Cluster IP

[Roberto Severo]

Hi,

I'm a newbie on Service Guard, and I have a cluster with 2 machines. What is the easiest way to discover the ip address of the cluster (in which machine is running) only referencing its hostname.

Thanks a lot

Log into any of the nodes and do a cmviewcl to see what packages are configured and running on which node.

This should provide the info you need.

Hi Roberto,

I'm not certain what you mean by "cluster IP". There is no such thing as a "cluster IP".

Perhaps you are referring to a "relocatable IP" that is assigned to a LAN adapter when a ServiceGuard package starts on a particular node. When that package is halted, the Reloc. IP is removed from the NIC, and when the package is started on another node, the relocatable IP moves to that other node.

Such a relocatable IP can be given an alias name in /etc/hosts or your DNS server, so that users don't have to remember an IP in order to get to the package, on whichever node it is running.

-S.D.

Yes, I've re-posted the message. I think this is the right place to ask about a Service Guard command. Not there.

Thank Notifying me.

There is no such thing Cluster IP.
You have packages in cluster that have IP.

cmviewctl to see what packages you have there, then go to one of the machines to:
/etc/cmcluster/
and see in .cntl file the properties of this package, IP will be there too.

sorry, it's *cmviewcl*, not *cmviewctl*

my mistake.

cmviewcl

then

cmgetconf -c clustername cluster.ascii

Where clustername is the name of the cluster from the cmviewcl command...

vi the cluster.ascii file and you will see your ip addresses...
