Error recording on the logrec data set

Table 1 lists the incidents and the types of records that can be recorded on the logrec data set for each incident. The following notes describe how to read the figure.

Note:

When indicated, the notes (A through M) at the end of the figure give more information on the record types specified for the incident.
Reading horizontally, the numbers in Table 1 indicate the approximate chronological creation of the record types that can be recorded for each incident. For example, a permanent channel control check incident generates SLH records (Note A) before generating a long OBR record (Note B).
An asterisk (*) denotes mutually exclusive, device-dependent records. For example, an EOV request on an IBM® magnetic tape drive (3420, 3422, 3430) generates a long OBR record (Note D). The MDR record is ignored (Note E).

See the recording logrec error records chapter of z/OS MVS Diagnosis: Tools and Service Aids for information about initializing the logrec data set.

Note: (letters in parentheses indicate the following):

A: Created one SLH record for each ERP retry attempt for same incident before considering error to be permanent.
B: Created only if condition is permanent (uncorrectable).
C: Created only for devices with a buffered log and removable disk packs (such as the IBM 3330, 3340, 3344, and 3850).
D: Created only for the IBM magnetic tape drives (3420, 3422, 3430). For EOD command, created randomly and can precede short OBR records or follow MDR records.
E: Created only for devices with buffered logs (such as the IBM 3330, 3340, 3344, 3350, 3375, 3380, and 3850). For EOD command, created randomly and can precede or follow short and long OBR records.
F: Not created for teleprocessing devices other than the local 3704/3705 and 3791.
G: Created only for those devices having an ERP that records certain intermittent or permanent incidents (such as the ERPs for the IBM 3330, 3340, 3344, 3350, 3375, 3380, and 3850).
H: Created randomly; MDR and long OBR records can precede short OBR records.
I: Created only for hard machine failures which indicate recording on the logrec data set.
J: Although lost records are reported in a software record, the records lost may be software or hardware records or both.
K: Created to report servicing needs for any I/O device that supports service information message (A3).
L: Created for ETR incidents (port changes, failures).
M: Created for serial link incidents (degradation, failure).
