Q-Logic 8100 SERIES manual Making Persistent Changes Using modprobe

8–Configuring FCoE in a Linux Environment Configuring Driver Parameters Using modprobe

2.Load the QLogic FCoE driver module, and specify one or more parameters separated by a space. The following example enables MSI-X and Extended Error Logging:

#modprobe –v qla2xxx ql2xenablemsix =1 ql2xextended_error_logging=1

3.Verify the parameter changes by issuing the following commands:

#cat /etc/bus/pci/drivers/qla2xxx/module/parameters/ql2xenablemsix

#cat /etc/bus/pci/drivers/qla2xxx/module/parameters /ql2xextended_error_logging

Making Persistent Changes Using modprobe

Persistent changes are preserved across server reboots. To make persistent changes to adapter driver parameters:

1.Open the file /etc/modprobe.conf in read/write mode using a Linux editor by issuing the following command:

#vi /etc/modprobe.conf

2.Add the options line for the appropriate driver parameter by issuing the following command:

options qla2xxx ql2xenablemsix=1 ql2xextended_error_logging=1

Figure 8-1shows the result.
