Installing Internal Drives
To configure the SCSI devices that you install in a non-disk-array
model, use the SCSISelect utility program. See “Using the
SCSISelect Utility Program” on page 303. For disk-array models,
use the ServeRAID configuration program described in Chapter 3,
“Configuring the Disk Array” on page 77.
There are two types of SCSI devices: wide and narrow. You must
use 16-bit cables to attach wide devices. Use 8-bit cables to attach
narrow devices. Wide device IDs can be set to any number from 0
to 15. Narrow devices can have their IDs set only from 0 to 7. The
preinstalled CD-ROM drive in bay A is a narrow device.
Two devices on the same bus (internal or external) cannot have the
same ID; however, your server can use the same ID for an internal
device and an external device. The primary partitions on SCSI
drives that are connected to the internal bus on a given adapter are
assigned drive letters before the external drives that are connected
to the same adapter are assigned drive letters. If multiple adapters
are installed in your server, the drives that are connected to the
adapter in the lowest number expansion slot are assigned drive
letters first.
