8–Configuring FCoE in a Linux Environment Configuring FCoE Parameters Using QLogic Utilities

Table 8-2. FCoE Driver Parameters that can be Modified with Sysfs

Sysfs Location	Driver Parameters
/sys/module/qla2xxx/parameters	ql2xmaxqdepth
	ql2xplogiabsentdevice
	ql2xqfullrampup
	ql2xqfulltracking
/sys/class/scsi_host/hostX/	zio (operation mode)
	zio_timer (interrupt delay timer)

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
