Note: STIDP is provided for purposes of backward compatibility. IBM highly
recommends that the Store System Information instruction (STSI) be used
rather than STIDP. STSI is the preferred means to obtain all CPU information
including machine serial number. When a unique logical CPU address is all
that is required, use the Store CPU Address (STAP) instruction.
Examples of CPU ID Information
The following examples show the format and contents of the CPU ID information
stored by the STIDP instruction for logical CPs in active LPs.
Table 1-1 shows the CPU ID information for a z9 EC with 3 active LPs.
