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.
