	Below are 20 Questions and Answers we compiled on Vaxsimplus.
    
    	Alan.
    
    
                        VAXSIMPLUS QUESTIONS
                     -------------------------

1. HOW DOES AN SDD NOTIFY DIFFER FROM A NORMAL RDC NOTIFY?

   call type is sdd
   problem summary includes vaxsimplus & event code
   Only the 1st FRU that Spear Suggests will be called out (unless repeat call)

2. WHAT ARE THE FULL NAMES OF THE COMMAND FILES THAT ARE INVOLVED 
   STARTING VAXSIMPLUS PROCESS AT BOOT TIME?

   sys$common:[sysmgr]sdd$startup.com
   sys$common:[sysmgr]systartuo_v5.com
   @sdd$exe:vaxsim$startup

3. WHAT IS THE EFFECT OF THE VAXSIMPLUS PROCESS NOT RUNNING?

   display appears to work but never clocks up any more errors  
   fault monitor will never have thresholds exeeeded

4. HOW CAN YOU TELL IF VAXSIMPLUS CAN SEND MAIL?

   by sending a test mail    (vaxsim/f mail summ test.tmp)

   by invoking errors ie injecterr to see if mail sent

5. WHICH FILE HAS TO BE ACCESSED BY EVERY NODE?
   HOW CAN YOU READ AND UPDATE THIS FILE?

   vaxsim$cluster.dat
   read: vaxsim$dump.com - output file  @sdd$exe:vaxsim$dump
   update & repair: vaxsim$fix.com - @sdd$exe:vaxsim$fix

6. WHAT IS MEL?

   mel is no longer used ?

   .mel is the output file from vaxsim/merge


7. WHAT IS VAXSIM/MERGE

   vaxsim/merge is a utility that allows you to create a single output
   file from multiple error log files, also it eliminates duplicate events.

8. NAME THE MAJOR LOGICALS NAMES USED BY VAXSIMPLUS.

   sdd$dat, sdd$exe, sdd$logs
   vaxsim$batch, vaxsim$errorlogs, vaxsim$mailbox, vaxsim$alias

9. NAME THE ONLY VAXSIMPLUS MANUALS THAT CAN BE LEFT ON A CUSTOMERS SITE.

   Getting started with Vaxsimplus
   Vaxsimplus User Guide
   Release Notes

10.DURING THE INSTALLATION AT WHICH POINT DO YOU ISSUE THE WARNING NOT TO USE
   THE HELP COMMAND? AND HOW WOULD YOU DO IT?

   when you get to the point in the installation where vmsinstall prompts:
   Do you want the vaxsimplus release notes queued to sys$print?

   one method would be to send a system messgae to all the users (opcom)
                (reply/all/bell "Please do not use help for 20 mins.")

11. BEFORE YOU MAKE ANY CHANGES USING VAXSIM$FIX WHAT PRECAUTION SHOULD
    YOU TAKE?

    run it in debug mode to ensure that correct data has been selected

12. WHEN VAXSIMPLUS IS INSTALLED HOW DO YOU INFORM IT THAT ERRORS FROM
    PREVIOUS DAYS EXIST

    @sdd$exe:vaxsim$loader.com
    (procedure to create vaxsimplus database from the existing errorlogs.)

13. WHAT IS THE AFFECT ON THE FAULT MANAGER  a) ALTERING THE MARGIN
    b) CHANGING THE CLIPPING LEVEL.

    there is no affect on the fault manager.

14. ON THE DISPLAY YOU CAN GO UP OR DOWN FOUR LEVELS FROM THE SYSTEM LEVEL,
    WHAT ARE THESE LEVELS CALLED?

    sub-system level
    unit
    error class
    error detail

15. HOW MANY WAYS CAN THE THRESHOLD BE EXCEEDED?

    thresholds can be exceeded by hard errors, soft errors, media errors or
    information errors by the display or fault manager.

16. WHAT IS MEANT BY THE FACT THAT SYS$COMMON AND V4COMMON ARE SYNONM 
    DIRECTORIES? WHAT IS THE V5 EQUIVALENT OF V4COMMON?   
  
    synonym directories are the same directories
    vms$common

17. WHAT DATE SHOULD THE CONTRACT EXPIRATION DATE BE SET TO?

    three months after the system contract expiration date

18. WOULD YOU NORMALLY INSTALL COMPUTE,INSTRUCT AND VSR?  WHY?

    compute - no - statistics package, waists system time
		 - at boot time allows customer to say why system went down.
 
    instruct - yes - instruction course for Spear Basic

    vsr - only if there is an 86** cpu in the cluster

19. HOW DOES SPEAR BASIC AFFECT VAXSIMPLUS?

    Spear Basic is nothing to do with Vaxsimplus
    (Spear Extended code is embedded in Vaxsimplus to generate event codes)

20. WHAT IS VAXSIM$ALIAS USED FOR?

    To identify the cluster for mail notifications.

