Designating Drives As Hot Spares - LSI SCSI 320-0 Configuration

Designating Drives as Hot Spares

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 disk 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, 3 5,
10, 30, and 50. Each MegaRAID controller supports up to eight hot spares.
The methods for designating physical drives as hot spares are:
•
press <F4> while creating arrays in Easy, New or View/Add Configuration
mode, or
•
From the Objects/Physical Drive menu, select a physical drive and press
<Enter>. Select Make HotSpare.

connected to the current controller appears, as shown below:

physical drive selection screen will appear. Select a disk drive and press <Enter>
to display the action menu for the drive.
Press the arrow keys to select Make HotSpare and press <Enter>. The indicator
