Configuring full cluster backups to directly attached tape devices

You can configure Tivoli® Storage Manager to back up all volumes in a NetApp cluster to a directly attached tape device.

Before you begin

For an overview of NDMP functionality in Tivoli Storage Manager and NetApp file servers, see technote 7046965. This technote also lists system requirements.

If the NetApp Clustered Data ONTAP 8.2 or later operating system is installed on your NetApp file server, use the following procedure. After you configure your NetApp file server to work with Tivoli Storage Manager, you can use the NetApp Cluster Aware Backup (CAB) extension to back up all volumes.

If the NetApp Clustered Data ONTAP 8.2 or later operating system is not installed on your NetApp file server, back up data by following the instructions in Configuring Tivoli Storage Manager for NDMP operations in a nonclustered environment.

About this task

The preferred method is to back up the full cluster by using a node and data mover that are associated with the clusterwide network. In this way, you ensure that the backup data is owned by a single Tivoli Storage Manager node. Even if you move volumes within the cluster, backup operations continue and no reconfiguration is required.

Procedure

To configure full cluster backup operations to a directly attached tape device, complete the following steps:

Verify that Tivoli Storage Manager Extended Edition is installed, and that the license is registered. If the license is not registered, issue the following Tivoli Storage Manager command:
```
register license file=tsmee.lic
```
Obtain cluster administrator privileges for the NetApp file server. This step is required to access the cluster console.
On the NetApp file server, enable the use of NDMP by following the instructions in the Clustered Data ONTAP® Data Protection Tape Backup and Recovery Guide. Complete the following steps:
1. Enable SVM-scoped NDMP backup operations at the cluster level. In this way, you disable node-scoped NDMP backup operations on the NAS file server. Ensure that the node-scoped-ndmp option on the NAS file server is set to OFF.
2. Create a backup user ID for NDMP operations.
3. Configure a network interface for NDMP control connections at the cluster level.
Register the Tivoli Storage Manager node that will own all backup data for the cluster. On the Tivoli Storage Manager server, issue the REGISTER NODE command:
```
register node node_name password domain=nas_domain type=nas
```
where node_name specifies the node name, password specifies the node password, and nas_domain specifies the domain of the node. Assign the node to a domain that has a policy to back up data to an appropriate storage pool.
Determine the IP address of the NetApp intercluster interface on the NAS file server. The interface must provide access to the entire cluster. On the NAS file server, issue the following Data ONTAP operating system command:
```
network interface show -role intercluster
```
This value is required when you specify the HLADDRESS parameter in step 6.
Define a data mover for the Tivoli Storage Manager node that will own the backup data. On the Tivoli Storage Manager server, issue the DEFINE DATAMOVER command on one line:
```
define datamover data_mover_name type=nascluster
hladdress=intercluster_interface lladdress=port 
USER=user_name password=password dataformat=netappdump
```
where intercluster_interface is the value that you obtained in step 5 and data_mover_name is the node name that you registered in step 4. For information about specifying the other parameters, see DEFINE DATAMOVER (Define a data mover).
Tip: After you define the data mover, additional data movers are defined automatically for each node in the cluster. The name of each data mover matches the name of the physical node in the cluster. You will use these data movers when you define paths to tape drives in step 3 of Configuring tape devices for full cluster backups.

What to do next

To configure the tape device for the full cluster backup, follow the instructions in Configuring tape devices for full cluster backups.
