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.
