How to change IP address of heartbeat monitoring (MC-Service Guard Setup).

[Kripal_1]

Hi,

My requirement is to change the IP address of my heartbeat monitoring (MC-Service Guard Setup).

Environment details are :- HP-UX B.10.20 A 9000/785 2007863207

I want to know where (which files ) the changes have to be done for changing IP address which MC-Service Guard" will use to
monitor and control the mentioned IP addresses.

Is there any documented procedure available for this activity ?

Please anyone could provide these details.

Regards
Kripal

The IP address of the nodes is set in the cluster configuration file /etc/cmcluster/cluster.conf . In this file you store the IP of the nodes . Once you have modified this file you must apply the binaries "cmapplyconf....."
The IPs of the packages are configured in the control file of each package "/etc/cmcluster/pkgxxxxx/pkgxxxx.cntl"

In the web docs.hp.com , in the "Managing Service Guard" guide you will find the procedures to do so

First of all,

1.Stop the cluster that you are running for reconfiguring from old to new IP address.

# cmhaltcl -f

2.change proper the IP address for heartbeat in /etc/cmcluster/cluster.ascii ( cluster configuration file)

# vi /etc/cmcluster/cluster.ascii

--------------------------------------------
NETWORK_INTERFACE lan1
HEARTBEAT_IP xxx.xxx.xxx.xxx <- new

FIRST_CLUSTER_LOCK_PV /dev/dsk/c7t0d4

--------------------------------------------


3. Check the changed configuration file in the cluster.


# cmcheckconf -C /etc/cmcluster/cluster.ascii

4. copy and apply for making binary file for taking effect

# cmapplyconf -C /etc/cmcluster/cluster.ascii


5. run the cluster and monitor the control logs.

# cmruncl

# tail -f /etc/cmcluster/pkg/pkg.*cntl





Best Regards.

Actual procedure is in this doc under "reconfiguring a cluster".
