Configure stand by LAN for node on running Cluster : How to ??

consider cluster is having 2 nodes - nodeA and nodeB. and i added stand by lan for nodeB.


>>Login to the server nodeA

STEP 1 : remove the node from all package configuration
#cmviewcl -v

#cmgetconf -v -p pkgname pkngname.conf_new


Then remove the below line from the conf file

#vi pkgname.conf_new

NODE_NAME                 nodeB

save and exit

# cmcheckconf -v -P pkngname.conf_new

# cmapplyconf -v -P pkngname.conf_new



#cmviewcl -v -p pkngname.conf_new  -----> verify the node is removed from pkg config

=================================================


STEP 2: Halt the node nodeB and remove the node from cluster


#cmviewcl -v

#cmhaltnode -v nodeB

#cmgetconf -v -c clustername cluster.ascii

Edit the cluster.ascii file and remove the node - nodeB  from that file


#NODE_NAME                      nodeB
  NETWORK_INTERFACE     lan0
   HEARTBEAT_IP                 10.161.1.58
  NETWORK_INTERFACE     lan2
   HEARTBEAT_IP                 10.160.7.72



save and exit

#cmcheckconf -v -C cluster.ascii

#cmapplyconf -v -C cluster.ascii

#cmviewcl -v


==================================================================================================

STPE 3 : Add the node nodeB  to cluster with standby lan.

#cmgetconf -v -c cluster cluster.ascii

#edit the cluster.ascii and then add node nodeB with standby lan

NODE_NAME                       nodeB
NETWORK_INTERFACE     lan0
HEARTBEAT_IP                 10.161.1.58
NETWORK_INTERFACE     lan2
HEARTBEAT_IP                  10.160.7.72
NETWORK_INTERFACE     lan3

save and exit.


#cmcheckconf -v -C cluster.ascii

#cmapplyconf -v -C cluster.ascii

Then start the cluster on nodeB

#cmrunnode -v nodeB

#cmviewcl -v

==================================================================================================

STPE 4 : Need to add the node to all the package  where this node already configured.


#cmgetconf -v -p pkgname  pkgname.conf_new

Then add the below line from the conf file

#vi pkgname.conf_new

NODE_NAME                 nodeb

# cmcheckconf -v -P pkgname.conf_new

# cmapplyconf -v -P pkgname.conf

#cmviewcl -v -p pkgname -----> verify the node is removed from pkg config
