# Creating a hot-spare drive

Use this action to create a global hot-spare drive.

For all controllers except the ServeRAID-8i, a global hot spare can be used to rebuild only one logical drive at a time: the first drive that needs it after a physical drive in an array fails. (Use copy back to restore the hot spare and logical drive to their original configuration.) For the ServeRAID-8i (only), a global hot spare can be used to rebuild one or more logical drives if sufficient space remains after a rebuild is complete.

Notes:

- A hot-spare drive with a blue plus sign next to it indicates that the logical devices are protected by the hot spare. A hot-spare drive with a yellow plus sign next to it indicates that:
  - The drive is too small to protect any drives in the logical devices
  - None of the logical devices support hot spares (for example, a RAID Level-0 array)
  - No logical devices are defined
- This action is supported on the integrated RAID controller in bootable-CD mode only.

To create a hot-spare drive:

1. In the Physical devices view, click (ready physical drive) or (standby hot-spare drive).
2. Click in the Logical devices view. The ServeRAID Manager creates the hot-spare drive.
