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 physical drive used in a RAID

for RAID levels 1 and 5. Each PERC 3 controller supports up to eight hot
spares. See Chapter 2 "Introduction to RAID" for an explanation of hot
spares.
Perform the following steps to designate physical drives as hot spares:
