C-4Drive Configuration Options

Configuring the SCSI ID in a

SCO OpenServer environment

In the pre-configured kernel used to install SCO OpenServer, the following SCSI IDs are automatically set:

■Disk = 0

■Tape = 2

■CD-ROM = 5.

If required, the user may reconfigure the ID for the Compaq SLR Drive using the mkdev tape command. To verify the ID, use the hwconfig command look for the same %tape string or check the %tape string as it appears on the console as the kernel starts up. The information will appear in a line such as this:

%tape - - - type= S ha=0 id=2 lun=0 ht= ...

In the above example, “id=2” indicates that the drive’s SCSI ID = 2.

IMPORTANT: SCO OpenServer’s install kernel will only communicate with the first SCSI controller in the system. Remove the generic tape at SCSI ID = 2 then install the appropriate tape driver. Set the required SCSI ID, bus, and lun values.

Enabling/Disabling Bus Parity

Installing the PARITY jumper enables bus parity checking.

IMPORTANT: Compaq ships the drive with this jumper installed.

Testing

The TEST and TEST CONN jumpers enable selftest and off-line testing capabilities which are beyond the scope of this guide.
