Preparing for Online Capacity Expansion

This section describes how to enable Virtual Sizing and set up your partitions to
permit easy capacity expansion.
For NetWare installations, plan ahead and consider your storage use. Since
NetWare permits only one NetWare partition per logical drive, make the
NetWare partition the size of the virtual logical drive in advance so that you can
expand that volume. Under NetWare, you cannot grow a partition, but you can
add additional segments within an existing partition. The added segments can be
"joined" to be part of the same volume, or they can be made into separate
volumes.
NOTE
If NetWare must be installed on the disk array, create a single
logical drive with Virtual Sizing enabled. Create a DOS
partition of 500 MB or less for booting. NetWare volumes can
then be added after the DOS partition on the same logical
drive. The unused space on the partition can be used later for
capacity expansion. Be sure to follow the precautions above.
In most installations, the operating system is installed on a SCSI drive connected
outside of the HP NetRAID system. The following steps are necessary to prepare
your array for capacity expansion.

Setting Up Your Array for Capacity Expansion

This section makes the following assumptions:
You have already configured your HP NetRAID system as discussed in
Chapter 5. You should have created only one logical drive per array.
For example, you might have four physical drives of 4 GB each. You
might have configured these four drives as a single RAID 5 logical drive.
This will produce a logical drive with 12 GB of real storage capacity, with
4 GB used for parity.
You have initialized your logical drives.
