Hi Gouranga ,

You can stop the package , then stop the node , the stop the cluster.

# cmhaltpkg -n pri_node -v pkg_name
# cmhaltnode -v nodename
# cmhaltcl

---------
To restart:
# cmruncl
# cmrunpkg -n pri_node -v pkg_name

--
If a package halt fails, the cluster halt will also fail. So shutding down the pacakge with cmhaltpkg will help you to go step by step. For details startup/stop messages you can refer to /etc/cmcluster/pkg_name/pkg_name.cntl.log file.

After restart check with :
# cmviewcl or # cmviewcl -v

Cheers,
Raj.

Hi,

I have indicated with following assumption,

Assumption:

cluster name : clust1
node1 name : nodea
node2 name : nodeb
pkg1 name : pkga (pri nodea, alt nodeb)
pkg2 name : pkgb (pri nodeb, alt nodea)

Steps:
1)Stopping cluster

Login to nodea
stop all the packages
#cmhaltpkg -v pkga
#cmhaltpkg -v pkgb

stop all the nodes
#cmhaltnode -v nodea
#cmhaltnode -v nodeb

stop the cluster
#cmhaltcl

Verify
#cmviewcl -v

2)starting cluster
start cluster
#cmruncl

start the nodes
#cmrunnode -v nodea
#cmrunnode -v nodeb

start the packages
#cmrunpkg -v -n nodea pkga
#cmrunpkg -v -n nodeb pkgb

enable package for package switching
#cmmodpkg -e pkga
#cmmodpkg -e pkgb

verify
#cmviewcl -v

NOTE: make sure all the while you do not encounter errors. You will usually fing the errors in 3 places. One on the terminal you run the command, second, in /var/adm/syslog/syslog.log file and lastly in /etc/cmcluster//
