  • Closed as program error.

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.
