SYSERR.DOC -- Changes from V10A(555) to V12A(1013)
August 1978
1.0 SUMMARY
SYSERR is a program used to list the contents of the system error
file. It is the report generating portion of the DECsystem-10 Error
Detection, Recovery, and Reporting package.
SYSERR Version 12A(1013) runs on TOPS10 Version 603A.
SYSERR Version 12A(1013) requires DAEMON Version 16(612)
SYSERR uses HELPER and SCAN.
Documentation on how to run SYSERR and descriptions of report formats
may be found in the TOPS10 and TOPS20 SYSERR Manual (AA-D533A-TK).
2.0 EXTERNAL CHANGES
This release of the SYSERR package includes the following new
functions:
1. Re-order signal names for the KLERROR report to get all error
signals to the top.
2. Add /SEQuence switch to extract individual entries.
3. Add /BRief switch for 2 line entry format.
4. New page headers contain SYSERR version #, and system S/N.
5. /NDEV switch handles generic device names.
6. Supports MTA thru MTD (8 drives) and RPA thru RPD (8 drives).
7. /NOW switch to support real-time error logging.
3.0 KNOWN BUGS AND DEFICIENCIES
There is a problem with MASSBUS disk unit errors where the drive
registers may not be saved. This causes an error message from SYSERR
to be printed on the terminal. The message is as follows; %ILLEGAL
MASSBUS UNIT TYPE -- ABORTING ENTRY. SYSERR will then continue to do
the rest of its processing in the normal manner. This problem is
fixed by MCO 8153 which is in 6.03A and later versions of the
monitor.

Software Notebooks.
2.0 EXTERNAL CHANGES
2.1
SYSERR V3B contains several external changes which are fully
documented in the Software Notebooks as referenced in section 1.3 of
this document. Included here are brief summaries of these changes.
2.1.1
Massbus Device Error Reporting is the most significant external change
in this release. The report generated in the listing file contains
the device name, media ID including the structure name, User's ID
program name and filename, all of the controller (RH10) status and all
of the device (RS04 or RP04) status including all of the registers in
the device. Sample listings and descriptions are found in SYSERR.RNO.
SYR3B.DOC Page 17
2.1.2
SYSERR V3B automatically looks for and processes the extended error
files ERROR.X01 thru ERROR.X77 created by DAEMON V10 and later. Upon
detecting an error using ERROR.SYS, DAEMON begins saving the error
information in ERROR.X01. SYSERR will look for these files after
encountering EOF on ERROR.SYS and start processing extended error
files according to the same commands after informing the user on his
(her) terminal and making a notation in the output file.
2.1.3
The summary listings included at the end of all output files now
include the name and creation date of all extended error files
processed and a breakdown of system reloads by type indicating the
number of each type which have occured. Also the listings for error
counts by device only include those devices which had errors and not
all devices on the system.
2.1.4
The default output file name has been changed from ERROR.LST to
XXXXXX.LST where XXXXXX is the main switch specified in the command
such as /DSKALL or /CPUPER etc. This allows multiple passes of SYSERR
to not overwrite the defaulted output file.
2.1.5
A new /STR:NAME Switch has been added to allow only those errors
concerning a specific structure regardless of the device it was
mounted on. This switch is only applicable to disk or massbus units.
2.1.6
SYSERR no longer needs to be assembled to build a site-dependent
configuration.
2.1.7
SYSERR V3B now closes the input and output files when detecting a
fatal error and preserves the reports generated before the error.
SYR3B.DOC Page 18
3.0 KNOWN BUGS AND DEFICIENCIES
None.
4.0 INSTALLATION INSTRUCTIONS
SYSERR no longer needs to assembled on-site to generate the proper
configuration.
5.0 INTERNAL CHANGES
Internal changes in SYSERR V. 3B include those to support the external
changes and definition of the full range of error codes. This
definition was in order to prevent both DEC and customer using the
same error codes in the future. The definition is documented in
ERROR.RNO.

