Shalom,

No its not necessary to bring down the cluster.

Make the change on one node.

copy the package configuration script to the second

cmcheckconf
cmapplyconf

>> Simply edit the cluster ascii file
The cluster configuration file is in /etc/cmcluster on one of the nodes.

If the file cannot be located, recreate it with this command:

# cmgetconf cluster.ascii

Edit the cluster configuration file, make the changes
FAILBACK_POLICY=MANUAL and AUTO_RUN=YES

After the changes been done
# cmcheckconf -C
# cmapplyconf -f -C

>> Copy the ascii file to the other node also!

>> Simply edit the package configuration file
The package configuration file is in /etc/cmcluster///.conf

Edit the package configuration file, make the changes
FAILBACK_POLICY=MANUAL and AUTO_RUN=YES

>> Copy the ascii file to the other Cluster nodes.

Update the cluster binary file

# cmcheckconf -P <.conf>
# cmapplyconf -f -P <.conf>

>> Please verify if
AUTO_RUN is enabled for that particular pacakge via
# cmviewcl

>> If not, enable switching via
# cmmodpkg -e
