
Adapter-specific information is displayed in this area. This can include value,
range, default, activation requirements and description.
Driver Parameters Tab Buttons (Not available in read-only mode.)

Restore – If you changed driver parameters, but did not click Apply and you
want to restore the parameters to their last saved values, click Restore.

Defaults – Click to reset all driver parameter values to their default (out-of-box)
values.

Apply – Click to apply any driver parameter changes. If you changed a driver
parameter that is not dynamic, you may need to reset the adapter port or create
a new ramdisk and reboot the system.
Setting Driver Parameters
The Driver Parameters tab for adapters and hosts enable you to modify driver
parameters for a specific adapter or all adapters in a host.
For example, if you select a host in the discovery-tree, you can globally change the
parameters for all adapters in that host. If you select an adapter port in the
discovery-tree, you can change the lpfc_use_adisc, lpfc_log_verbose and the
lpfc_nodev_tmo parameters for only that adapter.
Note: VMware supports local and global parameter changes for all driver parameters.
For each parameter, the Driver Parameters tabs show the current value, the range of
acceptable values, the default value, and the activation requirement. You can also
restore parameters to their default settings.
You can apply driver parameters for one adapter to other adapters in the system using
the Driver Parameters tab, thereby simplifying multiple adapter configuration. See
“Creating a Batch Mode Driver Parameters File” on page 155 for more information.
Note: The Linux 2.6 kernel only supports setting some of the driver parameters for
individual adapters. Some driver parameters must be applied to all adapters
contained in the host. See the Emulex Driver for Linux User Manual for more
information.
Setting Driver Parameters for a Single FC/FCoE Port
To change the driver parameters for a single FC/FCoE port:
1. Select Host or Fabric view.
2. In the discovery-tree, select the FC or FCoE adapter port whose parameters you
want to change.
3. Select the Driver Parameters tab. The parameter values for the selected adapter are
displayed.
