IBM Tivoli Storage Manager V6.3 Fix Pack 5 (6.3.5.000) Server Downloads

APAR status

• Closed as program error.

Error description

• PLATFORMS AFFECTED: ALL
  VERSIONS AFFECTED: 6.1, 6.2, 6.3
  USERS AFFECTED: ALL TIVOLI STORAGE MANAGER SERVER USERS OF
  DEDUPLICATION
  
  In cases where data which initially exists in a deduplicated
  pool, is moved out of that pool to another pool (deduped or not)
  and then is moved back into the original pool using MOVE
  NODEDATA, invalidated links may result.
  
  The invalidated links will surface after
  
  MOVE NODEDATA has been issued and the data is accessed again. If
  the invalidated links have not been repaired, or re-linked, they
  will be marked as damaged once accessed again.
  Once the invalidated extents have been marked as damaged, any
  attempt to access these files will result in a damaged indicator
  message and failure to either move, copy or retrieve the files.
  
  Customer/L2 Diagnostics
  -----------------------
  If the data movement scenario, as described above, has been
  encountered, the VALIDATE EXTENTS utility can be used
  to proactively check for invalidated links. This utility will
  check for damaged or invalidated links, and if found, will mark
  the file(s)as damaged such that they can be restored from an
  available copy pool.
  
  
  VALIDATE EXTENTS <DEDUP POOL> ACTION=MARKDAMAGED
  
  NOTE: The trigger and symptom for this APAR is related to
  IC90390.
  It is also similar to IC82573 although the root cause is not
  related
