That is an extremely broad question. It would help if you gave some guidelines to the context of your question. There are several commands in HPUX that will give you some kind of node information, netstat just to name one.

Are you talking about in a Serviceguard cluster for Failover? Are you talking about in one network? All the nodes in a certain token ring, FDDI ring? Are you talking about nodes that are active with the current system? Are you talking about what nodes are within an entire company?

My company has over 2000 systems in the southwest region of the US for 5 states! And we have 8 other states with systems there as well!

NAME

       cm - cluster monitor for high availability clusters

   Remarks
       Cluster	operations require the installation of the optional Serviceguard or Serviceguard Extension for RAC software, which is not included
       in the standard HP-UX operating system.

DESCRIPTION

       Serviceguard and Serviceguard Extension for RAC are high availability products which provide an environment such that after a failure of  a
       node,  services	(applications)	can be up and running again on another node within a very short amount of time.  In addition, Serviceguard
       Extension for RAC is the enabling software for the Real Application Clusters (RAC).  Working with the basic Serviceguard product,  Service-
       guard Extension for Faster Failover allows configuration of clusters for optimized failover.

   Commands
       The following set of commands is used to configure a high availability cluster:

		     cmquerycl(1M)
		     cmmakepkg(1M)
		     cmcheckconf(1M)
		     cmapplyconf(1M)

       The following commands are used to run or halt a cluster:

		     cmruncl(1M)
		     cmhaltcl(1M)
		     cmrunnode(1M)
		     cmhaltnode(1M)
		     cmviewcl(1M)

       Once a cluster is formed, the following commands are provided for manual operation on high availability packages:

		     cmrunpkg(1M)
		     cmhaltpkg(1M)
		     cmmodpkg(1M)

       The following commands are used within a package control script to control the services and networks configured for a package:

		     cmrunserv(1M)
		     cmhaltserv(1M)
		     cmmodnet(1M)

       A command is provided to aid in migrating from a SwitchOver/UX configuration to a Serviceguard cluster:

		     cmmigrate(1M)

       This command is not applicable with Serviceguard Extension for RAC.
