6 Capacity Expansion
With HP NetRAID, you can expand capacity at any time by adding one or more
new hard disks to your system. If you prepared for Online Capacity Expansion as
described in the HP NetRAID Series Installation and Configuration Guide or the
HP NetServer Integrated NetRAID Controller Configuration Guide, you can add
disks to an existing logical drive without restarting the HP NetServer.
Online Capacity Expansion has these restrictions:
•
You can use Online Capacity Expansion with any logical drive of RAID
level 0, 3, or 5. (Capacity expansion is an offline operation for logical
drives of RAID levels 10, 30, or 50. It cannot be done for RAID 1 logical
drives because mirroring requires exactly two physical drives.)
•
You cannot use Online Capacity Expansion with an array that contains
more than one logical drive. The logical drive being expanded must be the
only logical drive in the array.
•
Online Capacity Expansion is supported only for the NetWare 4.2,
NetWare 5, Windows NT, and Windows 2000 operating systems. (You
cannot use Online Capacity Expansion with IBM OS/2, SCO OpenServer,
or SCO UnixWare.)
This chapter contains separate sections covering capacity expansion under
NetWare 4.2, NetWare 5, Windows NT, and Windows 2000. Each of these
sections discusses online and offline capacity expansion.
For information about offline capacity expansion under another network operating
system (NOS), refer to your NOS documentation.
Capacity Expansion under NetWare 4.2
This section describes how to expand disk capacity under Novell NetWare 4.2
after the system has been in operation for a time. This section is divided into these
parts:
•
About Online Capacity Expansion under NetWare 4.2 describes the
Online Capacity Expansion feature. This feature allows new storage
capacity to be added to an existing logical drive and put online for use
without restarting the server.
