OAM schedules AUDIT, REMAP, and EJECT requests. If OAM rejects the requests, or an error occurs during the scheduling of the request, the OAM errors are recorded as ISMF log entries. An example of a rejected request is an ?AUDIT in the LINE OPERATOR column for a specific optical volume. See the feedback area of the ISMF log entry for the return codes and reason codes for OAM errors. The ISMF log entries are in the ISPF Transaction Log.

For the meaning of the OAM return and reason codes, see the z/OS DFSMSdfp Diagnosis.
