  • ONTAP 9
  • NDMPCopy
  • FSx

Issue

  • The dump side(source) of the NDMPCopy failed with “Write to socket failed.”
  • The restore portion(destination) of NDMPCopy failed with "received CLOSE command from [10.36.42.229].x" 
  • In NDMPCopy the DMA is the node-mgmt LIF of the node on which the command is executed – in this case, 10.36.42.229.
  • Simultaneous packet traces was collected on both systems on the interfaces hosting IPs used by NDMPCopy
  • It indicated that a device in the network is blocking the restore after it has started - multiple restransmissions by the source of the copy
  • The abort from the DMA(10.36.42.229) is in response to the source of the copy resetting the connection after multiple retransmissions
