NDMP
EMC VNX requirement
- EMC supports NDMP drive sharing only through a storage area network (SAN).
- VNX uses port 10000 for NDMP operations. NDMP three-way backups and restores
use dynamic port allocation from the Data Mover.
- VNX supports a maximum of eight concurrent NDMP sessions per NDMP-Host Data Mover. The backup client (DMA) should be compatible and configured to support up to eight concurrent NDMP sessions.
- The Data Mover must have a minimum of 8 GB memory to run greater than four and up to eight NDMP sessions.
- Auto extend should be set to “No"
- Auto extend should be set to “No"
- Tape cloning is supported; use your backup software to clone a tape, which moves it from disk to tape.
EMC VNX5300 NDMP setting
Note: NS series require an MIA for device connection to the AUX-0 port.
two SCSI connections connect the NDMP-Host Data Movers to the TLU. One SCSI connection is daisy chained to two tape drives, and the other is daisy chained to two tape drives and a robot. All Data Movers in Figure 7 on page 35 have two direct SCSI connections to VNX.
- In VNX for block environment, before you run the server_devconfig -create command,
verify that all paths to the Data Mover are active and no LUNs are trespassed.

查看和修改並發的NDMP會話(Options)
Click "Settings"->"Data Mover Parameters"->"NDMP"
NOTE: this action will need reboot Data Mover!
- Checking "concurrentDataStreams", consider change default value from 4 to 8.
* server_param server_2 –facility NDMP –info concurrentDataStreams
- server_param server_2 –facility NDMP –modify concurrentDataStreams –value 8
注意: 如果数据移动器的内存小于 8 GB,则无法将 concurrentDataStreams 参数设置为大于4。
查看和修改NDMP端口范围的值(Options)
server_param server_2 –facility NDMP –info portRange server_param server_2 –facility NDMP –modify portRange –value 50000-50100
To add an NDMP storage device IN BackupExec
- On the navigation bar, click Devices.
- In the task pane, under NDMP Tasks, click Add NDMP Server.
- In the Add NDMP Server dialog box, enter the following information:
NDMP Server: Enter the name of the NDMP Server.
Port: Enter the port to be used for communications between the Backup Exec Server and the NDMP Server.
Logon Account: Select the Logon Account for the NDMP server.
NDMP Server supports ICMP Ping Operations: Check NDMP Server supports ICMP Ping Operations to ensure that the Backup Exec can use ping to locate the NDMP Server.
4. Click OK to add the NDMP server.
5. After adding the NDMP server, restart Backup Exec services. The NDMP Server and the storage devices that are directly attached to it should appear in the Devices Tab in Backup Exec.
SHOW FCP
- server_config server_2 -v "fcp show"
To restart server_2
- type
$ server_cpu server_2 -reboot -monitor now
NDMP restrictions
- NDMP backups and restores of iSCSI LUNs are not supported.
- NDMP does not support the Archive Bit method; only the Date/Time stamp method is supported.
HowTo setup Celerra NDMP Backup using Symantec BackupExec

Just to be sure - the user name must be ndmp, not NDMP. Hopefully this is what you have done?
To add credentials from cmd on media server, you can use this command:
tpconfig -add -nh <celerra_host> -user_id ndmp -password <password>
To test/verify comms, use this command:
tpautoconf -verify <celerra_host>