55.5USIM - introductory details.COMICS::TREVENNORA child of initThu Sep 07 1989 14:0139
    
    
  What is USIM?
    
    
    USIM is the ULTRIX equivalent of VAXSIM-PLUS for VMS. It performs
    the same functions in a similar way.
    
    
  Limitations:
    
    Until host-based shadowing comes about auto-copy is not supported
    in USIM. In the first version no graphical interface is provided
    for USIM, though this may well be added.
    
  When?
    
    USIM will ship with Ultrix V4.0 (The BIG one!) early to mid of CY 90.
    
  Who is doing what?
               
    I am tasked with creating the bulk of the documentation for the product
    which is being written by Ultrix engineering. I already have a
    simulator for the native UNIX style user interface, and will shortly
    have a simulator for the Natural Language interface. At some later
    stage access to these can be given - Alan James and I have been
    discussing this. I would like to hear from anyone in the CSC who would
    like to be involved with the USIM project in an advisory role vis-a-vis
    its usability. 
    
  What systems?

    USIM will run on ULTRIX/32, ULTRIX/RISC and later on A.N.Other Open
    operating system whose existence we don't yet talk about (though I'm
    sure you've heard). It will provide commonality tools to allow
    imported, processed ULTRIX error log files to be used with VAXSIM
    and (probably) vice versa.

 All,

 Please find below a white paper/article written in response to a
 legal protest by Berkshire Computer Products to a sole source
 government contract. This article covers the reasons why a
 non-digital device is NOT compatable with VAXsimPLUS.

 This article has been reviewed by legal for distribution

          SUBJECT:	VAXsimPLUS compatibility with non-Digital
                  	drives

          There are three major categories of information re-
          quired by the VAXsimPLUS knowledge-base in order for it
          to provide the analysis and predictive diagnosis. These
          categories are:

          1. Error information and associated codes,

          2. Device geometry tables, and

          3. Failure signatures

          Error information is obtained from the system er-
          ror/event log in VMS . The information placed here
          is obtained from two sources; controller detected er-
          rors and drive detected errors. These error packets
          contain the associated Mass Storage Control Protocol
          (MSCP) error codes. These MSCP codes are specific to
          the drive type and have meaning specific to that de-
          vice. An example is that an MSCP code of XX for an RA82
          does not have the same meaning as an XX for an RA92.

          The VAXsimPLUS knowledge-base has been coded to under-
          stand these differences. If an MSCP code is received
          from a device which attributes different meaning to
          that code, VAXsimPLUS will be unaware of this and would
          make inappropriate assumptions. Since these codes are
          specific to the device design, it is unlikely that a
          non-Digital device would have the identical design and
          attribute the exact same meaning to that code.
 


                                                           Page 2



          The second piece of information required by the knowledge-
          base is the exact device geometry. Geometry, in this
          instance, refers to the number of heads, cylinders
          and LBNs. Hard coded into VAXsimPLUS is the expected
          geometry for the Digital RA series disk drives. A sim-
          ple MSCP command will confirm the geometry differences
          between the Digital RA series drives and other, non-
          Digital drives. No non-Digital drive geometry tables
          exist in VAXsimPLUS.

          If a non-Digital drive reports itself as a legitimate
          RA series drive, then the geometry table of that RA
          drive will be falsely applied to the non-Digital drive.
          This could result in incorrect assumptions as to the
          physical distribution of errors within the drive and
          thus, incorrect diagnosis by the knowledge-base engine.


          The third category of information required by VAXsim-
          PLUS is failure signatures and device specific rules.
          Any given device will fail in a manner specific to that
          class of devices. For instance, an RA82 will not fail
          in the same way as an RA92. The design of the device,
          the circuitry and mechanics used to build it and even
          the specific components used in these designs have
          their own unique failure signature.

          The VAXsimPLUS rules have been constructed to recognize
          the failure signatures of the RA series devices and
          to make predictions based on them. There are no non-
          Digital device rules coded into VAXsimPLUS.

          If a non-Digital drive is analyzed using these rules,
          an incorrect diagnosis/prediction is a virtual cer-
          tainty. Although the functions may be identical between
          the two drives, differing designs, circuitry and com-
          ponents used by these devices will result in different
          failure signatures.
 


