Testing the installation
16 ParaStation5 Administrator's Guide
Alternatively, it is possible to use the single command form of the psiadmin command:
# /opt/parastation/bin/psiadmin -s -c "list"
The command should be repeated until all nodes are up. The ParaStation administration tool is described
in detail in the corresponding manual page psiadmin(1).
If some nodes are still marked as "down", the logfile /var/log/messages for this node should be
inspected. Entries like “psid: ....” at the end of the file may report problems or errors.
After bringing up all nodes, the communication can be tested using
# /opt/parastation/bin/test_nodes -np nodes
where nodes has to be replaced by the actual number of nodes within the cluster. After a while a result like
---------------------------------------
Master node 0
Process 0-31 to 0-31 ( node 0-31 to 0-31 ) OK
All connections ok
PSIlogger: done
should be reported. Of course the number '31' will be replaced by a the actual number of nodes given on
the command line, i.e. nodes-1.
in case of failure, test_nodes may give continuously results like
---------------------------------------
Master node 0
Process 0-2,4-6 to 0-7 ( node 0-2,4-6 to 0-7 ) OK
Process 3 to 0-6 ( node 3 to 0-6 ) OK
Process 7 to 0-2,4-7 ( node 7 to 0-2,4-7 ) OK
A detailed description of test_nodes can be found within the corresponding manual page test_nodes(1).
