- HELP
The Level 3 Exerciser for RC25 (EVRMA) 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 RC25 drive will perform under stressful operating system conditions.
The Multi-Drive 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. In addition, the user can choose instead to run the
DM Exerciser Subtest. This subtest consists of the ROM-resident Front
Panel Test running in the DM (Diagnostic Machine) under host control.
This program can test up to 4 LESI controllers (4 different IP
addresses), each controller having up to 2 drives (1 master and 1
slave), and each drive with 2 platters (RC25 removable and RCF25
fixed).
- DEVICES
EVRMA supports the following devices:
Device type Device name
----------- -----------
LESI - RC(F)25 controller DAa
RC25 - removable disk DAan
RCF25 - fixed disk DAan
where a = controller designation (A, B, etc.)
n = unit number (from unit plug)
(Note: Some versions of the VAX-11 Diagnostic Supervisor require
the name "DU" instead of "DA").
- 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 EVRMA to exercise RC25 drive-units, the following
devices must first be ATTACHed:
UBA (UNIBUS adapter) - must be ATTACHed to the HUB
LESI (RC25 controller) - must be ATTACHed to the UBA
RC25 (removable disk) - must be ATTACHed to the LESI
RCF25 (fixed disk) - must be ATTACHed to the LESI
- UBA
* = not applicable for this model
DS> ATTACH
Device type? DW780 ( or ) DW750 ( or ) DW730 ( or ) DWBUA
Device link? HUB HUB HUB HUB
Device name? DW0 DW0 DW0 DW0
Node? * * * 1-15(D)
TR? 3 * * *
BR? 4 5 * 4
- LESI
Example:
DS> ATTACH ! Attach
Device type? LESI ! the LESI controller
Device link? DW0 ! to the UNIBUS adapter
Device name? DAa ! a = controller designation (A, B, etc.)
IP? 772150 ! Typical IP address
VECTOR? 154 ! Typical vector address
BR? 5 ! Typical bus request level
(Note: Some versions of the VAX-11 Diagnostic Supervisor require
the name "DU" instead of "DA").
- RC25
Example:
DS> ATTACH ! Attach the RC25 removable disk to its
Device type? RC25 ! LESI controller (DAa)
Device link? DAa ! a = controller designation (A, B, etc.)
Device name? DAan ! n = even unit number from unit plug
(Note: Some versions of the VAX-11 Diagnostic Supervisor require
the name "DU" instead of "DA").
- RCF25
Example:
DS> ATTACH ! Attach the RCF25 fixed disk to its
Device type? RCF25 ! LESI controller (DAa)
Device link? DAa ! a = controller designation (A, B, etc.)
Device name? DAan ! n = odd unit number from unit plug
(Note: Some versions of the VAX-11 Diagnostic Supervisor require
the name "DU" instead of "DA").
- 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 EVRMA, all disks (RC25 and RCF25) to be exercised must be
SELECTed. SELECTing LESI controllers is optional and has no effect
on program operation.
General Format:
SELECT DAa, DAan [, DAan, ...]
Examples:
SELECT DAA, DAA0, DAA1
SELECT DAB4, DAB5
(Note: Some versions of the VAX-11 Diagnostic Supervisor require
the name "DU" instead of "DA").
- EVENT
EVRMA does not support any user-alterable event flags.
- QUICK
EVRMA 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 RC25 (EVRMA) 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 all SELECTed RC25 (and RCF25) platters
using default program parameters and options.
To run this section type:
RUN EVRMA or
RUN EVRMA/SECTION:DEFAULT
or you can type:
LOAD EVRMA then
START or
START/SECTION:DEFAULT or
- 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 in the normal manner.
To run this section, type:
RUN EVRMA/SECTION:MANUAL
or you can type:
LOAD EVRMA followed by
START/SECTION:MANUAL
- SUMMARY
The SUMMARY command will cause the current Exerciser statistics to
be printed on the console terminal. The actual format of the Summary
Report depends on which subtest was run. The Multi-Drive Subtest does
not keep the same set of statistics as the DM Exerciser Subtest.
