If the Chunk Size screen displays, select the chunk size and press
<Enter>.
The chunk size is the amount of contiguous data that is written to
an array member before moving to the next member of the array.
To determine the appropriate chunk size, refer to your operating
system documentation. For example, the default chunk size for
Windows NT and many other operating systems is 64KB. If you are
using the array for a database with very small records, you may
want to use a smaller chunk size.
If the array you are creating is a RAID 3, RAID 4, RAID 5, RAID 50,
or Mirrored, the Array Init Options screen displays. The current
option has an * next to it.

If the Array Init Options screen displays, select the option you want
and press <Enter>.
- Offline Initialization: Using this option means you must wait for
the array initialization process to finish before using the array.
It uses the zero method to create the array, which is faster than
the verify method.
- Online Initialization: Using this option lets you begin using the
array immediately after creating it, while the array initialization
process runs. It uses the verify method to create the array,
which takes longer than the zero method.
12.
The system prompts you to confirm array creation. Select
Yes
and
press <Enter>.
A message notifies you that the array is being created and shows
the progress of the initialization process. The array initialization
process takes from several minutes to more than an hour
