4.6 Setting Channel Configuration
channel operation mode to host or drive, enable or disable the
channel termination, set its SCSI ID, set the transfer clock rate
for synchronous communication, and select the transfer width.
The following describes the user-configurable parameters:
♦
Channel Mode. This parameter sets the operation mode
of a particular channel on the SCSI-to-SCSI controller. It
configures the operation mode to either host or drive,
where a host channel is used when connecting to a host,
while a drive channel is for connecting to SCSI drives.
Any SCSI channel on the SCSI-to-SCSI controller can
serve as either a host or a drive channel. Channel 0 is the
default host channel with SCSI ID number 0.
For a PCI-to-SCSI controller, this parameter is
permanently set to Drive.
♦
Termination. This parameter enables or disables SCSI
channel termination. SCSI cables must be properly
terminated at both ends; that is, when connecting one end
of a SCSI cable to a channel, the termination of the
channel must be enabled. Note that the other end of the
cable must also be properly terminated.
You can terminate the other end of the cable by installing
or enabling termination on the SCSI drive farthest from the
controller or by installing an external terminator on the end
connector. The latter method is recommended so that
removal of the drives will not affect cable termination. All
other terminators must be removed or disabled making
sure that only one terminator is installed on each end.
♦
SCSI ID. This parameter sets the SCSI ID of the channel.
Each channel must have a unique SCSI ID in order to
work properly. SCSI ID ranges from 0 up to 15, with 0
