■ Make the VCS configuration file read-only

# haconf -dump -makero

dependent modules

■ On each node, run the following command to stop VCS:

/sbin/init.d/vcs stop

■ After VCS takes all services offline, run the following command to stop

VxFEN:

/sbin/init.d/vxfen stop

■ On each node, run the following commands to restart VxFEN and VCS:

# /sbin/init.d/vxfen start

# /sbin/init.d/vcs start
