These steps are required only if the storage server has tape drives attached to it. Backups can be written to libraries on the MediaAgent or to libraries on other storage servers.
The settings of the storage server determine how the storage server connects to the MediaAgent. If you want to define the interface used to connect the MediaAgent to the storage server, you can use the Data-Interface-Pairs (DIP) feature from the CommCell Console. See Data-Interface-Pairs.
Before You Begin
For NetApp Cluster-Mode storage servers, consider the following:
-
Tape drives can be detected and configured on the physical nodes on the cluster or on the cluster interface as follows:
-
Detecting and configuring tape drives using the cluster interface will create a cluster drive pool that is independent of any physical node and will contain all the tape drives seen on all nodes of the cluster.
-
Detecting and configuring tape drives on a physical node will create a drive pool for that physical node.
-
-
Using a storage policy whose primary copy contains a cluster drive pool:
-
Vserver client backups and cluster client backups will attempt to match the node of the backup path with the node of the tape drive. If a match is found, the data will be backed up with a local two-way backup using the cluster interface and data will not be passed between nodes in the cluster.
-
Vserver client backups when no match is found will choose a node that can see the tape drive and run a backup using the vserver interface. The backup data will be passed between nodes in the cluster.
-
Cluster client backups when no match is found will choose a node that can see the tape drive and run a backup using the cluster interface. The backup data will be passed between nodes in the cluster.
-
-
Using a storage policy whose primary copy contains a physical node drive pool:
-
Vserver client backups will be local two-way within the cluster when backing up volumes that reside on the same physical node as the tape drive. This local two-way backup will use the physical node interface. Data will not be passed between nodes in the cluster.
-
Cluster client backups will be local two-way within the cluster when backing up volumes that reside on any physical node that can access the tape drive. Even if the drive pools on a physical node are configured using the Expert Storage Configuration Tool, a cluster client will still access the tape drive through the physical node that contains the backup data.

For Dell EMC Isilon/PowerScale, consider the following:
-
Configure tape drives on a SmartConnect DNS Zone:
The Dell EMC Isilon/PowerScale file server can be configured with a DNS name representing one or more nodes in the cluster (also known as the SmartConnect DNS Zone). To optimize backup performance, configure the SmartConnect zones to contain Backup Accelerator nodes that have more memory as well as the capability to connect tape drives. As the Backup Accelerator nodes are added to the cluster, they can be added to the SmartConnect zone without the need to change Commvault library and drive configuration. Each node in the SmartConnect zone must have access to all the tape drives. If the nodes do not see all the tape drives, then configure only the tape drives seen by all nodes. For more information about considerations for Dell EMC Isilon/PowerScale file servers, see Considerations for Dell EMC Isilon/PowerScale File Servers.
Procedure
-
From the CommCell Console ribbon, on the Storage tab, click Expert Storage Configuration.
The Select MediaAgent dialog box appears.
-
Under Available MediaAgents, select the MediaAgent, and then click Add.
-
Click OK.
-
In the Expert Storage Configuration dialog box, click Start.
-
Select Detect/Configure Devices.
-
Click NDMP Devices.
The MediaAgent that controls the library is displayed.
-
Click OK.
-
Under Available NDMP Servers, select the name of the file server, and then click Add.
-
Click OK.
-
Click Yes.
-
Click Close.
-
Click OK.
-
Right-click the library, and then select Configure.
-
To configure all the drives within the library, click Library and all drives.
-
Click OK.
-
Click Yes.
-
From the list, select Default Media Type, and then click Yes.
Result
The status of the library changes to Configured. If you chose to configure all associated drives, the status of the drives also changes to Configured.
The Libraries tab provides the physical view of the devices (library and drives).
The Data Paths tab provides a logical view of the data path used to access the devices - library, master drive pool, drive pool, drive.
