COMPAKTOR MESSAGES (CPKNNNXX) 100.6
CPK518E DSCB AT CCHHR(HEX) -- cccchhhhrr -- INVALID OR UNSUPPORTED DSCB TYPE t
Reason: A DSCB was read and was not a Format 0, 1, 2, 3, 4, 5, 7, 8, or 9 DSCB. COMPAKTOR
does not support Format 6 DSCBs that describe split cylinder data sets, no longer
supported on z/OS.
Action: If Format 6 DSCBs exist, you cannot COMPAKT, MAP, or SIMULATE this volume. You
may want to list the VTOC as described under message CPK516E.
CPK519E
Reason:
Reason:
Action:
DSCB AT CCHHR(HEX) -- cccchhhhrr -- HAS AN INVALID EXTENT ADDRESS addr
-- DATA SET-dsname
One or more extent descriptions in a DSCB are invalid. “cccchhhhrr” is the disk address
of the DSCB (cylinder, track, and record, in hex). “addr” is the invalid extent address,
and “dsname” is the name of the data set associated with this DSCB.
This can occur if:
❖ An extent descriptor is all zeros.
❖ The starting address of the extent is less than the ending address.
❖ For an SUL (standard user label) data set, the first extent is not exactly one (1)
track.
❖ The starting or ending cylinder number is greater than the number of cylinders on
the volume. This may occur if COMPAKTOR cannot properly identify the type or
capacity of the disk.
A DSN IN TRACK nnnnn OF THE VTOC HAS AN INVALID EXTENT
This form of the CPK519E message shows the track number “nn” in the VTOC that
contains invalid DSCB information.
This can occur if:
❖ The number of extents in the Format 1 exceed the actual number of extents.
❖
The Format 3 in the DSCB chain has fewer extents than are defined in the
Format 1.
This is a serious error and should be attended to immediately. Follow procedures
described in Section 40.17 “COMPAKTOR VTOC Errors”.
This error can also occur if the volume has been initialized with an incorrect number of
data cylinders or alternate tracks and the data set is at or near the end of the volume.
If you also receive message CPK512I, correct the error as described under that
message and rerun COMPAKTOR to see if the CPK519E message still occurs.
CPK520W DSCB AT CCHHR(HEX) -- cccchhhhrr -- HAS AN INVALID EXTENT SEQUENCE NO.
Reason: Extents owned by a data set are numbered from 0 to 127, ascending. A violation of this
rule was detected.
Action: See message CPK519E.
