initiAlizAtion
Technically speaking, Initialization is a foreground activity, as you cannot access a logical drive while it
is initiating.
Initialization is normally done to logical drives after they are created from a disk array. Initialization sets
all data bits in the logical drive to zero. The action is useful because there may be residual data on the
logical drives left behind from
earliercongurations.Forthisreason,Initializationisrecommendedwheneveryoucreatealogical
drive.
See “Initializing a Logical Drive” on page 77.
