Configuration Methods
There are four ways to configure the driver:
● Permanently (global)
● Permanently (per adapter)
● Temporary (global)
● Temporary (per adapter)
Permanent Configuration Methods
Permanent configuration requires that the new values be saved and the driver rebuilt.
These changes are considered permanent because they stay in effect until a driver
parameter is changed, saved and rebuilt again.
All parameters are contained in /etc/lpfc.conf which is symbolically linked to lpfc.conf in the
driver installation directory.
To make changes that impact all host bus adapters in the system (global changes),
edit the lpfc.conf file. Parameter values are hexadecimal.
1. Go to the driver source directory.
2. Edit lpfc.conf to change the desired parameter.
3. Save the changes.
4. Rebuild the driver or build a new kernel with the driver (if applicable).
