Using Auto Configuration
In Auto Configuration, HP NetRAID and HP NetRAID-1 use the following configuration guidelines
in the following sequence:
1. Gather drives with the same capacity into groups of five, four, or three. These groups become
arrays associated with RAID level 5 logical drives.
2. Gather pairs of drives with the same capacity together. These pairs become arrays associated
with RAID 1 logical drives.
3. Configure any remaining single disk drives as arrays associated with RAID 0 logical drives.
