Installing the Mylex Disk Array Controller as a Secondary
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 as a secondary controller. The following guidelines will
focus mainly on the important steps for installing the Mylex Disk Array
Controller 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.
Secondary Controller Installation Procedure
The procedure for installing the Mylex Disk Array Controller as a secondary
controller under SCO UNIX using Mylex drivers varies slightly depending
on the type of device that is installed as the primary controller:
• If the primary controller is IDE or EIDE, start at Step 1.
• If the primary controller is SCSI, start at Step 6.
1. Make sure the following SCO SCSI modules are enabled before
attempting to install the Mylex controller SCO mdac drivers into an
existing SCO system.
Sdsk : SCSI disk
Stp : SCSI tape
Srom : SCSI CD-ROM
2. Change to the sdevice.d subdirectory
# cd /etc/conf/sdevice.d
3. Enable the SCO UNIX SCSI modules by editing the files: Sdsk, Stp,
and Srom. Change the second field on all three files from N to Y.
Example of Sdsk file before edit (where x could be any digit):
Sdsk N x x x x x x x x
After edit:
Sdsk Y x x x x x x x x
