After adjusting the tunable kernel driver parameters, you must reconfigure the VXFEN module for the parameter changes to take effect.
The following example procedure changes the value of the vxfen_min_delay parameter.
On each Linux node, edit the file /etc/sysconfig/vxfen to change the value of the vxfen driver tunable global parameters, vxfen_max_delay and vxfen_min_delay.
To configure the VxFEN parameters and reconfigure the VxFEN module
# hastop -local
For RHEL 7, SLES 12, and supported RHEL distributions:
# systemctl stop vxfen
For earlier versions of RHEL, SLES, and supported RHEL distributions:
# /etc/init.d/vxfen stop
For example, change the entry from:
vxfen_min_delay=1
to:
vxfen_min_delay=30
For RHEL 7, SLES 12, and supported RHEL distributions:
# systemctl start vxfen
For earlier versions of RHEL, SLES, and supported RHEL distributions:
# /etc/init.d/vxfen start
# hastart
