The value that you enter for this option
specifies the RAID level of the logical drive.
When the Action mode is Configure, and the
Method mode is Auto, ACU automatically selects the highest RAID
level that the controller and drive configuration can support
except RAID 50 or RAID 60. To specify RAID 50 or 60 for a
controller that supports either of these RAID levels, use the
Custom setting. In this case, you must also specify the number of
parity
groups.
When the Action mode is Reconfigure, the
default value is the existing RAID level for that logical drive. If
you specify a different RAID setting, then ACU either ignores the
new setting (when Method mode is Auto), or attempts to migrate the
logical drive to the specified RAID level (when Method mode is
Custom).
