Designating Drives as Hot Spares
Hot spares are physical drives that are powered up along with the RAID drives and stay in a standby
state. If a disk drive used in a RAID logical drive fails, a hot spare will automatically take its place.
The data on the failed drive is reconstructed on the hot spare. Hot spares can be used for RAID
levels 1, 3 and 5. Each adapter supports up to eight hot spares.
Use one of the two methods described below to designate physical drives as hot spares.
