ClusterPack Tutorial

z
sysimage_register
z
sysimage_distribute
These scripts use ClusterPack's knowledge of the cluster configuration to simplify the creation
and distribution of system (golden) images. With the use of scripts, creating and distributing
images is as simple as running these three tools and providing the name of a host and/or path
of the image.

3.1.4 What are the MSA (Multi System Aware) Tools?
These utilities enable invoking common tasks on multiple nodes of the cluster from a single
p
oint. The following is a brief description of the utilities. For detailed information, refer to the
man pages.
z
clsh - Runs commands on one, some or all nodes in the cluster.
z
clcp - Copies files to one/some/all cluster nodes.
z
cluptime - Works like ruptime, only for all nodes in the cluster.
z
clps - Cluster-wide ps command.
z
clkill - Kills specified processes on specified nodes.
z
clinfo - Shows nodes and cluster information.
z
clgroup - Create a logical cluster group of nodes and propagate the group
information across all of the management tools in the cluster (PCC
Clusterware, SCM, SIM, etc.)

3.1.5 clsh - Runs commands on one, some, or all nodes in the cluster.
The clsh program runs a remote shell to each host in the compute cluster with the specified
command. The command to run is echoed to the user's screen each time one is launched. A
new command will not begin until the previous one is finished, i.e. these do not run in parallel.
Sending a SIGINT (usually a ^C) will cause the current host to be skipped, and sending a
SIGQUIT (usually a ^\) will immediately abort the whole clsh command.
Percent interpolation, as in clcp, is also supported.
