Reviewing Cluster and Package States with
the cmviewcl Command
Information about cluster status is stored in the status database, which
is maintained on each individual node in the cluster. You can display
information contained in this database by issuing the cmviewcl
command:
# cmviewcl -v
You can issue the cmviewcl command with non-root access: In clusters
with Serviceguard version A.11.16 create a Monitor role in the cluster
configuration file. In earlier versions, add a non-root pair to the
cmclnodelist file (
<nodename> <nonrootuser>) .
The cmviewcl command, when issued with the -v option, displays
information about all the nodes and packages in a running cluster,
together with the settings of parameters that determine failover
behavior.
TIP Some commands take longer to complete in large configurations. In
particular, you can expect Serviceguard’s CPU usage to increase during
cmviewcl -v as the number of packages and services increases.
See the man page for a detailed description of other cmviewcl options.
