Hallo Systemer,
vielleicht hilft Dir dies noch:

MSD Problem Diagnosis
The most important element of problem diagnosis when a MSD is taken is the data displayed on the MSD Manager. This data is the system reference codes, listed as words 1-9. Based on the first (left hand) digits of word 1, the problem can be classified as hardware, System Licensed Internal Code, OS/400, or an attention signal. This information is needed to engage correct support teams. See the associated SRC contact table to aid in contacting the correct support team.

Note : When the MSD Manager screen appears, failure to copy the MSD often limits supports ability to diagnose the problem. If the MSD is not going to be copied, it is very strongly recommended that all system reference codes be copied down from the MSD Manager screen before the system is IPLed.
