2.9.3 Debugging NIM Installations

Sometimes, the only way to discover a problem is by debugging NIM. This
procedure will help to precisely identify which step in the installation process is
failing. However, the actions needed to correct the problem will vary depending
on the failing step. The debug option is a low lever tool provided by creating a
spot in debug mode, which will let you run the installation process in a
step-by-step basis. Perform the following steps to debug the installation of your
nodes.

Then run to recreate the SPOT. Alternatively, you can run the
nim
following command:
# nim -o define -t spot -a server=master -a source=lppsource \
-a location=/usr psspspot
spbootins -r disk <Frame#> <Node#> <NumberOfNodes>
This command resets the specified nodes to disk and calls all necessary NIM
commands to reset the install configuration. Always use this command to
start your new configuration from a well-defined point.
nim -Fo check -a debug=yes psspspot
This command creates the SPOT in debug mode.
lsnim -l psspspot
Display the attributes of the SPOT resource and look for a line containing the
