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.
Alarm Control Option
This option is available for HP NetRAID-1Si and HP NetRAID-3Si. 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

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. Users with
Microsoft Windows NT and Windows 2000 can use HP NetRAID Assistant to
