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).
