Use the Create Logical Drive - Specify Logical Drive Parameters dialog to specify logical drive name, usage, desired capacity, controller ownership, and storage partition mapping preference.
Important: If you select a Free Capacity node when invoking the Create Logical Drive option and there are no valid logical drive candidates, an error message is displayed and you are returned to the Management Window.

How to Specify Logical Drive Parameters
1 |
Specify the capacity units and logical drive capacity. Use the spinner box to indicate capacity units (in MB or GB) and list box to indicate the specific numeric capacity. The maximum value, shown by default, is the Maximum capacity shown in the Summary Area. Important:
|
||||||
2 |
Specify the logical drive name. Choose a unique, meaningful name that helps you identify the logical drive. Generally, a meaningful name describes the data that will be stored on the logical drive.
|
||||||
3 | Specify the expected usage of the logical drive based on your application needs. The expected logical drive usage that you specify is used by the controller firmware to indicate an appropriate default logical drive segment size and cache read-ahead multiplier. The choices available for expected logical drive usage include file system (the default), database, and multimedia. |
||||||
4 | Select an appropriate segment size for your application. You can choose
the default (based on expected usage), 8, 16, 32, 64, 128, or 256 K. Note: You can change the logical drive segment size later using the Change Segment Size option. See Changing Segment Size. |
||||||
5 | Specify controller ownership (a preferred controller). Note: This option is only available if you are using dual active controllers. Choices include either the controller in slot A or the controller in slot B.
|
||||||
6 | Specify whether the logical drive should have a default mapping or be left unmapped. For more information, see Introducing
Storage Partitions.
|
||||||
7 | Select Finish. Result: If the logical drive is successfully created, the Logical Drive Successful dialog is displayed. If there are any errors, an error message is displayed. |
||||||
8 | Select OK. Result: A logical drive (or array/logical drive) is created with the specified RAID level and parameters. You are returned to the Subsystem Management Window. The Logical View is updated to reflect the addition of the new array and/or logical drive and the subtraction of capacity from either the Free Capacity or the Unconfigured Capacity node. Note: To change other logical drive parameters, see Specifying Logical Drive Properties. |
||||||
9 | Perform any operating system modifications necessary on the application host so that the applications can use the logical drive. See the Installation and Support Guide specific to your operating system. |
