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
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
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
