Assigning Hot Spares
A hot spare is an extra, unused disk drive that is part of the disk subsystem. It is usually
in standby mode, ready for service if a drive fails. Hot spares permit the replacement of
failed drives without system shutdown or user intervention. If a disk drive used in a
RAID logical drive fails, a hot spare will automatically take it place and the data on the
failed drive is rebuilt on the hot spare.
Global Hot Spares
To make a hot spare, click on a physical drive that is in Ready status. All physical
drives appear in one of the Physical Devices windows.
If you inadvertently click on a drive icon for a physical drive that you do not want to
make a hot spare, click on it again to deselect the drive.
Drag and drop the selected physical drive into the global hot spare pool.
Reclaiming Hot Spares While Running the Wizard
Select one or more hot spares and click on the Reclaim button on the Array Definition
screen. The selected hot spare physical drives are changed to Ready drive status.
Reclaiming Hot Spares During Normal Operation
To change a drive from a hot spare to a drive in the Ready state, Select the drive and
click the right mouse button. Choose Tools and choose Fail Drive. The drive will return
to the Ready state.
