This isdone by using the S key on the selected drive. Leaving a drive undesignatedresults in it becoming a JBOD drive. JBOD drives become available to theoperating system as distinct volumes, and, consequently, they cannot be des-ignated as spares and cannot be used to rebuild degraded arrays at a later time.If a spare is designated in the BIOS screen, the designation and configurationis in effect from this point on. The spare drive will be displayed as a Hot Sparein the 3DM Configuration page.3DM Configure PageIn order to designate an available drive as a spare from the 3DM Configurepage, you select a drive that is not a JBOD drive or part of an existing array.To designate a drive as a Hot Spare from this page, you must use one of thetwo following methods:Replacing a Defective Drive with a SpareReplace the drive at the operating system level while the system is powered.This should only be done with an approved and recognized hot swap drive-carrier.
