This node-scoped NDMP command is deprecated. Node-scoped NDMP functionality may be removed in a future release of Data ONTAP. Use the Vserver-aware "vserver services ndmp log start" command.

This command is used to start logging on an active NDMP session on a node. You can start logging two different kinds of sessions. The NDMP server session manages all NDMP tasks on the node. If you want to log information regarding the NDMP server, use server with the -session-id parameter to enable logging. If you want to log information about a particular NDMP session, for example a restore operation, then determine the session ID for the session using the "system services ndmp status" command and use that ID with the -session-id parameter to enable logging.

Parameters

-node {<nodename>|local} - Node

This parameter specifies the node.

-session-id {<integer>|server} - Session Identifier

This parameter specifies the NDMP session-id on which logging needs to be started. The session-id is associated with a unique NDMP session. Specify server to start logging on the NDMP server session.

-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 ndmpp^moverdata 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 33522, running on the node cluster1-01 with filter normal.

cluster1::*> system services ndmp log start -node cluster1-01 -session-id 33522 -filter normal

The following example shows how to start logging on the NDMP server session, on the node cluster1-01 with filter all.

cluster1::*> system services ndmp log start -session-id server -filter all -node cluster1-01
