NAME

cplant_probe_node - see if a node is there, and if so, is it the one we expected


MODULE

cplant


SYNOPSIS

cplant_probe_node [--help] <nid>


DESCRIPTION

This script ``pings'' a remote host over the myrinet to verify connectivity. It also checks that the node at the other end is the expected node, to catch myrinet wiring problems. The route used for the ping is read from the MCP's current route table.


OPTIONS

--help Print this manpage.


NOTES

cplant_probe_node calls another script, rroute to perform the actual ping. rroute should (must?) be run as root. If you are getting error messages like ``No LANai devices available'', make sure you are running as root (effective userid 0) and try again.

Depending on the Cplant(tm) release you are running, you may need to adjust the $cplant path variable in this script to use ``rte/cplant'' or ``rte/nfs-cplant'' as necessary.


FILES

The default paths for location of the cluster configuration database, cloned directories, supporting libraries, and other settings are recorded in the CConf.pm config file. Set the environment variable CLUSTER_CONFIG to the location of CConf.pm, or use the default of /cluster/config
