Changing Capacity and RAID Levels
The integrated HP NetRAID controller can expand capacity and change RAID
levels of logical drives without powering down the server.
• Online Capacity Expansion: You can add a physical drive to a RAID 0,
3, or 5 logical drive. This can be an online operation if you are running
Novell NetWare 4.2 or 5 or Microsoft Windows NT or Windows 2000.
(Preparations for capacity expansion must be made, as described in
Chapter 7, "Preparing for Online Capacity Expansion.")
• Online Changes to RAID Levels: You can convert a RAID 1, 3, or 5
logical drive to RAID 0.
NOTE You cannot perform online conversions of logical drives that
span arrays (RAID level 10, 30, or 50).
