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. 107
