cmhaltcl - halt a high availability cluster
cmhaltcl [-f] [-v]
cmhaltcl causes all nodes in a configured cluster to stop their cluster daemons, optionally halting all packages or applications in the
To stop a cluster, a user must either be superuser(UID=0), or have an access policy of FULL_ADMIN allowed in the cluster configuration
file. See access policy in cmquerycl(1).
This command will halt all the daemons on all currently running systems. If the user only wants to shutdown a subset of daemons, the
cmhaltnode command should be used instead.
cmhaltcl supports the following options:
-f Force the cluster to shutdown even if packages or group members are currently running. This will cause the packages and group
members to be halted. If a package halt fails, the cluster halt will also fail.
-v Verbose output will be displayed.
cmhaltcl returns the following value:
0 Successful completion.
1 Command failed.
Halt the cluster daemons:
cmhaltcl was developed by HP.

cm - cluster monitor for high availability clusters
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.
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.
The following set of commands is used to configure a high availability cluster:
The following commands are used to run or halt a cluster:
Once a cluster is formed, the following commands are provided for manual operation on high availability packages:
The following commands are used within a package control script to control the services and networks configured for a package:
A command is provided to aid in migrating from a SwitchOver/UX configuration to a Serviceguard cluster:
This command is not applicable with Serviceguard Extension for RAC.
