About SCSI
See Mixing SE Devices with LVD Devices on page F-3 for more
details.
Setting SCSI IDs
For each controller channel, the SCSI IDs of the devices must be
unique numbers between 0 and 15. The controller, itself a SCSI
device, is usually set to ID 7 by default. SE drives usually support
IDs between 0 and 6.
SCSI enclosures that use SCSI drives with 80-pin SCA connectors
typically assign the drive ID automatically when the drive is
inserted. You don’t need to set device IDs with such enclosures
unless your enclosure requires it. For details, refer to the enclosure
User’s Guide.
The RAID controller ID can be changed to any ID from 0 through 7
using the ARC utility.
Note: Do not change the controller ID unless the change is
absolutely necessary.
Changing SCSI Termination on the Controller
The default termination for the controller is Auto Mode and you will
probably never need to change this setting. However, if you do
need to change the termination, you can use the SCSISelect
Controller SCSI Channel Termination option to change the setting
to Disabled. For details, see
page A-12 .
All these SCSI controllers support multimode SCSI termination.
Enabling CD Drive Support
Note: Adaptec SCSI RAID controllers do not support CD
drives in Linux systems.
If you attached a CD drive to the controller, you need to configure
the controller BIOS as follows to make the CD drive work:
1 While the system is starting, press Ctrl-A when the controller
displays its message on the screen.
