Boot Order
The slot you choose for the adapter could affect the boot order of your devices.
The boot order differs among systems, so consult the mass storage section of your
system documentation for boot order information. (If you need to prevent booting
from the adapter, follow the instructions in Chapter 6, Step M during the
installation.)
Special Instructions on LX Pro and LXr Systems
If your system is set with normal boot order, follow these recommendations:
• If you have more than one HP NetRAID Series adapter, put all adapters
on the same PCI bus. In the LX family of systems, slots P1, P2, and P3 are
on Bus 0. Slots P4, P5, and P6 are on Bus 1.
• Do not put a HP NetRAID-3Si or HP NetRAID-1Si adapter in PCI slot 4
if you want it to be your boot device.
• If you have an HP NetRAID adapter that you want to be the first boot
device, put it in the first or lowest PCI slot available.
If your system is set with on-board boot order, follow this recommendation:
• Put all HP NetRAID Series adapters in the same bus.
Sharing IRQs
The adapter can share IRQs. To determine the implications of IRQ sharing for
slot selection, refer to your system documentation and the NOS Installation
Guide in the HP NetServer Navigator CD-ROM.
Cable Management
Cable management is another factor to consider when choosing a slot for the
adapter. Try to avoid having cables block access to other I/O cards in the system.
Log the adapter’s PCI slot on Worksheet A.
