IOGEN generates two logs.
The IOGEN log is written to SYSLST. It contains the following information:
List of the input statements. All statements that are read in are logged.
IOCF generation lists
The I/O configuration generated is logged in three tables:The “Physical Channel Listing” contains, for each channel, the generation data and the number of connected controllers and devices.
The “Physical Controller Listing” contains, for each controller, the generation data, the number of connected devices and the channel ports with their connection data.
The “Physical Device Listing” contains, for each device, the generation data and the controller ports with their connection data.
The IOCGEN log contains detailed information on the I/O units generated.
The device table contains – sorted according to the CMPG (in order of ascending CMPG numbers) – generation information on all the devices assigned to the CMPG (in order of ascending subchannel numbers).
Additional information for each controller is output in the controller table.
Output of the IOCGEN log can be controlled using the PROT operand of the CPGOPT statement, see
"CPGOPT - Define generation options for IOGEN".
