Applies to

  • Unified Manager 9.x (UM 9.x)
  • ONTAP 9

Issue

  • when restoring a file from a remote backup volume snapshot or generally a file from shapshot to a different cluster it fails
  • mostly there is an error after 5 minutes which is the UM ndmp timeout
  • restoring a file from local snapshot to same or different location on the same cluster does work
  • ndmp restore (which UM utilizes) does work on cli using ndmpcopy command
