MODE command

Use the MODE command to control the actions of recovery management when certain types of machine check interruptions occur. The actions you can control are:

The recording/monitoring status for each type of machine check interruption controlled by the MODE command. For the procedure to print the logrec data set, see the EREP User's Guide and the EREP Reference
The monitoring of hard machine checks, including machine checks that indicate timing facility damage
The suppressing of system recovery or degradation machine-check interruptions

Table 1 summarizes the information that the MODE command provides.

Table 1. Summary of the MODE Command
Command:	Topic:
MODE AD MODE CC MODE CO MODE CS MODE IC MODE IV MODE PD MODE PS MODE PT MODE SC MODE SD MODE SL MODE SS MODE TC	Controlling the recording of hard machine check interruptions
MODE DG MODE SR	Controlling the recording of system recovery and degradation machine check interruptions
MODE STATUS	Displaying recording and monitoring status

Note:

When PROCVIEW CORE is in effect, the MODE commands AD, CC, IV, PD, PS, PT, SD, SL, and TC operate with RECORD=ALL,CPU=ALL. When PROCVIEW core is in effect, these MODE commands can no longer specify a machine check threshold. End of change

You can enter the MODE command any number of times for any processor. Issuing the MODE command for a particular type of machine check changes only the recording or monitoring mode for that type of machine check, and changes it only for the processor(s) specified (or for all processors if no particular processor is specified). To change the recording or monitoring mode for several types of machine checks, you must enter a series of MODE commands. Each such MODE command specifies one type of machine check and the desired recording or monitoring mode for that type of machine check. If you issue the MODE command more than once for the same type of machine check, the last command (most recent) supersedes the previous commands.
