Chapter 6 Capacity Expansion In most installations, the operating system is installed on a SCSI drive connected outside of the HP NetRAID system. However, NetWare 5 can reside on a disk array in the HP NetRAID system to achieve redundancy. Preparation Steps for NetWare 5 This section tells you how to enable Virtual Sizing and set up your partitions to permit easy capacity expansion. It assumes that you have already installed NetWare 5. The following steps are necessary to prepare your logical drive for online capacity expansion: I. Connect drives to the HP NetRAID Series adapter or integrated HP NetRAID controller II. Configure the HP NetRAID Series adapter or integrated HP NetRAID controller III. Disable Virtual Sizing in HP NetRAID Express Tools I. Connect 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 the HP NetRAID Series Adapter or Integrated HP NetRAID Controller NOTE The Online Capacity Expansion feature is supported only on arrays that contain just one logical drive each. Configure your adapter and create your logical drives. (This can be done in either HP NetRAID Config or in HP NetRAID Express Tools. See "HP NetRAID Express Tools" or "HP NetRAID Config" for complete instructions.) Save your configuration and initialize your logical drives. NOTE It is important to initialize your logical drives. If the drives have been previously configured under an operating system, there can sometimes be residual partition/format information which subsequently causes misrepresentation of logical drives under NetWare 5. For example, your array of four drives (of 4 GB each) might be configured as a single RAID 5 logical drive. This produces a logical drive of 12 GB of real storage capacity, with 4 GB used for parity. 118
