IT01230: SELECT FROM OCCUPANCY ON 7.1 SERVER MAY DISPLAY RESULTS WITH FILESPACE NAME AND/OR NODE NAME OF "DELETED" WHEN DEDUP'D DATA

IBM Tivoli Storage Manager V7.1 Fix Pack 1 (7.1.1.000) Server Downloads

APAR status

• Closed as documentation error.

Error description

• If a filespace containing data from a deduplicated storage pool
  is deleted, there is the potential for some of the data to be
  base chunks for deduplicated chunks that still resides in other
  filespaces on the server. Because these base chunks must remain
  on the server select from occupancy output still sees them.
  However because no filespace exists that owns them from the
  original client perspective the output from the select will show
  "DELETED" as the filespace name. If the node this data belonged
  to was also deleted then the node name in the select occupancy
  output will also show "DELETED". Use of this "DELETED" value for
  filespace and node names was added with the fix for FIN APAR
  IC90010 that was put into the 7.1.0 server level.  The Tivoli
  Storage Manager documentation needs to be updated to reflect
  that fact that at 7.1 and above select from occupancy can return
  this "DELETED" value for filespace and nodename under the given
  circumstances.
  Tivoli Storage Manager Versions Affected: 7.1 all platforms
