Privilege Class: G
Use SET SVC76 to specify whether the control program (CP) or your virtual
machine will handle the SVC76 instruction.
SVC76 CP
SVC76 VM
controls whether SVC76 instructions issued by your virtual machine are
processed by CP for recording of virtual device errors. Specify CP if guest error
records are to be recorded by CP when your virtual machine is running in
supervisor state. Specify VM if you do not want errors recorded and if you want
all guest SVC76 operations to be processed by your virtual machine. At logon,
SVC76 is set to VM if the SVC76VM parameter is specified in the OPTION
control statement, or to CP if the SVC76VM parameter is not specified in the
OPTION control statement.
1. If your virtual machine has SET SVC76 set to CP, and does one of the
following:
v Issues an SVC76 from problem state
v Uses a not valid SVC76 interface
v Presents an unrecognizable EREP record
v Presents an EREP record that cannot be translated,
the SVC76 is reflected to the user.
2. Unless you are intentionally simulating hardware errors in your virtual machine
(for example, in order to test error recovery procedures), you should let CP
record all errors. When CP maintains the hardware error log, your installation
has the most accurate information about equipment errors.
