logical drive space, the ServeRAID Manager migrates the logical drives such that
the logical drives gain additional space, much like adding paper to a notebook.
When you create an array, logical drives are striped across all of the physical
drives in that array. To increase the size of the logical drives 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.
Note:
1. To increase the logical drive size, 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 logical-drive size. The
Configuration wizard opens with the Create Arrays window.
Note: This option is not available if the logical drive exceeds 2 terabytes using
any available physical drive.
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 additional partitions to use
the newly added 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.

Adding physical drives in an existing configuration: You can add physical
drives (also called logical-drive migration or LDM) to dynamically modify an
existing array and its logical drives.
Note: You cannot add more than three physical drives. The maximum number of
physical drives you can have in an array is still limited by the controller
stripe-unit size.
1. Click the appropriate Array tab in the right pane:
Then, from the list of ready drives, select the
drives you want to move to the array:
