MESSAGES AND CODES<br />

COMPAKTOR MESSAGES (CPKNNNXX) 100.6<br />

CPK518E DSCB AT CCHHR(HEX) -- cccchhhhrr -- INVALID OR UNSUPPORTED DSCB TYPE t<br />

Reason: A DSCB was read and was not a Format 0, 1, 2, 3, 4, 5, 7, 8, or 9 DSCB. COMPAKTOR<br />

does not support Format 6 DSCBs that describe split cylinder data sets, no longer<br />

supported on z/OS.<br />

Action: If Format 6 DSCBs exist, you cannot COMPAKT, MAP, or SIMULATE this volume. You<br />

may want to list the VTOC as described under message CPK516E.<br />

CPK519E<br />

Reason:<br />

Reason:<br />

Action:<br />

DSCB AT CCHHR(HEX) -- cccchhhhrr -- HAS AN INVALID EXTENT ADDRESS addr<br />

-- DATA SET-dsname<br />

One or more extent descriptions in a DSCB are invalid. “cccchhhhrr” is the disk address<br />

of the DSCB (cylinder, track, and record, in hex). “addr” is the invalid extent address,<br />

and “dsname” is the name of the data set associated with this DSCB.<br />

This can occur if:<br />

❖ An extent descriptor is all zeros.<br />

❖ The starting address of the extent is less than the ending address.<br />

❖ For an SUL (standard user label) data set, the first extent is not exactly one (1)<br />

track.<br />

❖ The starting or ending cylinder number is greater than the number of cylinders on<br />

the volume. This may occur if COMPAKTOR cannot properly identify the type or<br />

capacity of the disk.<br />

A DSN IN TRACK nnnnn OF THE VTOC HAS AN INVALID EXTENT<br />

This form of the CPK519E message shows the track number “nn” in the VTOC that<br />

contains invalid DSCB information.<br />

This can occur if:<br />

❖ The number of extents in the Format 1 exceed the actual number of extents.<br />

❖<br />

The Format 3 in the DSCB chain has fewer extents than are defined in the<br />

Format 1.<br />

This is a serious error and should be attended to immediately. Follow procedures<br />

described in Section 40.17 “COMPAKTOR VTOC Errors”.<br />

This error can also occur if the volume has been initialized with an incorrect number of<br />

data cylinders or alternate tracks and the data set is at or near the end of the volume.<br />

If you also receive message CPK512I, correct the error as described under that<br />

message and rerun COMPAKTOR to see if the CPK519E message still occurs.<br />

CPK520W DSCB AT CCHHR(HEX) -- cccchhhhrr -- HAS AN INVALID EXTENT SEQUENCE NO.<br />

Reason: Extents owned by a data set are numbered from 0 to 127, ascending. A violation of this<br />

rule was detected.<br />

Action: See message CPK519E.<br />
