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.
