Modifying Input/Output (I/O) Configurations
Using the SYSGEN I/O Configurator
NO PENDING SYSGEN CONFIG CHANGES
The DOIONOW command creates a log file, ONLNOLOG.PUB.SYS, which is used to record
the commands executed by IOCONFIG. If the DOIONOW command generates an error, you
may view this same log file to determine the cause. This log file is purged and a new one is
created prior to invoking the new configuration, which means that it only contains
information for the last execution of IOCONFIG. Once you have found the problem, you
can then edit the input file for the DOIONOW command, LOG4ONLN.PUB.SYS, to avoid
duplicating the events that created the error.
