Modifying logical drives on ServeRAID SAS and SATA controllers
(ServeRAID-7t, ServeRAID-8i)
Changing the RAID level: You can change the RAID levels of currently
defined logical drives.
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.
3. Choose a new RAID level for the logical drive; then, click Next. The Create
Logical Drives window opens.
Note: Only valid RAID level migrations appear in the list. Migration
requirements for each RAID level are described here.
4. Add the physical drives needed to support the new RAID level (if any). Click
Advanced settings to set the logical drive size; optionally, select a new
stripe-unit size. Then, click Next. The Configuration Summary window opens.
Note: When you add drives, the migration wizard shows the current layout of
the data, including the current logical drive size. For most migrations,
you will need to increase the logical drive size setting; the default size is
not generally adequate once you add drives or segments.
5. Review and apply the new configuration.

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.
