Chapter 6 Capacity Expansion Precautions When using the Online Capacity Expansion feature, it is important that you do not create volumes that exceed the actual physical capacity. If you attempt to do this under Windows NT, the format operation will fail. If you extend an existing partition into virtual space, this is detected upon rebooting. In either case, be sure to use no more than the actual available physical capacity. Capacity of the logical drive can be checked with the HP NetRAID Assistant under Windows NT. The Online Capacity Expansion feature cannot be used if a logical drive spans multiple arrays. Each array can contain only one logical drive. Reconstruction (for the purposes of adding a drive to an existing array) can only be done on an array having a single logical drive. It is also important to plan future storage expansion into your installation. This will ensure that you can easily expand capacity without backup/restore operations or reconfiguration. Preparation Steps for Windows NT This section repeats information found in the HP NetRAID Series Installation and Configuration Guide and in the HP NetServer Integrated NetRAID Controller Configuration Guide. It tells you how to enable Virtual Sizing and set up your partitions to permit easy capacity expansion. The following steps are necessary to prepare your array for capacity expansion. I. Connect disk drives to HP NetRAID II. Configure HP NetRAID III. Enable Virtual Sizing in HP NetRAID Express Tools IV. Start Windows NT and enter the Disk Administrator V. Partition and format the drive under Windows NT I. Connect Disk 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 HP NetRAID Configure your HP NetRAID Series adapter or integrated HP NetRAID controller and create a logical drive. (This can be done in either HP NetRAID Assistant or in HP NetRAID Express Tools. See Chapter 2, "HP NetRAID Assistant," or Chapter 4, "HP NetRAID Express Tools," for complete instructions.) Save your configuration and initialize your logical drives. 125

Precautions
When using the Online Capacity Expansion feature, it is important that you do
not
create volumes that exceed the actual physical capacity. If you attempt to do this
under Windows NT, the format operation will fail. If you extend an existing
partition into virtual space, this is detected upon rebooting. In either case, be sure
to use no more than the actual available physical capacity. Capacity of the logical
drive can be checked with the HP NetRAID Assistant under Windows NT.
The Online Capacity Expansion feature cannot be used if a logical drive spans
multiple arrays. Each array can contain only one logical drive. Reconstruction (for
the purposes of adding a drive to an existing array) can only be done on an array
having a single logical drive. It is also important to plan future storage expansion
into your installation. This will ensure that you can easily expand capacity without
backup/restore operations or reconfiguration.
Preparation Steps for Windows NT
This section repeats information found in the
HP NetRAID Series Installation and
Configuration Guide
and in the
HP NetServer
Integrated NetRAID Controller
Configuration Guide
. It tells you how to enable Virtual Sizing and set up your
partitions to permit easy capacity expansion.
The following steps are necessary to prepare your array for capacity expansion.
I.
Connect disk drives to HP NetRAID
II.
Configure HP NetRAID
III.
Enable Virtual Sizing in HP NetRAID Express Tools
IV.
Start Windows NT and enter the Disk Administrator
V.
Partition and format the drive under Windows NT
I. Connect Disk 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 HP NetRAID
Configure your HP NetRAID Series adapter or integrated HP NetRAID controller
and create a logical drive. (This can be done in either HP NetRAID Assistant or in
HP NetRAID Express Tools. See Chapter 2, "HP NetRAID Assistant," or
Chapter 4, "HP NetRAID Express Tools," for complete instructions.) Save your
configuration and initialize your logical drives.
