The device is attached to the integrated SCSI
controller.
SCSI IDs:
Each SCSI device that is connected to an
individual channel of a SCSI controller needs a unique
identification (ID) so that the controller can identify the
devices and ensure that different devices do not attempt to
transfer data at the same time. If you need to set IDs for
SCSI devices, refer to the instructions that come with
those devices.
The server automatically sets SCSI IDs for hot-swap hard
disk drives. The SCSI ID assigned to each hot-swap bay
is shown on the server beside the bay and in the
illustrations in “Internal drive bays” on page 124. The
server uses the hard disk drive SCSI IDs to send status
information to the indicator lights above each hot-swap
bay.
The SCSI backplane in the server supports up to six
hot-swap bays.
The processing sequence for SCSI devices proceeds from
the lowest SCSI ID to the highest (0 to 5, then 8 to 15).
Termination (internal SCSI devices):
SCSI
buses must be terminated at each end. The ends of the
SCSI buses in the server are already terminated.
All the hot-swap drives in the server have automatic
termination and the SCSI controller provides termination at
the other end of the SCSI bus.
You must disable termination on any SCSI devices that
you install in the non-hot-swap bays. Refer to the
information that come with the SCSI device for instructions
about setting device jumpers or switches that control
termination.
Preinstallation steps (all bays):
Before you
install drives in the server, verify that you have all the
cables and any other equipment specified in the
documentation that comes with the internal drive. You
might also need to perform certain preinstallation activities.
Some of the steps are required only during the initial
installation of an option.
Before you begin:
Ÿ
Read “Safety information” on page 230.
Ÿ
Read the documentation that comes with the
internal drive.
1. Choose the bay in which you want to install the drive.
2. Check the instructions that come with the drive to see
if you need to set any switches or jumpers on the
drive.
