RedHat 9 (Linux i386) - man page for wipe (redhat section 1)

WIPE(1) 				    LAM TOOLS					  WIPE(1)

NAME
       wipe - Shutdown LAM.

SYNTAX
       wipe [-bdhv] [-n <#>] [<bhost>]

OPTIONS
       -b	   Assume  local  and remote shell are the same.  This means that only one remote
		   shell invocation is used to each node.  If -b is not used,  two  remote  shell
		   invocations are used to each node.

       -d	   Turn on debugging mode.  This implies -v.

       -h	   Print the command help menu.

       -v	   Be verbose.

       -n <#>	   Wipe only the first <#> nodes.

DESCRIPTION
       This  command  has  been  deprecated in favor of the lamhalt command.  wipe should only be
       necessary if lamhalt fails and is unable to clean up the LAM  run-time  environment  prop-
       erly.   The wipe tool terminates the LAM software on each of the machines specified in the
       boot schema, <bhost>.  wipe is the topology tool that terminates LAM on the UNIX(tm) nodes
       of  a  multicomputer  system.   It  invokes  tkill(1) on each machine.  See tkill(1) for a
       description of how LAM is terminated on each node.

       The <bhost> file is a LAM boot schema written in the host file syntax.  CPU counts in  the
       boot  schema  are  ignored  by  wipe.   See bhost(5).  Instead of the command line, a boot
       schema can be specified in the LAMBHOST environment variable.  Otherwise a  default  file,
       bhost.def, is used.  LAM searches for <bhost> first in the local directory and then in the
       installation directory under etc/.

       wipe does not quit if a particular remote node cannot be reached or if tkill(1)	fails  on
       any  node.  A message is printed if either of these failures occur, in which case the user
       should investigate the cause of failure and, if necessary, terminate LAM by manually  exe-
       cuting  tkill(1) on the problem node(s).  In extreme cases, the user may have to terminate
       individual LAM processes with kill(1).

       wipe will terminate after a limited number of nodes if the -n option is	given.	 This  is
       mainly  intended  for  use by lamboot(1), which invokes wipe when a boot does not success-
       fully complete.

EXAMPLES
       wipe -v mynodes
	   Shutdown LAM on the machines described in the  boot	schema,  mynodes.   Report  about
	   important steps as they are done.

FILES
       $LAMHOME/etc/lam-bhost.def	 default boot schema file
