Installing Mass Storage Devices

Introduction

The HP Server comes standard with a DVD and a floppy diskette drive. The internal mass storage
cages support a maximum of two hot swap drive carriers. Each carrier can house a standard one inch
high by three and half inch wide SCSI-2 or SCSI-3 hard drive. The internal SCSI drives are mounted
to the carriers using four screws.

Mass Storage Guidelines

•
General Guidelines
Use care when unpacking and handling the SCSI disk drives.
◊
The hard disk drives are very susceptible to mechanical shock and can be easily damaged
by a drop as short as one-quarter of an inch. If the drop would crack an egg, it will damage
the drive.
Do not stack drives.
◊
The HP Server is internally limited to 2 SCSI disk drives
◊
•
IDE Devices
The diskette drive and DVD drive are standard on all models of the HP Server. They are
◊
housed in two piece drive carrier assemblies that rest on the chassis surface. They are
accessible when the top cover is removed. See Figures 4-3 and 4-4.
The Legacy I/O board contains the PCI-enhanced IDE interface with two IDE buses. The
◊ ◊ ◊ ◊
primary IDE 0 bus supports the diskette drive and the secondary IDE 1 bus supports the
DVD drive.
Refer to "System Board Layout" in Appendix A, "Specifications."
•
SCSI Device Selection
A Qlogic ISP12160A Ultra3 SCSI chip is a highly integrated bus master, dual-channel
◊ ◊ ◊ ◊
SCSI I/O processor for SCSI initiator and target applications. The chip supports dual
channel, Ultra3 (160) SCSI functionality and is pin compatible with QLogic's ISP12160
Ultra3 SCSI processor as well as QLogic's ISP1280 dual SCSI processor.
Use only low-voltage differential (LVD) SCSI devices.

Boot Priority

The HP Server's boot order should be considered when selecting a PCI slot on the system board. 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 set by its slot location in the boot order.
By default the HP Server searches for boot devices in this order:
1. SCSI
2. PM
3. SM
