the array goes into initialization mode after a delay of up to ten minutes. The
advantage of doing this is that the RAID 5 can be used immediately, although it
will not be fault tolerant until the initialization is complete. The disadvantage of
doing this is that it will take longer for the array to be fully redundant, as it takes
longer to initialize an array than it takes to write zeros to the array.
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 PRO 16/8 RAID DVR 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.
