A remote command can be executed on one or more nodes in the cluster from any node by using
the 'clsh' command in /opt/clusterpack/bin.
Some examples of clsh usage are:
z
Invoke 'uname -a' on all cluster nodes
% clsh uname -a
z
Invoke 'uname -a' on node1
% clsh -C node1 uname -a
z
Invoke 'uname -a' on all nodes in the cluster group 'sub1'
% clsh -C sub1 uname -a
z
Invoke 'uname -a' on node1 and node3
% clsh -C node1+node3 uname -a
For more details on the usage of clsh, invoke the command.
% man clsh

1.6.13 Copy files within nodes in a cluster
The 'clcp' command in /opt/clusterpack/bin is used to copy files between cluster nodes. Each file
or directory argument is either a remote file name of the form "%h:path" or "cluster:path" or a
local file name (containing no ':' characters).
Some examples of clcp usage are:
z
Update /etc/checklist on all nodes with the local /etc/checklist
%
clcp /etc/checklist %h:/etc/checklist
%
clcp /etc/checklist cluster:/etc/checklist