                                                           Page 3



          In summary, even if the first condition is met and a
          non-Digital drive is 100% MSCP compliant and produces
          the error codes exactly like the equivalent RA series
          drive, it is still not compatible with VAXsimPLUS
          because of points 2 and 3. These last two points cannot
          be met without modifying the code which is protected
          under copyright and has two patents pending.

Subj:	Emanuel Tucker's (Logistics) trip report from CX, worth reading!!

To all

  During Emanual's visit we attempted to understand/quantify and document
the impact on logistics for the SDD tools.  The attached report has the
details and I feel is worth reading through, its nice to see the
benefit to Digital of the tools everyone is working so hard on and by the way
doing a great job!!!

  We attempted to keep the attached report as factual as possible and left
the subjectivity out.

 In summary

 The automation of the tools (ERFs,SPEAR,VAXsim) through VS+/SISR reduce
service calls by about 30% (this is very significant).  We only calculated
savings for the RA8X for, we have the most information on this device family,
because of the volumes the ROI are significant.

 Some of the more interesting data is, there are around 56,970 systems
under contract not using our tools, if we could get our tools utilized, it
would represent aprox 50 mill/yr expense reduction for RA8X devices alone.

  This savings is only based on RA8x devices, we have not figured in the other
devices.

  This is a great statement of benefit to the work you all have been doing,
Thanks much!!!

     Subject: CXN Trip Report- Sept 26, 27

     The purpose of the trip to CXN on Sept 26, 27 was two-fold:

     1] to develop with CSSE, a model to describe the impact of SDD/
        SISR on Consumption.

     2] to participate in a review of the CSSE Fault Management
        Operations Plan.

     My host was Andy Oppenheim (CSSE Fault Management Senior Manager).

     Analysis Process:
     ----------------

     The large majority of this report is devoted to a review/analysis
     aimed at the development of a model to describe the impact of
     SDD/SISR on consumption.  This study centered primarily around
     the data in eight tables which summarize:

        - the impact of SDD on calls, diagnosis time, RAXX consumption
          and RAXX NPF

        - SDD tool accuracy

        - VAXsimPLUS utilization

     Conclusions:
     -----------

        - THE KEY TO SUCCESSFUL IMPLEMENTATION OF SDD IS THE AUTOMATIC
          UTILIZATION OF THE VARIOUS SDD TOOLS.  THIS CONCLUSION IS
          SUPPORTED BOTH BY THE US PILOT (VINSON) AND THE EUROPEAN
          PILOT RECENTLY COMPLETED IN FINLAND.

        - Automated SDD (i.e., VAXsimPLUS for RAXX disks) reduces RAXX
          consumption by up to 33% depending upon the level of VAXsimPLUS
          utilization and NPF rate.  The NPF rate determines the maximum
          consumption opportunity. The level of VAXsimPLUS utilization
          determines the extent to which this opportunity can be realized.

        - Approximately 22% of the world-wide VAX installed base utilizes
          VAXsimPLUS, leaving the remaining 78% as "fertile ground" for
          future VAXsimPLUS utilization potential.

        - As a function of automated SDD, there is an opportunity to
          reduce consumption for non-RAXX products, but no data
          currently exists to quantify the magnitude of this opportunity.
          The CSSE Fault Management Group has set a goal of 10%
          consumption reduction for non-RAXX products which are capable
          for SDD (i.e., CPUs, tapes, other disks ... ).

     Next Steps:
     ----------

        - Service Delivery must formulate a long-range automated SDD
          utilization plan.

        - Logistics must determine if the product plans for RAXX products
          correctly accounts for VAXsimPLUS consumption impact, adjusting
          these plan as appropriate.

        - For the current products with significant consumption reduction
          potential, CSSE Fault Management must determine if/how SDD
          could be applied and then implement an aggressive plan to add
          this SDD capability.

        - For new products, Logistics must understand how SDD will enable
          consumption avoidance, adjusting the long-range plan as
          appropriate.

     Wednesday, Sept 26: Andy Oppenheim (CSSE), Keith Brown (CSSE)
     -------------------------------------------------------------

     - A detailed review of SDD was made:

     	- ERF (Error Reporter Formatter is the Error Logging Bit-to-text
      	  Report generator delivered as an integral part of the VMS/
     	  ULTRIX operating system.  It was offered in 1977 on VMS and
     	  1986 on ULTRIX.  The ERF concept began in 1972 as SYSERR on
     	  DECsystem 10's.

