Reviewing Cluster and Package Status
You can check status using Serviceguard Manager or from a cluster
node’s command line.
Reviewing Cluster and Package Status 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 use the cmviewcl command without root access; in clusters
running Serviceguard version A.11.16 or later, grant access by assigning
the Monitor role to the users in question. In earlier versions, allow access
by adding <nodename> <nonrootuser> to the cmclnodelist file.
cmviewcl -v 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.
You can also specify that the output should be formatted as it was in a
specific earlier release by using the -r option to specify the release
format you want, for example:
cmviewcl -r A.11.16
(See the cmviewcl (1m) manpage for the supported release formats.)
The formatting options let you choose a style: the tabulated format is
designed for viewing; the line format is designed for scripting, and is
easily parsed.
See the manpage for a detailed description of other cmviewcl options.
