NDMP process management
Normally all NDMP actions are controlled from the DMA. However, if the DMA cannot resolve a
problem or you suspect that the DMA may have incorrect information about the NDMP environment,
take the following actions from the X9000 Software management console GUI or CLI:
• Cancel one or more NDMP sessions on a file serving node. Canceling a session kills all spawned
sessions processes and frees their resources if necessary.
• Reset the NDMP server on one or more file serving nodes. This step kills all spawned session
processes, stops the ndmpd and session monitor daemons, frees all resources held by NDMP, and
restarts the daemons.
Viewing or canceling NDMP sessions
To view information about active NDMP sessions, select Cluster Configuration from the Navigator,
and then select NDMP Backup > Active Sessions. For each session, the Active NDMP Sessions panel
lists the host used for the session, the identifier generated by the backup application, the status of the
session (backing up data, restoring data, or idle), the start time, and the IP address used by the DMA.
To cancel a session, select that session and click Cancel Session. Canceling a session kills all spawned
sessions processes and frees their resources if necessary.
To see similar information for completed sessions, select NDMP Backup > Session History.
To view active sessions from the CLI, use the following command:
ibrix_ndmpsession –l
To view completed sessions, use the following command. The -t option restricts the history to sessions
occurring on or before the specified date.
ibrix_ndmpsession –l -s [-t YYYY-MM-DD]
To cancel sessions on a specific file serving node, use the following command:
ibrix_ndmpsession –c SESSION1,SESSION2,SESSION3,... –h HOST
Starting, stopping, or restarting an NDMP Server
When a file serving node is booted, the NDMP Server is started automatically. If necessary, you can
use the following command to start, stop, or restart the NDMP Server on one or more file serving
nodes:
ibrix_server –s –t ndmp –c { start | stop | restart} [-h SERVERNAMES]
