3. Click one of the following configuration modes:
◊ Select Custom if you want to define the arrays and logical drives and
set their parameters.
◊ Select Automatic if you want the HP NetRAID Assistant Wizard to
define the arrays and logical drives and set their parameters for you
automatically.
When you select Automatic mode, you can toggle the Redundancy
check box at the bottom of the window. If the Redundancy box
contains a check mark, the arrays are automatically configured with
redundant logical drives if possible. They are assigned RAID levels of
0, 1, or 5, depending on the number and capacities of the physical
drives. If the Redundancy box is empty, all logical drives are
configured as RAID 0, which are not redundant. Automatic mode uses
the following rules to define arrays and logical drives.
∗
Automatic mode scans the physical drives, starting at SCSI ID 0 on
Channel 0, and groups the physical drives by capacity, with up to
five drives in an array.
∗
Each array is defined as a single logical drive, and array spanning is
not used.
∗
For each array, the system looks to see if you have asked to
implement redundancy (checked the Redundancy box). If you are
not using redundancy, all logical drives are assigned RAID level 0.
