Step 7: Install the IP Communications Driver
As an option, you can install the IP communications driver. To use the NDIS driver
to enable IP traffic over FC, install that device driver and its configuration utility.
Non-Windows Configuration Parameters
This section lists specific configuration parameters for Linux, Macintosh, and
NetWare.
Linux Enhanced Driver Parameters
QLogic configuration parameters are stored in the modules.conf file in the
/etc subdirectory. For parameter values, see the readme.txt file for the
enhanced driver.
To maintain backward compatibility, if it cannot read the configuration from
persistent storage, the enhanced driver defaults to the previous operation of
configuring and enabling all devices found. Some OEMs indicate that this is an
unacceptable risk when adding a new host to a SAN system; they would rather
configure no devices instead of all devices. The parameter value is
ConfigRequired=1 (TRUE) in Linux.
Macintosh Basic Parameters
QLogic configuration parameters are stored in two files:
/etc/QLogicHBA23xx.conf
/System/Library/Extensions/QLogicHBA23xxConfig.kext/Contents/
QLogicHBA23xxConfig
This is a config module binary.
The qla_opts utility in the source code of Failover API can read the config file
and write to the config module.
NetWare Enhanced Driver Configuration Parameters
NetWare stores QLogic configuration parameters in the QL2x00.cfg file in the
default DOS directory, C:\Nwserver. The NetWare agent creates and saves
parameter values in the file; this file is not intended for modification nor editing.
NOTE:
If you are using the IOCTL module with the inbox driver or if you are using
sysfs/IOCTL module based drivers in Red Hat 4.0, persistent configuration
is not saved. Additionally, persistent configuration is not saved if you are
using inbox drivers with SLES 10.0.
