Doing a CA Datacom DBUTLTY EXTEND is getting the following errors:
IEC145I 413-1C,IFG0193A,jobname,stepname,ddname,device,volser,dsn DB02405I - PXX START jobname nnnnn 13(005) XXXXB-nnn- D-1 DBUTLTY EXTEND DB02406I - PXX END - INVALID DASD TRACK OUTSIDE EXTENTS IEF450I jobname stepname - ABEND=S000 U0004 REASON=00000000 159
A second EXTEND, an EXTRACT or any attempt to open the file gets error:
DB02405I - PXX START jobname nnnnn 76(009) OPEN -nnn- D-1 DBUTLTY EXTEND DB02406I - PXX END - OPEN, NOT ENOUGH TRACKS DB00501E - OPEN ERROR - RETURN CODE 76 (009) CXX=xxxxxx nnnnnn
This was found not to be a Datacom issue.
The problem is due to a z/OS problem with managing the VTOC. Currently there is no IBM PTF to fix the problem. It causes the last volume of a multi-volume dataset to have a VTOC entry that does not have the "last volume" bit set on.
