Introduction

In this video, youll learn how to configure an EMC

Celerra

system for NetworkData Management Protocol (NDMP) backups over Fibre Channel.

NDMP is an open standard network protocol designed for enterprise-wide

backup and recovery of heterogeneous network-attached storage. PerformingNDMP backup jobs over Fibre Channel is the most efficient method for backingup large amounts of data.

The NDMP client is responsible for sending the backup softwares control data,such as scheduling, cataloging, and TLU commands, across the network to theNDMP server, which is the Celerra Data Mover.

The Data Mover executes and maintains the backup and restore processes. Amaximum of four simultaneous backups are supported on each NDMP-host DataMover.

Backup data flows from the storage system to the Data Mover to an attached

tape library unit (TLU) without traversing the network.

Environment

Before we get started, we will have to have a Celerra Network Server with anNDMP server accessible by using Fibre Channel.

So lets get started.

Connect the NDMP Server to the Celerra

The first step is to physically connect the NDMP server to the AUX ports on theData Mover of the Celerra.

The Celerra has two specialized Fibre Channel (FC) ports on each Data Mover

that are reserved for NDMP functionality. These ports are clearly labeled on theback of the Data Mover as AUX0 and AUX1.

Note that the ports are not labeled on the NS-960 and NS-G8.

The ports were built into the Celerra design to avoid Fibre Channel Port (FCP)congestion. This allows data to be backed up to be received over the primary FCchannels from the storage array, and then redirected over the AUX connectionsdirectly to the NDMP library.

To connect the NDMP server:

1. Connect the Fibre Channel cables to the AUX ports on the Data Movers.

Its important to note that you may need a media interface adapter toconvert the copper connector to the fiber optic.

If the Fibre Channel cable is going to be plugged into a SAN switch, youneed to perform zoning between the HBA on the Data Mover and thetape drive or tape library.

2. First you need to know the worldwide name (WWN) of the Data Mover.To obtain the WWN of the Data Mover, run the server_sysconfigcommand from the Celerra command line interface.

The WWN of the AUX0 port will be listed as fcp-2, and the WWN ofAUX1 will be listed as fcp-3.

3. Now our SAN Administrator can perform the zoning.

4. After the zoning is completed, we can confirm that the newly presentedtape drives are accessible from the Data Mover over the Fibre Channelconnection by using the server_devconfigcommand.

The tape drives appear on the chains with an id of 32 or higher. This confirmsthat the Fibre Channel cabling, zoning, and tape library configurations areconfigured correctly and are accessible.

Next, well update the Celerra database with the newly configured NDMP tapedrives.

Update the Celerra database with the NDMP tape drives

1. Well use the server_devconfigcommand with the create, scsi, and alloptions to rescan the tape drives to discover them and add them to thedatabase.

2. Now, well make sure that the tape drives or robot are created on theData Mover by using the server_devconfigagain with the list, scsi, andnondisk options.

Create an NDMP user account on the Data MoverFinally, we are ready to create an NDMP user account on the Data Mover byusing the MD5 password encryption method. The backup client uses thesecredentials to access and initiate backup jobs on the Data Mover.

Note: For security reasons, EMC recommends that you use the MD5 passwordencryption method. Use this password method only to create an NDMP accountin the NIS environment. Also, ensure that the NDMP.md5 parameter is set to 0(zero) on all the Data Movers in this environment.

Lastly, its important that we do not use Control-C in response to the commandprompts because it will cause the command to hang.

1. To create the account, well use the server_usercommand with the add,MD5, and password options.

The Celerra Network Server uses User IDs (UIDs) and Group IDs (GIDs)to record the ownership of files and directories.

2. The home directory is not used here, so well leave the setting blank.

3. Next, well assign a password between 6 and 8 characters long, and wellavoid using special characters because they can cause authenticationproblems.

Weve completed all of the steps for setting up a basic NDMP configuration withthe Celerra Network Server.

Youll want to refer to your backup vendor software documentation to completethe required configuration on the backup software.