     	- SPEAR Basic is a summary generator which extracts significant
          error information from the system error (event) log and
     	  performs a summary.  It is capable of sorting on specific
     	  devices/event types.  Under VAXsimPLUS, Spear Basic has been
     	  renamed to Merge Error Log (MEL), a more descriptive title-
     	  the MEL program takes the collected error logs, merges them
     	  into a single file and strips off redundant entries such as
     	  HSC broadcast messages.  SPEAR Basic was developed in 1983
     	  and exists only under VMS today.

        - SPEAR Extended (Analysis) takes the output from SPEAR Basic,
     	  applies a rule-based system to perform single and multiple
     	  event correlation to determine the suspected FRU and/or
     	  action to be taken to recover.  SPEAR Extended was developed
     	  in 1983 and exists only under VMS today.

        - Using the RA81 as an example, from approximately 230 unique
          error report types, SPEAR Extended utilizes approximately
     	  67 non-media and 18 media specific algorithms to look for
     	  failure signatures.  These algorithms will then indict the
     	  appropriate FRU (one of five).

     Consistent, accurate usage of MEL (SPEAR Basic) and Analysis
     (SPEAR Extended) will yield increased field call-out accuracy.

     VAXsimPLUS was created for RAXX disks to insure consistent and
     accurate usage of MEL and Analysis by automating the process,
     removing the decision to run the tools from the field engineer
     and placing the decision with the operating system.  By
     automating this process, we have the capability to dynamically
     monitor soft or recoverable error events and look for specific
     failure signatures.  This provides the capability to invoke a
     service request prior to catastrophic failure (i.e., predictive
     maintenance).

     To the above tools, VAXsimPLUS adds an automatic monitoring,
     notification and autocopy function:

     	- "Monitor" automatically classifies the error events into
     	  "buckets", for each device, to be displayed as well as
     	  set up for the Analysis program.

     	- "Notify" sends VAXmail messages to the designated mail lists
     	  as well as initiates Autocopy.

                - If this notification is sent to the Customer to
     		  initiate corrective action, then this activity is
     		  called Customer Initiated Service Request (CISR).

     		- If this notification is sent to the CSC (Digital)
     		  to initiate corrective action, then this activity
     		  is called System Initiated Service Request (SISR).

     	- "Autocopy" invokes Volume Shadowing to copy the data from
     	  the suspected candidate drive to a spare drive.

     - more re VAXsimPLUS:

     	- Enables the automation of the corrective action/field
     	  dispatching process.

     	- Deployment began in 1987.

     	- VMS only today.

     	- Enables a uniform, consistent, predictable corrective
     	  action, resulting in both a more accurate and faster
     	  diagnosis when compared to a manually-driven system.

     	- During SISR, the customer is also notified that a repair
     	  plan is being put into place.

     - NOW FOR THE SPECIFIC RESULTS:

     	NOTE: THE MAJORITY OF THE SAVINGS WHICH FOLLOW ARE CENTERED
     	      AROUND RA DISKS.  THIS IS THE AREA WHERE THE ROI
     	      IS THE GREATEST AND WHERE, TO DATE, THE PRIMARY EFFORT
     	      HAS BEEN PLACED ON CREATING ALGORITHMS AND ANALYSIS
     	      IMPROVEMENTS.

     	      CLEARLY, THERE ARE OTHER AREAS OF SIGNIFICANT RETURN
     	      THAT MUST BE ADDRESSED.  LOGISTICS IS LOOKING TO
     	      THE FAULT MANAGEMENT CSSE GROUP TO TAKE A LEADERSHIP
     	      ROLE IN ADDRESSING THESE OPPORTUNITIES.

     		David Bell, 31 August 1990.

     - There is a strong correlation in these two pilot regarding
       the percentage reduction in calls.

     - It is important to note that the US Pilot report attributes
       savings to SSPs ... this can be quite misleading.  The savings
       detailed in this report are due to the implementation of
       SISR and the automation of SDD and not due to the use of SSPs.
       SSPs were used as the service delivery platform on which to
       run the specific SDD/SISR applications ... other effective
       service delivery platforms would yield similar results.

     - Although the European Pilot made no conclusions regarding
       Consumption, Emanuel will initiate a discussion with David
       Bell to investigate the potential Consumption impacts of
       this pilot.

     	(4) VAXsimPLUS Info, David Bell, 20-AUG-1990

     - Note that conclusions from this report are being made on a sample
       of only two months of data.

     - The overall 4% NTF (No Trouble Found) of VAXsimPLUS compared to
       13% NTF for No VAXsimPLUS, indicates that VAXsimPLUS utilization
       significantly improves the accuracy of the field diagnosis.

