STSI 1.2.2 fields
Offsets
Dec Hex Type Len Name (Dim) Description
56 38 Unsigned 4 SYTSYG_SCPCAPAB The capability of a secondary
CPU in the configuration
60 3C Unsigned 4 SYTSYG_CPUCAPAB Specifies the capability of
one of the CPUs in the current
configuration. Used as an
indication of the capability of
the CPU relative to the
capability of other CPU models.
This value applies to each of
the CPUs in this configuration.
64 40 Unsigned 2 SYTSYG_CPUCOUNT The Total number of CPUs in
the configuration. Includes all
CPUs in the configured,
standby, andthe reserved state.
66 42 Unsigned 2 SYTSYG_CPUCFGCT Specifies the number of CPUs
in the configured state. A CPU
is in the configured state when
it is in the configuration and
available to be used to execute
programs.
68 44 Unsigned 2 SYTSYG_CPUSTNBY Specifies the number of CPUs
in the standby state. A CPU is
in the standby state when it is
in the configuration, is not
available to be used to execute
programs, and can be made
available by issuing
instructions to place it in the
configured state.
70 46 Unsigned 2 SYTSYG_CPURESVD Specifies the number of CPUs
in the reserved state. A CPU is
in the reserved state when it
is in the configuration, is not
available to be used to execute
programs, and cannot be made
available by issuing
instructions to place it in the
configured state.
***********************
STSI 3.2.2 fields This information is level-3 from a VMDBK if available.
Offsets
Dec Hex Type Len Name (Dim) Description
72 48 Unsigned 1 SYTSYG_VL3DBCT Specifies the number of VM
levels running between the
level at which this data was
collected and the hardware. For
example, data collected from a
VM system running second level
would show a value of 1. A
third level system would show a
value of 2.
73 49 Character 1 * Reserved and available for
IBM use.
74 4A Unsigned 2 SYTSYG_VL3COUNT The Total number of Logical
CPUs that are provided for this
level-3 configuration. Includes
all of the logical CPUs that
are in the configured, standby,
and the reserved state.
76 4C Unsigned 2 SYTSYG_VL3CFGCT Specifies the number of
logical CPUs for this level-3
configuration that are in the
configured state. A logical CPU
is in the configured state when
it is in the level-3
configuration and available to
be used to execute programs.
78 4E Unsigned 2 SYTSYG_VL3STNBY Specifies the number of
logical CPUs for this level-3
configuration that are in the
standby state. A logical CPU is
in the standby state when it is
in the level-3 configuration,
is not available to be used to
execute programs, and can be
made available by issuing
instructions to place it in the
configured state.
80 50 Unsigned 2 SYTSYG_VL3RESVD Specifies the number of
logical CPUs for this level-3
configuration that are in the
reserved state. A logical CPU
is in the reserved state when
it is in the level-3
configuration, is not available
to be used to execute programs,
and cannot be made available by
issuing instructions to place
it in the configured state.
82 52 Character 2 * Reserved and available for
IBM use.
84 54 Character 8 SYTSYG_VL3MNAME Specifies the name of this
level-3 configuration.
92 5C Unsigned 4 SYTSYG_VL3CAF The Capabiltiy Adjustment
Factor specifies the amount of
the underlying level-1, level-2
or level-3 configuration
capability that is allowed to
be used for this level-3
configuration by the virtual
machine control program. The
maximum value is 1000, and the
fraction of level-3
configuration capability is
determined by dividing the CAF
value by 1000.
96 60 Character 16 SYTSYG_VL3CPNAM Identifies the virtual
machine control program that
provides this level-3
configuration. This may include
qualifiers such as version
number and release level.
112 70 Unsigned 4 SYTSYG_MAI_MISS Count of Missing Adapter
Interruptions
116 74 Unsigned 4 SYTSYG_MAI_UREC Count of unrecoverable
Adapter Interruptions
120 78 Unsigned 4 SYTSYG_NCPCAPAB The nominal capability of a
CPU in the configuration
