pdsh Utility Wrappers
Administrators can build wrapper commands around pdsh for commands
that are frequently used across multiple systems and Serviceguard
clusters. Several such wrapper commands are provided with DSAU.
These wrappers are Serviceguard cluster-aware and default to fanning
out cluster-wide when used in a Serviceguard environment. These
wrappers support most standard pdsh command line options and also
support long options (-- option syntax) .
cexec cexec is a general purpose pdsh wrapper. In addition
to the standard pdsh features, cexec includes a
reporting feature. Use the --report_loc option to
have cexec display the report location for a command.
The command report records the command issued in
addition to the nodes where the command succeeded,
failed, or the nodes that were unreachable. The report
can be used with the --retry option to replay the
command against nodes that failed, succeeded, were
unreachable, or all nodes.
ccp ccp is a wrapper for pdcp and copies files cluster-wide
or to the specified set of systems.
cps cps fans out a ps command across a set of systems or
cluster.
ckill ckill allows the administrator to signal a process by
name since the pid of a specific process will vary across
a set of systems or the members of a cluster.
cuptime cuptime displays the uptime statistics for a set of
systems or a cluster.
All the wrappers support the CFANOUT_HOSTS environment variable
when not executing in a Serviceguard cluster. The environment variable
specifies a file containing the list of hosts to target, one hostname per
line. This will be used if no other host specifications are present on the
command line. When no target nodelist command line options are used
and CFANOUT_HOSTS is undefined, the command will be executed on
the local host.
For more information on these commands please refer to their reference
manpages.
