Making Hot Spare

The Universal RAID Utility can make a Hot Spare to be replaced with a Physical Device in which a failure occurs.

Hot spares can have the following two modes.

Mode Description

Global (Hot Spare) Available as a Hot Spare of every Disk Array for a single RAID Controller.

Dedicated (Hot Spare) Available as a Hot Spare of a specific Disk Array for a single RAID Controller.

In either mode, note the following to have a Hot Spare operate normally.

The Physical Device used for rebuild should have the same the same capacity, rotation speed, and other specification as

the defected Physical Device.

The Physical Devices with the different size must be used as Dedicated Hot Spares.

A Physical Device in which a S.M.A.R.T. error is detected cannot be used as a Hot Spare.

The maximum number of Hot Spares that can be created is 8 for N8103-109/128/134/135
