Reserved Disk Space during Configuration
Up to 20.6 MB of disk space is reserved when a hard drive is being
configured.
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. The hot spare drive should be
larger than or equal to the smallest logical drive. 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 and 5. Each PERC 3 controller supports up to eight
hot spares.
The methods for designating physical drives as hot spares are:
•
Pressing <F4> while creating arrays in Easy, New or View/Add
Configuration mode, or
•
Using the Objects—> Physical Drive menu.
Press <F4>

connected to the current controller appears. Perform the following steps to
