NDMP

EMC VNX requirement

1. EMC supports NDMP drive sharing only through a storage area network (SAN).
2. VNX uses port 10000 for NDMP operations. NDMP three-way backups and restores

use dynamic port allocation from the Data Mover.

1. 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.
2. The Data Mover must have a minimum of 8 GB memory to run greater than four and up to eight NDMP sessions.
3. Auto extend should be set to “No"
4. Auto extend should be set to “No"
5. 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.

SSH login with EMC as nasadmin/nasadmin

• 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

To restart server_2

• type

$ server_cpu server_2 -reboot -monitor now

NDMP restrictions

1. NDMP backups and restores of iSCSI LUNs are not supported.
2. 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>
