Increasing free space

Note: This action is not supported on the integrated RAID controller.

Using this action you can add one, two, or three physical drives to an existing array so that you can create another logical drive in the array.

When you create an array, logical drives are striped across all physical drives in that array. To create more free space in an existing array, define additional physical drives to add to the array. Then, the ServeRAID Manager migrates the logical drives such that the data is spread across the existing and new physical drives.


    1. To increase free space in an array, you need at least one ready drive that is at least as big as the largest drive in the array.

    2. You can schedule the logical-drive migration for a later date and time when you review the configuration changes.

    3. (Cluster and failover configurations only) A logical drive will not failover while undergoing logical-drive migration.

  1. In the Logical devices view, click(array).

  2. Right-click Logical-drive migration Increase free space. The Configuration wizard opens with the "Create arrays" window.

  3. Add the physical drives to the array. When complete, click Next. The "Configuration summary" window opens.

  4. Review and apply your new configuration.

  5. After the logical-drive migration is complete, create a new logical drive in the new free space.
