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 reg
istrations. This happens by invoking many different
remote services which have previously been invoked indi
vidually by several other commands. These commands should
still be used when partial selective removal of user pres
ence is desired. Otherwise, lamclean is a quick and con
venient way of starting over after a bad application run
without rebooting the system.
lamclean takes the following actions on the following sys
tem 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 unreach
able due to catastrophic failure or maximum buffer over
flow with link jamming. If lamclean does not return, use
wipe(1) and lamboot(1) to restart the multicomputer.
