NDMP备份已中止"连接已关闭/已中止、但未关闭命令"

• ONTAP 9
• NDMP

• DMA上的备份作业似乎挂起和/或DMA暂停备份。
• 启用NDMP调试日志记录(SVM范围的NDMP / 节点范围的NDMP)并 检查日志后，会出现以下错误：
• backup.log

"Error (Message from Write Dirnet: Interrupted system call)"
"Error (DUMP IS ABORTED)"

• ndmpd.log

"DEBUG: BUF_Stream::input: fd=13 read -1 [EOF or error]: Connection reset by peer (ndmp_io_process)"
"DEBUG: connection closed/aborted without CLOSE command from [DMA_IP_address].port"
这表示DMA (备份应用程序)未发送NDMP4_data_ABORT NDMP消息以中止备份。
