Disabling I/O fencing

You may have to disable fencing in the following cases:

By default, the VxFEN driver operates with I/O fencing enabled. To disable this feature without removing the coordinator disks, you must create the file /etc/vxfenmode and include a string within the file to notify the VxFEN driver.

 To stop and restart the driver

  1. To stop and restart the driver, type the following commands:

    # echo "vxfen_mode=disabled" > /etc/vxfenmode

    # /etc/init.d/vxfen stop

    # /etc/init.d/vxfen start

  2. Additionally, Veritas recommends removing the /etc/vxfendg file if fencing is to be later reenabled.
