Chapter 4 HP NetRAID Express Tools Disable/Enable BIOS Option This option disables or enables the BIOS firmware. The default setting is Enabled. If the BIOS is disabled, DOS cannot read logical drives, and you cannot boot from RAID. You might disable the BIOS in order to boot off the embedded SCSI instead of the adapter. Change Adapters Option If you have more than one HP NetRAID Series adapter installed, or if you have an integrated HP NetRAID controller with one or more HP NetRAID Series adapters installed, use this selection to choose which adapter you want to affect.

The two settings for the onboard tone generator are described below. ◊ Enable/Disable Alarm: Choose this option to enable or disable the onboard tone generator. The default setting is Enabled. ◊ Silence Alarm: This setting stops the alarm when it goes off. For complete information, see Chapter 8, "Alarm Control and Audible Warnings." C Configuring Arrays and Logical Drives Each configuration method requires a different level of user input. The general flow of operations for array and logical drive configuration is described below. 1. Designate global hot spares (optional). 2. Create arrays using the available physical drives. 3. Initialize the new logical drives. Designating Drives as Global Hot Spares Global hot spares are physical drives that are powered up along with the RAID drives and remain in a standby state. If a disk drive used in any logical drive fails, a hot spare can automatically take its place. The data on the failed drive is reconstructed onto the hot spare. Hot spares can be used for RAID levels 1, 3, 5, 10, 30, and 50. Each adapter supports up to eight hot spares. HP NetRAID Express Tools lets you create global hot spares.
