1100/84 DUMPS
PURPOSE
1. The procedures contained herein cover the 1100/80 dump processes
which copy the contents of main storage to tape or disk. There are two
methods for accomplishing system dumps: AUTO RECOVERY PANIC DIDIP and
OPERATOR INITIATED PANIC DUMPS.
REFERENCE
2. UNIVAC Manual (UP-7928) 1100 Executive System Operator Reference
Manual. TM 184 System Dumps 30 July 1982.
DUMP PROCESSES
3. AUTO RECOVERY PANIC DUMP (ARPD)
a. An ARPD is initiated by the 1100 operating system without
operator intervention when a system error is detected and the
System Transition Unit (STU) processor panel select Jump switch
"3" (Suppress Auto Recovery) is not set. Upon completion of
the dump the operator is given the message:
0 - Save Panic Dump to Tape or Mass Sotrage? T, M, NO
At this time bring up a tape drive and mount a scratch tape.
Answer the console message with a "T" (for tape). The dump
is then written to tape for printing and system error analysis.
Rebooting is not required.
a. 150 STOP - This is initiated by the operator entering "$!"
on the system console. Generally this is the preferred way for
the operator to initiate a dump. This can be used to recover
and dump a system "HANG", (provided the console will accept
keyins), a run that cannot be 'X'ed or to clear the console
when a stream of messages are preventing normal operation.
b. MANUAL DUMP - This is initiated by the operator booting
the system with Jump key 2 set. This type of dump should be
taken when a 150 STOP can not be taken on a hung system because
the console won't respond, zero stop occurs or when Auto-Recovery
fails.

c. ON-LINE DUMP - This type of dump is initiated by the
operator keyin "DU MP" on the system console. This type of
dump has limited value. When there is poor system performance
or when system abnormalities are noticed the ON-LINE DUMP
would be initiated. This dump does not stop the system and
does not cause a reboot.
Caution should be exercised in using the ON-LINE DUMP. Real-
time programs may lose communication data, so if Real-Time
programs are running in the system, they must be made inactive
prior to proceeding with the dump. Otherwise the ON-LINE dump
does not cause any runs or files to be lost.
It does however stop all system activity momentarily with the
effect that no jobs will run, terminals will not receive any
responses, and the console will not respond to inquiries.
5. SYSTEMS MAINTENANCE UNIT (SMU)
a. The SMU may be used to record system registers -in the
case of a system hang, or a zero stop. This must be accomp-
lished prior to a dump.
1. At the System transition Unit (STU):
- Assure the system application is disable,
inactive and stopped.
- Set the Panel Lock Switch to the RELEASE
POSITION.
- For the appropriate PROCs, IOUs, and SIU's
in the application; set the Maintenance Mode
switches ON.
2. At the System Maintenance Unit (SMU):
Initial Program Load (IPL) the SMU by de-
pressing STOP, RESET, and SYS LOAD: the SMU
Supervisor will load.
- At the SMU console, depress function key 'F1';
this will load and execute the PANEL program.
Press (MESSAGE WAITING) then keyin 'IP' to
initiate the printer.

- Answer '3' this is the type of output printer
used.
- Keyin 'GETL XX' where 'L30' is a list provided
by the site execute and dump registers.
- Keyin 'STRT' to start the output printer list-
ing of the CPU registers. When the listing is
finished, go to the STU panel. At the STU panel
turn the Application Maintenance Mode Switches
OFF.
A tape PHI requires the mounting of'the boot tape and a scratch
(dump) tape on two available drives. The system obtains instructions
for the dump from the boot tape, causing the contents of main storage,
the DIAG$ file from the boot tape, and the mass storage copy of the
operating system to be copied to the dump tape for later analysis.
A tape P;'? is specified by setting the STU Input/Output Unit (IOU)
panel channels and device select dial to the selected boot type
drive, setting Jump Select 2 on the processor panel, and depress-
ing clear and initial load on the initial load panel.
The operating system displays the message "PANIC DUMP TAKEN'
when the dump is complete. If the message "PANIC DUMP NOT TARN"
appears instead, retry the dump procedure from the beginning.
When the dump is complete the system is then ready to be rebooted
in accordance with boot procedures.
A disk PH') is specified by setting the STU IOU panel channel and
device dials to the applicable disk drive using the DRS pack,
setting Jump Select switch 2 on the processor panel, and depress-
ing clear and initial load on the initial load panel.

