Configuration prerequisites

In addition to the configuration prerequisites covered in the Dell NetVault Backup Plug-in for NDMP User’s Guide, verify that the following requirements are met:

•

Start the NDMP Service: On the Hitachi NAS Server, configure the NDMP services to start at boot time.

•

Create a user account for NDMP backups and restores: Create a user named “ndmp” on the filer using either the HNAS command line interface or web interface. Consult the relevant filer documentation for instructions on creating a user account. Log in with this user account when adding the NDMP Server or re-configuring the plug-in authentication details.

•

Configure NDMP options on the Hitachi NAS filer: Before adding the Hitachi NAS filer to the NetVault Backup Server, configure the following NDMP options on the filer.

•

Enable Reporting all Objects in the filesystem:

ndmp-option report_as_fs all

•

Set SCSI Reserve/Release to “None”:

ndmp-option reserve_devices none

•

Set Mover Window Adjust to “None”:

ndmp-optoin mover_window_adjust none

•

Assign aliases to devices: Before adding the Hitachi NAS filer to the NetVault Backup Server, assign aliases to devices.

To assign aliases to the devices

Log on to the filer.

For each device, assign an alias for NetVault Backup access. You can use the CLI command ndmp‑device-assigned-name-set to assign aliases. Use the device node name, such as mt_d0l1. Do not use the subsystem or absolute path, such as /dev/mt_d0l1.

Example:

ndmp-device-assigned-name-set -s 1387409413 --override mt_d0l2

ndmp-device-assigned-list

Output:

There are 6 names assigned to NDMP devices:

mc_d0l0 FC Node WWN (hexadecimal): 0x2000000d7709a3dc Logical Unit Number: 0

ndmp-device-assigned-name-list Serial number: test1:$

mt_d0l1 Serial number: 1387409412

mt_d0l2 Serial number: 1387409413

mt_d0l3 Serial number: 1387409414

mt_d0l4 Serial number: 1387409415

•

Configure the “NDMP Server Type” setting: This setting is only applicable to filers running BlueArc OS or HNAS firmware 8.x and later. It is configured while adding the NDMP Server to specify the backup mode for the filer. The plug-in client offers the following selections in the NDMP Server Type list:

•

BlueArc BOS 8.x NDMP Server using dump

•

BlueArc BOS 8.x NDMP Server using image

•

Hitachi HNAS 10.x NDMP Server using dump

•

Hitachi HNAS 10.x NDMP Server using image

•

Hitachi HNAS 11.x NDMP Server using dump

•

Hitachi HNAS 11.x NDMP Server using image

•

Hitachi HNAS 12.x NDMP Server using dump

•

Hitachi HNAS 12.x NDMP Server using image

Verify that you select the correct backup mode for the filer. A server added in Dump Mode can only be selected for Dump Backups. Similarly, a server added in Image Mode can only be selected for Image Backups.


	NOTE: The Image Backups are also known as HNAS JetImage Backups.

•

Allocate the backup device to the Hitachi NAS Server: After adding a device to the NetVault Backup Server, allocate this device to the Hitachi NAS Server. Consult the relevant filer documentation to complete this step.
