Allan,
   
  I tried your suggestion (shuttdown the STC )  retried the recycle and it 
worked.  Thanks.

In my experience there are usually 2 root causes for this.
1) The tape has been partially written over.
2) IO error on tape.

Corrective actions (in order of preference:

1) Sometimes, HSM does get confused. Bounce DFHSM and retry.

In case (2) delete the offending file (the one with with the IO error)
and retry. This file is normally the file immediately before the 1st
RC=68. i.e. 
Single file delete and recovery.

In case (1) an HSM audit to identify the possible datasets and update
the CDS. In an extreme case, DELVOL PURGE will be required. This will
clean up the CDS of all files that HSM thinks are on that volume.

HTH,

ARC0440I/ARC0734I - Problem

2007-10-29 Thread John Dawes
DFHSM was attempting to recycle the tape.  Several messages were displayed 
ARC0440I - VOLUME 032009 CONTAINS AN INVALID CDD OR A  TAPE POSITIONING ERROR 
HAS OCCURRED. ARC0734I ACTION=RECYCLE FRVOL=032009 TOVOL=** BLOCKS= 1 
RC=  68, REASON=
 DSN=HSM.HMIG.V143501.Y321.OMMD0$02.J7287
 
  How can I know what the real problem is - invalid CDD or TAPE POSITIONING 
error?  Any hints?  In this partition DFHSM is in simplex state.
   
  Thanks
