Chapter 2 HP NetRAID Assistant Figure 2-4. HP NetRAID Assistant Wizard Starting Window 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. 29
