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 level 1, 3 and 5
RAID. Each MegaRAID controller supports up to eight hot spares. Refer to the
MegaRAID hardware guide for your board for an explanation of hot spares.
The two methods for designating physical drives as hot spares are:
•
press <F4> while creating arrays in Easy, New or View/Add Configuration
mode
•
highlight a drive using the space bar and press <Enter>. Select Make

drive selection screen will appear. Press the spacebar to 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
