Installing the Mylex Disk Array Controller as the Primary
Controller
This section provides guidelines for the system administrator to follow
during the installation of SCO UNIX to prepare it for using the Mylex Disk
Array Controller (DAC) as the primary controller. The following guidelines
will focus mainly on the important steps for installing the SCO UNIX
drivers. For detailed information about the operating system installation,
consult the SCO UNIX documentation.
If a tape drive connected to the controller is being used for installation, make
sure that the tape drive is set to SCSI ID 2, that the configuration utility has
been run with the tape drive installed, and that the configuration has been
saved. The same is also true when using a CD-ROM, except the CD-ROM
needs to be set to SCSI ID 5.
Prepare the system to receive the SCO OpenServer 5.0.4 driver by
performing the following procedure:
1. Insert the OpenServer Boot Disk into the primary floppy and boot the
system. The following prompt will be displayed:
Boot
:
2. Type ahslink at the colon(:) and press Enter.
: ahslink
↵
☛
Note
When running SCO 5.0.4 on a system with an
additional SCSI controller, to install the controller at
the boot prompt, enter:
Boot: defbootstr ahslink=mdac Sdsk=mdac(0,0,0,1)
☛
Note
If installing onto a system that is SISL capable and
using a SISL capable DAC it is recommended to
disable the SCSI chip driver on the system by entering
the following at the boot prompt:
Boot: defbootstr ahslink=mdac Sdsk=mdac(0,0,0,1)
disable=[scsi chip driver name]
