Modifying a Subclient of Lustre

You can modify an existing Lustre subclient based on your requirements.

Procedure

1. From the CommCell Browser, expand Client Computers > pseudo-client > Big Data Apps > instance.

2. Right-click the subclient for which you want to modify options, and then click Properties.

   The Subclient Properties dialog box appears.

3. Modify the basic settings for the subclient:

   1. In the Subclient Name box, type a name.

   2. On the Data Access Nodes tab, select the data access nodes that you want to add to the subclient, and then click Add.

   3. On the Content tab, click Browse to select the directory or file that you want to back up, and then click Add.

      Note

      • The default subclient does not back up the content that you specify in user-defined subclients which are within the same instance.

      • Subclient content paths can only be Lustre mount points. You can configure only one Lustre mount point for a subclient.

      • Nested Lustre volumes are not allowed.

   4. Click Advanced.

      The Advanced Subclient Properties dialog box appears.

4. On the Performance tab, specify the number of data streams:

   1. In the Number of Data Readers box, enter the number of data streams.

      Tip: For optimal sharing of the backup load, the number of data readers must be equal or greater than the number of data access nodes.

   2. Select the Allow multiple data readers within a drive or mount point check box

   3. Click OK.

5. On the Storage Device tab, select a storage policy from the Storage Policy list.

6. To create a new storage policy, click Create Storage Policy and follow the instructions in the storage policy creation wizard.

7. To perform LAN-free backup and restores, select a grid storage policy.

   For more information, see GridStor^® (Alternate Data Paths) - Overview.

   By configuring keyless SSH between the MDT server and the data access nodes, you can also use the MediaAgent as a data access node.

8. Click OK.
