Configuration Parameters
2.3.1
Linux Enhanced Driver Parameters
2.3.1.1
Basic Parameters
QLogic configuration parameters are stored in the modules.conf file in the
subdirectory /etc. Values of parameters in the file are found in the readme.txt file
associated with the enhanced driver.
2.3.1.2
Configuration Parameter
To maintain backward compatibility, if the configuration cannot be read from
persistent storage, the enhanced driver defaults to the previous operation of
configuring and enabling all devices that are found. Some OEMs indicate that this
is an unacceptable risk when adding a new host to a SAN system and that the
desired operation is to configure no devices instead of all devices. The parameter
value is ConfigRequired=1 (TRUE) in Linux.
2.3.2
NetWare Enhanced Driver Configuration Parameters
QLogic configuration parameters are stored in the QL2x00.cfg file in the default
DOS directory, C:\Nwserver. Values of parameters in the file are created and saved
by the NetWare agent and not intended for modification or editing.
