3ware Escalade ATA RAID Controller User Guide the array to be fully redundant, as it takes longer to initialize an array than it takes to write zeros to the array. Caution: When running in initializing mode the array is not redundant. You cannot remove any drive. For RAID 1 or 10 Arrays RAID 1 and 10 arrays are not profiled when created, or initialized after booting into the OS. When the firmware receives the first verify request, given that the array was never initialized, the initialization will then begin. Any subsequent verify operations will then perform the verification of the array (check data consistency). An AEN will inform the user that the first verify is actually an initialization. Specifying a Hot Spare The Escalade ATA RAID Controller gives you the option to specify a hot spare from one of your Available Drives. If a hot spare is specified and the array degrades, an event notification will be generated. The hot spare will dynamically replace the failed drive in an array without user intervention. Select a hot spare by navigating to an Available Drive. The Toggle Hot Spare verbiage at the bottom of the screen will be black if the drive can be used as a hot spare. Enter s to select the hot spare or to disable the hot spare if it is already enabled. 54 www.3ware.com
