# Increasing logical drive size

Use this action to add space to an existing logical drive so you can increase its size.

When you create a logical drive, it is striped across all of the physical drives used by the logical drive. To increase the size of an existing logical drive, you add segments to the logical drive, which can be on the same or different disks. Then, the ServeRAID Manager migrates the logical drive such that the data is spread across the existing and new physical drives.

Notes:
  1. The capacity of the modified logical drive must match or exceed its current capacity.
  2. The maximum size of a logical drive is 2 terabytes (TB).

1. In the Logical devices view, click (logical drive).
2. Right-click Expand or change logical drive. The Configuration wizard opens with the "Choose RAID level" window. Click Next. The "Create logical drives" window opens.
3. Add segments to the logical drive. Optionally, click Advanced to select a new stripe-unit size for the logical drive.

   Note: To remove or replace a physical drive, click the drive you want to remove (indicated by ); then, click the drive you want to replace it with. To cancel your changes and start over, click .

   When you are ready to continue, click Next. The "Configuration summary" window opens.

4. Review and apply your new configuration or schedule the migration for another time.
5. After the logical-drive migration is complete, create additional partitions to use the expanded logical-drive space. If the server is a Microsoft Windows system, you can extend the size of a pre-existing partition with the newly acquired logical-drive space.
