Procedure

Locate in the dump obtained earlier the media manager process block (MMPB). The MMPB is near the beginning of the summary dump, and the acronym MMPB in EBCDIC representation is at offset 0 of the MMPB. See the sample media manager dump in Media Manager diagnostic aids.
Use the 1-byte MMPMODID field at offset X'1C' in the MMPB to identify the media manager module in control when the failure occurred. The code values in the field are the same as the values in the ff field of the media manager return codes, listed in Media Manager return codes.
Example: If the MMPMODID field value is 05, specify the module keyword as:
```
ICYCCHHR
```
See Modifier keywords.
