• Closed as program error.

Error description

• If a disk storage pool has "Cache migrated files" set to yes,
  backups can fail if the cached files reach 100% of the pool
  occupation.
  
  The storage pool information will show:
  Pct Util: 100.0
  Pct Migr: 0.0
  Pct Logical: 100.0
  .
  Cache Migrated Files?: Yes
  
  This means that the pool is full with cached files, that should
  be automatically deleted when space is needed during backups.
  What can happen instead is that the cached data deletion fails
  and as consequence backups directed to this storage pool will
  fail as well.
  
  Customer/L2 diagnostic:
  Client will log messages like:
  Incremental backup of volume '/boot'
  Normal File-->         1,402,666

  Server log will not show any error, but a SESSION trace will
  contain:

  when termReason is (0)
  
  This problem can also occur during any attempt to store data to
  a pool disk storage pool has "Cache migrated files" set to yes
  and the cached files reach 100% of the pool occupation.  Here is
  an example of errors during import processing:
  
  ANR9999D_2458713350 XiImportObject(xibf.c:1335)
  Thread<##>: Unknown result code (79) from bfCreate.
  
  
  TSM Versions Affected:
  6.1 on any platform
  
  Initial Impact:
  Medium
  

Local fix

• Empty the affected storage pool manually using the following
  command against all volumes in the pool:
  MOVE DATA <volume_name>
  and set "Cache migrated data" to NO to avoid the storage pool
  fill up and backups fail again.
