UnixWare Installation
Using UnixWare and the Host Adapter
This section contains useful information on using UnixWare and
your host adapter.
Using Tunable Parameters
For UnixWare, some parameters are defined in the following files:
/etc/conf/pack.d/adst21/space.c
or
/etc/conf/pack.d/adst70/space.c
These parameters can be tuned for either the
adst21
driver or the
adst70
driver.
Please refer to the comments in the appropriate
space.c
file for a description of these parameters. After modifying
the
space.c
file, you must rebuild the kernel then reboot the system
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 Ultra160 Family host adapter, make sure the
host adapter is installed in the lowest PCI slot number. See
your host adapter’s user’s guide.
■
UnixWare 2.1x and UnixWare 7.01/7.1 supports auto-
configuration. When adding multiple host adapters to an
existing UnixWare 2.1x and 7.01/7.1 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.
