April 1, 1981 HOW TO PRINT A C8S DU!P PILE Use the V8FDU8P co •• and to print a previously created dump file under C8S by enterinq: VMFDU8P PRBnnnnn [options]
at the terminal. The .essage: PRINTING FILE 'PRBnnnnn Dnn DU8P' then occurs at the ter.inal. When the specified file has been formatted
and printed, one of two cOBpletion messages is displayed: DUMP FILE 'PRBnnnnn Dnn DUMP' PRINTED AND KEPT
-- or -- DUMP FILE 'PRBnnnnn Dnn DUMP' PRINTED AND ERASED HOW TO PRINT A CP ABEND DU!P FR08 TAPE When the CP abend du.p is set to a tape, the records are 132 characters
long, unblocked, with a hlocksize of 132 and carriage control
characters.
If the CP dump unit has been specified as a tape drive, and one or
more dumps have been placed on the tape, use the following procedure to
print the dumps.
1. Log on to the V"/370 system with any userid that has the capability
of running C"S. No other special privilege classes or options are
required.
2. Attach a tape drive to the virtual machine as address Mount the tape containing the CP abend dumps. q. IPL the C!S system and perform the usual access requirements.
5. Issue the following C!S commands:
FILEDEF ddname1 PRINTER (RECF" UA LRECL 132)
FILEDEF ddname2 TAP1 (9track DEN nnnn RECF" U LRECL 132) KOVE ddname2 ddname1
cp close prt
step 5 can be repeated for as many dumps as are on the tape. Note
that the CP dump routines write two tape marks at the end of each file.
Therefore, to process the next dump. the TAPE FSF command line must be
issued to position the tape for reading the next dump file.

Page of GC20-1806-9 As Updated April 1, 1981 by TNL GN25-0834 NETWORK DUMP OPERATIONS If 3704/3705 operations are erratic, fatal hardware errors occur, or
some other internal error appears, the Communications Controller's
storage should be dumped. The NETWORK DUMP command dumps the contents
of 3704/3705 storaqe for EP 3704/3705 control programs, if unit check or IPL required conditions are detected.
The format of the command with the DUMP operand is:
r------------------------------------------------------------------------- I I NETWORK I I , r , DUMP raddr fAUTO I 10FF I L L- _____ _
raddr IMMED AUTO OFF is the real hexadecimal address of the 3704/3705.
is the default operand; it forces an immediate dump. The IMMED operand, if specified, does not reload the control
program. Before 3704/3705 resources can be used again, the
control program must be reloaded. To reload the control
program after the "NETWORK DUMP raddr IftftED" command has
executed, use the "NETWORK LOAD raddr ncpname" command.
If the IMMED operand is specified, a check is made to
determine whether the "IPL required" sense status is present.
If it is not, the following message occurs:
DMKNET461R CTLR raddr IPL NOT REQUIRED; ENTER YES TO CONTINUE: This pause in operations allows the operator an opportunity to
check the NETWORK DUMP command line before engaging or
terminating the operation.
causes a dump if VM/370 subsequently detects a unit check
condition or "IPL required" condition. If AUTO is specified,
each time a dump is taken, the Communications Controller is
reloaded with the 3704/3705 control program that was
previously active.
resets a previously set AUTO (automatic dump) status.
Note: The dumps produced by the NETWORK command cannot be processed by
the VKFDUMP service program. NETWORK-initiated dumps are processed by
the NCPDUMP (Network Control Program DUMP) service program created for
this task.
