Configuring FCoE Parameters Using QLogic Utilities
FE0254601-00 A 8-9
To modify FCoE driver parameters using sysfs:
1. Change to the sysfs location where the driver parameter resides by issuing
the following command:
#cd /sys/module/qla2xxx/parameters
2. Modify the sysfs entry for the corresponding driver parameter. The
following example sets the maximum queue depth to 64:
#echo 64 > ql2xmaxqdepth
3. Verify the changes. The following example should report 64, if the previous
command was successful.
#cat /sys/module/qla2xxx/parameters/ ql2xmaxqdepth
