You can add new logical devices to your storage space at any time, as long as adequate disk drive space is available. Adaptec Storage Manager offers two methods for creating logical devices—express configuration and custom configuration. This section describes how to use the express configuration method.
Note! For instructions on creating logical devices using custom configuration, click here.
When you use Express configuration, Adaptec Storage Manager automatically creates logical devices by grouping together same-sized physical disk drives, and assigns RAID levels based on the number of physical disk drives in a logical device:
A logical device with three or more physical disk drives is assigned RAID 5.
A logical device with two physical disk drives is assigned RAID 1.
A logical device with only a single physical disk drive becomes a simple volume, which does not offer redundancy.
Note! To create a logical device with any other RAID level, you must use the custom method. See How RAID Protects Your Data for more information about RAID levels.
SAS and SATA disk drives are grouped in separate logical devices.
Logical device size is set by Adaptec Storage Manager and automatically maximizes the capacity of the disk drives. Logical device size can not be adjusted during creation. To change the logical device size after a logical device has been created, see Adding Capacity to a Logical Device.
To Create Logical Devices with the Express Method:
In the Enterprise View, select a controller.
On the tool bar, click Create.
Alternately, click the Create Logical Device button in the Logical Devices View.
The wizard opens.
Select Express configuration..., then click Next.
Review the information in the configuration summary.
To exclude specific disk drives or to make other changes, click Modify logical devices; then, follow these instructions to finish creating your logical device(s).
Click Apply, then click Yes to confirm.
The logical device(s) are created.
Caution! Do not remove any drive included in the logical device while it is building.
