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
InfiniPath fabric. It must be run on a front end node, and requires specification of a
nodefile. For example:
InfiniPath 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
...
hostname2
...
ipath_checkout performs the following seven tests on the cluster:
1.
1.
Executes the ping command to all nodes to verify that they all are
reachable from the front end.
2.
Executes the ssh command to each node to verify correct configuration
of ssh.
3.
Gathers and analyzes system configuration from the nodes.
4.
Gathers and analyzes RPMs installed on the nodes. Missing RPMs can be
found this way.

NOTE:
The hostnames in the nodefile are Ethernet hostnames, not IPv4
addresses.

To create a nodefile, use the ibhosts program. It will generate a list
of available nodes that are already connected to the switch. The
