Setting Up Your Array For Capacity Expansion - HP D5970A - NetServer - LCII Installation And Configuration Manual

Chapter 7

Setting Up Your Array for Capacity Expansion

This section makes the following assumptions:
You have already installed your drives and configured your adapter as
discussed in Chapter 4. You should have created only one logical drive
per array.
For example, you might have four physical drives of 4 GB each connected
to the adapter. You might have configured these four drives as a single
RAID 5 logical drive. This produces a logical drive with 12 GB of real
storage capacity, with 4 GB used for parity.
You have initialized your logical drives.
NOTE It is important to initialize your logical drives because, if the
drives have been previously configured under an operating
system, there may be residual partition/format information
that can subsequently cause misrepresentation of logical drives
under the Windows NT Disk Administrator.
You have already installed Windows NT as discussed in Chapter 5.
