Use the start-up script in $SYBASE/$SYBASE_ASE/install to restart the primary companion without monitoring it:
startserver -f ./RUN_<server_name>
If you use this script to start a companion server, it does not fail over when the server goes down, even if it is configured to do so. Use this method only if you are performing maintenance and you do not want the server databases to be accessible while the server is down.
