Hercules Version 3: System Messages: CU - CCKD Utilities

Messages issued by the cckd utility commands (cckdcdsk, cckdcomp and cckdswap) and cckd utility functions (cckd_chkdsk, cckd_comp and cckd_swap) are described here. The utility functions are called by both the utility commands and Hercules.

Messages

Messages are in the format
HHCCUnnnt file message text
where nnn is the message number, t is either I, W or E, depending on the severity of the message. file will either be the part of the file name following the last slash (/ or \) when called by a utility command, or will be xxxx: file[n] where xxxx is the device number and n is the shadow file number when called by Hercules.

The file portion of the message is omitted below for brevity.

HHCCU101I converting to endian-format
Meaning
The file is in the wrong endian (byte order) format for the host architecture. The file is being converted to the host endian format endian-format.

HHCCU501W recovery not completed, missing compression
Meaning
Phase 3 recovery did not complete because one or more trk or blkgrp images were compressed using a compression (zlib or bzip2) that was not built into Hercules
Action
Processing terminates. The file has not been updated. Build Hercules with the missing compression libraries.
Issued by
cckdutil.c function cckd_comp
HHCCU502W free space not rebuilt, file opened read-only
Meaning
Free space errors were detected but the free space was not rebuilt because the file is not opened for write

Omit the -ro option for cckdcdsk, or change the file permissions to enable the file to be opened for read-write for Hercules
Issued by
cckdutil.c function cckd_comp
HHCCU600W forcing check level level[; reason]

Action
At a minimum, free space will be rebuilt
Issued by
cckdutil.c function cckd_comp
HHCCU601W cdevhdr inconsistencies found code=code
Meaning
The space statistics in the cckddasd device header (cdevhdr) contain inconsistencies described by code. code is a 16-bit bit field and more than one bit may be on. See cckdutil.c for the different bit settings.

%s offset 0x%" I32_FMT "x len %d is out of bounds
HHCCU602W space offset offset len length is out of bounds
Meaning
The space space (trk, blkgrp or l2) either precedes the end of the L1 table (at the beginning of the file) or exceeds the end of the file
Action

Issued by
cckdutil.c function cckd_comp
HHCCU603W space1 offset offset1 len length overlaps space2 offset offset2

Issued by
cckdutil.c function cckd_comp
HHCCU604W space l2 inconsistency: len length, size size

Issued by
cckdutil.c function cckd_comp
HHCCU620W space[id] hdr error offset offset: xxxxxxxxxx
Meaning
A header error was found for space (trk or blkgrp) during validation. id is the trk or blkgrp number. The header is located at file offset offset. The contents of the 5 byte header is xxxxxxxxxx in hex.

The first byte of the header should be either 00 (compress none), 01 (compress zlib) or 02 (compress bzip2).
For ckd, the next two bytes is the cylinder (in big-endian byte order) and the two bytes after that is the head (also in big-endian byte order).
For fba, the next four bytes is the block group number (in big-endian byte order).

The header contains an invalid value. Either the offset is incorrect or the header has been overlaid.

Action
The space will be recovered
Issued by
cckdutil.c function cckd_comp
HHCCU621W space[id] compressed using compression, not supported
Meaning
During validation, the header for space (trk or blkgrp) indicates that the space was compressed using compression (zlib or bzip2) but support for that compression method was not built into Hercules. id is the trk or blkgrp number.
Action
Processing continues. However, no recovery will take place.
Build Hercules with the specified compression library.
Issued by
cckdutil.c function cckd_comp
HHCCU622W space[id] offset offset len length validation error
Meaning
The space (trk or blkgrp) at offset offset and length length failed validation. id is the trk or blkgrp number. Either the space did not uncompress successfully or the uncompressed space contains some kind of error. This error is detected during check level 3 validation.
Action
The space will be recovered
Issued by
cckdutil.c function cckd_comp
