The HBAnyware Utility User Manual Page 77
Driver for Linux, LPFC and LPFCDFC Parameter Tables
The driver parameter values listed in Table 3 are applicable to driver version 8.0.16.34 or later. If you
are using a version previous to 8.0.16.34, see the Emulex Driver for Linux User Manual for parameter
information
The parameters determine some aspects of the driver behavior. The following tables list the driver
parameters. Some driver parameters can be modified and take effect only on a driver load while others
can be modified dynamically and take effect immediately. The tables also list the default, minimum and
maximum values for these parameters.
In Table6, driver parameters marked with an asterisk are not supported by HBAnyware. You can change
them via LPFC. See the Driver User Manual for more Information.
