Configuring the VXFEN module parameters

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.

Note:

You must restart the VXFEN module to put any parameter change into effect.

To configure the VxFEN parameters and reconfigure the VxFEN module

  1. Unconfigure the VXFEN module.

    # vxfenconfig -U
  2. Unload the module.

    # /etc/init.d/vxfen stop
  3. Edit the /etc/sysconfig/vxfen file.

    For example, change the entry from:

    vxfen_min_delay=0

    to:

    vxfen_min_delay=30
  4. Start the VXFEN module.

    # /etc/init.d/vxfen start
