适用场景

  • 集群模式 Data ONTAP 8.1
  • Data ONTAP 8.1 7-模式

问题解答

在Data ONTAP 8.1 (及更高版本) ndmpd start/stop/terminate 中、引入了一个新的"高级"命令集、可用于停止和重新启动NDMPD服务本身。在7-模式和集群模式版本的Data ONTAP 中都可以使用相同的命令。

注意:7-Modeclustered DOT命令集都是"高级"级别的命令

7-模式

ndmpd start/stop 命令用于控制节点的NDMP服务守护进程。这与 ndmpd on/off 命令不同、该命令可通过守护进程启用或禁用NDMP请求处理、但不控制/修改守护进程本身。ndmpd start/stop 此命令还将在节点上托管的所有vFiler单元上禁用NDMP服务。

ndmpd stop 此命令会造成系统中断、在正常情况下不应使用。活动会话将继续处理、但无法查看或使会话过期。

ndmpd terminate 此命令将终止节点上所有活动的NDMP会话、同时使NDMPD守护进程过期。

警告:此命令会强制终止所有NDMP会话、而不会有关闭的机会。

ndmpd terminate 运行命令后、NDMPD守护进程将自动重新启动。与 stop 命令一样、 terminate 也是一个中断命令、不应在正常情况下使用。

语法示例

filer-rtp> priv set advanced

filer-rtp*> ndmpd stop

filer-rtp*> ndmpd start

filer-rtp*> ndmpd terminate

集群模式

system services ndmp start/stop 命令用于启动或停止特定节点的NDMP服务守护进程。这与 system services ndmp on/off 启用或禁用守护进程以接受NDMP请求的命令不同。

system services ndmp stop 此命令会造成系统中断、在正常情况下不应使用。活动会话将继续处理、但无法查看或使会话过期。

system services ndmp terminate 命令将终止节点上的所有活动会话、同时使NDMPD守护进程过期。

警告:此命令会强制终止所有NDMP会话、而不会有关闭的机会。

system services ndmp terminate 运行命令后、NDMPD守护进程将自动重新启动。与 stop 命令一样、 terminate 也是一个中断命令、不应在正常情况下使用。

语法示例:

cluster-rtp::> set -privilege advanced

cluster-rtp::*> system services ndmp stop -node [node_name]

cluster-rtp::*> system services ndmp start -node [node_name]

cluster-rtp::*> system services ndmp terminate -node [node_name]
