There appears to be an issue with installation over an HP switch. Upon bootup, the network driver resets twice which somehow never allows the client to ask and therefore receive it's MAC address.
This follows the RH bug : https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=110036
Installation via a directly attached cable to the head node works fine.
I have emailed the Beowulf list in hopes that the problem was in some configuration of the switch but have recently come across this bug report and it appears that the symptoms are the same.
Are there any plans to roll these patches into CentOS 3.3 (x86_64) in the near future?
Thanks, Bill
