Table 3-5
VXFEN tunable parameters (continued)
Description and Values: Default, Minimum, and Maximumvxfen Parameter
Specifies the maximum number of seconds that the smaller
sub-cluster waits before racing with larger sub-clusters for
control of the coordinator disks when a split-brain occurs.
This value must be greater than the vxfen_max_delay value.
■ Values
Default: 60
Minimum: 1
Maximum: 600
vxfen_max_delay
Specifies the minimum number of seconds that the smaller
sub-cluster waits before racing with larger sub-clusters for
control of the coordinator disks when a split-brain occurs.
This value must be smaller than the vxfen_max_delay value.
■ Values
Default: 1
Minimum: 1
Maximum: 600
vxfen_min_delay
Specifies the time in seconds that the I/O fencing driver VxFEN
waits for the I/O fencing daemon VXFEND to return after
completing a given task.
■ Values
Default: 60
Minimum: 10
Maximum: 600
vxfen_vxfnd_tmt
In the event of a network partition, the smaller sub-cluster delays before racing
for the coordinator disks. The time delay 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.
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.
