Error description

• If the TSM B/A client performs simultaneously a snapdiff backup
  on 2 or more separate NetApp filers as part of the same backup
  operation, in some cases the snapshots created on the filer may
  fail to be deleted upon successful completion.  This does not
  apply to multiple domain on a filer for example:
  domain \\filer1\domain1 \\filer1\domain2 \\filer1\domain3
  It will affect multiple filers and domains:
  domain \\filer1\domain1 \\filer1\domain2 \\filer2\domain1
  \\filer2\domain2
  The problem may not always occur on all domains or filers.
  Tivoli Storage Manager Versions Affected: 6.2
  Initial Impact: Low
  Additional Keywords:
  NAS snap snapshot differential removed erased
  

Local fix

• Perform a separate backup for each individual NetApp filer.
