Using Sco Unix V/386; Transparency Of Host Drives; General Tips For Installation - ICP RS Series User Manual

H. Using SCO UNIX V/386
After having explained in chapters B and C the installation of the ICP Controller as well as
that of the Host Drives, we would now like to give you a few hints regarding the installation
of the operating systems
For a successful installation, it is essential to read the SCO system manuals thoroughly.
The required ICP disks can be created from the ICP System CDROM.
H.1 Transparency of Host Drives
The structure of the Host Drives, which have been installed with ICPCON (in chapter C), is
not known to UNIX. I.e., the operating system does not recognize that a given Host Drive
consists of a number of hard disks forming a disk array. To UNIX this Host Drive simply ap-
pears as one single hard disk with the capacity of the disk array. This complete transpar-
ency represents the easiest way to operate disk arrays under UNIX; neither UNIX nor the
PCI computer need to be involved in the administration of these complex disk array con-
figurations.
H.2 General Tips for Installation
In the following description, we shall explain the installation of SCO UNIX V/386 3.2v4.x
and 3.2v5.x step by step in combination with the ICP Controller. Apart from the SCO UNIX
floppy disks and the SCO UNIX documentation, you also need the ICP floppy disks (they
can be created from the ICP System CDROM):
GDT SCO UNIX BTLD-Disks
for the installation. In the following discussion, when we speak of a boot drive we refer to the
drive which is first integrated upon system power up. For the ICP Controller this drive is the
first Host Drive in the list of ICP Host Drives, i. e., the Host Drive number 0 (see ICPCON
menu Configure Host-Drives). During the installation you will have to decide whether you want
the ICP Controller to make the boot drive available, or whether you want to operate the ICP
Controller as an additional controller in the computer system.
If the ICP Controller is the only hard disk controller in the computer system, it will auto-
matically make the boot drive available. If there are more hard disk controllers, the con-
troller which makes the first drive available (the drive containing the MS-DOS partition C:)
will be the boot controller.
In principle, SCO UNIX is always installed on the hard disk with Target ID 0 and LUN 0 on
host adapter 0, that is on Host Drive 0 of this controller. If SCO UNIX is installed from tape
(streamer) the streamer must have SCSI ID 2 and be connected with SCSI channel A of host
adapter 0. For an installation from CD-ROM, the CD-ROM device must have SCSI-ID 5 and
has to be connected with channel A of the ICP Controller.
When using 3.2v4.x or 3.2v5.x, you have the option to link the driver to the kernel before
starting the kernel (btld (ADM)). This will allow you to use the ICP Controller as the only
controller in the system. Use the ICP BTLD Disk. During the installation, whenever the N1
floppy disk is inserted and the message
