Changing Capacity and RAID Levels

HP NetRAID Series adapters 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
Microsoft Windows NT or Novell NetWare; otherwise, capacity expansion
is an offline operation only. (Preparations for capacity expansion must be
made, as described in Chapter 6, "Preparing for Online Capacity
Expansion.")
Online Capacity Reduction: You can remove a physical drive from a
RAID 1, 3, or 5 logical drive as part of an online operation.
Online Changes to RAID Levels: You can convert a RAID 1, 3, or 5
logical drive to RAID 0.

About This Guide

This guide is intended to be used together with the HP NetRAID Series
Installation Road Map. This guide provides detailed explanations of instructions
found in the road map.
This HP NetRAID Series Installation and Configuration Guide will help you
install your HP NetRAID, HP NetRAID-1, or HP NetRAID-3Si adapter, and plan
the configuration. It guides you through power-up, launching the HP NetServer
Navigator software, making the initial configuration of the adapter, and
installing a NOS-specific configuration utility. It contains a glossary, and its
appendices contain sample cabling diagrams and worksheets to use in planning

the configuration of physical and logical drives.
Fill in the worksheets in Appendix C as you read this guide and make your
configuration decisions. The worksheets contain the information you need to
enter into the HP NetRAID Assistant configuration utility launched by HP
Navigator. The pencil icon in the margin is a reminder to log your configuration
choices on the worksheets.
You cannot perform online conversions of logical drives that
span arrays (RAID level 10, 30, or 50).
