The server always boots from the hard drive controller identified as primary.
The System Configuration Utility automatically assigns the primary controller
unless you manually change the selection. The controller ordering selected
during configuration also dictates the order in which some operating systems
load hard drives. The system boots from the device with the lowest SCSI ID.

SCSI Configuration Notes
A SCSI configuration supports various devices such as hard drives, tape
drives, and CD-ROMs. You can easily add or remove SCSI devices from a
SCSI chain without concern for their order or sequential numbering.
Configuration Guidelines
Boot from the CD-ROM Drive in the Compaq ProLiant 5000 Servers.
Each SCSI device must have a unique SCSI ID.
A SCSI controller can daisy-chain up to seven hard drives, CD-ROM
drives, scanners, tape drives, and/or other SCSI devices, with IDs ranging
from 0 to 6. The ID number 7 is reserved for the controller. ID number 0
is the lowest priority device.
You can have gaps in the SCSI chain, as long as you terminate the
chain. Various forms of SCSI terminators exist. Some devices have
jumpers to terminate the chain. In other cases, the drive controller has
connectors to terminate the chain. Special terminating connectors are
also available. Do not terminate a chain prematurely. If you do so, the
drive controller might not access any devices that follow the first
terminated device in the chain.
