In-band SCSI
What is it and what is it used for?
These days more and more external devices require
communication with the host computer for device monitoring and
administration. This is usually done through RS-232C ports.
An alternative means of communication is now available for SCSI-
to-SCSI RAID controllers—In-band SCSI. The traditional way for
SCSI controllers to communicate with the host computer has been
via software (such as the GUI RAID Manager) using an RS-232C
connection. With In-band SCSI, integrators have more flexibility.
They may use RS-232C or the existing SCSI cable instead.
How is it able to use the SCSI cable? In-band SCSI technology
translates the original commands into standard SCSI commands.
These SCSI commands are then sent to and received from the SCSI
raid controller. The GUI RAID Manager can administrate the
RAID controller just as it could before via RS-232C. (Note: It is
assumed that users of In-band SCSI possess the following: a third-
party SCSI adapter and a channel on their ASUS RAID controller
that can be designated as a host channel.) Both of these are
required for In-band SCSI communication between the host and
the RAID controller. )

How Do You Configure the GUI RAID Manager to
Use In-band SCSI?
RAID Controller Adjustments
Don't disconnect your RS-232C cable yet! It is required for another
10 minutes or so. Some adjustments must be made to the RAID
