Modes of Hot Spares

The Easy Configuration can only make Dedicated Hot Spares but cannot make Global Hot Spares.

If more than one Logical Drive is created, the Dedicated Hot Spare can be used for all Logical Drives to be

created.

Ex.: If Physical Devices 1 - 7 are used in Easy Configuration to create two Logical Drives and a single Hot

Spare, the Hot Spare will be the Dedicated Hot Spare for each Logical Drive.

Figure 20 Making Dedicated Hot Spare in Easy Configuration 1

Ex.: If Physical Devices 1 - 7 are used in Easy Configuration to create two Logical Drives and two Hot Spares,

Physical Devices 7 will be the Dedicated Hot Spares for both Logical Drives #1 and #2.
