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
Serviceguard Manager lets you see all the nodes and packages within a
cluster and displays their current status. Refer to the section on “Using
Serviceguard Manager” in Chapter 7. You can check configuration and
status information using Serviceguard Manager:
You can see if all configured nodes are running.
You can check that all configured packages are running, and see
what nodes they are running on.
You can get more information from the property sheets for cluster,
nodes, and packages.
When you create or modify a package or cluster configuration, you can
start the cluster running and archive its configuration in a Serviceguard
Manager (.sgm) file. The data in this file can be compared with later
versions of the cluster to understand the changes that are made over
time. It will be particularly useful in troubleshooting to compare this file
to a problem cluster.
There are several administrative commands you can use through
Serviceguard Manager, if the Session Server node and the target node
both have Serviceguard version A.11.12 or later installed.
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.
