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 HP Ultra3 SCSI host bus 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. Removing the Driver If you no longer need the adst21 or adst70 driver, you can use the following procedure to remove it completely: 88
