Configuring the VXFEN module parameters


Configuring the VXFEN module parameters
Prev	About VXFEN tunable parameters	Next

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

Stop all the applications that are not configured under VCS. Use native application commands to stop the application.
Stop VCS on all the nodes. Run the following command on each node:
```
# hastop -local
```
Stop the VxFEN driver.
```
# /etc/init.d/vxfen stop
```
Edit the /etc/sysconfig/vxfen file.
For example, change the entry from:
```
vxfen_min_delay=1
```
to:
```
vxfen_min_delay=30
```
Start the VXFEN module.
```
# /etc/init.d/vxfen start
```
Start all the applications that are not configured under VCS. Use native application commands to start the applications.
