About VXFEN Tunable Parameters
On each node, edit the file /kernel/drv/vxfen.conf to change the value of the vxfen driver tunable global parameter, vxfen_max_delay and vxfen_min_delay. You must restart the system to put change into effect.

vxfen_max_delay
|
Specifies the maximum number of seconds that the smaller sub-cluster waits before racing with larger clusters for control of the coordinator disks.
This value must be greater than the vxfen_max_delay value.

Values
Default: 60
Minimum: 0
Maximum: 600

vxfen_min_delay
|
Specifies the minimum number of seconds that the smaller sub-cluster waits before racing with larger clusters for control of the coordinator disks. This value must be smaller than the vxfen_max_delay value.

In the event of a network partition, the smaller cluster delays before racing for the coordinator disks. The time delayed allows a larger sub-cluster to win the race for the coordinator disks. The vxfen_max_delay and vxfen_min_delay parameters define the delay in seconds.
