适用场景

  • ONTAP 9.10.1及更高版本
  • LIF服务策略

问题描述

注意: NDMP协议将备份应用程序称为数据管理应用程序(DMA)。 

  • 升级 到ONTAP 9.10.1及更高版本后、先前工作的NDMP备份将失败。
  • 升级到ONTAP 9.10.1及更高版本后、尝试配置新的NDMP备份也会失败。
  • 如果为运行ONTAP 9.10.1及更高版本的集群配置新的NDMP备份、也可能发生相同类型的故障。
  • 失败的备份或配置尝试与DMA和NDMP服务器之间的连接错误相关
    • 在DMA端、可能会出现如下错误:

NDMP connection to  host [NetApp hostname] failed.

  • 这些连接错误可能与NDMP 控制连接的连接 文件和NDMP 数据连接的文件有关
    • 控制连接 是从DMA到NDMP服务器的初始连接。  
    • 数据连接 是指从NDMP服务器到DMA的连接、用于通过网络发送NDMP数据流。
  • NDMP配置(包括身份验证)已配置且显示正确
  • DMA配置中的NDMP主机名或IP地址对应于 数据LIF或使用自定义服务策略的LIF
  • 对于数据Rifs、来自DMA的失败连接不会记录到ndmpd日志中
  • 对于使用自定义服务策略的非管理生命周期、NDMP调试日志可能包含与失败的DMA连接尝试对应的单个错误:
ERROR: LIF Role [0] detected is invalid
