The information returned by the EAV migration assistance tracker describes the occurrence of an instance in text. Like the console ID tracking facility, the EAV migration assistance tracker returns tracking information and a tracking value. The tracking information can be from 1 to 28 characters in length and the system can set any EBCDIC value. The tracking value is four bytes of binary data associated with this instance. For DFSMS, these values include data to associate an instance to a specific DFSMS function and to define the reason for the instance being recorded. This standard allows for maximum flexibility in defining exclusion records that apply to DFSMS records.

The conventions for the tracking information and tracking value for a DFSMS instance follow.
