See Creating Arrays and Logical Drives in this section for more information.
3. Create arrays using the available physical drives.
4. Define logical drives using the arrays.
5. Save the configuration information.
6. Initialize the logical drives.
See Initializing Logical Drives in this section for more information.
Designating Drives as Hot Spares
Hot spares are physical drives that are powered up along with the RAID drives and usually stay in a standby state. If a hard drive used in a RAID logical drive
fails, a hot spare will automatically take its place and the data on the failed drive is reconstructed on the hot spare. Hot spares can be used for RAID levels 1,
5, 10, and 50. Each controller supports up to eight hot spares.
The methods for designating physical drives as hot spares are:
l Pressing while creating arrays in Easy, New or View/Add Configuration mode.
l Using the Objects—> Physical Drive menu.
Key
When you select any configuration option, a list of all physical devices connected to the current controller appears. Perform the following steps to designate a
drive as a hot spare:
1. On the Management Menu select Configure, then a configuration option.
2. Press the arrow keys to highlight a hard drive that displays as READY.
3. Press to designate the drive as a hot spare.
4. Click YES to make the hot spare.
NOTE: In the BIOS Configuration Utility and Dell Manager, only global hot spares can be assigned. Dedicated hot spares cannot be assigned.
