Assign a Hot Spare
The HP NetStorage 6000 lets you assign physical drives to function as hot
spares. Hot spare drives are reserved drives that are used only when a
physical drive that is part of a logical drive fails. When this happens, the
system automatically selects the first available hot spare drive to take the
place of the failed drive. The logical drive is rebuilt using the hot spare, and
the hot spare drive becomes a member of the logical drive.
Once a hot spare is used to repair a logical drive, its assignment changes
from Hot Spare to Online. If you replace the failed drive, it automatically
receives an assignment of Unassigned. You must manually assign the new
drive to Hot Spare if the new drive is to serve as a hot spare.
Most systems only use one physical drive to serve as a hot spare. However,
there is no restriction on the number of hot spares in the system, though
every additional hot spare uses another physical drive and lessens storage
capacity. Any and all drives may serve as hot spares. There is no
requirement to have a hot spare on the system at all.
To assign a hot spare:
1
Click the Storage tab, then select Physical Drives.
2
Click Actions, then select Assign Hot Spares.
3 A picture representing all of the physical drives in the system appears.
Each drive is represented by a graphic of a drive bay. Drive bays
containing unassigned drives or hot spare drives are selectable. All other
drive bays are not selectable.
4 Select the drives to be used as hot spares by clicking on them.
5
Click OK.

storage capacity or replacing a failed hard drive.
