MESSAGES AND CODES
MESSAGES FROM FDR, DSF, AND ABR (FDRNNN) 100.3
Action:
3 – The number of bytes on this cylinder and head exceeds the maximum set by
FDR. If it does not exceed the FDR maximum buffer size FDR processes this
track. Warning: This track may cause an I/O error when reading the
data or the track may not be restorable. If the number of bytes exceeds
the buffer size, the entire cylinder is bypassed.
4 – The count field is out of sequence. The count field encountered has a head
number lower than the previous count field. FDR processes this record as if
it was the next sequential record. This track may not be correctly dumped.
5 – The length of the count fields on this track developed into a negative
number. FDR terminates immediately with an U0300 ABEND.
6 – The track number on one or more count fields was higher than the
maximum number of tracks per cylinder for this device (usually 15). FDR
bypasses the records from the point of error to the end of the cylinder. The
track number in the message has no significance.
7 – The count field has an incorrect cylinder and track number using BUFNO=MAX.
Since this may be a normal condition (such as on VM volumes), this reason is
printed only if you specify PRINT=ALL on the DUMP statement.
8 – The data read from this track appears to exceed the capacity of the track. The
data read is still dumped. This track may cause an error when restored.
An FDR mini-dump is printed. The unlabeled block of storage at the end of the minidump
contains the count fields read. Each count is 8 bytes (2 words) long and
consists of the CC (cylinder), HH (head), R (record), K (key length) and DD (data
length). The count field causing the error is usually the first one on the third line of
counts. Contact INNOVATION DATA PROCESSING for assistance.
FDR124 FORMAT 4 ERROR REASON= reason - id
Reason: FDR detected a problem with the Format 4 DSCB on a volume. The Format 4 DSCB
describes the VTOC itself. The VTOC may be improperly formatted. “reason” is a
reason code, possibly with explanatory text; “id” is the DSCB count field.
The reason code “n” may be:
1 – More than one Format 4 DSCB was found, or the first DSCB in the VTOC
was not a Format 4. This may be due to an IBM problem.
2 – FDR found that the Format 4 contained zero free DSCBs, plus the VTOC high
water mark was set to the first Format 5 DSCB. This is the condition CPK would
leave the volume in if an ABEND or system crash occurred during the restore
phase. This volume may be partially restored. This is a serious problem. The
volume should be placed offline until the error is corrected. If you must
dump the volume, specify PROT=NONE on the DUMP statement.
3 – Label track is invalid. The label track (cylinder 0 track 0) does not contain a
properly formatted volume label.
4 – VOL SIZE < DEVICE SIZE – The number of cylinders in the VTOC is less
than the actual number of cylinders on the device.
6 – TOO MANY VTOC ENTRIES – ABR found too many VTOC entries on this
volume and an internal table was exceeded. An U0103 ABEND follows.
Contact INNOVATION DATA PROCESSING for an override.
8 – An unknown DSCB type was found.