     - VAXsimPLUS is doing an excellent job for the RA82.  This is
       especially significant in that the RA82 HDAs are swapped the
       most today (132 out of 248 swaps were RA82 HDAs).

     - The tool needs improvements for the RA81 and RA90 with the
       RA90 being the most urgent since the RA90 population will
       increase in the future while the RA81 population will decrease
       in the future.

     - HDA consumption has increased significantly over this period.

     	- An FCO was done on the HDAs in FY86 that affected the counts
          of HDAs for FY86 and FY87.  32,582 HDAs were shipped to the
          field under the EQ kit number instead of under 70-18491-01-
     	  hence these are not included in the numbers above.

     	- HDA wear-out factor (or HDA life cycle) is now considered
     	  to be 22 months.

     	These two major impacts "wash-out" any attempt to determine
     	potential SDD impact on RA81 HDAs.

     - In reference to the Microprocessor and Servo Bd FRUs,
       consumption has decreased appreciably (38% and 41% respectively)
       from FY88 to FY90 with total drive population remaining nearly
       constant.  With VAXsimPLUS deployment beginning in 1987, it is
       believed that one of the factors for this decrease in consumption
       is the usage of VAXsimPLUS.  Improved training/experience
       undoubtedly also contributed to this consumption reduction.

     	(8) per Andy Oppenheim, Bill Sutliff, Sept 26, l990.

     - With 16,030 systems currently utilizing VAXsim+, and an
       average of three drives/systems, 48,090 drives would produce
       a consumption savings of up to $13.849M.

     	- The $13.849M comes from $288 times 48,090 drives.

     	- The $288 comes from the projected US Pilot results
     	  which gave a potential savings of up to $288/disk.
     	  [ref TABLE 1]

     - The above analysis does not take into account potential
       material savings from non-RA devices for which VAXsim+ applies:
       [i.e., assuming SDD hooks are available ... ]

     	- CPUs: 9000, 3000, 6000, 4000

     	- Devices: RV, RF, TA, TF, DEMNA, KDM70

       For these product families a potential VAXsim+ savings impact
       of 10% should be assumed.  It is critical that pilots be run
       to verify this assumption- it is being stated only for planning
       purposes at this time.

     - Anticipated VAXsim+ consumption savings have already been
       factored into the product plans for the following products:

     Action: Emanuel Tucker will contact the above CSSE mgrs to
     	     understand VAXsim+ impacts on consumption for the
     	     these products.

     ****************************************************************

     - Currently, VAXsim+ does not effectively diagnose 86XX and
       memory products ... high NPF rates have been identified with
       these products.  CSSE has initiated efforts to understand
       the causes of this high NPF rate and extend SDD as appropriate
       to help reduce this phenomena.

     ----------------------------------------------------------------

     - The large majority of the day was spent reviewing the contents
       of the CSSE Fault Management Operations Plan.  Significant
       results of this review follow:

     	- Considerable concern was expressed about the lack of a "real"
       	  service delivery strategy.  Andy agreed to use the existing
       	  virtual Fault Management Team to draft a "straw horse"
          service delivery strategy.  Without this strategy, we cannot
          properly position our Fault Management tools to meet their
          objectives.

     	- A Fault Management LRP is needed.

     	- Fault Management must be expanded to include non-Digital
     	  products.

     	- Direct inputs from customers and field engineers is deemed
       	  critical- possibly CABs (Customer Advisory Boards) can be
     	  formed.

     	- On page 8, Logistics must be added to the pictorial
     	  representation of Fault Management CSSE Customers.  Emanuel
     	  suggested that Logistics be added along side of the Service
     	  Delivery inputs to insure a two-way dialogue between the
     	  Fault Management Virtual Team and Logistics w/r/t SDD Product
     	  Requirements.

        - Each virtual team member must be responsible for "delivering
          their respective organizations", i.e. act as a conduit/
     	  approval between their groups and the Fault Management Team.
     	  This will insure that conflicting Fault Management development
     	  requirements are minimized.

        - The tie-in with the DEFMA (Digital Equipment Fault Management
          Architecture is critical).  Frank Robbins is driving DEFMA.

     	- Release 1.7 of VAXsimPLUS is expected to enable the design of
          a modular SPEAR- thus significantly improving our ability to
          more easily apply SPEAR to new products.

     - Emanuel Tucker presented the latest results of the Logistics
       SDD Module Testing project:

     	(VINSON)

     		(9) SDD Module Testing Status Report,
     		    Colleen Castonguay, August 20, l990.

