ULTRA2 LVD SCSI HOST ADAPTER
3B. If the Ultra2 LVD SCSI Host Adapter is NOT intended to be the bootable host adapter,
these instructions will guide you through changing the current software
settings for UnixWare to establish the
Ultra2 LVD SCSI Host Adapter
as a non-
bootable host adapter for your device. At the system command prompt, type
/etc/conf/bin/idbuild -Ma100 <ENTER>
cd / <ENTER>
shutdown -g0 <ENTER> (the “0” in “-g0” is a zero)
Y <ENTER>
4 Exit the UnixWare program and reboot your system to initialize the new
device driver to control the Adapter.

UnixWare is capable of supporting up to eight SCSI buses. If you choose to use
multiple host adapters in your system—even if they are different models or
makes—verify that each host adapter’s shared interrupt level is set to IRQ10. Please
refer to your system documentation to set the interrupt levels.
You should configure and allocate space for each host adapter in the system by
making sure there is a separate line for each adapter in the “/etc/conf/sdevice.d/
a100” file. Make sure that “Y” is selected in the second field of each of these lines
that correspond to one of our
Ultra2 LVD SCSI Host Adapters
, so that their I/O
can be handled by the a100 driver that was designed for them. UnixWare will
automatically rebuild the kernel when an additional Adapter is detected.
