Using UnixWare/Open Unix and the Host
Adapter
This section contains useful information on using UnixWare/Open
Unix and your host adapter.
Using Tunable Parameters
For UnixWare/Open Unix, some parameters are defined in the
following file:
/etc/conf/pack.d/adpu320/space.c
These parameters can be tuned for either the
driver. Please refer to the comments in the appropriate
adpu320
file for a description of these parameters. After modifying
space.c
the file, you must rebuild the kernel then reboot the system
space.c
for the new parameters to take effect. To rebuild the kernel, type
the following, and press Enter after each line:
/etc/conf/bin/idbuild -B
cp /etc/conf/cf.d/unix /stand/unix
Note: The drivers support Tagged Queuing and
Reinitialization.
Using Multiple Host Adapters
When using multiple host adapters, consider the following:
The host adapter and computer must be configured for multiple
host adapters as explained in the host adapter's user's guide.
To boot from the Ultra320 host adapter, make sure the host
adapter is installed in the lowest PCI slot number. See your host
adapter's user's guide.
UnixWare/Open Unix supports auto-configuration. When
adding multiple host adapters to an existing UnixWare/Open
Unix system, simply install the board and reboot; the system
automatically reconfigures and rebuilds the kernel. If you want
to select a host adapter to boot from, simply disable the BIOS on
all other host adapters.
