5.5 HP StorageWorks X9300 Network Storage Gateway Administrator Guide (AW539-96007, March 2011)

• Three-way NDMP operations between two X9000 systems
Each file serving node functions as an NDMP Server and runs the NDMP Server daemon (ndmpd)
process. When you start a backup or restore operation on the DMA, you can specify the node and
tape device to be used for the operation.
Following are considerations for configuring and using the NDMP feature:
• When configuring your system for NDMP operations, attach your tape devices to a SAN and then
verify that the file serving nodes to be used for backup/restore operations can see the appropriate
devices.
• When performing backup operations, take hardware snapshots of your file systems and then back
up the snapshots.
Configuring NDMP parameters on the cluster
Certain NDMP parameters must be configured to enable communications between the DMA and the
NDMP Servers in the cluster. To configure the parameters on the management console GUI, select
Cluster Configuration from the Navigator, and then select NDMP Backup. The NDMP Configuration
Summary shows the default values for the parameters. Click Modify to configure the parameters for
your cluster on the Configure NDMP dialog box. See the online help for a description of each field.
To configure NDMP parameters from the CLI, use the following command:
ibrix_ndmpconfig –c [-d IP1,IP2,IP3,...] [-m MINPORT] [-x MAXPORT] [-n LISTENPORT]
[-u USERNAME] [-p PASSWORD] [-e {0=disable,1=enable}] –v {0=10}] [-w BYTES]
[-z NUMSESSIONS]
