The Driver Parameters Tab
The Driver Parameters tab enables you to view and edit the HBA driver settings contained in a specific
host. The host driver parameters are global values and apply to all HBAs in that host unless they are
overridden by parameters assigned to a specific HBA using the HBA Driver Parameters tab. For each
parameter, the tab shows the current value, the range of acceptable values, the default value, and
whether the parameter is dynamic (a dynamic parameter allows the change to take effect without
resetting the HBA or rebooting the system).
For information on changing parameters for a single HBA, see “Setting Driver Parameters” on page 42.
For information changing parameters for the host, see “Setting Driver Parameters for a Host” on
page 44.

Driver Parameters Field Definitions
• Installed Driver Type - The current driver and version installed.
• Adapter Parameter table - A list of HBA driver parameters and their current values.
Modify Adapter Parameter Area
• HBA-specific information displays in this area. This can include Value, range, default, activation
requirements and description.
Driver Parameter Tab Buttons
• Restore - Click to save and restore parameters to this last saved value, if you have made
changes to parameters and have not saved them by clicking Apply.
• Defaults - Click to reset all parameter values to their default (out-of-box) values.
• Apply - Click to apply any driver parameter changes. If you changed a parameter that is not
dynamic, you must unload the driver and reload it.
Note: For the Linux 2.6 kernel, most driver parameters are set globally. You can set the
lpfc_log_verbose, lpfc_nodev_tmo and lpfc_use_adisc locally.
Note: If there is more than one driver type installed, the Installed Driver Types menu shows
a list of all driver types and driver versions that are installed on the HBAs in the host.