     	- The accuracy of the SDD/Predictive Maintenance Tools on RA
     	  series disks as measured by Customer Services Logistics is
     	  between 60% and 80% accurate.  This was based on the
     	  preliminary results of the SDD Module Testing project that
     	  is being conducted in CSL Engineering.

     	- The worst case scenario of 60% is based upon the analysis of
     	  95 VAXsimPLUS indicted RAXX modules from the US AREA where
     	  Logistics was able to correlate the field failure to a
     	  Logistics failure.

     	- The best case scenario of 80% is based upon the analysis of
     	  16 VINSON indicted RAXX modules.  We were able to demonstrate
     	  from CSL testing (No Problem Present) and from the field
     	  (VINSON and LARS) data analysis, that 20% of the FRU's
     	  from the customer systems did not correct the problem.

     -----------------------------------------------------------------

     	- SDD indicted modules are not returning at a rate consistent
     	  with the level of field indictment.  It was suggested that
     	  the process be refined using a specific field area/district
     	  to maximize two-way dialogue between the field and
     	  Logistics.  This "adopt a district" concept could have the
     	  additional benefit of providing access to LARS information

     	  and also provide a path for "repaired SDD modules" to return
     	  to the field.

     *****************************************************************

     Action: Emanuel Tucker will investigate with Stan Goldstein the
     	     practicality of a target area/district with which to work
     	     the SDD Module Testing Project.

     *****************************************************************

     The overall results of the SDD Module Testing project were
     considered consistent with analyses performed by CSSE on the
     accuracy of the SDD tools [ref TABLE 2].

55.10A fix for VMS 5.4KERNEL::MCGAUGHRINWhat a Marvelous DeliveryWed Dec 05 1990 09:24185

		Patch for SDD V1.2A to work on VMS V5.4
		---------------------------------------

	This is to announce the availability of a patch kit for SDD
	V1.2A that enables it to work under VMS V5.4. This patch is 
	intended to be used as a stop-gap until SDD V1.5 is available 
	to help customers who are migrating to VMS V5.4.

	This patch will not help customers buying new hardware such as
	the VAX 9000/4000/ft3000/RA92.  If these customers have a need
	for SDD and cannot wait for V1.5, then consider using the FT
	version (as I described previously).

	This patch is not expected to live very long.  It will be
	replaced with SDD V1.5 which will ship as follows :

		- with new systems as part of Factory Installed
		  Software program

		- from SSB as usual

		- with ISDS 0.3, as ISDS will be supporting the VMS V5.4
		  VAX 9000/4000/ft3000/RA92 environment.

	It is advantageous to use this patch where customers are simply
	upgrading to VMS V5.4 and do not require the new device support
	or bug fixes of SDD V1.5.  It is also relatively cheap to apply
	the patch as it is small, less than 15 blocks on the customer
	system, thus it can be done quickly during a site visit or
	remotely, or even, if required, by the customer himself.


	Capability:	This patch enables the existing VAXsimPLUS V1.2A
			to work under VMS V5.4 systems.

			It adds NO new functionality or device support
			(RA70/80/81/82/90 RF30/71 TA90)

			It fixes NO outstanding V1.2A bugs (TA90, AutoCOPY
			problems).

			If new functionality is required, then VAXsimPLUS
			V1.5 should be used.

			The patch may be applied pro-actively to VMS V5.x
			systems that will upgrade to V5.4

			Due to its small size it can be installed remotely
			if required.

	Operation:	This patch converts VMS V5.4 error log entries
			back to V5.2/5.3 format so that correct analysis
			may take place.

			The VAXsimPLUS monitor and the VAXsim/MERGE
			command support V5.4 without problem.  Only the
			VAXsim/Fault_Manager cannot handle the error
			log records.

			The patch installs 1 image and a CLD file
			to provide a utility to translate the temporary
			error log file used by VAXsimPLUS.

			It also updates VAXsim$NOTIFY.COM to invoke
			the new image.

	Pre-requisites: All that is required is an existing installation
			of VAXsimPLUS V1.2A.

	Installation:	Installation is may either be via a standard VMS
			installation or remotely.

			The full VMSINSTAL kit is 30 blocks, which is
			small enough to be downline loaded.  Alternatively
			the kit may be broken out and just the necessary
			files transferred.

			The installation checks for the presence of SDD
			and that the kit has not been previously patched.

			It asks no questions and will complete the patch
			in less than 5 minutes.

			The kit can be left on the customer site if desired,
			as it contains no proprietary information.

