Accessory Board Installation Guidelines
The following sections provide guidelines for installing PCI accessory boards into
the HP Netserver 2000r.
IRQ Settings
The HP Netserver uses the Plug and Play feature of the PCI board to automatically
assign IRQ settings to its resources.
Boot Priority
The HP 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 board’s boot
priority is determined by its PCI slot location. See Figure 5-1.
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 HP Netserver scans for a boot device starting at device ID 0 and works up
from there.
By default the HP 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 slots 1, 2, and 3 (32-bit 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-4M PCI board in the HP Netserver LP 2000r. 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.
