Change the HEARTBEAT_IP for Cluster
I would like to modify the cluster setting from
NODE_NAME hpcluster
NETWORK_INTERFACE lan1
STATIONARY_IP 10.1.1.11
NETWORK_INTERFACE lan2
HEARTBEAT_IP 10.1.2.11
to
NODE_NAME hpcluster
NETWORK_INTERFACE lan1
HEARTBEAT_IP 10.1.1.11
NETWORK_INTERFACE lan2
HEARTBEAT_IP 10.1.2.11
I have modifed the file cmcluster.ascii, but is it necessary to halt the cluster before running "cmapplyconf -C cmcluster.ascii" ?
Also, is there anything should be done for the packages under this cluster? Actually, I do not want any changes for the packages.
Please help, thanks!
PS: OS is HP 11.23
My steps for modifying cluster:
#cd /etc/cmcluster
#cmgetconf -C backup.ascii
(modify cmcluster.ascii)
#cmcheckconf -C cmcluster.ascii
(halt the cluster if necessary)
#cmapplyconf -C cmcluster.ascii
(Any action should be taken on packages?)
