HP Netserver LP 1000r User Guide

Chapter 5 Installing Additional Boards

Accessory Board Installation Guidelines

The following sections provide the guidelines necessary to install a PCI accessory

board into the HP Netserver LP 1000r.

IRQ Settings

The IRQ settings are automatically assigned and don’t require user intervention.

The HP Netserver uses the Plug-and-Play feature of the PCI board to correctly

assign its resources automatically.

Boot Priority

The Netserver’s boot priority (BIOS search order for a boot drive) should be

considered when selecting a boot device. This is especially important if you are

installing a board that requires an early number in the boot order.

The embedded SCSI controller consists of two channels, A and B. Channel A is

used to control the internal Hot Swap SCSI drives. Channel B is used to control

the external SCSI devices, including a backup tape drive. On each SCSI channel,

the Netserver scans for a boot device starting at device ID 0 and works up from

there.

By default the Netserver searches for boot devices in this order:

1. IDE CD-ROM drive

2. Flexible disk drive

3. SCSI A channel (Hot Swap SCSI HDD)

4. SCSI B channel (external SCSI devices)

5. PCI slot P1 (32- or 64-bit slot)

6. Network connection

Installing a Disk Array Controller Board

Adding a disk array controller board provides additional fault tolerance to your

internal or external mass storage devices. HP recommends installing the HP

NetRAID-1Si,-1M, or-2M controller board in the HP Netserver LP 1000r. When

installing a disk array controller board, you may alter the Netserver’s boot order to

allow the Netserver to boot off one of the array’s drives. This boot order can be

changed under the Configuration menu of the Netserver’s (BIOS) Setup Utility

and in the SCSI Configuration Utility.
