Configuring the wdha driver

You can configure the wdha driver using entries in /etc/conf/cf.d/mdevice and /etc/conf/sdevice.d/wdha. See mdevice(F) and sdevice(F). Changes to these files will only take effect if the kernel is relinked using link_unix(ADM) and the machine rebooted.

Configure wdha driver-specific characteristics by editing the /etc/conf/pack.d/wdha/space.c file.
