3–TrueScale Cluster Setup and Administration Checking Cluster and <strong>Software</strong> Status ipath_checkout ipath_checkout is a bash script that verifies that the installation is correct and that all the nodes of the network are functioning and mutually connected by the TrueScale fabric. It must be run on a front end node, and requires specification of a nodefile. For example: $ ipath_checkout [options] nodefile The nodefile lists the hostnames of the nodes of the cluster, one hostname per line. The format of nodefile is as follows: hostname1 hostname2 ... For more information on these programs, see “ipath_control” on page I-12, “ibstatus” on page I-7, and “ipath_checkout” on page I-10. D000046-005 B 3-37
