APAR status

• Closed as program error.

Error description

• Client snapdiff backup can report errors for 'bind mount
  points'.
  A 'bind mount point' is an NFS subdirectories mounted via --bind
  mount option.
  
  ANS5250E An unexpected error was encountered.
     TSM function name : nsGetNasVolumeInfo():
     TSM function      : dmMapNfsVolume() failed to map remote
  volume for
     path: </mnt/tmpfs/mnt/log>.
     TSM return code   : 6213
     TSM file          : snapcommon.cpp (416)
  
  ANS1228E Sending of object  '/mnt/backup/location/*' failed.
  ANS4021E Error processing  '/mnt/backup/location/*': file system
  not ready
  ANS1802E Incremental backup of '/mnt/backup' finished with XX
  failure(s)
  
  Note that the ANS5250E is for a 'bind mount point', whereas the
  ANS1228E/ANS4021E message is for the desired filesystem.
  
  A bind mount point can be seen in the 'mount' command output:
  
  /mnt/data/log on /mnt/tmpfs/mnt/log type none (rw,bind)
  
  Tivoli Storage Manager client is incorrectly considering them as
  possible candidates for snapdiff processing.
  
  Tivoli Storage Manager Client Versions Affected:  6.3.x, 6.4.x
  and 7.1.x on Linux x86 platform
  
  
  
  Initial Impact: Medium
  
  Additional Keywords:  TSM snapdiff bind nfs mount
  

Local fix

• User could temporarily un-mount these bind mount points and run
  snapdiff backup to prevent the errors.
