cannot be accessed by
a diagnostic program unless it has first been attached. Attaching
a device generally consists of issuing a set of ATTACH commands so
that a series of links can be established from the processor to the
device. The link that is closest to the processor is a
pseudo-connection known as "HUB". All devices must be ultimately
linked to HUB. The format of the ATTACH command is as follows:
ATTACH dev-type dev-link generic-name [device-specific-info]
In order for EVRNB to exercise RUX50 and its drives, the following
ATTACHes must be made:
UBA (UNIBUS adapter) - must be ATTACHed to the HUB
RUX50 (disk controller) - must be ATTACHed to the UBA
disks* (removable disks) - must be ATTACHed to the RUX50
* disks can be any combination of from 1 to 4
RX50s, RX31s, RX32s and/or RX180s.
- UBA
DS> ATTACH
Device type? DW780 ( or ) DW750 ( or ) DW730
Device link? HUB HUB HUB
Device name? DW0 DW0 DW0
TR? 3 * *
BR? 5 5 5
* = not applicable for this model
- RUX50
Example:
DS> ATTACH ! Attach
Device type? RUX50 ! the RUX50 controller
Device link? DW0 ! to the UNIBUS adapter
Device name? DUa ! a = controller designation (A, B, etc.)
IP? 772150 ! Typical IP address
VECTOR? 154 ! Typical vector address
BR? 5 ! Typical bus request level
- RX50
Example:
DS> ATTACH ! Attach the RX50 removable disk to its
Device type? RX50 ! RUX50 controller (DUa)
Device link? DUa ! a = controller designation (A, B, etc.)
Device name? DUan ! n = unit number
- RX31
Example:
DS> ATTACH ! Attach the RX31 removable disk to its
Device type? RX31 ! RUX50 controller (DUa)
Device link? DUa ! a = controller designation (A, B, etc.)
Device name? DUan ! n = unit number
- SELECT
Selects devices for testing. A diagnostic program will only test
devices which have been SELECTed. Devices specified in the SELECT
command must have been previously ATTACHed. Multiple devices may be
specified in one command.
For EVRNB, all disks to be exercised must be SELECTed. SELECTing
RUX50 controllers is optional and has no effect on program
operation.
General Format:
SELECT DUa, DUan [, DUan, ...]
Examples:
SELECT DU0, DUA0, DUA1
SELECT DUA0, DUA1, DUA2, DUA3
- EVENT
EVRNB does not support any user-alterable event flags.
- QUICK
EVRNB does not support use of the QUICK flag.
- SECTION
Defines the sections (/SECTION qualifier on RUN or START) which
this program supports. The Level 3 Exerciser for RUX50 (EVRNB)
supports the MANUAL program section in addition to the DEFAULT
program section.
The MANUAL program section allows the user to change various program
parameters and options before any testing takes place.
- DEFAULT
This section will exercise the RUX50 and all SELECTed devices
using default program parameters and options.
To run this section, type:
RUN EVRNB or
RUN EVRNB/SECTION:DEFAULT
or you can type:
LOAD EVRNB then
START or
START/SECTION:DEFAULT
- MANUAL
This section allows the operator to view and/or change various soft
parameters and options before any testing takes place. A series of
questions will be posed, along with the default answers and permissible
range of values. To select the default answer to any question, simply
type a carriage return. After all questions have been answered, the
program proceeds with testing, using the parameters chosen.
To run this section, type:
RUN EVRNB/SECTION:MANUAL
or you can type:
LOAD EVRNB followed by
START/SECTION:MANUAL
- SUMMARY
The SUMMARY command will cause the current Exerciser statistics to
be printed on the console terminal.
