wiping system from ok prompt
So last week I posted about my system that will not completely boot. It reports a bad trap and reboots in an endless cycle. I'm at a point where I just want to wipe the system clean, reload the software and basically start from scratch.
I can interrupt the boot cycle and get to an ok prompt. Is there a way to wipe the hard drive from there? Thanks!

lamclean
LAMCLEAN(1) LAM COMMANDS LAMCLEAN(1)
NAME
lamclean - Attempt to clean entire LAM system.
SYNTAX
lamclean [-hv]
OPTIONS
-h Print the command help menu.
-v Be verbose.
DESCRIPTION
The lamclean command attempts to remove all user processes and messages from all nodes. It also de-allocates all user allocated resources
and cancels all user process registrations. This happens by invoking many different remote services which have previously been invoked
individually by several other commands. These commands should still be used when partial selective removal of user presence is desired.
Otherwise, lamclean is a quick and convenient way of starting over after a bad application run without rebooting the system.
lamclean takes the following actions on the following system processes on all nodes:
kenyad The LAM SIGUDIE signal (terminate) is sent to all user processes. See doom(1).
bufferd The entire daemon is reset to its initial state after booting. See sweep(1).
filed All user file descriptors are closed. See fctl(1).
traced All traces are removed. See lamtrace(1).
lamclean will not succeed if any of the nodes are unreachable due to catastrophic failure or maximum buffer overflow with link jamming. If
lamclean does not return, use wipe(1) and lamboot(1) to restart the multicomputer.
