Configuring Multiple SCSI Controllers
The following procedure uses AHA-
2940/W/UW SCSI controller as an example.
Follow these steps to configure multiple SCSI controllers:
1.
Install the boot SCSI controller in the lowest PCI Device number.
The Device number is determined by the slot number on the PCI
bus.
a.
To find out the Device number of the AHA-2940 SCSI
controller(s), run the SCSISelect utility by pressing the key
combination
b.
On the first screen of SCSISelect, look for the following on
the upper right hand corner.
Bus:Device xx:xxxh
c.
If the device number is high, move the AHA-2940 to a PCI
slot at the other end of the system board then rerun
SCSISelect to see if the number is lower.
Step 1.3 is a recommended solution for most
PCI systems. You can move the AHA-2940
SCSI controller to another PCI slot if the boot
order is not what is desired.
d.
Refer to your system documentation for further details on
determining the PCI slot number and slot number order in
the system.
2.
If you are booting from the AHA-2940 and using ISA/EISA-based
host adapters as secondary devices, you must disable the BIOS
on all ISA/EISA-based SCSI controllers.
