Chapter 6 Capacity Expansion

118

In most installations, the operating system is installed on a SCSI drive connected

outside of the HP NetRAID system. However, NetWare 5 can reside on a disk

array in the HP NetRAID system to achieve redundancy.

Preparation Steps for NetWare 5

This section tells you how to enable Virtual Sizing and set up your partitions to

permit easy capacity expansion. It assumes that you have already installed

NetWare 5.

The following steps are necessary to prepare your logical drive for online capacity

expansion:

I. Connect drives to the HP NetRAID Series adapter or integrated

HP NetRAID controller

II. Configure the HP NetRAID Series adapter or integrated HP NetRAID

controller

III. Disable Virtual Sizing in HP NetRAID Express Tools

I. Connect Drives

Connect physical drives to the HP NetRAID Series adapter or integrated

HP NetRAID controller. For example, you might have four drives of 4 GB each

connected to the adapter.

II. Configure the HP NetRAID Series Adapter or Integrated HP NetRAID Controller

NOTE The Online Capacity Expansion feature is supported only on

arrays that contain just one logical drive each.

Configure your adapter and create your logical drives. (This can be done in either

HP NetRAID Config or in HP NetRAID Express Tools. See "HP NetRAID

Express Tools" or "HP NetRAID Config" for complete instructions.) Save your

configuration and initialize your logical drives.

NOTE It is important to initialize your logical drives. If the drives

have been previously configured under an operating system,

there can sometimes be residual partition/format information

which subsequently causes misrepresentation of logical drives

under NetWare 5.

For example, your array of four drives (of 4 GB each) might be configured as a

single RAID 5 logical drive. This produces a logical drive of 12 GB of real

storage capacity, with 4 GB used for parity.
