How to discover which VCS clusters reside on a subnet ?

[Barak Ron]

Hi,

In our testing lab, we have several VCS (Veritas) clusters, all on the same subnet.
To distinguish among the various VCSs, one sets a unique number for the 'set-cluster' parameter of /etc/llttab.

My question:
Is there a way to send a (broadcast) message on the subnet and have all nodes/clusters answer with their set-cluster parameters, so that if a new cluster is created, its set-cluster parameter will not conflict with existing clusters ?

For example, the /etc/llttab of one cluster has no set-cluster, another has 'set-cluster 2' and a third has 'set-cluster 7'. One installs a new cluster, and would like to know that 1,2, and 7 are already taken.

Any help is appreciated.

Thanks and bye,
Ron.

Shalom Ron,

Not really, unless Veritas provides this facility.

Best you can do is at start up have the cluster write to a file on NFS or some common area what its information is. When setting up new clusters, you will need to require your administrators to check this configuration file.
