Your new configuration will now be in effect. If necessary, run the
System Configuration program described in Chapter 3 to ensure
that your system setup matches your UNIX SCSI settings.
Configuring the SCSI Adapter
and Devices
This section describes guidelines for you to follow when
configuring your UNIX system with a SCSI adapter card.
I
Changing the SCSI Adapter Card Mode
When you install the UNIX system, the SCSI adapter card must be
in Standard mode. (The card is shipped in Standard mode.) If you
change to Enhanced mode when you install the UNIX SCSI
Manager, you must change your SCSI system configuration to
Enhanced mode also. (See Chapter 3 for details.)
You cannot access any devices that you configure as attached to
the eiad host adapter until you reconfigure the SCSI adapter card
to Enhanced mode.
Defining the Primary Host Adapter
If you boot from a SCSI hard disk drive, the SCSI adapter card to
which you attach the drive is the primary host adapter.
Using Multiple SCSI Adapters
If you install two SCSI adapter cards in your system, the card
installed in the slot with the lowest number is adapter 0. The card
installed in the slot with the higher number is adapter 1.
For example, if you install the first SCSI adapter card in slot 3 of
an EISA desktop computer, it becomes adapter 0. You can then
install the second SCSI adapter card in slot 4; it becomes adapter 1.
Be sure to use the correct numbers when you specify the adapters.
