System Overview

Step 6: Configure the Disks in the Operating System
After completing all hardware and configuration for FC subsystems, use the appropriate operating system utilities to enable devices, assign drive letters or logical names, and initialize file systems for each device or LUN on the system.
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
NOTE:
If you are using the IOCTL module with the inbox driver or if you are using sysfs/IOCTL
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.
