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 Character 0 SYTSYG_END
