configuration.
144 90 Character 4 MTRSYS_SYSMPOM Identifies the Plant of
manufacture for the configuration.
STSI 2.2.2 fields Obtain STSI level-2 data when available. This
configuration data will indicate the configuration information for an
LPAR when available otherwise it will remain as default binary 0 values.
Offsets
Dec Hex Type Len Name (Dim) Description
148 94 Unsigned 2 MTRSYS_LPNUMBER LPAR Number of the level-2
configuration. This number is
unique to this configuration from
all other level-2 configurations
provided by the same LPAR
hypervisor.
150 96 Bitstring 1 MTRSYS_CPUCHAR Describes the characteristics of
the logical CPUs that are provided
for the level-2 configuration.
151 97 Bitstring 1 * RESERVED and available for use
152 98 Unsigned 2 MTRSYS_CPUCOUNT Specifies the total number of
logical CPUs that are provided for
this level-2 configuration. This
number includes all of the logical
CPUs that are in the configured
state, the standby state, or the
reserved state.
154 9A Unsigned 2 MTRSYS_CPUCFGCT Specifies the number of logical
CPUs for this level-2
configuration that are in the
configured state.
156 9C Unsigned 2 MTRSYS_CPUSTNBY Specifies the number of logical
CPU's for this level-2
configuration that are in the
standby state. A logical CPU is in
the standby state when it is in
the level-2 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.
158 9E Unsigned 2 MTRSYS_CPURESVD Specifies the number of logical
CPU's for this level-2
configuration that are in the
reserved state. A logical CPU is
in the reserved state when it is
in the level-2 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.
160 A0 Character 8 MTRSYS_LPARNAME Specified the name of this
level-2 configuration.
168 A8 Unsigned 4 MTRSYS_LPARCAF The LPAR Capabiltiy Adjustment
Factor specifies the amount of the
underlying level-1 configuration
capability that is allowed to be
used for this level-2
configuration by the LPAR
hypervisor. The maximum value is
1000, and the fraction of level-1
configuration capability is
determined by dividing the CAF
value by 1000.
172 AC Unsigned 2 MTRSYS_CPUDEDCT Specifies the number of
configured state logical CPUs for
this level-2 configuration that
are provided using dedicated
level-1 CPUs
174 AE Unsigned 2 MTRSYS_CPUSHARD Specifies the number of
configured state logical CPUs for
this level-2 configuration that
are provided using shared level-1
CPUs.