SYSERR.DOC -- V3
December 1973
1.0 SUMMARY
This release provides for Magtape Error Reporting and handles
multi-controller (DPX,FHX,MTX) tables to be generated on the
basis of system configuration.
SYSERR version 3 will run on all 5.06 and later monitors. It
has been tested on 5.06 and later monitors, and fully
supersedes all previous versions. SYSERR version 3 works with
DAEMON version 7 under 5.06 monitors, but magtape errors are
not reported. To obtain reports on magtape errors, SYSERR
must be used with DAEMON version 10 or later and 5.07 or later
monitors.
For further documentation see SYSERR.RNO, and ERROR.RNO in the
Software Notebooks.
2.0 EXTERNAL CHANGES
2.1 SYSERR version 3 incorporates several new switches to support
magtape error reporting. These include:
/MAGALL - list all magtape entries
/MAGPAR - list magtape parity error entries
/MAGPER - list magtape performance entries
/MAGSUM - list magtape summary statistics
2.2 New Performance Switches
In addition two switches have been added to allow error
criteria specification for performance entries. These
switches are:
/SRE:# - SOFT read error threshold (default 4)
/SWE:# - SOFT write error threshold (default 7)
When the user specifies /MAGPER he will receive magtape
performance entries which have 4 read errors or more and 7
write errors or more. These default values are assembly
parameters called SREDEF and SWEDEF respectively. The use of
the /SRE:# and /SWE:# switches override the default value for
that run. This allows dynamic control of error thresholds by
the user.
SYR3.DOC Page 21
2.3 Expanded /DEV Switch
Generic devices may be specified when using the /DEV:NAME
switch. Thus /DEV:DPA will list all DPA controller entries,
while /DEV:DP will list all DP controller's entries.
/DEV:FHA0 will continue to function as normal.
2.4 New /ID:NAME switch
A new /ID:NAME switch has been added to allow selection of
entries on the basis of the pack or reel identification. The
user can specify a single pack or reel name and only those
entries corresponding to that particular id will be listed.
2.5 Magtape Error Entry
The first new entry type is magtape error (code 20). The
format of the entry when listed is as follows:
***************************************************
MAGTAPE ERROR(CODE 20) LOGGED ON 16-JUL-73
AT 10:37:30 MONITOR UPTIME WAS 3:55:05
***************************************************
MAGTAPE PARAMETERS
UNIT NAME: MTA0
REEL IDENTIFICATION: REELID
OPERATION: READ MULTIRECORD
STATUS: 800 BPI, EVEN PARITY
ERROR DIAGNOSIS
RECOVERABLE TAPE PAR ERR,
ERROR ANALYSIS
ERROR LOCATION: RECORD 37. OF FILE 10.
CONI TMS AT ERROR: 0,20004 = TAPE PAR ERR,
CONI TMS AT END: 0,104 = NO ERROR BITS DETECTED
RETRIES PERFORMED: 4.
2.5.1 Unit Name - The Unit Name is the physical name of the magtape
drive. MTA0 represents unit 0 on controller A.
2.5.2 Reel Indentification - The Reel Identification is the name
supplied to the monitor at the time of mounting. It is not
contingent on any label information on the tape.
2.5.3 Operation - The operation is the activity of the drive at the
time of the error. Examples are read, write, read compare.
2.5.4 Status - This is essentially a text explanation of the status
bits found on in the CONI word in the entry. Examples are odd
parity, 7 or 9 track, write locked, etc.
SYR3.DOC Page 22
2.5.5 Error Diagnosis - The error diagnosis section is a definition
of the cause of the magtape error. It tells whether the error
was found to be recoverable or non-recoverable. It also gives
text explanations of the error bits in the corresponding CONI
word. If the error was hardware or relevant software counters
if the error was software-detected.
2.5.6 Error Analysis
The breakdown of last magtape error is the pertinent error
information about the last magtape error.
2.5.6.1 Error Location - This gives information as to the physical
location on tape where the error occurred. Repeated
indications of errors in the same location may suggest a bad
spot on tape or incompatibility between drives.
2.5.6.2 Coni Tms At Error - The Coni Tms At Error gives an octal
typeout of the CONI tms word as well as a text explanation of
error bits found on in the CONI tms word.
2.5.6.3 Coni Tms At End - The Coni Tms At End gives an octal typeout
of the CONI tms at the end of recovery attempts on the drive.
A text explanation of error bits is also provided.
2.5.6.4 Retries Performed - This is the number of times recovery was
attempted on the unit before a successful recovery or the
error was determined to be non-recoverable.
SYR3.DOC Page 23
2.6 Magtape Statistics (code 41)
The second type of new entry is the magtape statistics entry.
The following is an example of a magtape statistics entry
(code 41):

5.0 INTERNAL CHANGES
5.1 New Entry Types
Two new entry types have been added to support magtape error
reporting. These are error code 20 (ER.MAG) and error code 41
(ER.MSC). The ER.MAG entry will be similar in structure to
the disk unit error while the ER.MSC will be similar in
structure to the disk statistics entry.
The user is referred to the document ERROR.RNO in the software
notebook specification section for descriptions of entry
formats in the ERROR.SYS file.
5.2 New /DEV implementation.
The code for the /DEV switch now recognizes generic names such
as /DEV:DP for all units on any dp controller and /DEV:MTA for
all units on controller MTA.
5.4 New /ID:NAME Switch
Code was added to the logic to allow the selection of entries
based on the pack or reel identification name. The user
specifies the desired name by putting a /ID:NAME switch in his
command string.
5.4 Configuration Dependent Tables - SYSERR version 3 creates its
tables according to assembly parameters xxxnum. Where xxx is
DPA-DPD controller or FHA-FHD controller or MTA-MTD
controller. Each assembly parameter specifies the number of
units on the controller. This cuts down on the size of SYSERR
and allows multi-controller systems to be supported easily.
5.5 New Date Standard
SYSERR version 3 now is fully compatible with the new
DECSYSTEM-10 date standard. This allows use of SYSERR after
1975 without conversion.
