Parameter Options

You can set the eri device driver parameters in three ways (ndd, /etc/system, and eri.conf), depending on your needs. To set parameters that are valid until you reboot the system, use the ndd utility. Using ndd is a good way to test parameter settings.

To set parameters so they remain in effect after you reboot the system:

• Add the parameter values to /etc/system when you want to configure parameters for all devices in the system.

• Create the eri.conf file and add parameter values to eri.conf when you need to set a particular parameter for a device in the system.

If you want to test parameter settings, use the ndd utility described in "Setting Parameters Using ndd". With ndd, the parameters are effective until you reboot the system. To make the parameter settings permanent, enter the values in /etc/system or eri.conf as described in this chapter.
