  • FAS8300
  • AFF-C60
  • ONTAP 9
  • SnapMirror
  • XDP
  • Storage Efficiency

Issue

  • An issue occurred where storage efficiency was not applied after transferring data from a FAS8300 system—where deduplication had been disabled—to an AFF C60 system using SnapMirror
  • The main concern was that, after SnapMirror initialization, the destination volume on the AFF C60 did not have deduplication enabled and therefore were not reclaiming storage space as expected
