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 <F4> while creating arrays in Easy, New or View/Add Configuration mode.
l Using the Objects—> Physical Drive menu.

<F4> 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 <F4> to designate the drive as a hot spare.
4. Click YES to make the hot spare.

The drive displays as HOTSP.
5. Save the configuration.