	Support:	All support issues/problems should be directed to
			ASDPO via the hotline (DTN 828-5111) for priority
			1 and 2 problems.

	Documentation:	Documentation is bundled within the kit itself.

			It is not left on-site when installation completes.
			A copy is appended to this message.

	Availability:	The kit is available now from

			CLARID::ASDPO1$:[BELL.PUBLIC.SDD]SDD_PATCH054.A


	Acknowledgements:	I am indebted to Chris Loane for his
				dedication, in providing all of us with	the
			 	utility to covert from V5.4 error logs to
				V5.2/5.3 and making it work for SDD V1.2A


			VAXsimPLUS V1.2A Patch Kit
			==========================


	Use this kit in 2 ways :

	- standard VMSINSTAL
	- downline load


	VMSINSTAL
	=========

	Just type

		$ @SYS$UPDATE:VMINSTAL SDD_PATCH054  directory_spec

	this will do the work and install the images in the proper
	place.  Check everything is OK - refer to the section below


	DOWNLINE LOAD
	=============

	Break up the kit and transfer the following files to the
	SDD$EXE directory :


		XLATERR.CLD
		XLATERR.EXE
		DO_PATCH.COM

	To install, just execute DO_PATCH to update the VAXSIM$NOTIFY
	file

		$ @DO_PATCH


	CHECK OUT
	=========

	Three new files should be created in SDD$EXE :

		XLATERR.CLD
		XLATERR.EXE
		VAXSIM$NOTIFY.COM

	There may also be a copy of DO_PATCH.COM as well if you downline
	loaded.

	Do a DIFF of VAXSIM$NOTIFY.COM (there should be at least 2
	versions).  You should see a single difference with the lines


		$ SET COMMAND XLATERR.CLD
		$ XLATE/INPUT='REPORT'.SYS/OUTPUT='REPORT'.SYS

	If its there, then all is OK.

	Installation will check for the presence of the SDD$EXE logical.
	If it does not exist then installation will fail with

	SDD-E-NOTFND Cannot find SDD$EXE directory


	Next it will check to see if XLATERR.CLD has already been installed
	in SDD$EXE.  If so, it assumes that the patch has been done and
	will not do it again

	If installation fails in any other way, remove the 2 XLATERR.* files
	from SDD$EX$ and start again.

    	This note explains how to patch VAXsimPLUS V1.2A remotely
    	so that it will continue to work once a customer has upgraded
    	VMS to V5.4
    
    	You should have read the previous note before attemting this
    	because you should be very clear about what the patch actually
    	does and more importantly does not do!
                      
    	You will find all the relevent files in rsds$spear, and there
    	is also a README.TXT which you may wish to browse through
    	before going ahead.
    
    	There are THREE files which need to be installed, and as usual
    	you should make a connection to the customers machine and 
    	login to the FIELD or privalleged account..

    	That is it! It should not take any more than a few minutes
    	then you can check to see if you have created a new file
    	called VAXSIM$NOTIFY.COM, if so then OK.
    
    
55.12SDD V1.5-127 RELEASEDKERNEL::MCGAUGHRINWhat a Marvelous DeliveryTue Mar 26 1991 13:3917

	The latest "final V1.5 kit" has been placed with the rest of
	the ISDS kits in the following location :

		CLARID::ISDS003:[CUST.SDD015]

	This kit will be sent to SSB on Monday 25-MAR-1991 for manufacture.

	Before copying read the READ_ME_FIRST file as it supplements
	the release notes.

	If you have any queries, I'll be out for the next 2 weeks ! :-)

	IMPORTANT-IMPORTANT-IMPORTANT-IMPORTANT-IMPORTANT-IMPORTANT
	-----------------------------------------------------------

		This SDD kit is currently the V1.5-127 kit.

	It fixes several problems related to the password generation
	on the SDD$MANAGER account.

	Note very carefully the following limitations :

	- VAX 9000 SPU and memory errors are not always handled
	  correctly.  Engineering says to rely on the SPU information

	- not all VAX 4000 CPU errors are reported.  There will be
	  a patch to fix this in the future

	- when upgrading a V1.2A site it is recommended that the
	  VAXsim$CLUSTER.DAT database be deleted before upgrading,
	  followed by VAXsim$LOADER to reload information.

	  BUT remember to save a copy of the mail list if you do
	  this as it is held in this database!

	If you have any questions concerning SDD, please contact me.

