If theRSCS message DMTREX090T PROGRAM CHECK IN SUPERVISOR -- RSCS SHUTDOWN was issued, the program check handler has terminated RSCS due to a
program check interrupt in other than a dispatched line driver. A dump
of virtual storage is automatically taken. A programming error is the
probable cause.
The wait state code is loaded byDMTREX at RSCS termination or
automatically during program check handling.
If neither of the last two messages was issued, use the CPDUMP command to dump the contents of virtual storage. Do an IPL to restart
the system. If the problem persists, notify the system support
personnel.!AI1 STATE A program check interrupt has occurred during
initial processing, before the program check handler could be activated.
This may be caused by a programming error or by an attempt to loadRSCS into an incompatible virtual machine. The latter case can occur if the
virtual machine has (1) an incomplete instruction set, (2) less than
512K of virtual storage, or (3) does not have the requiredVM/370 DIAGNOSE interface support. The wait state code is loaded automatically
during the initial loading and execution of theRSCS supervisor, DMTINI, DMTREX, DMTAXS, or DMTLAX. Verify that the RSCS virtual machine configuration has been correctly
specified and that the "retrieve subsequent file descriptor" function ofDIAGNOSE Code X'14' is supported. Dump the contents of virtual storage
via the CPDUMP command. If the problem persists, notify the
installation support personnel.!AI! CODE An unrecoverable error occurred when reading the RSCS nucleus from DASD storage. This may be caused by a hardware
malfunction of theDASD. It may also be the result of an incorrect
virtualDASD definition, an attempt to use a system residence device
unsupported byRSCS, incorrect RSCS system generation procedures, or the
subsequent overwriting of theRSCS nucleus on the system residence
device. The wait state code is loaded by DMTINI after an attempt,
successful or not, to issue the message:DMTINI402T IPL DEVICE READ I/O ERROR Verify that the RSCS system residence device has been properly
defined as a virtualDASD and that the real DASD is mounted and
operable. If the problem persists, dump virtual storage via the CPDUMP command and notify the installation support personnel. The RSCS system
residence device may have to be restored or theRSCS system may have to
be regenerated.
WheneverRSCS has no task ready for execution, DMTDSP loads a masked-on
wait statePSW with a code of hexadecimal zeros. This occurs during
normalRSCS operation and does not indicate an error condition. An
external interrupt due tocommand entry or an I/O interrupt due to the
arrival of files automatically resumes processing.
