Explanation
An unusual condition was encountered in the system
routines that update the VTOC on device
ddd, volume
ser,
which caused the DIRF bit to be set to one, or caused active VTOC
recording facility (VRF) data to be left in the VTOC index map, indicating
that the VTOC may contain errors:
- Cde 0
- An I/O or unexpected CVAF error return code error occurred in
the DADSM routines Allocate, Extend, Scratch or Partial Release. The
routine ended processing, thereby leaving the VTOC in a partially
updated state.
- Cde 4
- The Scratch or Partial Release function of DADSM discovered that
the space it was returning to the chain of Format-5 DSCBs which describe
the free space on the volume was already present in a format-5 DSCB.
Although Scratch or Partial Release was able to successfully process
this incorrect data, thereby correcting the situation, other problems
may exist on the VTOC.
- Cde 8
- An I/O error or unexpected CVAF error return code occurred in
the DADSM routines (Allocate, Extend, Scratch, Partial Release, Rename)
during updating of the VTOC index or the VTOC on an indexed VTOC volume,
thereby leaving the indexed VTOC in a partially updated state. DADSM
processing is ended.
There is only one decimal reason code
rsnc associated
with message IEC603I.
- 027
- The index data set is full.
In the message text:
- dev
- The device number of the specified device.
- ser
- The volume serial number.
- cde
- The code.
- rsnc
- The reason code.
System action
For codes 0 and 8, if the error occurred during
allocation, the job is ended. If the error occurred in the middle
of a job extending the space allocated to a data set, or a job releasing
unused allocated space while closing a data set, the job is abnormally
ended. If the error occurred while scratching or renaming a data
set, an I/O error is returned. For code 0 the DIRF bit in the format-4
DSCB is set to one; for code 8 the VRF data set is left in the VTOC
index map to indicate that Active VTOC Recording Facility (VTOC) may
be in error. A system dump is taken if the cause of the error is an
unexpected CVAF error return code.
If code is 4, VTOC updating
continues, and if no further errors are encountered, the job continues
processing.
The DIRF bit in the format-4 DSCB is set to one.
Operator response
Report this message to the system programmer.
For
error code 0 or 4, either message IEC602I or message IEC604I will
be issued the next time allocation is attempted on this volume. For
code 8, which refers to an indexed VTOC, message IEC605I will be issued
when the next DADSM VTOC updating function (Allocate, Extend, Scratch,
Partial Release, Rename) is performed.
System programmer response
If the error recurs and the program
is not in error, look at the messages in the job log for more information.
Search problem reporting data bases for a fix for the problem. If
no fix exists, contact the IBM® Support
Center. Provide the SYSOUT output for the job.
Programmer response
Some attempt should be made to analyze the
state of the VTOC on the affected volume.
