There may be instances when you always want the computer to wait
for the drive to write all the data to disk before going on to its next
task. For this case, you must disable the write cache. To disable the
write cache, select disable from the array’s Write Cache State
selection. The default for Write Cache State is enable.
Confirm array configuration
Select the OK button to confirm creating the array or Cancel to
reject it. The array is not actually created and no data will be over-
written until you have finished making all your changes and select
the F8 key.
For RAID 5 Arrays
Because of the Read-Modify-Write operations, zeros are first writ-
ten to all drives in the array before the array is functional. The
screen shown in Figure 12 appears after selecting OK to confirm
array creation.
If the write-zeros operation is aborted by the user for any reason the
unit will go into initializing mode when restarted. This mode scans
the entire array to verify parity. If coherency problems appear the
parity will be corrected to match the data found on that stripe.
Caution:
When running in initializing mode the array
is not redundant. You cannot remove any drive
.
For RAID 1 or 10 Arrays
Drives are dynamically profiled, specifically for your brand of
drive, after selecting OK to confirm array creation. This is done to
customize the stripe size (for RAID configurations offering variable
striping) and seek algorithms.
