Hi,

The cluster configuration file is better known as the ASCII file. It will be generated by running the 'cmquerycl' command when you are building your cluster orginally.

This file will usually reside in:
/etc/cmcluster

However, once you have a running cluster you can delete the ASCII file. To regenerate the ASCII cluster file (basically you will load all the configuration settings from the running cluster) use the 'cmgetconf' command, e.g.:
# cmgetconf -c /tmp/cmcluster.ascii

Packages will all have their own configuration files (modular packages will only have a configuration file, legacy packages will have both a configuration and control file). These configuration files can usually be found in:
/etc/cmcluster/

Or you can use the 'cmgetconf' command again to generate the configuration files:
# cmgetconf -c -P /tmp/package.conf

Hope that help! If you have any specific questions do let me know...

Please read the "Managing Serviceguard" book.

It contains very detailed descriptions of each configuration file. It contains *everything* a HP-UX administrator needs to know about Serviceguard clusters.

The book comes with each Serviceguard license as an actual physical book, and is also available in PDF format at:

if you regenerate the ascii file using the cmgetconf the file has hundreds of lines of comments that document each of the parameters in the file.

THe highlights are
Name of the cluster
quorum mechanism
section for each node that describes the nic cards of each node and how each node accesses a lock disk if used and what nic card is the heartbeat lan

and the rest of the file has cluster parameters like timeouts.
