===============================
1 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).

1 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)

1 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

   NOTE: For microVAX, there are no UNIBUS adapters; attach the LESI
   directly to the HUB.

2 UBA
   * = not applicable for this model

   DS> ATTACH
   Device type? DW780   ( or )   DW750   ( or )   DW730
   Device link? HUB              HUB              HUB
   Device name? DW0              DW0              DW0
   TR?          3                *                *
   BR?          4                5                *

   NOTE: The UBA is not ATTACHed under microVAX.

2 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: For microVAX, attach the LESI directly to the HUB.

2 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

2 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

1 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

1 EVENT
   EVRMA does not support any user-alterable event flags.

1 QUICK
   EVRMA does not support use of the QUICK flag.

1 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.

2 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

2 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

1 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.
