creatInG a DISk array wIth the wIzarD
The Wizard creates disk arrays and logical drives automatically. It has four options.
• Automatic – Creates a new disk array following a default set of parameters. Creates a hot spare drive for
allRAIDlevelsexceptRAID0,whenveormoreunconguredphysicaldrivesareavailable.Youcanaccept
or reject the proposed arrangement but you cannot modify it. See instructions in "Wizard - Automatic
