[Beowulf] Diagnosing Discovery issue xCat

[Nick Evans]

Hi All,

I am sure i am just doing something silly as i haven't had an issue in the
past getting nodes discovered via the switch port lookup method.

Currently the newly booting node goes through the following steps

Get IP
Get the "xcat/xnba.kpxe" file
Download the Genisis discovery environment and boot into it
re-request IP
get certificate
initiate discovery

This then loops never actually discovering.
I have also attached the output of the messages file from the management
node.

Hardware is IBM dx360m4 node attached to Cisco WS-C3750G-48PS-S switch


Any pointers on where to look for anything that might shed some light on
this issue will be helpful.
Also do i need to specifically get the MIBS file for the switch as i don't
recall needing to to this in the past?

Thanks in advance
Nick