55.14[1.15.8.10] Are they injected errors?KERNEL::MCGAUGHRINWhat a Marvelous DeliveryThu May 16 1991 18:3565
    
    
    It is important that you are able to recognise whether a drive has
    had errors injected onto it. Otherwise you could be sending engineers
    to site un-necessarily. This reply explains what to look for.
    
    
    1. INJECTERR

    INJECTERR  is  a  program written in Macro to inject DSA disk errors 
    into a System Errorlog primarily for  demonstrating  the  SDD  Tools 
    Kit  functionality.  It can also be used to verify correct operation 
    of the Tools Kit after installation.

    It should be noted that INJECTERR will leave errors  in  the  System 
    Errorlog  file, but will NOT show up in the output of the SHOW ERROR 
    command (Basically, it doesn't  increment  the  Device's  UCB  error 
    count field)

    Set-up :

	INJECTERR resides in the  SDD$EXE directory  with the SDD Tools.
	Before running  INJECTERR you must set up your command tables by
	typing the following :

	$ SET COMMAND SDD$EXE:INJECTERR.CLD

    Use :

	The full format of the command to inject errors is as follows:

        $INJECT $2$DUA7/AFTER=0:0:10/DELAY=0:0:30/COUNT=6/CLASS=MEDIA/BELL


   2. SDD FUNCTIONS

   Once errors have been injected and the drives monitor threshold has been
   exceeded (warning condition), vaxsim then triggers. It then collects the
   Errorlog data, analyses that data for a failure mode (theory), and if one
   is detected then it sends mail. 

   If you inject MEDIA errors, the vaxsim theory received will be [1.15.8.10]
  
   3. DSNlink (AES - SISR)

   Given the scenario that an engineer wishes to test that both VAXsimPLUS
   and SISR are working correctly, then he can use INJECTERR to do this.
   Typically he will inject MEDIA errors, this will cause mail to be sent
   to those on the mailing lists, also you will find that if DSNlink (AES)
   is installed, then it will attempt to log a request into NICE at the
   CSC. The Problem Description in the NICE request will include the VAXsimPLUS 
   Event Code [1.15.8.10]. 
   
   4. How to spot INJECTED errors

   If you are dealing with *ANY* VAXsimPLUS event code of [1.15.8.10], then
   you should be able to recognise whether these errors have been injected
   or whether they are real. The tool INJECTERR was specifically designed in
   such a way so you CAN recognise injected errors. The LBN to which these
   errors are targeted is 48879, this when converted into HEX = BEEF (RF**
   drives check Command Reference Number) Also you can check the time span 
   of these errors from the mail messages and determine whether it is 
   likely that these have been injected. 

                              
55.15Operator Requested Shutdown SICL callsKERNEL::LOANEComfortably numb!!Wed Jul 14 1993 13:2235
    Recently  calls  logged  via  AES  have  indicted Operator Requested 
    Shutdowns. These come in 2 flavours; calls logged by CLUE and  calls 
    logged  by  VAXsimPlus.  Could  I  ask  you  to forward this mail to 
    whoever you believe may get one of these  calls  so  we  can  gather 
    information to discover the root cause.
    ********************************************************************
    Firstly, calls logged via CLUE.
    CLUE  is  installed  (optionally) with SDD and with AES. However, in 
    Europe, the ability for CLUE to log calls via  AES  was  turned  off 
    (the file SDD$EXE:CLUE$STARTUP.COM has the following line:-

$ !define/system/exec clue$log_call     TRUE

    I  believe  that  this line is being un-commented in which case, the 
    CLUE$STARTUP.COM procedure will  call  SDD$EXE:CLUE$LOG_CALL.COM    
    ********************************************************************
    Secondly, calls logged via VAXsimPlus.
    We  have  experienced  problems  with  VAXsimPlus  logging SysBugChk 
    and/ot CrshRstrt events....but the errorlogs  supplied  are  nothing 
    to  do  with  the  event  (typically, the errorlogs contain some Bus 
    errors). To provide a workaround  to  the  problem,  a  `patch'  was 
    written  for  the  file  SDD$EXE:FMGR$BUILD_SISR.COM.  This involves 
    adding the lines:-

$ melselect = "/entry=(40,37,2,112)"		![CL] Check SysBugChk etc
$ gosub melcount				![CL] Count those records
$ if rec_ltd .gt. 0 then goto gotmel 		![CL] Got records, melselect ok

    I'd  be  interested in knowing if this (patched) version of the file 
    is on the system logging  Operator  Requested  shutdowns  and  also, 
    what  version  of  VAXsimPlus is installed (typing VAXSIM at the DCL 
    prompt will tell you).

    Cheers
    	Chris
