MESSAGES
FDR175
390.3
PRINT UNIT=uuuu CYL.ccccc TRK.tt REC.rrr KL.kl DL.dl DATA=data
Reason: A PRINT statement was used with FDRERASE, which requests that information about
the contents of tracks be printed from an offline or online DASD. One FDR175
message is printed for each record on the selected tracks. However, if
ERASEDATA=NONE was specified, only Record 0 (R0) is printed for each track, to
reduce the size of the printout.
The cylinder (ccccc), track (tt), and record number (rrr) are displayed, along with the key
length (kl) and data length (dl) of the record; all values are in decimal. “data” is the first
and last eight bytes of the record, in hexadecimal plus the first eight bytes in EBCDIC.
If all data bytes in the record are the same, the last eight hex bytes are replaced with
the text “ALL BYTES THE SAME”; this is the expected result if you have used the
ERASE or SECUREERASE function to erase a DASD unless ERASEPATTERN=FE
was used (for SECUREERASE or ERASE with ERASEPASS, the results of the last
pass are shown). If “END OF FILE” is displayed, then the printed record is an EOF (a
record with a data length of 0).
Every track has a record 0 (R0), so at least one line is printed per track. If there are no
other records on the track, the text “NO RECORDS ON TRACK” appears to the right
of the eight-byte data field of R0. If there are other records on the track “nn
RECORDS ON TRACK” is displayed on the R0 line. After an ERASE or
SECUREERASE function, you see one record on the track.
FDR177
VERIFY CHECKED UNIT=uuuu AND ALL TRACKS CONTAINED ERASE DATA
PATTERN=xx
Reason: A VERIFY function was executed on DASD “uuuu” and all selected tracks contained
data written by FDRERASE. “xx” is a single hexadecimal byte if all bytes in all records
contained that byte. It is “FE (Random)” if the tracks contained the random pattern
generated by ERASEPATTERN=FE. If the DASD was erased using multiple passes
(such as SECUREERASE), the displayed pattern is the last one used.
VERIFY CHECKED UNIT=uuuu AND ALL TRACKS CONTAINED NO RECORDS
PATTERN=ERASE
Reason: In this form of the FDR177 message, a VERIFY function was executed on DASD “uuuu”
and all selected tracks were empty (containing no records).
VERIFY CHECKED UNIT=uuuu AND ALL TRACKS DID NOT CONTAIN ERASE DATA
Reason: In this form of the FDR177 message, a VERIFY function was executed on DASD “uuuu”
and one or more selected tracks contained records that were not written by
FDRERASE. This may mean that the DASD was not erased, or the erase failed.
This can also occur if the CHANGEVOL operand was specified on the MOUNT statement.
The CHANGEVOL operand places a volume serial number in CYL 0 and this causes the
VERIFY function to not have erase data in that location causing this message to be
printed.
Action: FDR175 messages are issued for each non-erased track to indicate its contents. If more
than ERASENUMB= tracks fail verification, the VERIFY function terminates on this
volume. The step terminates with a non-zero return code.
FDR181
MOVE REQUEST ALREADY ON NVOL=volser DSN=dsname
Reason: An FDRMOVE request found that a selected data set was already on a volume in the
NVOL= list, so the data set is not moved.
MOVE REQUEST HAS YET TO MOVE VOL=volser DSN=dsname
Reason: In this form of the FDR181 message, the specified data set has not yet been moved.
