groups, filesystems, logical volumes, and mount options in the package control script.

You can use DSAU to centralize and simplify configuration and monitoring tasks. See
“What are the Distributed Systems Administration Utilities?” (page 34).
Managing the Running Cluster
This section describes some approaches to routine management of the cluster. Additional
tools and suggestions are found in Chapter 7, “Cluster and Package Maintenance.”
Checking Cluster Operation with Serviceguard Manager
You can check configuration and status information using Serviceguard Manager: from
the System Management Homepage (SMH), choose Tools-> Serviceguard
Manager.
Checking Cluster Operation with Serviceguard Commands
Serviceguard also provides several commands for control of the cluster:
• cmviewcl checks status of the cluster and many of its components. A non-root
user with the role of Monitor can run this command from a cluster node or see
status information in Serviceguard Manager.
• On systems that support CFS, the Veritas Cluster File System,
cfscluster status gives information about the cluster;cfsdgadm display
gives information about the cluster’s disk groups.
• cmrunnode is used to start Serviceguard on a node. A non-root user with the role
of Full Admin can run this command from a cluster node or through Serviceguard
Manager.
• cmhaltnode is used to manually stop a running node. (This command is also
used by shutdown(1m).) A non-root user with the role of Full Admin can run
this command from a cluster node or through Serviceguard Manager.
• cmruncl is used to manually start a stopped cluster. A non-root user with Full
Admin access can run this command from a cluster node, or through Serviceguard
Manager.
• cmhaltcl is used to manually stop a cluster. A non-root user with Full Admin
access, can run this command from a cluster node or through Serviceguard
Manager.
You can use these commands to test cluster operation, as in the following:
