ONTAP 9.13.1 commands

vserver services ndmp log start

Start logging for the specified NDMP session

Availability: This command is available to cluster and Vserver administrators at the advanced privilege level.

Description

This command is used to start logging on an active NDMP session on a vserver.

Parameters

-vserver <vserver name> - Vserver

This parameter specifies the name of the Vserver.

-session-id <text> - Session Identifier

This parameter specifies the NDMP session-id on which logging needs to be started.

-filter <text> - Level Filter

Use this parameter to specify the filter for a particular session ID. This parameter controls the NDMP modules for which logging is to be enabled. This parameter can take five values. They are as follow : all , none , normal , backend or "filter-expression" . The default value for this is none .

  • all turns on logging for all modules.

  • none disables logging for all modules.

  • normal is a short cut parameter that enables logging for all modules except verbose and io_loop . The equivalent filter string is all-verbose-io_loop

  • backend is a short cut parameter that enables logging for all modules except verbose , io_loop , ndmps and ndmpd . The equivalent filter string is all-verbose-io_loop-ndmps-ndmpp

  • (filter-expression) is a combination of one or more modules for which logs needs to be enabled. Multiple module names can be combined using following operators :

  • - to remove the given module from the list of specified modules in the filter string. For example the filter all-ndmpp will enable logging for all modules but not ndmpp .

  • ^ to add the given module or modules to the list of modules specified in the filter string. For example the filter ndmppmoverdata will enable logging for ndmpp , mover and data .

The possible module names and a brief description is given below:

Examples

The following example shows how to start logging on a specific NDMP session 1000:35512, running on vserver cluster1-01 with filter all.

cluster1::*> vserver services ndmp log start -vserver cluster1-01 -session-id 1000:35512 -filter all
