7 Preparing for Online Capacity Expansion Step N. Prepare for Online Capacity Expansion The HP NetRAID Online Capacity Expansion feature allows you to add new storage capacity to drives controlled by an HP NetRAID Series adapter without rebooting the server. Online Capacity Expansion has these restrictions: • Online Capacity Expansion has a maximum capacity of 82 GB. Online Capacity Expansion is not available if your physical capacity exceeds 82 GB. • You can use Online Capacity Expansion with any logical drive of RAID level 0, 3, or 5. Capacity expansion is an offline operation only for logical drives of RAID levels 10, 30, or 50. • You cannot use Online Capacity Expansion with an array that contains more than one logical drive. The logical drive must be the only logical drive in the array. • Online Capacity Expansion is supported only for the Novell NetWare and Microsoft Windows NT operating systems. You cannot use Online Capacity Expansion with SCO UNIX, SCO UnixWare, IBM OS/2, or Banyan VINES. This chapter explains how to prepare logical drives for future online expansion. The HP NetRAID Series User Guide in Information Assistant describes how to actually expand capacity. NOTE If you are using I2O drivers, some special precautions exist. See the I2O information on the following web site: www.hp.com/go/netserver 81

You can use Online Capacity Expansion with any logical drive of RAID
level 0, 3, or 5. Capacity expansion is an offline operation only for logical
drives of RAID levels 10, 30, or 50.
•
You cannot use Online Capacity Expansion with an array that contains
more than one logical drive. The logical drive must be the only logical
drive in the array.
•
Online Capacity Expansion is supported only for the Novell NetWare and
Microsoft Windows NT operating systems. You cannot use Online
Capacity Expansion with SCO UNIX, SCO UnixWare, IBM OS/2, or
Banyan VINES.
This chapter explains how to prepare logical drives for future online expansion.
The
HP NetRAID Series User Guide
in Information Assistant describes how to
actually expand capacity.
