SMF Operator Prompt Parameter

The PROMPT parameter may be specified in the SMFPRMxx member of SYS1.PARMLIB. If coded with option IPLR or ALL, it will make the system issue a message to the operator when an IPL occurs. The message, IEE956A, prompts the operator to reply with the time of the system failure, the operator's name, and the reason for the IPL. The operator's responses will be recorded in SMF record type 90 subtype 8. To assure that record type 90 is collected at your site, make sure that it is specified in the TYPE option of the SYS parameter as described in the SMF Record Type Specification and SMF Record Subtype Specification sections.

Examples of how to use the PROMPT parameter may be found in the System Management Facilities (SMF) manual for the MVS version running at your site.
Invoking operator prompt and using structured reason codes to describe why the IPL occurred is an excellent way to track system failures over time.
A list of suggested system failure reason codes is given in the SMF Operations Information Area section.
