Creating a User-Defined Instance for IBM Spectrum Scale (GPFS)

While creating a new pseudo-client, you also create a user-defined instance.

You can create additional instances to manage different GPFS clusters.


  1. From the CommCell Browser, expand Client Computers > pseudo-client.
  2. Right-click Big Data Apps, point to All Tasks, and then click Create New Instance.

    The Create New GPFS Instance dialog box appears.

  3. In the Instance Name box, type the instance name.
  4. On the GPFS tab, specify the data access nodes to add to the instance.
    1. In the Master Node list, select one of the data access nodes as a master node for the instance.
    2. Under Data Access Nodes, select the data access nodes that you want to add to the instance, and then click Add.
    3. 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 greater than the number of data access nodes.

  5. On the Storage Device tab, select a storage policy from the Storage Policy list.
  6. Optional: To create a new storage policy, click Create Storage Policy, and then follow the instructions in the storage policy creation wizard.
  7. Optional: To perform LAN-free backup and restores, select a grid storage policy.

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

  8. Click OK.

A new instance is created with the name that you specify. A default subclient is created for the new instance.
