Chapter 7 Preparing for Online Capacity Expansion This section describes preparation for online capacity expansion for logical drives operating in Basic Disk Mode under Windows 2000. (Capacity cannot be expanded online for logical drives operating in Dynamic Disk Mode.) Preparation for capacity expansion under Windows 2000 operating in Basic Disk Mode is simply to leave virtual sizing disabled (the factory default), or to disable it if it has been enabled. To actually expand capacity online in Basic Disk Mode, you will create a new volume with a new drive letter. Capacity can be expanded online again in the future. Refer to the HP NetRAID Series User Guide and your Windows 2000 documentation for information about adding a new volume online to expand capacity online. Preparation Steps for Windows 2000 This section makes the following assumptions: • You have already configured your HP NetRAID system as discussed in Chapter 5, "Installation and Configuration." You should have created only one logical drive per array. For example, you might have four physical drives of 4 GB. 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 2000 Disk Management. • You have already installed Windows 2000 as discussed in Chapter 6, "HP NetRAID Software." • The logical drive that you plan to expand must be running in Basic Disk Mode in Windows 2000. • You have already installed HP NetRAID Assistant, as discussed in Chapter 6, "HP NetRAID Software." The version of HP NetRAID Assistant must be the same version or newer than the version on the HP NetRAID Navigator CD-ROM shipped with your HP Netserver. 95

Chapter 7
Preparing for Online Capacity Expansion
95
This section describes preparation for online capacity expansion for logical drives
operating in Basic Disk Mode under Windows 2000. (Capacity cannot be
expanded online for logical drives operating in Dynamic Disk Mode.)
Preparation for capacity expansion under Windows 2000 operating in Basic Disk
Mode is simply to leave virtual sizing disabled (the factory default), or to disable
it if it has been enabled.
To actually expand capacity online in Basic Disk Mode, you will create a new
volume with a new drive letter. Capacity can be expanded online again in the
future. Refer to the
HP NetRAID Series User
Guide and your Windows 2000
documentation for information about adding a new volume online to expand
capacity online.
Preparation Steps for Windows 2000
This section makes the following assumptions:
•
You have already configured your HP NetRAID system as discussed in
Chapter 5, "Installation and Configuration." You should have created only
one logical drive per array.
For example, you might have four physical drives of 4 GB. 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 2000 Disk Management.
•
You have already installed Windows 2000 as discussed in Chapter 6,
"HP NetRAID Software."
•
The logical drive that you plan to expand must be running in Basic Disk
Mode in Windows 2000.
•
You have already installed HP NetRAID Assistant, as discussed in
Chapter 6, "HP NetRAID Software." The version of HP NetRAID
Assistant must be the same version or newer than the version on the
HP
NetRAID Navigator CD-ROM
shipped with your HP Netserver.