The disk PMD obtains instructions for the dump from the Disk
Resident System (DRS) causing the operating system to take a
disk storage. The system will display on the operators console
"PANIC DUMP TAKEN". At this time the operator must manually
initiate a disk or tape boot. (Note: The system does not auto-
matically boot itself). Upon completion of the boot, operators
should start a 'SDUMP'. The following message will print on the
console:
0 ENTER PANIC DUMP TAPE REELNO, EQP OR NO
At this time answer the message with "EQP", the SDUMP will process
until completed.
8. CMS SYSTEM
a. CMS dumps may be taken in two ways to provide diagnostic
information.
1. II CMS TERMS will terminate CMS and produce a dump.
cMS will notify the operator when CMS can be restarted.
2. If OVIS is terminated by the operator with an 'E CMS'
keyin a.dump is available but is not processed. This dump i t %o e.
:}-x.izk with the keyin:
ST CMS7*FILE. CAISDUMP/OPS, , ,UNIVAC
DEV
The 'E CMS' should be used by the operator only as a last
resort, only if (1S cannot be terminated with the II 04S
TERMI keyin.
OvLS only affects Delta Data Terminals and the COINS System,
therefore dumps of 07S should only be initiated due to a
failure of these two device types.

There are several reasons for taking a dump of CIS:
(a) In case of line hangs to Delta Data's
or COINS system which cannot be cleared.
(b) COMPOOL has been reduced to minimal
levels and cannot be recovered.
(c) I I GIS operator keyins (EX:HLD) fail
to function.
(d) A fatal contingency will cause GIS to
terminate on a dump to be processed. This
process requires no operator intervention
and occurs automatically.
9. C/SP SYSTEM
a. C/SP dumps may be taken in three ways each having various
advantages, in providing diagnostic information.
1. Initiated by 'PC I' keyin. This is the preferred
method since it also reloads the C/SP program and re-
initializes the line handlers if taken for a line hang
condition. Since CIS reassigns lines after the RE-IPL,
users,Mperience a short delay of 20-30 seconds in re-
sponse on TIP terminal output and will not have to re-
sign-on.
2. Initiated by 'PC D' keyin. This is similar to the
'DU MP' systems dump in that the C/SP supervisor is not
stopped or RE-IPL'd. The information provided by this
dump is limited in nature because C/SP memory is dynam-
ically changing during the dump process. No outage will
occur to the user.
3. Manual I-IALT,CLR,RUN from C/SP panel. This method
provides the most data but should only be required when
dumps of method 1 fail to provide information necessary
to resolve a problem. This method dumps lower memory
locations that cannot be observed in dumps 1 F, 2. This
results in the longest outage of the three methods un-
less two operators are involved to initiate the dump.

NO. 50- 0003 26 OCTOBER 1982
There are several reasons for taking a C/SP dump.
a. C/SP red light stop. A manual dump should
be taken.
b. 'Program terminated' message on system console.
If an IPL solicit is not received, a 'PC I' keyin
should be made with a 'D' response to the IPL message.
c. Operator cannot clear a Hung Line by DNing and
UPing the line (/DIVN/ACT for CMS) from the system
console. It is recommended that the dump be taken
when the hang re-occurs after a RE-IPL since DNing
and UPing of the line will mask the original cause.
d. Terminal failure to sign-on. Similar to c.
Reload C/SP, wait a reasonable time for sign-on
(15 min for HETRA/9300) and dump if still hung..
Avoid keyins to affected line before dumping.
10. D,MS SYSTEM
a. Dump information on 99S appears in the procedure on I)MS.
11. REQUIREMENTS FOR ANALYSIS (PROCESSING DUMPS)
Vital information is needed by SPS and/or UNIVAC CEs to determine
the cause of a system hang or crash. The availability of this
information will aid and expedite in the correction of the problem
area. The information gathered should be included and/or attached
to the Descrepency Report (DR). Information needed is as follows:
*a.
If one of the Partition Panel check lights on.
1.
Indicate which one
2.
No dump necessary
*b.
If the Processor STOPLIGHT and the Processor active
Light On at the same time.
1. Indicate 'Control Stop'
2. No dump necessary

2. Take a dump
d. The Du;np Tape Number.
e. Hardcopy of Dump if it is first occurrence of problem.
f. Error Code.
g. For Operator Initiated Dumps:
1. Type of Dump Initiated (MANUAL, 150 or 'DUM MP')
2. A statement or reason for system reboot i.e.,;
- system not responding to all or
certain console keyins.
- lost COMPOOL
3. List the actions taken on recovery attempts
prior to reboot.
h. All System Dumps (AUTO RECOVERY)
1. Include a copy of the console sheet from the
slave console with the DR and Dump.
2. Include statements on any and all unusual
activities prior to and during the problem i.e.,;
- Reconfigurations
- Transfer switch activities
- Operator console entries
- User complaints (CMS, RIMS lines)
The operator should use the "DUMP SUPPORTING DATA" stamp, as shown in
Attachment 1, on the DR form. The format summarizes what is required per para-
graph 1.1.
*UNIVAC CE should be notified df items A, B, or C occur.
